GOST 22900-78 PDF

Full title and description

ГОСТ 22900-78 — Кожа искусственная и пленочные материалы. Методы определения паропроницаемости и влагопоглощения. (English title: Artificial leather and films. Methods for determination of water vapour permeability and moisture absorption). The standard specifies test procedures used to measure how much water vapour passes through artificial/synthetic leathers and polymer film materials and how much moisture these materials absorb under specified conditions.

Abstract

GOST 22900-78 sets out laboratory methods (primarily gravimetric/cup-type procedures) for determining water-vapour permeability (паропроницаемость) and moisture absorption (влагопоглощение) of artificial and synthetic leathers and household polymer film materials. It defines sample preparation, test apparatus and mounting, environmental conditioning, measurement procedure and calculation of results. The text includes later integrated amendments and references to related normative documents needed to perform the tests reliably.

Scope

The standard applies to artificial and synthetic leathers and to polymer film materials intended for household and similar uses. It establishes laboratory methods for determining the rate of water-vapour transmission through a material and the material's moisture absorption under specified test conditions. It is intended for quality control, specification verification and comparative testing of such materials.

Key topics and requirements

• Definitions and terms related to vapour permeability and moisture absorption for artificial leathers and polymer films.
• Requirements for specimen preparation, mounting and orientation (face/backsides) prior to testing.
• Gravimetric (cup) test procedure to determine amount of water vapour passing through a unit area per unit time (paropronitsaemost').
• Procedures for measuring moisture absorption (mass change after exposure/conditioning) and calculation formulas.
• Environmental conditioning and test atmosphere requirements, plus specification of reagents and measuring instruments needed.
• Instructions for reporting results, rounding, and handling of multiple measurements (repeatability/averaging).
• Integrated amendments that extend or clarify periods of validity and specific procedural details (Amendments 1–3).

Typical use and users

Manufacturers of artificial and synthetic leathers, producers of polymer film materials, independent testing and certification laboratories, quality assurance departments in footwear, upholstery and textile-related industries, research institutes in materials and polymer testing, and procurement/specification teams use this standard to verify product conformity, compare materials and support product technical documentation.

Related standards

Referenced and related normative documents commonly used with GOST 22900-78 include earlier standards replaced in part (e.g., ГОСТ 8951‑59 / ГОСТ 8971‑59 in their relevant sections), and normative references such as ГОСТ 427‑75, ГОСТ 667‑73, ГОСТ 4204‑77, ГОСТ 6709‑72, ГОСТ 8709‑72, ГОСТ 18481‑81 and ГОСТ 29062‑91. Internationally comparable procedures for water-vapour transmission and moisture tests (various ISO methods) are often consulted when aligning test programs across markets.

FAQ

Q: What is this standard?

A: ГОСТ 22900-78 is a Soviet / interstate standard titled "Кожа искусственная и пленочные материалы. Методы определения паропроницаемости и влагопоглощения" (Artificial leather and films — Methods for determination of water vapour permeability and moisture absorption) that specifies laboratory test methods for these properties.

Q: What does it cover?

A: It covers specimen preparation, test apparatus and mounting, environmental conditioning, gravimetric measurement procedures (cup-type method) and calculations to determine water-vapour permeability and moisture absorption of artificial/synthetic leathers and household polymer film materials.

Q: Who typically uses it?

A: Material manufacturers, footwear and upholstery producers, independent testing and certification laboratories, research institutes, and quality/control teams in industries that specify or verify performance of artificial leathers and polymer films.

Q: Is it current or superseded?

A: The standard was adopted in 1978 and came into force on 01 January 1979. Its text includes Amendments №1 (effective 01.01.1984), №2 (effective 01.01.1990) and №3 (effective 01.01.1997). Public databases list GOST 22900-78 as an active (действует) standard with the integrated amendments and with reissue/republishing in December 1997. Users should verify national applicability and any more recent national or EAEU technical regulations for market-specific conformity requirements.

Q: Is it part of a series?

A: It belongs to the leather/textile standards area (ICS/ОКС 59.140.30) and is associated with a family of GOST documents for leather, artificial leather and coated fabrics (other related GOSTs include methods for water permeability, hygroscopicity and conditioning standards). It replaces in part earlier standards on similar measurements.

Q: What are the key keywords?

A: Artificial leather, synthetic leather, polymer film, water vapour permeability, moisture absorption, cup method, gravimetric test, conditioning, ГОСТ 22900-78.
