Full title and description

St ISO 15105-1-2007 — Plastics — Film and sheeting — Determination of gas-transmission rate — Part 1: Differential-pressure methods. This international standard specifies differential-pressure (manometric) methods for measuring the gas transmission rate (GTR) of single-layer and multi-layer plastic films and sheet materials, using either a pressure sensor or a gas chromatograph to quantify permeating gas.

Abstract

ISO 15105-1:2007 defines two differential-pressure methods to determine the rate at which gases permeate through plastic film and sheeting. The standard describes specimen mounting between two chambers (both evacuated then one filled with the test gas), measurement principles (manometric pressure rise or chromatographic detection), units and normalization (e.g., cm3(STP)/m2·day or mol/m2·s·Pa), and typical test conditions used for characterization of barrier performance. The standard is aimed at repeatable laboratory measurement of gas transmission for material development, quality control and specification.

Scope

Specifies two differential-pressure methods for determining gas-transmission rates of single-layer plastic film or sheet and multi-layer structures: a manometric (pressure-rise) technique using a pressure sensor and a method using a gas chromatograph to measure the gas that permeates into the low-pressure chamber. It covers specimen preparation and mounting, test-cell operation (evacuation and controlled filling), calculation of transmission/permeability values and reporting of results for common gases used in barrier testing. The standard is intended for laboratory measurement rather than in-field container testing.

Key topics and requirements

• Measurement principles: differential-pressure (manometric) pressure-rise method and chromatographic detection method for permeating gas.
• Specimen mounting and test-cell configuration: two-chamber arrangement with evacuation and controlled filling of the upstream chamber.
• Calculation and units: gas transmission rate (GTR) reported in common units (e.g., cm3(STP)/m2·day) and permeability normalized to thickness when required.
• Applicable gases: oxygen, carbon dioxide, nitrogen, air and other test gases as appropriate for material/application.
• Typical test conditions and limits: standard laboratory temperatures (e.g., around 23 °C ±2 °C) and ambient pressure differentials; detection limits depend on instrumentation and cell design.
• Reporting: detailed test conditions, instrumentation used (pressure sensor or GC), specimen thickness, orientation and any preconditioning.

Typical use and users

This standard is used by materials scientists, packaging development teams, quality-control and testing laboratories, converters and suppliers of films and laminates, and regulatory/acceptance testing bodies to quantify barrier performance of films and sheet materials for food packaging, medical packaging, industrial barrier applications and material selection. Laboratories offering permeability testing commonly reference ISO 15105-1 when reporting differential-pressure results.

Related standards

ISO 15105-1 is Part 1 of the ISO 15105 series; related documents include ISO 15105-2 (equal-pressure or equal-pressure/oxygen transmission rate methods) and other permeability standards and test methods such as ASTM D1434 (manometric methods) and older ISO/EN references for specific gases and containers. Earlier edition ISO 15105-1:2002 was withdrawn and replaced by the 2007 edition.
