ASTM C147-86(2000) - 1.1.2000
 
1. Scope

1.1 These test methods cover the determination of the breaking strength of glass containers when subjected to internal pressure. These test methods are intended to determine the pressure strength of containers manufactured to contain products reasonably expected to develop a sustained pressure of 138 kPa (20 psi) or greater, after processing. Two test methods are covered as follows:

Sections
Test Method A-Application of Uniform Internal Pressure for a Predetermined Period5-7
Test Method B-Application of Internal Pressure Increasing at a Predetermined Constant Rate8-10

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 and health practices and determine the applicability of regulatory limitations prior to use.

Standard Practice for Sampling Glass Containers

Single-head hydraulic testing machine (8 blueprints) Single-head automatic sustained pressure testing machine developed by American Glass Research, Inc., Butler, PA, meets these requirements for durations greater than 15 s. Detailed working drawings of this machine are available from ASTM Headquarters. An increment pressure tester developed by the same laboratory is suitable for shorter durations. Available from ASTM International Headquarters. Order Adjunct No. .
