Описание (английский):

ISO 15105-2:2003 specifies a method for the determination of the gas-transmission rate of any plastic material in the form of film, sheeting, laminate, co-extruded material or flexible plastic-coated material. Specific examples, currently in use, of the method are described in the annexes.

Overview

ISO 15105-2:2003 - "Plastics - Film and sheeting - Determination of gas‑transmission rate - Part 2: Equal‑pressure method" specifies an equal‑pressure, isobaric test for measuring the gas‑transmission rate (GTR) of plastic films, sheetings, laminates, co‑extruded and flexible plastic‑coated materials. The method measures permeation driven by a partial‑pressure difference while keeping total pressure equal on both sides of a test specimen. Annexes give practical implementations, including oxygen measurement using a coulometric sensor and detection by gas chromatography.

Key topics and requirements

Scope: Applies to any plastic material in film or sheet form, including laminates and coated materials.

Test principle: Two‑chamber transmission cell; one chamber supplied with test gas, the other swept with carrier gas. Identical total pressure in both chambers; permeation occurs due to partial‑pressure difference.

Specimen preparation:

Representative, defect‑free specimens larger than the permeation area.
Thickness measured per ISO 4593 at ≥5 points; report min/max/average.
Typically use three specimens unless otherwise agreed.

Conditioning and temperature:

Drying or humidity conditioning as appropriate (e.g., 48 h drying or conditioned at specified RH).
Default test temperature 23 °C ± 2 °C unless otherwise specified.
Tabled sets of diffusion conditions include several RH options (0 %, 50 %, 60 %, 75 %, 85 % at 23 °C; also 10 °C/85 %).

Apparatus and operation:

Transmission cell with laminar flow on both sides; effective permeation area typically between 1 cm² and 150 cm².
Carrier and test gas flow rates generally 5–100 ml/min; purge and stabilization required prior to measurement.
Gasket materials must have negligible permeation relative to the specimen.

Detection methods:

Annex A: Coulometric sensor (recommended for oxygen‑transmission rate, OTR).
Annex B: Gas chromatography (for other gases/mixtures).

Reporting and precision:

Results and test report formats given in annexes. Precision not specified (no interlaboratory data available at time of publication).

Applications and practical value

Measurement of oxygen‑transmission rate (OTR) and other gas permeabilities for:

Food and beverage packaging (shelf‑life and barrier quality).
Pharmaceutical packaging (blister packs, foil laminates).
Industrial barrier films (chemical or moisture protection).
R&D, quality control, supplier qualification and comparative testing.

Useful for materials selection, barrier optimization, and regulatory compliance where quantified gas‑barrier performance is required.
