Full title and description

St ISO 3801-1977 (1983) — International Standard ISO 3801:1977, "Textiles — Woven fabrics — Determination of mass per unit length and mass per unit area". The record shown here corresponds to the ISO first edition published in 1977; some national listings or reproductions/traductions are catalogued with the variant title "St ISO 3801-1977 (1983)".

Abstract

Specifies methods for determining (a) the mass per unit length and (b) the mass per unit area of woven fabrics (including "stretch" types). Procedures apply to fabrics presented full width or folded down the middle and cover measurements on complete pieces as well as on sample lengths; results are reported after conditioning the specimen in the standard atmosphere for testing.

Scope

Defines test procedures to determine fabric mass both as mass per unit length (useful for narrow or longitudinal measurements) and as mass per unit area (g/m2). The scope explicitly covers woven fabrics (including stretch types), fabrics supplied full width or folded, and both whole-piece and sample-length determinations under standard conditioning. The standard is intended for routine laboratory and production measurement of fabric weight characteristics.

Key topics and requirements

• Specimen conditioning in the standard atmosphere for testing before measurement.
• Definition and procedure for measuring mass per unit length (expressed in g/m or similar units).
• Definition and procedure for measuring mass per unit area (expressed in g/m² or similar units).
• Instructions for sampling full-width and folded fabrics and for handling selvages and seams.
• Required precision of balances and measuring devices and rounding/reporting rules for results.
• Applicability notes for special constructions (e.g., stretch fabrics) where width and structure affect the relation between linear and areal mass values.

Typical use and users

Used by textile test laboratories, quality control departments in fabric mills, product specification writers, procurement and inspection teams, and R&D groups developing and comparing woven-fabric constructions. It is a routine standard for verifying declared fabric weight (g/m²) and for production acceptance testing.

Related standards

Standards in the ISO textile series that are commonly used alongside ISO 3801 include test methods for thickness (ISO 5084), tensile and dimensional properties, conditioning and atmosphere for testing, and standards for sample preparation and identification. National adoptions or identical adoptions (e.g., NEN ISO 3801, STN ISO 3801) exist as country-specific implementations of the ISO text.

FAQ

Q: What is this standard?

A: ISO 3801:1977 is an international test method that specifies how to determine the mass per unit length and the mass per unit area of woven fabrics (first edition published 1 September 1977). Some national catalogues or translations list the ISO text under variant labels such as "St ISO 3801-1977 (1983)".

Q: What does it cover?

A: It covers sampling, conditioning and measurement procedures for both linear mass (mass per unit length) and areal mass (mass per unit area) on woven fabrics, including handling of full-width and folded fabrics and considerations for stretch constructions.

Q: Who typically uses it?

A: Textile manufacturers and converters, laboratory technicians performing QC tests, specification writers, procurement and inspection teams, and research groups working on fabric structure and performance.

Q: Is it current or superseded?

A: The ISO bibliographic record lists ISO 3801:1977 as the published first edition; ISO standards are periodically reviewed and the ISO record shows the standard has been maintained in ISO's system (periodic confirmation/review actions are recorded). For country-specific adoptions or translations check national standards bodies for any later national withdrawal or replacement.

Q: Is it part of a series?

A: It is part of the ISO/TC 38 textile fabrics standards family (tests and specifications for textile properties); users commonly apply it together with other ISO textile test standards (thickness, tensile tests, conditioning and atmosphere standards, etc.).

Q: What are the key keywords?

A: textile, woven fabric, mass per unit area, mass per unit length, areal density, g/m², fabric weight, conditioning, ISO 3801.
