1.1 These test methods cover the evaluation of the resistance of glass containers to chemical attack. Three test methods are presented, as follows: 1.1.1 Test Method B-A covers autoclave tests at 121°C on bottles partially filled with dilute acid as the attacking medium. 1.1.2 Test Method B-W covers autoclave tests at 121°C on bottles partially filled with distilled water as the attacking medium. 1.1.3 Test Method P-W covers autoclave tests at 121°C on powdered samples with pure water as the attacking medium. 1.2 The values stated in SI units are to be regarded as the standard. The values 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 and health practices and determine the applicability of regulatory limitations prior to use.
