GOST 16363-98 PDF

Full title and description

GOST 16363-98 — "Средства огнезащитные для древесины. Методы определения огнезащитных свойств" (English title: "Fire protective means for wood. Methods for determination of fire protective properties"). The standard specifies laboratory methods to determine the fire-protective performance of coatings and impregnations applied to wood and defines classification criteria used for certification and quality control.

Abstract

This interstate (GOST) standard sets out two complementary test procedures — a classification method and an accelerated control test — for assessing the fire-protective properties of materials intended for protection of wood. The methods evaluate the behaviour of treated wood under controlled fire exposure by measuring parameters such as mass loss and char characteristics, and assign an effectiveness group based on prescribed thresholds. The standard is used for type testing, certification and production quality control of fire-retardant coatings and impregnants for timber.

General information

• Edition / version: GOST 16363-98 (replaces GOST 16363-76). Primary edition from 1998 (implemented 1999); recorded editorial update in 2002.
• Number of pages: 11 pages (typical published copy).

Scope

The standard applies to fire‑protective preparations for wood (surface coatings and impregnations) and establishes: (a) a classification (type) test method for determining the fire‑protective efficiency group of a protective means, suitable for certification and product marking; and (b) an accelerated (control) test method intended for production or batch control of materials already classified. The core measurement is the mass loss of treated wood samples after exposure under defined fire/heat accumulation conditions; test procedures include sample preparation, application regimes, burning protocol and result recording.

Key topics and requirements

• Two test methods: a classification (type) method for assigning fire‑protective efficiency groups and an accelerated (control) method for production control.
• Core test metric: mass loss of treated wood samples after controlled fire exposure (used to quantify protective performance).
• Defined effectiveness groups (typical thresholds used in the standard): Group I — mass loss not more than ~9%; Group II — mass loss from ~9% to ~25%; greater than ~25% — composition is considered not to provide effective fire protection (i.e., fails classification).
• Requirements for sample preparation, number of specimens, application method (coating vs impregnation), recording of dry residue and consumption (kg/m² or kg/m³), and environmental/test conditions (temperature, humidity) during testing.
• Mandatory test protocol and reporting format (protocol forms and required fields for batch/lot identification, product brand, test conditions and measured results).
• Use of classification results for certification decisions and the accelerated method for routine control of production lots and after‑treatment verification.

Typical use and users

Primary users are manufacturers and formulators of fire‑retardant coatings and impregnation systems for wood, independent testing laboratories, certification bodies and regulatory authorities responsible for fire safety certification. Secondary users include architects, building code officials, fire safety engineers and researchers assessing treated timber materials for use in construction and interior applications.

Related standards

GOST 16363-98 is part of a suite of fire‑safety and wood‑treatment standards. Commonly referenced or related documents include the earlier national GOST it replaces (GOST 16363-76) and other fire‑behaviour and classification standards such as GOST 30244 (classification by flammability groups), related test and material standards referenced in the normative annexes (standards on sample preparation, wood properties and measurement techniques). Internationally, it sits alongside standards addressing fire‑retardant‑treated wood and surface coatings (for example NFPA/ASTM and relevant EN/ISO methods) though testing details and classification criteria differ by system and jurisdiction.

FAQ

Q: What is this standard?

A: GOST 16363-98 is an interstate standard that defines laboratory methods to determine the fire‑protective properties of products used to protect wood (coatings and impregnations). It provides procedures for assigning effectiveness groups and for routine control testing.

Q: What does it cover?

A: It covers two test methods — a classification method used for certification and determining an effectiveness group, and an accelerated (control) method intended for production quality control. The tests measure changes (notably mass loss) of treated wood after fire exposure under specified conditions and prescribe reporting formats.

Q: Who typically uses it?

A: Manufacturers of fire‑retardant preparations, independent testing laboratories, certification authorities, regulatory agencies and fire‑safety specialists involved in evaluating or approving treated wood products for building use.

Q: Is it current or superseded?

A: As published, GOST 16363-98 replaced GOST 16363-76 and is recorded as the operative standard (status: active). The standard was adopted in 1998, came into force 1 July 1999 and has documented editorial entries recorded up to 2002. Users should confirm with national/regional standards authorities for any subsequent amendments or replacements before relying on it for certification.

Q: Is it part of a series?

A: Yes — it forms part of the national/regional body of standards for fire safety and wood treatment; it is typically used together with other GOSTs and technical regulations dealing with flammability classification, fire testing methods and material safety for wood and building materials.

Q: What are the key keywords?

A: Fire protective means, wood, fire retardant, mass loss, classification, accelerated test, impregnation, coating, fire‑protective efficiency group, GOST 16363-98.
