GOST 14326-73 PDF

Full title and description

GOST 14326-73 — "Ткани текстильные. Метод определения пиллингуемости" (Woven/textile fabrics — Method for determination of pilling). The standard defines a laboratory method to provoke and measure formation of pills on fabric surfaces using a pillingmeter and to report pilling results for quality control and material evaluation.

Abstract

This standard specifies a two-stage test procedure (formation of surface fuzz, then formation of pills) carried out on specified pilling test apparatus (examples: pilIingmetre types PMV-3 / PMV-4), with defined loads, motion parameters and cycle counts, and a visual counting/evaluation procedure that yields the maximum number of pills per defined area as the reportable result. It is intended for finished woven textile fabrics (excludes pile/velour and some technical fabrics).

General information

• Status: Withdrawn / not in force in the Russian Federation (standard has been removed from force).
• Publication date: Adopted 1973 (designation year) and introduced into force 1 January 1975; later reprinted editions and amendments exist (reprint 1999 with amendments).
• Publisher: Approved by the State Committee for Standards of the USSR (Gosstandart); later published/reprinted by IPK — Izdatel'stvo standartov (standards publishing house).
• ICS / categories: 59.080 (Textile fabrics / textiles); national classification references show OKS 59.080.30 / group M09.
• Edition / version: Original designation 14326-73 with published amendments in 1977, 1979, 1984 and 1989; later reprints include these amendments and at least one editorial correction.
• Number of pages: Short technical text — commonly listed as 7–8 pages depending on the edition/reprint.

Scope

Applies to finished woven textile fabrics and specifies a method to determine the fabric's propensity to form pills (pilling). The procedure is not intended for pile (velour/nap) fabrics and for certain technical fabrics; it describes apparatus, sample preparation, test conditions (loads, motion and cycles), visual assessment and result processing. Results are used to characterise pilling behaviour under accelerated abrasion conditions.

Key topics and requirements

• Test principle: two-stage formation — first fuzz (controlled oscillation) then pills (rotational or specified motion) followed by visual counting of pills per defined area.
• Apparatus: pillingmeter (example model references PMV-3, PMV-4) with specified holders, sample supports and lighting for visual assessment.
• Specified test parameters: example values in the standard include oscillation radius, loading on holders (approx. 500 g), surface pressure (approx. 50 g/cm²) and reference cycle counts for fuzz formation (e.g., 300 cycles) and further cycles for pilling assessment.
• Evaluation: count pills on each elementary specimen area (e.g., number of pills per 10 cm sample), compute arithmetic means for cycle points, and report the maximum mean rounded to an integer as the final pilling index.
• Reporting: include apparatus type, specimen orientation, conditioning atmosphere, number of specimens, cycles used, and numerical pilling results; note any deviations from the procedure.

Typical use and users

Used by textile testing laboratories, manufacturers (quality control and product development), R&D groups assessing fiber/yarn/treatment effects on surface appearance, procurement/specification engineers and standards bodies. Historically used in Soviet and post‑Soviet textile practice; today many laboratories reference modern international methods (ISO series) and ASTM equivalents for pilling testing.

Related standards

International and other national standards covering pilling and related surface-change tests include ISO 12945-1 (pilling box method) and ISO 12945-2 (modified Martindale method). ASTM test methods (for example ASTM D4970 / Martindale method and other ASTM pilling test methods) are commonly used alternatives. GOST 14326-73 historically replaced earlier GOST 14326-69; users often map test requirements between GOST text and ISO/ASTM methods when updating procedures.

FAQ

Q: What is this standard?

A: GOST 14326-73 is a Soviet-era / national standard titled "Ткани текстильные. Метод определения пиллингуемости" that specifies a laboratory method for provoking and counting pills on woven fabric surfaces to evaluate pilling propensity.

Q: What does it cover?

A: It covers test apparatus, specimen preparation, test conditions (loads, motion geometry and cycle counts), visual counting and processing of pilling results for finished woven fabrics; it excludes pile/velour and certain technical fabrics.

Q: Who typically uses it?

A: Textile test laboratories, QC departments in fabric and apparel manufacturing, R&D teams, standards organisations and procurement/specification specialists historically used the method; many modern labs now use ISO 12945 series or ASTM pilling methods for international alignment.

Q: Is it current or superseded?

A: The document has been removed from force in Russia (listed as having lost force / withdrawn) and reprints exist with amendments; in contemporary practice, laboratories often adopt ISO 12945 (pilling box and Martindale methods) or ASTM equivalents. Records indicate formal withdrawal/not-in-force status and removal from the national catalogue.

Q: Is it part of a series?

A: GOST 14326-73 replaced an earlier GOST 14326-69 and sits among textile testing standards addressing appearance and surface-change properties; pilling is also addressed internationally by the ISO 12945 series (Parts 1 and 2) and by multiple ASTM test methods.

Q: What are the key keywords?

A: Key keywords are pilling, pills, pilling resistance, textile fabrics, pillingmeter, PMV, fuzzing, visual assessment, pilling index.
