4.1 Compressive resistance is one of the properties used to evaluate the ability of shipping containers, components, and unit loads to successfully survive the compressive forces they are subjected to during storage and distribution (see Note 1).NOTE 1: For constant load test refer to Test Method D4577.4.2 Compressive resistance may be determined with either fixed- or swiveled-platen-type testing machines. However, a fixed-head compression machine is required to perform edge-to-edge and corner-to-corner orientations on test specimens (see Note 2). Also, unit loads are generally tested only in the top-to-bottom orientation.NOTE 2: Fixed-platen machines generally cause corrugated box specimens to fail at their strongest point, while swivel-platen machines cause corrugated box specimens to fail at their weakest point.5 The swiveled platen is allowed to move to the weakest point of the container.1.1 This test method covers compression tests on shipping containers (for example, boxes and drums) or components, or both. Shipping containers may be tested with or without contents. The procedure may be used for measuring the ability of the container to resist external compressive loads applied to its faces, to diagonally opposite edges, or to corners. This test method covers testing of multiple containers or unit loads, in addition to individual shipping containers, components, materials, or combination thereof.1.2 The test method of applying load may be used to compare the characteristics of a given design of container with a standard, or to compare the characteristics of containers differing in construction.1.3 This test method is related to TAPPI T 804. This test method fulfills the requirements of International Organization for Standardization (ISO) Test Method 12048. The ISO standards may not meet the requirements for this test method.1.4 The test may be conducted with the container loaded with contents and interior packaging in cases where the contents share the load.1.5 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.1.6 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.

3.1 This practice is applicable to the calculation of stresses seen on a knee tibial component when loaded in a manner described in this practice. This practice can be used to identify the worst-case size for a particular implant. When stresses calculated using this FEA method were compared to the stresses measured at two locations on the tibial tray using physical strain gauging techniques performed at one laboratory, the difference observed was -6.8 % at one location (with the strain gauges reporting the higher stress) and 3.1 % at the other location (with the FEA method reporting a higher stress). This difference should be considered when determining the worst-case size(s) of the same implant design.3.2 The loading of tibial tray designs in vivo will, in general, differ from the loading defined in this practice. However, this practice is designed to allow for comparisons between the fatigue performance of different metallic tibial component designs, when tested under similar conditions.1.1 This practice establishes requirements and considerations for the numerical simulation of metallic orthopaedic total knee tibial components using Finite Element Analysis (FEA) techniques for the estimation of stresses and strains. This practice is only applicable to stresses below the yield strength, as provided in the material certification.1.2 Purpose—This practice establishes requirements and considerations for the development of finite element models to be used in the evaluation of metallic orthopaedic total knee tibial component designs for the purpose of prediction of the static implant stresses and strains. This procedure can be used for worst-case assessment within a series of different implant sizes of the same implant design to reduce the physical test burden. Recommended procedures for performing model checks and verification are provided as an aid to determine if the analysis follows recommended guidelines. Finally, the recommended content of an engineering report covering the mechanical simulation is presented.1.3 Limits—This practice is limited in discussion to the static structural analysis of metallic orthopaedic total knee tibial components (which excludes the prediction of fatigue strength).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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.

4.1 This practice covers bearings and bearing components of all material compositions and grades. It may be used to develop a process for adequately handling bearings.4.2 Unless the proper conditions of an adequate facility, equipment, and trained personnel are available, it may be better not to inspect the bearings in-house. The danger of contaminating and damaging the bearings may be much greater than the possibility of receiving bearings that will not function.4.3 Bearings are easily damaged at the customers' receiving and test areas. In most cases, bearings should be accepted based on the bearing manufacturer’s certification. Certificates of quality (conformance) supplied by the bearing manufacturer may be furnished in lieu of actual performance of such testing by the receiving activity of the bearings. The certificate shall include the name of the purchaser, contract number/PO number, name of the manufacturer or supplier, item identification, name of the material, lot number, lot size, sample size, date of testing, test method, individual test results, and the specification requirements.4.4 This practice does not cover clean room requirements of miniature and instrument precision bearings. These bearings require clean room environments in accordance with ISO 14644-1 and ISO 14644-2.1.1 This practice covers requirements for the handling of all bearings and bearing components.1.2 This is a general practice. The individual bearing handling requirements shall be as specified herein or as specified in the contract or purchase order. In the event of any conflict between requirements of this practice and the individual bearing requirements of an OEM drawing, procurement specification, or other specification, the latter shall govern. Many companies, organizations, and bearing users have excellent facilities, equipment, and knowledgeable personnel for handling bearings. The thrust of this practice is for users that do not have this knowledge of bearings.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 specification covers the standard requirements for low-carbon age-hardened nickel-copper-chromium-molybdenum-columbium alloy steel forgings for pressure vessel components. Materials shall be manufactured to a killed fine austenitic grain size, by vacuum degas melting process. Heat treatment shall be conducted, according to class, by: normalizing and precipitation hardening (Grade A, Class 1); liquid quenching and precipitation hardening (Grade A, Class 2); or double liquid-quenching, tempering, double austenitizing, and precipitation hardening (Grade B). Heat and product analyses shall be used to evaluate the conformance of forgings to required chemical compositions. Tensile, notch toughness, and Charpy impact requirements shall be examined, for which one of four sampling methods may be employed. One tension test and one impact test (for three samples) shall be made for each forging. Dimensions and finishes of the forgings shall conform to that specified by the purchaser. Repair welding shall also be performed only if permitted by the purchaser.1.1 This specification covers requirements for low-carbon age-hardening nickel-copper-chromium-molybdenum-columbium alloy steel forgings for pressure vessel components.1.2 Forgings under this specification are available as Grades A or B. Grade A may be ordered in one or two classes as follows:1.2.1 Grade A Class 1—Normalized-and-precipitation-heat-treated, providing a minimum yield strength of 55 ksi [380 MPa] and a minimum tensile strength of 65 ksi [450 MPa].1.2.2 Grade A Class 2—Quenched-and-precipitation-heat-treated, providing a minimum yield strength of 65 ksi [450 MPa] and a minimum tensile strength of 75 ksi [515 MPa].1.2.3 Grade A was the original steel composition in this specification.1.3 Although the material is readily weldable, welding procedures are of fundamental importance and must be such as not to affect adversely the properties of the material, especially in the heat-affected zone. It is presupposed that welding procedures will be suitable for the material being welded.1.4 Supplementary requirements, including those applicable in Specification A788/A788M, are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.1.5 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.1.6 This specification is expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished to inch-pound units.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 Traditionally, HFTs have been incorporated into laboratory testing devices, such as the heat flow meter apparatus (Test Method C518), that employ controlled temperatures and heat flow paths to effect a thermal measurement. The application of heat flux transducers and temperature transducers to building components in situ can produce quantitative information about building thermal performance that reflects the existing properties of the building under actual thermal conditions. The literature contains a sample of reports on how these measurements have been used (1-8).35.2 The major advantage of this practice is the potential simplicity and ease of application of the sensors. To avoid spurious information, users of HFTs shall: (1) employ an appropriate S, (2) mask the sensors properly, (3) accommodate the time constants of the sensors and the building components, and (4) account for possible distortions of any heat flow paths attributable to the nature of the building construction or the location, size, and thermal resistance of the transducers.5.3 The user of HFTs and TTs for measurements on buildings shall understand principles of heat flux in building components and have competence to accommodate the following:5.3.1 Choose sensor sites using building plans, specifications and thermography to determine that the measurement represents the required conditions.5.3.2 A single HFT site is not representative of a building component. The measurement at an HFT site represents the conditions at the sensing location of the HFT. Use thermography appropriately to identify average and extreme conditions and large surface areas for integration. Use multiple sensor sites to assess overall performance of a building component.5.3.3 A given HFT calibration is not applicable for all measurements. The HFT disturbs heat flow at the measurement site in a manner unique to the surrounding materials (9, 10); this affects the conversion constant, S, to be used. The user shall take into account the conditions of measurement as outlined in 7.1.1. In extreme cases, the sensor is the most significant thermal feature at the location where it has been placed, for example, on a sheet metal component. In such a case, meaningful measurements are difficult to achieve. The user shall confirm the conversion factor, S, prior to use of the HFT to avoid calibration errors. See Section 7.5.3.4 The user shall be prepared to accommodate non-steady-state thermal conditions in employing the measurement technique described in this practice. This requires obtaining data over long periods, perhaps several days, depending on the type of building component and on temperature changes.5.3.5 Heat flux has a component parallel to the plane of the HFT. The user shall be able to minimize or accommodate this factor.1.1 This practice covers a technique for using heat flux transducers (HFTs) and temperature transducers (TTs) in measurements of the in-situ dynamic or steady-state thermal behavior of opaque components of building envelopes. The applications for such data include determination of thermal resistances or of thermal time constants. However, such uses are beyond the scope of this practice (for information on determining thermal resistances, see Practice C1155).1.2 Use infrared thermography with this technique to locate appropriate sites for HFTs and TTs (hereafter called sensors), unless subsurface conditions are known.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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 is suitable for determination of the total amount of extractable residue in metallic medical components. Extractable residue includes aqueous and non-aqueous residue, as well as non-soluble residue.5.2 This test method recommends the use of a sonication technique to extract residue from the medical component. Other techniques, such as solvent reflux extraction, could be used but have been shown to be less efficient in some tests, as discussed in X1.2.5.3 This test method is not applicable for evaluating the extractable residue for the reuse of a single-use component (SUD).1.1 This test method covers the quantitative assessment of the amount of residue obtained from metallic medical components when extracted with aqueous or organic solvents.1.2 This test method does not advocate an acceptable level of cleanliness. It identifies two techniques to quantify extractable residue on metallic medical components. In addition, it is recognized that this test method may not be the only method to determine and quantify extractables.1.3 Although these methods may give the investigator a means to compare the relative levels of component cleanliness, it is recognized that some forms of component residue may not be accounted for by these methods.1.4 The applicability of these general gravimetric methods have been demonstrated by many literature reports; however, the specific suitability for applications to all-metal medical components will be validated by an Interlaboratory Study (ILS) conducted according to Practice E691.1.5 This test method is not intended to evaluate the residue level in medical components that have been cleaned for reuse. This test method is also not intended to extract residue for use in biocompatibility testing.NOTE 1: For extraction of samples intended for the biological evaluation of devices or materials, refer to ISO 10993–12.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 This standard may involve hazardous or environmentally-restricted materials, operations, and equipment.

5.1 These test methods are intended to estimate the performance of upholstered furniture under conditions of exposure to a smoldering cigarette. This is accomplished by testing furniture component assemblies. However, interactions between components in production furniture are not necessarily predicted by component assembly testing.5.2 These test methods are not intended to measure the performance of upholstered furniture under conditions of open flame exposure, and do not indicate whether the furniture will resist the propagation of flame under severe fire exposure or when tested in a manner that differs substantially from the test standard.5.3 The results obtained with a material component tested in mock-up, in accordance with these test methods, do not necessarily indicate the performance of the same material component in other geometric configurations, such as in full-size furniture.1.1 This is a fire-test-response standard.1.2 These test methods are designed for the assessment of the resistance of upholstered furniture component assemblies to combustion after exposure to smoldering cigarettes under specified conditions.1.3 The tests apply to upholstered furniture components—cover fabrics, interior fabrics, welt cords, decking materials, barrier materials, and filling or padding materials including but not limited to: battings of natural or man-made fibers, foamed or cellular filling materials, resilient pads of natural or man-made fibers, and loose particulate filling materials (such as shredded polyurethane or feathers and down).1.4 The individual test methods and the materials to which they apply are as follows:1.4.1 Cover Fabric Test—Applies to outer cover fabrics (see Sections 10 and 11).1.4.2 Interior Fabric Test—Applies to interior fabrics used in intimate contact with outer fabrics (see Sections 12 and 13).1.4.3 Welt Cord Test—Applies to welt cord (see Sections 14 and 15).1.4.4 Filling/Padding Component Test—Applies to resilient materials used under the cover fabric in seats or in inside vertical walls (inside arm and inside backs) (see Sections 16 and 17).1.4.5 Decking Materials Test—Applies to resilient materials used in the deck under loose cushions (see Sections 18 and 19).1.4.6 Barrier Materials Test—Applies to materials that are intended to serve as a barrier between cover fabric and conventional polyurethane foam (see Sections 20 and 21).1.5 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.1.6 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 Radiation Shielding Window Components: 4.1.1 Radiation shielding window components operability and long-term integrity are concerns that originate during the design and fabrication sequences. Such concerns can only be addressed, or are most efficiently addressed, during one or the other of these stages. The operability and integrity can be compromised during handling and installation sequences. For this reason, the subject equipment should be handled and installed under closely controlled and supervised conditions.4.1.2 This standard is intended as a supplement to other standards and to federal and state regulations, codes, and criteria applicable to the design of radiation shielding window components.1.1 Intent: 1.1.1 The intent of this standard is to provide guidance for the design, fabrication, quality assurance, inspection, testing, packaging, shipping, installation, and maintenance of radiation shielding window components. These window components include wall liner embedments, dry lead glass radiation shielding window assemblies, oil-filled lead glass radiation shielding window assemblies, shielding wall plugs, barrier shields, view ports, and the installation/extraction table/device required for the installation and removal of the window components.1.2 Applicability: 1.2.1 This standard is intended for those persons who are tasked with the planning, design, procurement, fabrication, installation, and operation of the radiation shielding window components that may be used in the operation of hot cells, high level caves, mini-cells, canyon facilities, and very high level radiation areas.1.2.2 This standard applies to radiation shielding window assemblies used in normal concrete walls, high-density concrete walls, steel walls and lead walls.1.2.3 The values stated in 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. Common nomenclature for specifying some terms; specifically shielding, uses a combination of metric units and inch-pound units.1.2.4 This standard identifies the special information required by the Manufacturer for the design of window components. Table A1.1 shows a sample list of the radiation source spectra and geometry information, typically required for shielding analysis. Table A2.1 shows a detailed sample list of specific data typically required to determine the physical size, glass types, and viewing characteristics of the shielding window, or view port. Annex A3 shows general window configuration sketches. Blank copies of Table A1.2 and Table A2.1 are found in the respective Annexes for the Owner–Operator's use.1.2.5 This standard is intended to be generic and to apply to a wide range of configurations and types of lead glass radiation shielding window components used in hot cells. It does not address glovebox, water, X-ray glass, or zinc bromide windows.1.2.6 Supplementary information on viewing systems in hot cells may be found in Guides C1533 and C1661.1.3 Caveats: 1.3.1 Consideration shall be given when preparing the shielding window designs for the safety related issues discussed in the Hazard Sources and Failure Modes, Section 11; such as dielectric discharge, over-pressurization, radiation exposure, contamination, and overturning of the installation/extraction table/device.1.3.2 In many cases, the use of the word “shall” has been purposely used in lieu of “should” to stress the importance of the statements that have been made in this standard.1.3.3 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 requirements 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.

4.1 Many materials from which containers and packages are made, especially cellulosic materials, undergo changes in physical properties as the temperature and the relative humidity (RH) to which they are exposed are varied. Therefore, the package should be placed and kept in a specified atmosphere for a length of time such that subsequent measurements of physical properties will be meaningful and reproducible.4.2 The conditions described in this practice are either historically accepted standard conditions or special laboratory conditions chosen to represent particular phases of the distribution environment. These special conditions do not necessarily duplicate actual field conditions, but tend to simulate them and have effects on packages and materials which may be related to their field performance.1.1 This practice provides for standard and special conditioning and testing atmospheres that may be used to simulate particular field conditions that a container, package, or packaging component may encounter during its life or testing cycle.1.2 This practice describes procedures for conditioning these containers, packages, or packaging components so that they approach or reach equilibrium with the atmosphere to which they may be exposed. This standard is commonly used for conditioning when conducting transit simulation tests.1.3 Practice D685 should be used as the relevant conditioning standard when quantification of box compression strength at standard atmosphere conditions is required.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.
