5.1 The impact test has been found useful in laboratory simulation of impacts such as those encountered in manual and mechanical handling and transportation. The impact test simulates some types of shocks that could occur in the handling of packages or shipping units and helps evaluate the ability of the package to protect the contents against these shocks. The test may also permit observation of progressive failure of a package and damage to the contents.5.2 The test results within a given laboratory using this test method may be useful for evaluating and comparing packages. However, because of the variability of test machines that have been used in the past, especially the impact surface (backstop), it has been found that interlaboratory correlation of test results has been poor.5.3 These procedures are not intended to simulate rail car coupling environment. Refer to Test Method D4003 and Test Methods D5277.5.4 This test method fulfills the requirement of ISO 2244.NOTE 1: ISO 2244 may not meet the requirements for this test method.1.1 This test method covers two procedures for conducting impact tests on loaded containers or shipping units (pallet loads), as follows:1.1.1 Procedure A, to test the ability of a container or shipping unit to withstand impacts, and1.1.2 Procedure B, to test the ability of a container or shipping unit or interior packing, or both, to provide protection to the contents, when subjected to impacts.1.2 Either of these two procedures may be used to evaluate different designs of containers of the same size and carrying the same load. These procedures are suitable for testing various types of containers such as boxes, crates, barrels, drums, kegs, bags, sacks, or pails made of various materials or combinations of materials and for shipping units such as pallet loads or palletized units.1.3 The procedures described in this test method are particularly suitable for testing large or heavily loaded containers.1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Note 1 and Section 7.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5265-23 Standard Test Method for Bridge Impact Testing Active 发布日期 :  1970-01-01 实施日期 : 

4.1 Materials shipped in elongated packages are liable to damage as a result of impact near their midpoint when only the ends are supported. This type of damage can occur during the shipment of packaging of mixed dimensions. It is particularly prevalent during conveyer line transport and sortation. This test method provides a means of determining resistance to such damage.1.1 This test method is intended to determine the capability of a long package with a narrow cross-section to resist impact near its center when the package is supported only at its ends. This test method allows the user to select from two test options: Option A employs the use of a free-fall drop tester (see Exhibit B), and Option B employs the use of simulated mechanical impact testing equipment (S.M.I.T.E.; see Exhibit A). The two optional procedures are designed to impart the same amount of kinetic energy at impact; therefore, each procedure yields equal damage-producing potential.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The spectrum of the noise in the room below the test specimen is determined by the following:5.1.1 The size and the mechanical properties of the floor-ceiling assembly, such as its construction, surface, mounting or edge restraints, stiffness, or internal damping,5.1.2 The acoustical response of the room below,5.1.3 The placement of the object or device producing the impacts, and5.1.4 The nature of the actual impact itself.5.2 This test method is based on the use of a standardized tapping machine of the type specified in 8.1 placed in specific positions on the floor. This machine produces a continuous series of uniform impacts at a uniform rate on a test floor and generates in the receiving room broadband sound pressure levels that are sufficiently high to make measurements possible beneath most floor types even in the presence of background noise. The tapping machine itself, however, is not designed to simulate any one type of impact, such as produced by male or female footsteps.5.3 Because of its portable design, the tapping machine does not simulate the weight of a human walker. Therefore, the structural sounds, i.e., creaks or booms of a floor assembly caused by such footstep excitation is not reflected in the single number impact rating derived from test results obtained by this test method. The degree of correlation between the results of tapping machine tests in the laboratory and the subjective acceptance of floors under typical conditions of domestic impact excitation is uncertain. The correlation will depend on both the type of floor construction and the nature of the impact excitation in the building.5.4 In laboratories designed to satisfy the requirements of this test method, the intent is that only significant path for sound transmission between the rooms is through the test specimen. This is not generally the case in buildings where there are often many other paths for sounds— flanking sound transmission. Consequently sound ratings obtained using this test method do not relate directly to sound isolation in buildings; they represent an upper limit to what would be measured in a field test.5.5 This test method is not intended for field tests. Field tests are performed according to Test Method E1007.1.1 This test method covers the laboratory measurement of impact sound transmission of floor-ceiling assemblies using a standardized tapping machine. It is assumed that the test specimen constitutes the primary sound transmission path into a receiving room located directly below and that a good approximation to a diffuse sound field exists in this room.1.2 Measurements may be conducted on floor-ceiling assemblies of all kinds, including those with floating-floor or suspended ceiling elements, or both, and floor-ceiling assemblies surfaced with any type of floor-surfacing or floor-covering materials.1.3 This test method prescribes a uniform procedure for reporting laboratory test data, that is, the normalized one-third octave band sound pressure levels transmitted by the floor-ceiling assembly due to the tapping machine.1.4 Laboratory Accreditation—The requirements for accrediting a laboratory for performing this test method are given in Annex A2.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 This test method provides a procedure for evaluating the potential resistance to degradation by impact and abrasion of pervious concrete mixtures. A common failure mode of pervious concrete pavements is raveling. This test allows the comparison of the relative potential resistance to raveling of pervious concrete mixtures of varying proportions and raw materials. In addition, in the field, raveling is caused by improper paste consistency, workability loss, inadequate compaction, and improper curing—this test method does not address any of these causes. There is no known correlation between this test method and the field performance of pervious concrete.5.1.1 This information may be used to compare proposed mixture proportions, yet to be placed, but is not intended to be used for mixture qualification or jobsite acceptance testing.5.1.2 This test method is applicable to pervious concrete mixtures containing coarse aggregate with a nominal maximum size of 25 mm [1 in.] or smaller.5.1.3 This test method is only applicable to cylindrical specimens cast as described herein. The precision and bias have not been evaluated for drilled cores.1.1 This test method covers determining the potential resistance to degradation of pervious concrete by measuring the mass loss of specimens subjected to combined action of impact and abrasion in a rotating steel drum.1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3 The text of this test method references notes and footnotes that provide explanatory information. These notes and footnotes (excluding those in tables) shall not be considered as requirements of this test method.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged use.2)

5.1 Susceptibility to damage from concentrated out-of-plane impact forces is one of the major design concerns of many structures made of advanced composite laminates. Knowledge of the damage resistance properties of a laminated composite plate is useful for product development and material selection.5.2 Drop-weight impact testing can serve the following purposes:5.2.1 To establish quantitatively the effects of stacking sequence, fiber surface treatment, variations in fiber volume fraction, and processing and environmental variables on the damage resistance of a particular composite laminate to a concentrated drop-weight impact force or energy.5.2.2 To compare quantitatively the relative values of the damage resistance parameters for composite materials with different constituents. The damage response parameters can include dent depth, damage dimensions, and through-thickness locations, F1, Fmax, E1, and Emax, as well as the force versus time curve.5.2.3 To impart damage in a specimen for subsequent damage tolerance tests, such as Test Method D7137/D7137M.5.3 The properties obtained using this test method can provide guidance in regard to the anticipated damage resistance capability of composite structures of similar material, thickness, stacking sequence, and so forth. However, it must be understood that the damage resistance of a composite structure is highly dependent upon several factors, including geometry, thickness, stiffness, mass, support conditions, and so forth. Significant differences in the relationships between impact force/energy and the resultant damage state can result due to differences in these parameters. For example, properties obtained using this test method would more likely reflect the damage resistance characteristics of an unstiffened monolithic skin or web than that of a skin attached to substructure which resists out-of-plane deformation. Similarly, test specimen properties would be expected to be similar to those of a panel with equivalent length and width dimensions, in comparison to those of a panel significantly larger than the test specimen, which tends to divert a greater proportion of the impact energy into elastic deformation.5.4 The standard impactor geometry has a blunt, hemispherical striker tip. Historically, for the standard laminate configuration and impact energy, this impactor geometry has generated a larger amount of internal damage for a given amount of external damage, when compared with that observed for similar impacts using sharp striker tips. Alternative impactors may be appropriate depending upon the damage resistance characteristics being examined. For example, the use of sharp striker tip geometries may be appropriate for certain damage visibility and penetration resistance assessments.5.5 The standard test utilizes a constant impact energy normalized by specimen thickness, as defined in 11.7.1. Some testing organizations may desire to use this test method in conjunction with D7137/D7137M to assess the compressive residual strength of specimens containing a specific damage state, such as a defined dent depth, damage geometry, and so forth. In this case, the testing organization should subject several specimens, or a large panel, to multiple low velocity impacts at various impact energy levels using this test method. A relationship between impact energy and the desired damage parameter can then be developed. Subsequent drop weight impact and compressive residual strength tests can then be performed using specimens impacted at an interpolated energy level that is expected to produce the desired damage state.1.1 This test method determines the damage resistance of multidirectional polymer matrix composite laminated plates subjected to a drop-weight impact event. The composite material forms are limited to continuous-fiber reinforced polymer matrix composites, with the range of acceptable test laminates and thicknesses defined in 8.2.1.1.1 Instructions for modifying these procedures to determine damage resistance properties of sandwich constructions are provided in Practice D7766/D7766M.1.2 A flat, rectangular composite plate is subjected to an out-of-plane, concentrated impact using a drop-weight device with a hemispherical impactor. The potential energy of the drop-weight, as defined by the mass and drop height of the impactor, is specified prior to test. Equipment and procedures are provided for optional measurement of contact force and velocity during the impact event. The damage resistance is quantified in terms of the resulting size and type of damage in the specimen.1.3 The test method may be used to screen materials for damage resistance, or to inflict damage into a specimen for subsequent damage tolerance testing. When the impacted plate is tested in accordance with Test Method D7137/D7137M, the overall test sequence is commonly referred to as the Compression After Impact (CAI) method. Quasi-static indentation per Test Method D6264/D6264M may be used as an alternate method of creating damage from an out-of-plane force and measuring damage resistance properties.1.4 The damage resistance properties generated by this test method are highly dependent upon several factors, which include specimen geometry, layup, impactor geometry, impactor mass, impact force, impact energy, and boundary conditions. Thus, results are generally not scalable to other configurations, and are particular to the combination of geometric and physical conditions tested.1.5 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.5.1 Within the text, the inch-pound units are shown in brackets.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Tensile-impact energy is the energy required to break a standard tension-impact specimen in tension by a single swing of a standard calibrated pendulum under a set of standard conditions (see Note 2). To compensate for the minor differences in cross-sectional area of the specimens, the energy to break is normalized to units of kilojoules per square metre (or foot-pounds-force per square inch) of minimum cross-sectional area. An alternative approach to normalizing the impact energy that compensates for these minor differences and still retains the test unit as joules (foot-pounds) is shown in Section 10. For a perfectly elastic material, the impact energy is usually reported per unit volume of material undergoing deformation. However, since much of the energy to break the plastic materials for which this test method is written is dissipated in drawing of only a portion of the test region, such normalization on a volume basis is not feasible. In order to observe the effect of elongation or rate of extension, or both, upon the result, the test method permits two specimen geometries. Results obtained with different capacity machines generally are not comparable.5.1.1 With the Type S (short) specimen the extension is comparatively low, while with the Type L (long) specimen the extension is comparatively high. In general, the Type S specimen (with its greater occurrence of brittle fracture) gives greater reproducibility, but less differentiation among materials.NOTE 2: Friction losses are largely eliminated by careful design and proper operation of the testing machine.5.2 Scatter of data is sometimes attributed to different failure mechanisms within a group of specimens. Some materials exhibit a transition between different failure mechanisms. If so, the elongation will be critically dependent on the rate of extension encountered in the test. The impact energy values for a group of such specimens will have an abnormally large dispersion.5.2.1 Some materials retract at failure with insignificant permanent set. With such materials, determining the type of failure, ductile or brittle, by examining the broken pieces is difficult, if not impossible. It is helpful to sort a set of specimens into two groups by observing the broken pieces to ascertain whether or not there was necking during the test. Qualitatively, the strain rates encountered here are intermediate between the high rate of the Izod test of Test Methods D256 and the low rate of usual tension testing in accordance with Test Method D638.5.3 The energy for fracture is a function of the force times the distance through which the force operates. Therefore, given the same specimen geometry, it is possible that one material will produce tensile-impact energies for fracture due to a large force associated with a small elongation, and another material will produce the same energy for fracture result due to a small force associated with a large elongation. It shall not be assumed that this test method will correlate with other tests or end uses unless such a correlation has been established by experiment.5.4 Comparisons among specimens from different sources are to be made with confidence only to the extent that specimen preparation, for example, molding history, has been precisely duplicated. Comparisons between molded and machined specimens must not be made without first establishing quantitatively the differences inherent between the two methods of preparation.5.5 Only results from specimens of nominally equal thickness and tab width shall be compared unless it has been shown that the tensile-impact energy normalized to kilojoules per square metre (or foot-pounds-force per square inch) of cross-sectional area is independent of the thickness over the range of thicknesses under consideration.5.6 The bounce of the crosshead supplies part of the energy to fracture test specimen (see Appendix X1).5.7 For many materials, there are specifications that require the use of this test method, but with some procedural modifications that take precedence when adhering to the specification. Therefore, it is advisable to refer to that material specification before using this test method. Table 1 of Classification System D4000 lists the ASTM materials standards that currently exist.1.1 This test method covers the determination of the energy required to rupture standard tension-impact specimens of plastic materials. Rigid materials are suitable for testing by this method as well as specimens that are too flexible or thin to be tested in accordance with other impact test methods.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.NOTE 1: This test method and ISO 8256 address the same subject matter, but differ in technical content.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This practice establishes a standard impact assessment methodology to enable entities to uniformly ascertain and communicate impact levels associated with the potential loss of MDSDs. This practice is not intended to prescribe specific information security policies for entities or organizations. This practice assumes that individuals and entities are following all relevant information security policies as required by federal or state law, the terms of applicable government contracts, specific agency policies such as the National Industrial Security Program Operating Manual (NISPOM), and entity-specific policies.This practice assumes, but does not require, that entities have devised and are maintaining a system of internal controls over MDSDs in accordance with the section on Management of Property of Practice E 2279.This practice assumes, but does not require, that the results of this impact assessment will inform future actions and help entities determine cost-effective property control measures for MDSDs commensurate with the potential consequences of their loss in accordance with the section on Management of Property of Practice E 2279.This practice encourages an inclusive understanding and communication of the risk associated with MDSDs and, by assigning a rating to the impact of loss, enables comparisons on this basis to other MDSDs rated using the same practice.This practice is intended to foster and enable additional standard practices related to or based on these terms and concepts.1.1 This practice describes a methodology for assessing and quantifying the impact of the loss of mobile data storage devices (MDSDs), for example, thumb drives, auxiliary hard drives, and other property containing personally identifiable information or other entity sensitive information.1.2 This practice is based on two concepts:1.2.1 Identifying the MDSDs that pose the greatest risk to the organization based on both the information that is stored on them and the location in which they are used, and1.2.2 Determining the impact of the potential loss of specific MDSDs. In general, this impact assessment is best practiced as a part of a larger risk management process. While this practice does not address this larger topic, it may inform other risk management standards.1.3 This practice is intended to be applicable and appropriate for all asset-holding entities.1.4 In accordance with the provisions of Practice E 2279, this practice clarifies and enables effective and efficient control and tracking of equipment.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 This guide applies to the determination of the safety of non-metallic materials used in contact with biotechnology product containing solutions. Process materials leach low level of residues into water, cell culture media, buffers, and other product containing solutions. This document offers guidance on determining the safety of these materials (process materials) for use. The goal is to prevent toxic extractables from entering process streams and ultimately contaminating the final product in unacceptable levels.4.2 The purpose of this guide is to describe tests to qualify materials with respect to any extractable substances so as to prevent unintentional introduction of a potential source of objectionable substances. An extractable material is objectionable if it is toxic, interacts with product constituents, interferes with required assays, or otherwise affects the process stream so as to adversely affect critical quality parameters, for example, purity, safety, efficacy, identity, strength of the final product or its successful production. All organizations producing pharmaceutical products should consider the points in this guide when qualifying process materials for use in their production processes.4.3 This guide outlines the application of the process material tests primarily in ASTM or USP. Typical process materials include high molecular weight polymers and solids such as hoses, filters, filter housings, containers, valve diaphragms, gaskets, o-rings, chromatography resins, and chromatographic columns.4.4 The battery of tests described in this guide is intended to cover a wide variety of potential attributes of materials and to characterize possible extractables.4.5 The material specification will vary depending on the impact on the final product and the point in the process that the product solution contacts the material. Tighter specifications should be considered for extractables for final product purification process materials than for fermentation media process materials.1.1 This guide covers procedures and test methods for process component qualification by the end user. The goal is to assess the safety impact of extractables from non-metallic process components used in contact with bioprocessing solutions. This encompasses the impact of extractables on the safety of the final product as it passes through the various stages of the manufacturing process. This guide is not designed for evaluation of metallic materials, final product container/closures or those components intentionally added to the product or production streams during the manufacturing process. Testing of solids and extracts is specified in other ASTM standards. Materials must be qualified by specific use.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 There is no companion guide available.1.4 Safety/Fire Hazards: Extractions with organic solvents will be infrequent under this guide, but, when used must be treated as potential fire/explosion hazards.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method covers a comparative measurement method for impact absorption properties for body padding and protective wear (apparel) for the sport of fencing. The apparel includes fencing mask bibs, underarm protectors or plastrons, padded vests, uniform jackets, knickers or trousers, gloves, and other protection worn to protect against impacts from the fencing weapon's tip (for example, touches) for foil, saber, or epee. The scope of this test method excludes measurement or performance for perforation resistance of the blade, whether in tact or broken. Note 1-This is a simple test method to discriminate between qualities of different padding materials or systems under an impact that simulates the delivery of a fencing touch. It does not purport to measure quantitative impact energy absorption values at thrust sites. Until in-field data become available, this standard allows manufacturers to intercompare padding systems, fabrics, materials, or composites for protective fencing wear for integrity, robustness, and impact attenuation. 1.2 This standard does not purport to address all of the safety problems associated with fencing padding and will not prevent all injuries due to blades impacting fencers. It is the responsibility of the users of the protective padding to establish appropriate safety practices, including maintaining safe fencing distances and care and inspection of the protective wear as well as the blade. Specifically, this standard does not address degradation of the protective padding with use and laundering, or performance of the padding for puncture resistance by thrusts involving in-tact or broken blades. It should be recalled that the sport derives from duelling and is inherently not free of risk of injury or death .
