Full title and description

Materials used as cigarette papers, filter plug wrap and filter joining paper, including materials having a discrete or oriented permeable zone and materials with bands of differing permeability — Determination of air permeability. This international standard specifies a laboratory method to determine the air permeability (air flow under a defined pressure difference) of papers and wraps used in cigarette and filter construction, including banded and zoned products.

Abstract

The standard defines a test procedure to measure air permeability (AP) of materials used as cigarette papers, filter plug wrap and filter joining paper. It applies to materials with oriented or discrete permeable zones where measured permeability exceeds 10 cm3·(min−1·cm−2) at 1 kPa and to banded cigarette papers having bands at least 4 mm wide. The method uses a clamped specimen, a controlled pressure difference across the specimen and measurement of the resulting volumetric air flow.

Scope

Specifies a laboratory method for the determination of air permeability of cigarette paper, filter plug wrap and filter joining paper. The procedure is applicable to homogeneous materials and to materials with discrete or oriented permeable zones when measured permeability is greater than 10 cm3·(min−1·cm−2) at 1 kPa; it is also applicable to banded cigarette papers where band width is ≥ 4 mm. Notes in the standard identify how to estimate permeability for materials outside the strict scope.

Key topics and requirements

• Definition of test specimen preparation and mounting (clamping and sealing requirements).
• Generation and control of a specified pressure difference across the specimen (typically 1 kPa reference conditions).
• Measurement of volumetric air flow through the specimen and calculation of air permeability (units and formulas specified).
• Applicability rules for zoned and banded materials, including threshold permeability (10 cm3·(min−1·cm−2)) and minimum band width (≥ 4 mm).
• Requirements for test equipment calibration, environmental conditions and reporting of results (repeatability/reproducibility considerations).

These items and procedural details are given in the body of ISO 2965:2019.

Typical use and users

Used by tobacco product manufacturers, paper and wrapping material producers, independent testing and quality laboratories, conformity assessment bodies, and regulatory laboratories for product development, quality control, supplier verification and regulatory compliance testing of cigarette papers and filter wraps. Test-house personnel and instrumentation engineers implementing air-permeability rigs also rely on this method.

Related standards

Relevant ISO standards commonly referenced alongside ISO 2965:2019 include ISO 3308 (routine analytical cigarette‑smoking machine — definitions and standard conditions), ISO 8243 (cigarettes — sampling), and other tobacco testing standards that cover smoke constituent measurement and sampling procedures. The previous edition ISO 2965:2009 is listed as withdrawn and superseded by the 2019 edition.

FAQ

Q: What is this standard?

A: ISO 2965:2019 is an international standard that specifies a laboratory method to determine the air permeability of materials used as cigarette papers, filter plug wrap and filter joining paper.

Q: What does it cover?

A: It covers specimen preparation, apparatus and measurement procedures to obtain air permeability values (including units and calculation), with specific applicability rules for zoned and banded materials (threshold of 10 cm3·(min−1·cm−2) at 1 kPa and band widths ≥ 4 mm).

Q: Who typically uses it?

A: Tobacco manufacturers, material suppliers, independent testing laboratories, regulators and conformity assessment bodies use this standard for product development, quality control and regulatory testing.

Q: Is it current or superseded?

A: ISO 2965:2019 is the current edition (4th edition). The publication was systematically reviewed and confirmed in 2024, so the 2019 edition remains current; it supersedes ISO 2965:2009.

Q: Is it part of a series?

A: It is part of the body of ISO standards addressing tobacco and tobacco-product testing (ISO/TC 126 work), and is commonly used together with other tobacco testing standards such as ISO 3308 and ISO 8243 for broader testing and sampling workflows.
