Full title and description

St ISO 5636-6-2015 — Paper and board — Determination of air permeance (medium range) — Part 6: Oken method. This international standard specifies the Oken method (Oken tester) for determining air permeance and air resistance of paper and board in the medium range; it is intended for use where samples can be securely clamped to avoid leakage.

Abstract

ISO 5636-6:2015 defines the principle, apparatus, sampling, conditioning, calibration, test procedure, calculation and reporting of results for measuring air permeance (and corresponding air resistance) of papers and boards using the Oken method. The method has no intrinsic limitation on measuring range but is unsuitable for rough‑surfaced materials that cannot be clamped to prevent leakage.

Scope

Specifies the Oken method (Oken air‑resistance tester) to determine air permeance and air resistance of papers and boards in the medium permeance range. The method covers apparatus requirements, specimen preparation, conditioning, calibration, test procedure, result calculation and reporting, and includes informative annexes on measurement principle and precision data. It is not suitable for materials with rough surfaces that cannot be clamped to prevent leakage.

Key topics and requirements

• Principle of the Oken method and relation to other air‑permeance measurements (Gurley/Bendtsen).
• Apparatus descriptions: Oken (air‑resistance) tester and acceptable sensor/measurement types.
• Sampling, specimen preparation and conditioning (standard laboratory conditions prior to testing).
• Calibration procedures and routine checks of the tester.
• Test procedure, calculation of air permeance (and air resistance) and statistical treatment (standard deviation, coefficient of variation).
• Informative annexes providing measurement principle explanation and precision/ repeatability data.

Typical use and users

Used by paper and board manufacturers, quality control laboratories, printing and converting operations, material testing laboratories, and standards bodies to quantify air permeance/air resistance for process control, specification compliance, R&D and comparative testing. Laboratories that compare results across methods may use it alongside other ISO 5636 parts.

Related standards

Part of the ISO 5636 series for air permeance and air resistance measurement. Related parts include ISO 5636‑3 (Bendtsen method), ISO 5636‑4 (Sheffield method) and ISO 5636‑5 (Gurley method); older parts (e.g., Parts 1 and 2) have historical/withdrawn versions. These parts define alternative measurement techniques and ranges used for different specimen types and permeance ranges.
