4.1 Much of the cushioned resilient flooring in use today is in household kitchens. Kitchen flooring is frequently subjected to the hazard of dropped tableware and cutting knives, that can puncture the wear layer of cushioned resilient flooring. Food and soil that become embedded in these punctures often can not be removed by ordinary maintenance, resulting in unsightly marks. Moisture, grease, or oils that penetrate to the cushion layer can be wicked into the foam and cause permanent discoloration. Ultimately, the service life of the material is shortened.1.1 This test method covers the laboratory procedure for determining the resistance of cushioned resilient floor coverings to punctures from dropped pointed objects such as dinner forks.1.2 This test method employs a 35-g cylindrical dart with a flat, small-diameter tip that is dropped onto a specimen of flooring. The dart represents the weight of a typical fork and the tip produces a similar puncture to those which result from dropped forks.1.3 Flooring with thick wear layers may not puncture under even the most severe drop. Although data can be obtained by increasing the drop height or the weight of the dart, values of this magnitude have no practical application.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. For specific precaution statement see 8.2.1.6 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.

5.1 Puncture using a 50 mm probe is applicable to determine the index strength resistance and deformation of a particular geotextile or geotextile-related products.5.2 This test method is considered satisfactory for acceptance testing of commercial shipments of geotextiles.5.3 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of the type in question. The test specimens then should be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future test results in light of the known bias.5.4 This test method is not applicable to materials that are manufactured in sizes that are too small to be placed into the test apparatus in accordance with the procedures in this test method. Furthermore, it is not appropriate to separate plies of a geosynthetic or geocomposite for use in this test method.1.1 This test method is an index test used to measure the force required to puncture a geotextile and geotextile-related products with a 50 mm diameter cylindrical probe. The dimensions of the probe provide a multidirectional force on the geotextile.NOTE 1: This test is also commonly known as CBR Puncture Test.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.

4.1 Puncture resistance is very important in end-use performance of stretch wrap film used in consumer and industrial product applications. Puncture resistance is a measure of the energy-absorbing ability of a stretch wrap film in resisting a protrusion. The test method is designed to provide the user with a means of measuring the stretch wrap film's puncture resistance performance under essentially biaxial deformation conditions. A biaxial stress is representative of the type of stress encountered by stretch wrap products in many end-use applications.4.2 Although this test method cannot be expected to duplicate all field experiences, since the rate of speed, weight, and configuration of such destructive forces vary widely, a generally reliable comparison of samples may be made from the data obtained.1.1 This test method determines the resistance of a stretch wrap film to the penetration of a probe at a standard low rate, a single test velocity. Performed at standard conditions, the test method imparts a biaxial stress that is representative of the type of stress encountered in many product end-use applications. The maximum force, force at break, penetration distance, and energy to break are determined.1.2 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.1.3 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 pyramid method of puncture resistance is an index test for the determination of the puncture resistance of unprotected geomembranes or geomembranes protected with nonwoven geotextiles and other puncture-protective geosynthetics.5.1.1 The purpose of this test method is to establish an index value of puncture resistance by providing standard criteria and a basis for uniform reporting.5.2 This test method may be used for acceptance testing of commercial shipments of geomembranes and geomembranes protected with nonwoven geotextiles; however, caution is advised since information about between-laboratory precision is incomplete.1.1 The test method is to be used as an index test to determine the pyramid puncture resistance of geomembranes and, or both, geomembranes protected by nonwoven geotextiles and other puncture-protective geosynthetics.1.2 The test method measures the increase of the pyramid puncture resistance due to the use of protective nonwoven geotextiles with geomembranes.1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.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 Procedure A—This procedure is an index-type test which can be used as a guide for acceptance of commercial shipments of geosynthetics. The standard cone and pyramid test fixtures can establish critical height (ch) consistency with similar material from previous lots or different suppliers, as well as testing from other laboratories. However, due to the time required to perform tests, it is generally not recommended for routine acceptance testing.4.2 Procedures B and C—These procedures are performance tests intended as a design aid used to simulate the in-situ behavior of geosynthetics under hydrostatic compression. These test methods may assist a design engineer in comparing the ability of several candidate geosynthetic materials to conform to a site-specific subgrade under specified use and conditions. In procedure B, the pressure is increased until a failure is observed. In procedure C, a given set of conditions (pressure, temperature and test duration) are maintained constant and the performance of the system is observed at the end of the test.1.1 This test method evaluates the stress/time properties of geosynthetics by using hydrostatic pressure to compress the geosynthetic over synthetic or natural test bases consisting of manufactured test pyramids/cones, rocks, soil, or voids.1.2 This test method allows the user to determine the relative failure mode or points of failure for geosynthetics, or both.1.3 This test method offers two distinct procedures:1.3.1 Procedure A incorporates manufactured test pyramids or cones as the base of the testing apparatus. Procedure A is intended to create comparable data between laboratories, and can be used as a guide for routine acceptance tests for various materials.1.3.2 Procedures B and C incorporate site-specific soil or other material selected by the user as the test base of the testing apparatus. Procedures B and C are methods for geosynthetic design for a specific site.1.4 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 non-conformance with the 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. For a specific warning statement, see Section 6.1.6 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.

4.1 The puncture-propagation of tear test measures the resistance of a material to snagging, or more precisely, to dynamic puncture and propagation of that puncture resulting in a tear. Failures due to snagging occur in a variety of end uses, including industrial bags, liners, and tarpaulins. The units reported in this test method are Newtons (tear resistance).4.2 Experience has shown that for many materials puncture does not contribute significantly to the force value determined, due to the sharpness of the propagating probe used. However, comparing the results of prepunctured test specimens with normal nonpunctured specimens will give an indication of the extent of any puncture resistance in the reported result.4.3 For many materials, there may be a specification that requires 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 current ASTM materials standards.1.1 This test method covers the determination of the dynamic tear resistance of plastic film and thin sheeting subjected to end-use snagging-type hazards.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.NOTE 1: Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.).NOTE 2: There is no known ISO equivalent to this standard.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 An important factor affecting the performance of many membrane roofing systems is their ability to resist static puncture loads. This test method provides a means for assessing static puncture resistance.5.2 This test method can be used to compare the puncture resistance of a single type of membrane as a function of a variety of insulation substrates or, conversely, to compare the resistance of a number of membrane specimens set on a single type of insulation.5.3 The effect of temperature on puncture resistance can be studied by conducting the test under controlled conditions using such equipment as an environmental chamber, oven, or freezer.5.4 This test method can be useful for developing performance criteria for membrane roofing systems.5.5 This test method can be useful for developing classifications of the static puncture resistance of membrane roofing systems.5.6 While it is considered that the results obtained by this laboratory test can afford a measure of the static puncture resistance of membrane roofing systems in the field provided that service loads and temperature conditions are known, no direct correlation has yet been established.5.7 This test method can be useful for evaluating the static puncture resistance of membranes used in vegetative roof systems.1.1 This test method covers evaluation of the maximum static puncture load that roofing membrane specimens can withstand without allowing the passage of water.1.2 This laboratory test is conducted at any desired temperature using sheet membrane specimens manufactured in a factory or prepared in a laboratory.1.3 Roof membrane specimens to which the test method is applicable include bituminous built-up, polymer-modified bitumens, vulcanized rubbers, non-vulcanized polymeric, and thermoplastic materials.1.3.1 The applicability of this test method to these membrane specimens includes their use in vegetative roof systems.1.4 This test method is not applicable to aggregate-surfaced membrane specimens, but it is applicable to specimens having factory-applied granules.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 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.1.6 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.

4.1 This test method is designed to provide load versus deformation response of plastic films under essentially multi-axial deformation conditions at impact velocities. This test method further provides a measure of the rate sensitivity of the plastic films to impact.4.2 Multi-axial impact response, while partly dependent on thickness, does not necessarily have a linear correlation with specimen thickness. Therefore, results should be compared only for specimens of essentially the same thickness, unless specific responses versus thickness formulae have been established for the plastic films being tested.4.3 For many plastic films, it is possible that a specification exists that requires 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.4.4 The values obtained by this test method are highly dependent on the method and conditions of film fabrication as well as the type and grade of resin. Results can vary significantly, depending upon sample quality, uniformity of film gage, die marks, contaminants, and so forth.1.1 This test method covers the determination of puncture properties of plastic films, over a range of test velocities.1.1.1 ASTM Terminology Standard D883 has defined film as having a thickness not greater than 0.25 mm. Plastic materials having a thickness above this limit are not to be excluded from use unless shown to be rigid (see 3.2.1). Test Method D3763 is the recommended method for instrumented puncture testing of rigid plastics.1.2 Test data obtained by this test method is relevant and appropriate for use in engineering design.1.3 The values stated in SI units are to be regarded as standard.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.NOTE 1: This test method does not closely conform to ISO 7765-2. The only similarity between the two tests is that they are both instrumented impact tests. The differences in striker, fixture, specimen geometries and in test velocity can produce significantly different test results.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.

This specification provides the performance requirements and associated test procedures for the puncture resistance of materials used in the construction of containers for discarded medical needles and other sharps. It shall establish the average and minimum value of puncture force that the container materials must withstand under controlled laboratory conditions and normal room temperature when following the test procedure described herein. Materials meeting the specified performance requirements will be considered puncture resistant, but this specification will not evaluate the construction of, or provide pass/fail criteria for, sharps containers.1.1 The purpose of this specification is to provide a test procedure and performance requirement for the puncture resistance of materials used in the construction of containers for discarded medical needles and other sharps. This test specification will establish (1) the average puncture force and (2) a minimum value of puncture force that container material(s) must withstand when following the test procedure described in Section 6. This specification shall be applicable to regions of uniform material and thickness, and needle contact areas as defined in 3.1.7 and 3.1.9. Materials meeting the performance requirements of Section 4 shall be considered “puncture-resistant.” This specification does not evaluate the construction of, or provide pass/fail criteria for, a sharps container.1.2 This specification provides a test procedure to determine if all regions of one container meet the material puncture resistance requirements. It does not define the number of additional test containers required to achieve a statistically valid sample of a manufacturing lot or process. An appropriate sampling plan shall be determined by the test requester, as this depends upon the manufacturing process variability, manufacturing lot size, and other factors, such as end-user requirements.1.3 This specification is intended to evaluate the performance of materials used in the construction or manufacture of sharps containers under controlled laboratory conditions, and at normal room temperature (see 6.1). (Warning—This specification only characterizes material puncture resistance at normal room temperatures. Applications of sharps containers outside the range of 23 ± 2°C (such as usage in emergency vehicles) require further material characterization by the product specifier to determine suitable use.)1.4 The values stated in inch/pound are to be regarded as the standard. The SI values given in parentheses are for information only.1.5 The following hazard caveat pertains only to the test procedure portion, Section 6, of this specification.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 and health practices and determine the applicability of regulatory limitations prior to use.
