GOST 8845-87 PDF

Full title and description

ГОСТ 8845-87 — "Полотна и изделия трикотажные. Методы определения влажности, массы и поверхностной плотности" (English title: Knitted fabrics and garments. Methods for determination of moisture, mass and surface density). The standard establishes sampling and laboratory methods to determine moisture content, the actual mass of knitted semi-finished products and garments, and surface (areal) density for raw and finished knitted fabrics and articles made from all types of yarns and their combinations.

Abstract

This interstate standard specifies procedures for sampling and laboratory measurement of: moisture content; actual mass of knitted semi-finished products, cut pieces and finished garments; actual and calculated surface (areal) density; and surface density and mass at normalized moisture. It applies to both untreated (raw) and finished knitted fabrics, knitted semi-finished products (coupons, sets of parts, parts) and finished knitted garments.

Scope

The standard covers sampling and laboratory test methods for knitted textile materials and end-products: raw and finished knitted fabrics, knitted semi‑finished goods (coupons, sets of parts, component parts) and finished garments made from any yarn types or combinations. It defines procedures to determine material moisture, the factual mass of pieces and finished items, actual and calculated areal (surface) density, and measurement of mass/density after conditioning to normalized humidity. The methods are intended for design, production control and quality assurance.

Key topics and requirements

• Rules for sampling representative specimens from knitted fabrics, coupons and finished articles.
• Method for determination of moisture content (conditioning and gravimetric moisture measurement).
• Procedure to measure actual mass of knitted semi‑finished products and finished garments.
• Methods for determination of actual and calculated surface (areal) density (mass per unit area).
• Procedure to determine surface density and mass at normalized (standardized) humidity conditions.
• Definitions and terms relevant to knitted fabrics and measurement practice (provided as an annex/applicable notes in the standard).

These topics form the standard's test-method structure (sampling; moisture; mass; surface density; conditioning).

Typical use and users

Designed for textile manufacturers, laboratory technicians, quality‑control and inspection bodies, research and development departments in knitwear production, standards writers, and certification authorities. Typical applications include incoming material inspection, in‑process control, final product verification, product development and preparation of technical documentation (specifications and TUs).

Related standards

GOST 8845-87 is part of a cluster of knitted-fabric test standards and is frequently cited alongside related documents such as GOST 8844 (acceptance and sampling rules for knitted fabrics), GOST 8846-87 (methods for linear dimensions, skew, stitch counts and yarn length in loop), GOST 8847-85 and general knitted-fabric technical specifications (e.g., GOST 28554-90). The standard appears as a normative reference in other textile standards and technical regulations.

FAQ

Q: What is this standard?

A: ГОСТ 8845-87 is a USSR / interstate standard that specifies laboratory methods for determining moisture content, mass and surface (areal) density of knitted fabrics, knitted semi‑finished products and garments.

Q: What does it cover?

A: It covers sampling procedures and test methods for moisture, actual mass of pieces and finished items, actual and calculated surface density, and determination of mass/density after conditioning to normalized humidity for raw and finished knitted textile products.

Q: Who typically uses it?

A: Manufacturers of knitwear and knitted fabrics, quality-control laboratories, certification and inspection bodies, textile R&D and technical documentation authors.

Q: Is it current or superseded?

A: Public standards registries list ГОСТ 8845-87 as active (in force) with introduction on 1 January 1989; it replaced the earlier ГОСТ 8845-77. Some library entries note later reprints or reenactments; users should verify current national adoption status for their country before relying on it for certification.

Q: Is it part of a series?

A: Yes — it is one of several knitted‑fabric test-method standards (for example, standards addressing sampling and acceptance, linear dimensions and stitch counts, and other test methods in the 8844–8847 series and related textile GOSTs). These documents are commonly used together for comprehensive testing and quality control of knit products.
