GOST 30388-95 PDF

Full title and description

GOST 30388-95 — "Полотна и изделия трикотажные. Метод определения пиллингуемости" (Knitted fabrics and garments. Method for determination of pilling). The standard specifies a laboratory method using a rotating‑chamber device (commonly UPOZ‑1 or equivalent) to determine pilling (formation of small balls of fibers) on knitted fabrics and finished knitted garments intended for outerwear, stockings and panty‑hose.

Abstract

This standard defines sampling, specimen preparation, test apparatus, conditioning, test procedure (including specimen mounting on rubber tubes), test duration (rotating chamber for 3 hours), pilling counting using a 100×100 mm template divided into sectors, and calculation of results as the arithmetic mean of four elementary specimens. It is intended for quality control, product development and acceptance testing of knitted textiles.

General information

• Status: Withdrawn / ceased in the Russian Federation (application ceased from 30 June 2025 / replaced in practice by the newer ISO‑based standard).
• Publication date: Designation year 1995; introduced (date of entry into force) 1 July 1996; registration/approval in 1996.
• Publisher: Interstate (regional) standard published under the authority of the State Committee for Standardization (Gosstandart) / national standards bodies (originally issued as a CIS/Interstate standard).
• ICS / categories: Textile standards / knitted fabrics — OKS/ICS codes shown as 59.080.30 and 61.020 (textile testing / knitted fabrics).
• Edition / version: GOST 30388‑95 (1995 designation). Often cited as identical to or aligned with earlier national text (ГОСТ Р 50025‑92).
• Number of pages: 4 pages (concise method standard).

Scope

The standard applies to knitted fabrics and knitted garments made from all types of yarns and combinations of yarns where pilling performance is relevant — including fabrics for outerwear and hosiery (socks, stockings, pantyhose). It establishes the laboratory method for determining the number/extent of pills formed under controlled abradant/rotation conditions and the calculation of a pilling index from multiple elementary specimens.

Key topics and requirements

• Sampling and specimen selection rules (elementary specimens 105×105 ±1 mm; four elementary specimens per test).
• Specimen preparation and conditioning requirements (edge overstitching, climatic conditioning per referenced GOST 10681).
• Test apparatus and mounting: rotating chamber device (UPOZ‑1 or equivalent), rubber tubes (≈30 mm diameter, specified length and end rings) to hold specimens.
• Test cycle and duration: chamber rotation for 3 hours (specified in the procedure).
• Pill counting and evaluation: use of a 100×100 mm counting template (nine sectors), count pills per sector, sum counts, and report arithmetic mean across four specimens (rounded to integer).
• Result processing: calculations to one decimal then rounded; reporting conventions and acceptance criteria are user/contract dependent (standard gives the measurement method rather than pass/fail limits).

Typical use and users

Primary users are textile testing laboratories, quality control departments of knitted‑goods manufacturers, R&D and product development teams, procurement and specification engineers, and regulatory/standards personnel who require a standardized pilling test for knitted products. The method is used for batch control, comparative testing of yarns/fabrics/finishes, and verification of product claims concerning pilling resistance.

Related standards

Relevant and related documents include: ГОСТ R 50025‑92 (related national text), referencing standards for sampling and conditioning (e.g., GOST 8844, GOST 10681, GOST 5496), and — as the modern replacement — the ISO‑based standard ГОСТ ISO 12945‑1‑2022 (Textiles — determination of pilling by the pilling box method), which now serves as the contemporary normative reference in the Russian system.

FAQ

Q: What is this standard?

A: It is a GOST method (designation 30388‑95) that specifies a laboratory procedure for determining pilling of knitted fabrics and garments using a rotating‑chamber pilling tester.

Q: What does it cover?

A: It covers sampling, specimen preparation and mounting, apparatus description (tube and chamber arrangement), test duration (3 hours), pill counting using a 100×100 mm template, and result calculation (mean of four specimens). The standard defines the test method rather than fixed pass/fail limits.

Q: Who typically uses it?

A: Textile and quality laboratories, knitted‑goods manufacturers, R&D teams, and anyone needing a repeatable method to measure pilling performance of knitted materials.

Q: Is it current or superseded?

A: Official sources indicate that GOST 30388‑95 has been withdrawn (application ceased in the Russian Federation as of 30 June 2025) and that ISO‑aligned methods (notably ГОСТ ISO 12945‑1‑2022 / ISO 12945‑1) are the applicable contemporary reference for pilling testing. Users should adopt the ISO‑based method where current compliance or alignment with up‑to‑date national practice is required.

Q: Is it part of a series?

A: The standard is a single‑method normative document for pilling of knitted goods; related standards and series include other textile test standards (sampling, conditioning and alternative pilling/pilling‑box methods such as ISO 12945 parts). The modern practice is to follow the ISO series on pilling where adopted.

Q: What are the key keywords?

A: Pilling, knitted fabrics, knitted garments, pilling resistance, rotating chamber, UPOZ‑1, pill counting, textile testing, GOST 30388‑95.
