Full title and description

O’z DSt 604:2016 — "Пахта толаси. Техникавий шартлар" (Cotton fibre — Technical specifications). This is the Uzbekistan national standard that defines technical requirements and classification for cotton (lint) fibre used in production, trade and certification.

Abstract

O’z DSt 604:2016 specifies quality requirements, classification rules and the principal parameters used to grade cotton fibre (e.g., length, micronaire, strength, colour/appearance, impurities and moisture) and identifies accepted testing/measurement approaches (including use of HVI measurements as reference quality indicators). The standard entered into force in 2016 and has been applied in certification and trading of Uzbek cotton.

General information

• Status: Current national standard (adopted 2016; amended by official order in 2021).
• Publication date: 2016 — introduced into force on 25 August 2016.
• Publisher: Uzbekistan state standards authority / Uzstandard (national standardization agency).
• ICS / categories: Textile technology — Textile fibres / natural fibres (ICS reference area: 59.060.10 / textile fibres).
• Edition / version: O’z DSt 604:2016 (replaces O’z DSt 604:2001; amendments issued in 2021).
• Number of pages: Not specified in the public registry entries consulted (varies by published copy).

Scope

Defines technical requirements, classification and acceptance criteria for lint cotton (pахта толаси) intended for industrial processing and trade. The standard sets quality classes and limit values for key fibre characteristics, references approved sampling and test methods, and is used as the regulatory basis for certification of cotton shipments and quality control in Uzbekistan. The 2021 amendments harmonise certain classification elements with international/national references (examples cited in the amendment include alignment with China's GB 1103:2007 and the USDA Agricultural Handbook 566).

Key topics and requirements

• Definitions and terms for cotton fibre (lint) and associated raw material states.
• Quality characteristics and grading parameters: fibre length distribution, micronaire (micronaire/micronaire-related index), tensile strength, colour and external appearance, impurity content and moisture content.
• Classification system and grade limits for different cotton types (including reference classes used for trade and inspection).
• Reference measurement methods and instrumentation (HVI instrumentation accepted as reference for many quality indicators; other standardised laboratory methods for specific tests are referenced or required).
• Requirements for marking, packaging, handling, storage and conditions for maintaining declared quality during shipment/transport (used in certification practice for consignments).

Typical use and users

Used by cotton producers and ginneries, quality control and testing laboratories, certification bodies, exporters, commodity traders, terminal operators and textile mills for grading, acceptance testing, certification and contractual quality assurance of cotton consignments.

Related standards

Part of a family of Uzbekistan cotton/textile standards (examples: O’z DSt 614 — sampling methods for cotton; O’z DSt 618 — maturity; O’z DSt 619 — strength measurement; and later O’z DSt documents on colour, impurities, length and moisture measurement). The 2016 standard replaced the 2001 version and has had subsequent linked updates (see official 2021 amendment documents for cross-references to O’z DSt 629, 632, 633, 634 and O’z DSt 3295:2018 among others).
