Meaning and Purpose
5.1 This test method provides a structured procedure to determine the hazard level of glass, glass systems and glass retrofit systems subjected to air explosion loads. Knowing the hazard level allows assessing the risk of personal injury and damage to facilities.

5.2 glass or glass material level does not mean that the danger of a single sample can resist its rating of 1.0 specific air blast. The probability that an individual glass or glass building specimen resists its rated specific air explosion increases in proportion to the number of specimens that successfully resist a given air explosion level up to its rated hazard level.

ASTM F1642-2017 Standard Test Method for Door and Window Glass and Glass Assembly Systems Under Air Flow Load

Scope of
1.1 This test method specifies procedures for assessing the hazard of glass or glass systems to air explosive loads. The designated organization shall provide the air explosion load parameters. The glass system shall be as defined in Specification F2912.

1.2 from the method of the data obtained from the test is applied to use standard F2912 sure glass or glass, glass system transformation system risk level.

1.3 this test method allows with or without a frame system of glass for testing and rating.

1.4 the test method is designed to test and evaluation system of all glass, glass and glass systems, including but not limited to, made of glass, plastic, plastic cladding glass, sandwich glass, glass/plastic materials, organic coating glass and other are not directly connected to the glass or glass glass transformation system, such as explosion-proof, cable grid, shadows, and architecture.

1.5 Units-Values expressed in SI units or inch-pound units should be treated separately as standard values. The values specified in each system may not be exactly equivalent; Therefore, each system should be used independently of each other. Merging values from both systems may result in non-compliance with the criteria. For the conversion of quantities in various measurement systems to SI units, see specification E699.

1.6 This standard is not intended to address all safety issues, if any, associated with its use. The user of this international standard has the responsibility to establish appropriate safety and health practices, and determine regulations limit the applicability of before use. See Section 7 for a description of specific hazards.
