ASTM D1434 測(cè)定塑料薄膜和薄片的透氣性的標(biāo)準(zhǔn)測(cè)試方法 –適用范圍
Scope：
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.
