ASTM F1642/F1642M-17

5.1 This test method provides a structured procedure to establish the hazard rating of glazing, glazing systems, and glazing retrofit systems subjected to an airblast loading. Knowing the hazard rating provides the ability to assess the risk of personal injury and facility damage.

5.2 The hazard rating for a glazing or glazing material does not imply that a single specimen will resist the specific airblast for which it is rated with a probability of 1.0. The probability that a single glazing or glazing construction specimen will resist the specific airblast for which it is rated increases proportionally with the number of test specimens that successfully resist the given level of airblast to the hazard level for which it is rated.

1.1 This test method sets forth procedures for the evaluation of hazards of glazing or glazing systems against airblast loadings. The specifying authority shall provide the airblast loading parameters. Glazing systems shall be as defined in Specification F2912.

1.2 The data obtained from testing under this method shall be used to determine the glazing, glazing system, or glazing retrofit system hazard rating using Specification F2912.

1.3 This test method allows for glazing to be tested and rated with or without framing systems.

1.4 This test method is designed to test and rate all glazing, glazing systems, and glazing retrofit systems including, but not limited to, those fabricated from glass, plastic, glass-clad plastics, laminated glass, glass/plastic glazing materials, organic coated glass, and other glazing retrofit systems not directly attached to the glazing or glazing system such as blast curtains, cables, shades, and architectural mesh.

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 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. For conversion of quantities in various systems of measurements to SI units, see Specification E699.

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. See Section 7 for specific hazards statements.
