Full title and description

GOST 30402-96 — Building materials. Ignitability test method. National (interstate) standard that defines a laboratory test procedure to determine the ignitability of building materials and to classify them into ignitability groups.

Abstract

This standard specifies a controlled laboratory method combining a radiative heat flux and an open ignition source to determine time-to-ignition and the critical surface heat flux of homogeneous and layered combustible building materials; results are used to assign materials to prescribed groups of ignitability. The method is based on internationally recognized test principles (references include ISO 5657) and describes specimen preparation, equipment (radiation panel, movable burner), calibration, test sequence and reporting.

General information

• Status: Active / in force (introduced 01 July 1996).
• Publication date: 1 July 1996 (GOST designation: 30402-96).
• Publisher: Adopted and published as an interstate / national GOST standard under the auspices of the Russian system of standards; developed by ЦНИИСК (V.A. Kucherenko Research Institute) together with VNIIPO and submitted by the Ministry of Construction.
• ICS / categories: 91.100 (building materials), fire safety: 13.220.50 (fire resistance / combustibility of building materials).
• Edition / version: Original issue 1996 (designation ends with “-96”); no widely published later superseding edition noted in referenced registries (standard remains listed as active).
• Number of pages: Typically listed as 32 pages (some databases record 33 pages).

Scope

Applies to all homogeneous and layered combustible building materials. Establishes the laboratory procedure to determine whether and when a specimen ignites under a prescribed combination of radiative heat flux and an open ignition source, and defines classification criteria by critical surface heat flux and ignition time. The standard includes specimen dimensions, conditioning, equipment design, calibration, test sequence and reporting requirements.

Key topics and requirements

• Principal test concept: exposure of a specimen to a controlled radiative heat flux with an open burner to register time-to-ignition and determine the critical surface heat flux (KППТП).
• Equipment: radiation (flux) panel, movable and auxiliary burners, specimen holder with moving platform, protective plate and measurement instruments; detailed dimensional and construction requirements are provided.
• Calibration: mandatory calibration of the radiative panel and measurement instruments before testing.
• Test sequence: conditioning and preparation of specimens, exposure at stepwise heat flux levels (examples in the method include 40, 20 and 10 kW/m² as reference levels), observation period (up to 15 min per exposure) and repeat tests to determine critical flux.
• Classification and reporting: assignment of a material to an ignitability group based on measured critical heat flux and recorded ignition behaviour; test report content is standardized (laboratory, sample description, measured parameters, observations).
• Safety and laboratory requirements: ventilation, electrical safety and operator protection per referenced occupational and safety standards.

Typical use and users

Used by fire-test laboratories, manufacturers of construction and finishing materials, certification bodies and regulatory authorities to evaluate and classify the ignitability of building products for product documentation, conformity assessment and fire-safety selection in construction projects. Test data support certification, regulatory compliance and material selection in building design.

Related standards

References and related documents include ISO 5657 (principles used in development), national fire-safety and material test standards (for example GOST 30244-94 on combustibility and other GOST/GOST‑R fire-test series). Laboratories typically apply this test in combination with other reaction-to-fire and smoke/toxicity tests when assessing overall fire performance.

FAQ

Q: What is this standard?

A: GOST 30402-96 is a Russian/interstate standard that defines a laboratory method to assess the ignitability of building materials and to classify them by ignitability groups.

Q: What does it cover?

A: It covers specimen preparation, required test equipment (radiation panel and burners), calibration, the stepwise test procedure to measure time-to-ignition and critical surface heat flux, reporting format and safety requirements; it is intended for homogeneous and layered combustible construction materials.

Q: Who typically uses it?

A: Accredited fire-test laboratories, material manufacturers, certification and conformity-assessment bodies, and regulatory authorities evaluating fire performance of construction products.

Q: Is it current or superseded?

A: Database listings consulted show GOST 30402-96 as active (introduced 01 July 1996). No single universally published superseding edition was found in the referenced registries; users should verify the current legal/regulatory status in the appropriate national/regional standards registry before relying on the standard for certification or compliance.

Q: Is it part of a series?

A: It is part of the family of fire-reaction and fire-safety standards used for construction materials (works alongside standards on combustibility, fire resistance and smoke generation); it was developed with reference to ISO 5657 principles and is used in combination with related GOST/GOST‑R fire-testing methods.

Q: What are the key keywords?

A: Ignitability, time-to-ignition, critical surface heat flux, building materials, combustible, radiative panel, ignition test, classification.
