GOST R 50810-95 PDF

Full title and description

ГОСТ Р 50810-95 — «Пожарная безопасность текстильных материалов. Ткани декоративные. Метод испытания на воспламеняемость и классификация». English: "Fire safety of textile materials — Decorative textiles — Flammability test method and classification". The standard specifies test methods, specimen preparation and classification rules for decorative textile materials (curtains, draperies, stage and wall textiles) with respect to their tendency to ignite and sustain burning.

Abstract

This standard establishes a vertical/flame exposure test procedure and classification criteria that partition decorative textile materials into categories (e.g., easily flammable vs. difficult to ignite) based on measured parameters such as residual burning time, length of charred zone, surface flash propagation and ignition of cotton wadding from falling particles. It is intended to support fire-safety selection, product specification and regulatory assessment of interior textiles.

General information

• Status: Active (document in force as a national standard of the Russian Federation).
• Publication date: Adopted / published 1995 (text dated 23 October 1995); entered into force 1 January 1996.
• Publisher: National standard of the Russian Federation (GOST R); developed by fire-safety research experts (listed sources indicate All‑Russian Research Institute for Fire Protection / relevant national technical committee).
• ICS / categories: OKC / ICS fields for the document include textile technology and fire safety — commonly indexed under 13.220.40 and 59.080.30.
• Edition / version: Original 1995 national standard (GOST R 50810-95); administrative updates and references appear in later bibliographic listings (text maintained as the 1995 edition in national collections).
• Number of pages: 12 pages (typical electronic/printed edition length reported in standards catalogs).

Scope

Applies to combustible decorative textile materials supplied to consumers and used for interior decoration and public spaces (for example: curtains, draperies, stage and scenery textiles, blackout fabrics and similar vertically suspended decorative fabrics). The standard defines sample sizes, conditioning, ignition arrangements and classification rules to evaluate resistance to ignition and sustained burning. It is not the general upholstery or mattress standard and other GOSTs cover some applications (carpets, bedding, upholstery) where different test methods or additional requirements may apply.

Key topics and requirements

• Specimen preparation and conditioning (sample dimensions, orientation in warp/weft directions, pre‑conditioning at 20 ±2 °C and 65 ±2 % RH prior to testing).
• Ignition arrangements and exposure times (specified burner positions and sequences, e.g., surface ignition with short flame exposure and alternative edge ignition procedures when sustained burning is not observed; exposure times and angles defined to obtain the most severe response).
• Measured parameters: residual burning time after removal of ignition source, presence/absence of flame spread over the surface, length of charred zone, ignition of cotton wadding from falling particles or dripping, and occurrence of surface flash propagation.
• Classification criteria: threshold limits (examples in the standard) such as residual burning longer than 5 s on a specimen, average char length above specified millimetre limits, or cotton-wadding ignition lead to classification as easily flammable; otherwise material may be classed as more fire‑resistant under the standard's categories.
• Testing protocol includes repeat testing rules (when single-sample results are borderline) and options for testing treated (flame‑retardant) textiles both before and after accelerated hydrolysis to assess durability of treatment.

Typical use and users

Primary users include textile and curtain manufacturers, product safety and compliance laboratories, certification bodies, fire-safety engineers, architects and specifiers for public buildings and venues (theaters, hotels, restaurants, schools) where decorative textiles are installed, and regulatory/supervisory authorities performing fire-safety inspections. The standard is referenced in fire-safety oversight and inspection guidance for the Russian Federation.

Related standards

GOST R 50810-95 sits alongside other national and regional standards for fire properties of textiles and building materials (examples referenced in bibliographies and guidance include later GOSTs addressing flame-spread indices for fabrics and other GOST R standards for upholstery and textile products). Users often apply GOST R 50810-95 together with complementary test methods when a broader fire-safety assessment is required.

FAQ

Q: What is this standard?

A: A Russian national standard (GOST R 50810-95) that specifies a flammability test method and classification criteria for decorative textile materials such as curtains and stage fabrics.

Q: What does it cover?

A: It covers specimen preparation, conditioning, specific burner/ignition procedures, measured outcomes (burn time, char length, cotton‑wadding ignition, surface flash) and rules for classifying materials as easily flammable or more fire‑resistant for interior decorative use.

Q: Who typically uses it?

A: Textile manufacturers, test laboratories, certification bodies, fire-safety inspectors, architects/specifiers and venue operators responsible for selecting and certifying decorative textiles in public and commercial spaces.

Q: Is it current or superseded?

A: The document is the 1995 national standard (GOST R 50810-95) entered into force 1 January 1996 and is listed as active in national standards catalogs; users should check national repositories or standards services for any later revisions or harmonized regional regulations before relying on a single edition.

Q: Is it part of a series?

A: It is part of the body of GOST/GOST R standards dealing with fire safety of materials and textile testing; several other GOST/GOST R documents address related topics (e.g., flame-spread indices, upholstery and other textile applications) and are commonly used in combination.

Q: What are the key keywords?

A: Decorative textiles, flammability test, classification, curtain safety, vertical burn, residual burning time, char length, fire safety of textiles.
