ASTM D1434-82(2009)e1 Standard Test Method for Determining Gas Permeability Characteristics of Plastic Film and Sheeting

ASTM D1434-82(2009)e1 塑料薄膜和薄板的气体渗透特性的测定的标准试验方法

样品要求：A4大小, 3 pcs

周期：9~11个工作日

Scope：

1.1 This test method covers the estimation of the steady-state 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.

1.2 Two procedures are provided:

1.2.1 Procedure M—Manometric.

1.2.2 Procedure V—Volumetric.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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.
