5.1 This test method is used by athletic footwear manufacturers and others, both as a tool for development of athletic shoe cushioning systems and as a test of the general cushioning characteristics of athletic footwear products, materials and components. Adherence to the requirements and recommendations of this test method will provide repeatable results that can be compared among laboratories.5.2 Data obtained by these procedures are indicative of the impact attenuation of athletic shoe cushioning systems under the specific conditions employed.5.3 This test method is designed to provide data on the force versus displacement response of athletic footwear cushioning systems under essentially uniaxial impact loads at rates that are similar to those of heel and forefoot impacts during different athletic activities.5.4 The peak or maximum values of force, acceleration, displacement, and strain are dependent on the total impact energy applied to the specimen. These values are normalized to provide comparative results for a reference value of total energy input.5.5 Impact attenuation outcomes are strongly dependent on initial conditions (impact mass, impact velocity, contact area, etc.) and on specimen size and the specimen’s prior history of compressive loading. Therefore results should be compared only for specimens of the same nominal size and prior conditioning.Note 1—Impact test outcomes have been found to correlate with in-vivo loads (peak ground reaction force, peak plantar pressure, lower extremity acceleration) experienced by runners. Relationships between test outcomes and subjective perceptions of cushioning have also been found. However, there is no direct evidence of a correlation between scores on this test method and the probability of injury among users of a particular athletic footwear product.1.1 This test method describes the use of a gravity-driven impact test to measure certain impact attenuation characteristics of cushioning systems and cushioning materials employed in the soles of athletic shoes.1.2 This test method uses an 8.5 kg mass dropped from a height of 30-70 mm to generate force-time profiles that are comparable to those observed during heel and forefoot impacts during walking, running and jump landings.1.3 This test method is intended for use on the heel and or forefoot regions of whole, intact athletic shoe cushioning systems. An athletic shoe cushioning system is defined as all of the layers of material between the wearer's foot and the ground surface that are normally considered a part of the shoe. This may include any of the following components: outsole or other abrasion resistant outer layer, a midsole of compliant cushioning materials or structures forming an intermediate layer, an insole, insole board, or other material layers overlying the midsole, parts of the upper and heel counter reinforcement which extend beneath the foot, and an insock, sockliner or other cushioning layers, either fixed or removable, inside the shoe.1.4 This test method may also be employed in to measure the impact attenuation of cushioning system components and cushioning material specimens.1.5 This test method is not intended for use as a test of shoes classified by the manufacturer as children's shoes.1.6 The type, size or dimensions and thickness of the specimen, the total energy input and prior conditioning shall qualify test results obtained by this test method.1.6.1 The range of tests results is limited by the calibrated range of the test device’s force transducer. Combinations of thin specimens, high specimen stiffness and high total energy input may produce forces that exceed the transducer’s capacity and are hence not measurable. In practice, the specified force transducer range (10 kN) accommodates more than 99 % of typical shoe soles and cushioning material specimens that are 7 mm or more in thickness at a total energy input of 5 Joules.1.6.2 The nominal value of the total energy input applied by this test method is 5 J for shoes, such as running shoes, which are subject to moderate impacts during normal use. Total energy inputs of 7.0 J and 3.0 J may be used for shoes (e.g basketball shoes) which are subject to higher impact loads during normal use. Other values of total energy input may be used, if they are stated in the report.1.6.3 Results from tests performed with different total energy inputs or with different masses are not directly comparable.1.6.4 Specimen thickness has a significant effect on impact attenuation outcomes. Consequently, results from tests of material specimens of different thicknesses cannot be directly compared.1.6.5 The impact attenuation of cushioning materials may change over time and with use (e.g. wear or durability testing) or prior conditioning (e.g. from previous tests). Consequently, test results obtained using this test method shall be qualified by the age and prior conditioning of the samples.1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.8 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 the measurement of the interzone attenuation of furniture panels used as acoustical barriers in open-plan spaces to provide speech privacy or sound isolation between working positions.1.2 This test procedure was originally developed using the foot-pound system of units for prescribing measurement positions and distances. However, the use of SI units is preferred by ASTM. For this reason, dimensions are provided in SI units, with approximate foot-pound conversions indicated.1.2.1 Unless otherwise qualified, all dimensions specified in this test method shall be understood to have a tolerance of ± 25 mm (± 1 in.), even though the indicated approximate conversions of the numerical dimensions given will not always be accurate to this extent. All measurements shall be made in SI units or the corresponding exact foot-pound units.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 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 .

1.1 This laboratory test method measures the degree to which reflected sound is attenuated by the most commonly found vertical surfaces in open-plan spaces. Reflection of sound from vertical surfaces is a concern in open-plan spaces because it can reduce speech privacy. The vertical surfaces covered by this test method include wall finishes such as sound-absorbent panels, and furniture panels or screens. It does not cover such items as window finishes or furniture other than panels.1.2 This test procedure was originally developed using the foot-pound system of units for prescribing measurement positions and distances. However, the use of SI units is preferred by ASTM. For this reason, dimensions are provided in SI units, with approximate foot-pound conversions indicated in parentheses.1.2.1 Unless otherwise qualified, all dimensions specified in this test method shall be understood to have a tolerance of ± 25 mm (± 1 in.), even though the indicated approximate conversion of the numerical dimensions given will not always be accurate to this extent. All measurements shall be made in SI units or the corresponding exact foot-pound units.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 and health practices and determine the applicability of regulatory limitations prior to use.
