ISO 5636-5 Air Permeability test Paper and board

ISO 5636-5 permeability test Paper and board — Determination of air permeance (medium range) Part 5: Gurley method

ISO 5636-5 specifies the Gurley method for determining the air permeance of paper and board using an air resistance tester, the Gurley apparatus.

It is applicable to papers and boards which have air permeances between 0,1 µm/(Pa⋅s) and 100 µm/(Pa⋅s) when tested with the Gurley apparatus. It is unsuitable for rough-surfaced materials, which cannot be securely clamped to avoid leakage.

ISO 15105-1 Gas transmission rate test of plastics Film by differential-pressure method

ISO 15105-1 Plastics — Film and Sheeting — Determination of Gas-transmission Rate — Part 1: Differential-pressure Methods

ISO 15105-1 defines two standardized differential-pressure test methods to quantify the gas barrier performance of plastic films, sheets and multi-layer plastic structures, focusing on measuring Gas Transmission Rate (GTR) and Gas Permeability Coefficient (P) under a controlled gas partial pressure difference across the specimen.

ISO 2556 Gas transmission rate GTR test of films and thin sheets

ISO 2556 Plastics — Determination of the gas transmission rate of films and thin sheets under atmospheric pressure — Manometric method

ISO 2556 defines a single mercury-based manometric differential-pressure test method to measure Gas Transmission Rate (GTR) of thin plastic films and sheets, with a measurable range of 1 to 20000 cm³/(m²·d·atm). It uses a mercury capillary manometer to quantify pressure rise in the evacuated low-pressure chamber under a fixed upstream atmospheric test gas pressure.

ASTM D1434 Gas Permeability Test of Plastic Film and Sheeting

ASTM D1434 Standard Test Method for Determining Gas Permeability Characteristics of Plastic Film and Sheeting

ASTM D1434 defines an electronic manometric differential-pressure method to measure three core barrier metrics: Gas Transmission Rate (GTR), permeance, and material permeability (only valid for homogeneous plastics). It covers plastic films, sheets, multi-layer laminates, plastic-coated paper and plastic-coated fabrics, and follows WTO TBT international standardization principles.
