GOST ISO 23529-2020 PDF

Full title and description

GOST ISO 23529-2020 — "Резина. Общие методы приготовления и кондиционирования образцов для определения физических свойств" (English title: Rubber — General methods for preparing and conditioning test pieces for determination of physical properties). This GOST is the Russian adoption of ISO 23529 (third edition, 2016) and preserves the international standard's scope and requirements while presenting them in the national document format.

Abstract

This standard specifies general procedures for the preparation, measurement, marking, storage and conditioning of rubber test pieces to be used in physical test methods given in other standards. It defines preferred laboratory conditions (temperature, humidity), specimen preparation techniques (cutters, moulding, thickness control), conditioning times and environments, and requirements for the interval between forming and testing to ensure reproducible results. The document excludes special conditions for particular tests, materials or finished products.

Scope

Applies to the general methods for preparing, identifying, storing and conditioning rubber test pieces used for determination of physical properties in other standards. It sets preferred laboratory temperature and humidity, specimen-dimension measurement methods, equipment/techniques for cutting or moulding specimens, conditioning procedures (including conditioning chambers and times for elevated or subnormal temperatures) and the recommended time intervals between specimen formation and testing. Special conditions for particular tests, materials, climatic simulations or whole-product testing are excluded.

Key topics and requirements

• Standard laboratory conditions: specified normal temperature and relative humidity ranges for sample preparation and testing.
• Specimen identification and record keeping to ensure traceability of sample history and preparation parameters.
• Preparation techniques: cutters (fixed, replaceable, rotary), moulding of test sheets and specimens, thickness adjustment methods and maintenance of cutting tools.
• Conditioning procedures: defined conditioning times and temperatures for standard, elevated and subnormal conditions and guidance on conditioning equipment (temperature chambers, refrigeration, fluidized beds, cryogenic options).
• Measurement methods: four measurement methods for specimen dimensions depending on size, including non-contact methods where appropriate.
• Requirements for the time interval between forming and testing of specimens to avoid variability caused by post-formation changes.

Typical use and users

Used by materials and quality laboratories, rubber product manufacturers, test houses, R&D departments, certification bodies and standards committees. Typical applications include preparation and conditioning of specimens for tensile, hardness, compression, aging and other physical tests on raw and vulcanized rubbers to ensure consistent, reproducible results and agreement between suppliers and customers.

Related standards

Directly related to and referenced by many rubber testing documents. Normative and commonly associated standards include ISO 23529's normative reference ISO 1795 (sampling and preparative procedures for raw rubber) and test-specific standards such as ISO methods for tensile testing, hardness, accelerated ageing and others that rely on consistent specimen preparation and conditioning. Examples of related documents: ISO 1795 (sampling), and various ISO test method standards for rubber physical properties.

FAQ

Q: What is this standard?

A: It is the Russian national adoption (GOST ISO 23529-2020) of ISO 23529 (third edition, 2016), providing general methods for preparing and conditioning rubber test pieces for physical property determination.

Q: What does it cover?

A: It covers identification, record keeping, preferred laboratory temperature and humidity, specimen preparation (cutting and moulding), thickness control, conditioning procedures and times, measurement of specimen dimensions, and requirements for the interval between forming and testing. It does not include special conditions for specific tests, materials or finished products.

Q: Who typically uses it?

A: Test laboratories, rubber and elastomer manufacturers, quality control and R&D teams, certification bodies and standards developers who need consistent specimen preparation and conditioning to produce reproducible physical test results.

Q: Is it current or superseded?

A: GOST ISO 23529-2020 is the current national adoption of ISO 23529:2016. The underlying ISO text (ISO 23529:2016) is the third edition and was confirmed as the active ISO edition; users should verify any later amendments or revisions from national or ISO publications if absolute up-to-date confirmation is required.

Q: Is it part of a series?

A: It is a general/referential standard for rubber specimen preparation and conditioning and is commonly used together with many ISO and national standards that specify particular physical test methods for rubber (tensile, hardness, ageing, compression, etc.). It complements, but does not replace, test-specific standards.

Q: What are the key keywords?

A: Rubber, test piece, specimen preparation, conditioning, laboratory conditions, storage, measurement, GOST, ISO 23529.
