Description / Abstract:
This test method covers the estimation of the steadystate rate
of transmission of a gas through plastics in the form of film,
sheeting, laminates, and plastic-coated papers or fabrics. This
test method provides for the determination of (1) gas
transmission rate (GTR), (2) permeance, and, in the case
of homogeneous materials, (3) permeability.
Two procedures are provided:
Procedure M—Manometric.
Procedure V—Volumetric.
The values stated in SI units are to be regarded as standard. No
other units of measurement are included in this standard.
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.
