Full title and description

ISO 139:2005/Amd 1:2011 — Textiles — Standard atmospheres for conditioning and testing. This is Amendment 1 (2011) to ISO 139:2005 (Edition 2) and updates/clarifies requirements for the standard and alternative atmospheres used when conditioning textile specimens and carrying out physical and mechanical tests.

Abstract

ISO 139:2005 defines the characteristics and use of a standard atmosphere for conditioning textile specimens prior to testing, and specifies a standard alternative atmosphere that may be used where agreed between parties. Amendment 1 (2011) provides editorial and technical changes to complement the 2005 edition.

Scope

Defines the characteristics, tolerances and use of a standard atmosphere for conditioning textiles before testing, and specifies a standard alternative atmosphere that may be used when agreed between the parties. It covers measurement and control requirements for temperature and relative humidity during conditioning and testing. Amendment 1 (2011) applies to the 2005 edition.

Key topics and requirements

• Standard atmosphere for conditioning: 20.0 °C ± 2.0 °C and 65.0 % ± 4.0 % relative humidity (typical temperate-zone condition used for most textile tests).
• Standard alternative atmosphere: 23.0 °C ± 2.0 °C and 50.0 % ± 4.0 % relative humidity (may be used only if agreed between parties).
• Tolerances and control: temperature and RH tolerances, measurement resolution and uncertainty requirements for instrumentation (measurement resolution typically 0.1 °C and 0.1 % RH; uncertainties generally specified to ensure reproducibility).
• Conditioning practice: specimen equilibration rules (mass-change criteria or time-to-equilibrium guidance) and recommendations for continuous monitoring and record-keeping of atmosphere during conditioning/testing.
• National / regional variants: some national standards and technical committees recognise an additional "tropical" conditioning option (for example 27.0 °C, 65 % RH) or provide local guidance; use of such variants should be stated in test reports.

Typical use and users

Used by textile laboratories, test houses, manufacturers and conformity assessment bodies to ensure consistent conditioning prior to tensile, dimensional, physical and mechanical testing of textile materials and finished products. Test method authors and standards committees reference ISO 139 when specifying the atmosphere for their specific test methods.

Related standards

Frequently referenced by and related to many textile test methods (ISO and EN series) that require preconditioning, for example standards for tensile testing, abrasion, dimensional change, yarn and fabric property methods. National equivalents or adoptions appear as EN ISO 139:2005/A1:2011 and in various national standards bodies' catalogues.

FAQ

Q: What is this standard?

A: ISO 139:2005 (with Amendment 1:2011) is the International Standard that specifies the standard and alternative laboratory atmospheres used to condition textile test specimens before physical and mechanical testing.

Q: What does it cover?

A: It covers the required temperature and relative humidity conditions (and their tolerances), measurement and control requirements for instrumentation, specimen equilibration guidance and reporting expectations for conditioning and testing of textiles.

Q: Who typically uses it?

A: Textile test laboratories, manufacturers, standards developers and conformity assessment bodies use ISO 139 to ensure consistent test atmospheres and reproducible test results across locations and over time.

Q: Is it current or superseded?

A: The 2005 edition (Edition 2) with Amendment 1 (2011) is published and, per ISO review records, the edition has been reviewed/confirmed as current in periodic ISO reviews (see ISO maintenance/lifecycle information). Users should check their national standards body or ISO for any later revisions.

Q: Is it part of a series?

A: ISO 139 is a stand‑alone International Standard addressing atmospheres for textile conditioning; it is commonly cited by numerous other ISO/EN textile test methods but is not itself divided into parts. Some national/adopted versions are published as EN ISO 139:2005/A1:2011.

Q: What are the key keywords?

A: Standard atmosphere; conditioning; temperature; relative humidity; textile testing; equilibration; ISO 139; amendment 2011.
