GOST R 57270-2016 PDF

Full title and description

GOST R 57270-2016 — "Building materials. Methods for combustibility tests" (Russian: "Материалы строительные. Методы испытаний на горючесть"). The standard specifies laboratory test methods for determining combustibility and classifying building materials by groups of combustibility.

Abstract

This national standard defines test procedures (including furnace and small-flame methods) to assess whether construction materials are non-combustible (NG1, NG2) or belong to combustible groups (G1–G4), and prescribes criteria and reporting requirements for classification. It adapts relevant international provisions (notably ISO 1182 family) for use in the Russian regulatory context.

Key bibliographic and status details consolidated from official and standards-library records.

Scope

The standard establishes test methods for assessing combustibility of construction materials and for assigning them to combustibility groups. It applies to solid building materials and layered materials (including some multilayer composites) and excludes liquid paints and varnishes and other materials supplied as solutions or powders. The procedures cover furnace tests, small-flame exposure, determination of heat of combustion and ancillary measurements required for classification.

Key topics and requirements

• Definitions of non-combustible groups NG1 and NG2 with numeric limits (e.g., allowable increases in furnace temperature, mass loss, duration of steady flaming and limits on heat of combustion) as criteria for non-combustibility classification.
• Classification of combustible materials into groups G1–G4 based on test results (temperature of combustion gases, degree of damage by length and mass, duration of self‑sustained burning, etc.).
• Detailed test methods: furnace (oven) non-combustibility test (method I), other complementary methods and small-flame direct exposure (method III), and determination of heat of combustion (method IV).
• Requirements for sample preparation, conditioning, instrumentation, calibration (including calibration with steel samples), and reporting of environmental/test conditions in the test protocol.
• Mandatory and informative annexes with test-rig arrangements, examples for multilayer materials, and procedures for heat-of-combustion measurement and calculation.

These technical requirements align the Russian procedures with relevant international test practices while specifying national criteria for classification.

Typical use and users

Used by testing laboratories, certification bodies, product manufacturers, construction designers, fire-safety engineers and regulatory authorities to: (1) determine combustibility class of building products; (2) support fire-safety design decisions and regulatory compliance; and (3) prepare test reports for product declarations, certification and acceptance testing.

Related standards

The standard references and aligns with international and national documents (notably ISO 1182 series / reaction-to-fire non-combustibility tests) and cross-references other GOST/GOST R documents concerning fire safety and test methods for related properties. It was prepared with technical input from national fire-safety institutes and testing centers.

FAQ

Q: What is this standard?

A: GOST R 57270-2016 is the Russian national standard that specifies laboratory methods to test and classify the combustibility of building materials.

Q: What does it cover?

A: It covers test procedures (furnace and flame-exposure methods), criteria for classifying materials as non-combustible (NG1, NG2) or combustible (G1–G4), sample preparation and reporting requirements; it excludes liquid paints/varnishes and materials supplied as powders or solutions.

Q: Who typically uses it?

A: Accredited fire-testing laboratories, manufacturers of building products, certifying bodies, fire-safety specialists, designers and public authorities responsible for construction and fire-safety compliance use the standard to assess and document material combustibility.

Q: Is it current or superseded?

A: The document was approved on 18 November 2016, published 25 November 2016 and introduced (date of entry into force) 1 May 2018. Contemporary standards registries and libraries list it as the applicable national document for these test methods; users should verify the current status with the national standards body or an authorized standards provider before making regulatory decisions.

Q: Is it part of a series?

A: It is a stand‑alone GOST R standard for combustibility test methods but is technically linked to related fire-safety standards and international test standards (for example, ISO 1182 family) that cover reaction-to-fire test principles.

Q: What are the key keywords?

A: combustibility, non-combustible, NG1, NG2, G1, G2, G3, G4, heat of combustion, furnace test, small-flame test, building materials, fire testing.
