Description

ASTM D4279-95-Reapproved2009

Historical Standard: Standard Test Methods for Water Vapor Transmission of Shipping Containers-Constant and Cycle Methods

ASTM D4279

Scope

1.1 These test methods cover the determination of water vapor transmission rates for bulk shipping containers, as follows:

1.1.1 Method A, for Reclosable Containers, and

1.1.2 Method B, for Containers Not Designed for Reclosing.

1.2 Within each procedure details are given for the constant and cycle methods of test atmosphere.

1.3 The test may be applied to the container as packed, or after one or more performance tests such as drum (Method D 782), vibration (Methods D 999), drop (Test Method D 5276), impact resistance (Test Methods D 880, D 4003, and D 5277), or performance tests (Practice D 4169), as required.

1.4 For small shipping containers requiring greater accuracy in weighing, the water vapor transmission may be determined in accordance with Test Method D 895 or Test Method D 1251.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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.
