What is KM within Russian Fire-safety certification system?
Update: On May 3, 2021, introduction of amendments to the Federal Law dated July 22, 2008 No. 123-FZ "Technical Regulations on Fire Safety Requirements" were discussed.
KM classes might be replaced by fire hazard indicators.
Fire Safety Certificate is an official document which confirms compliance of the products with the Russian national fire safety standards and regulations.
According to Technical Regulation of the Russian Federation (Federal Law No. 123-FZ dated 10.07.2012), there are six classes of fire hazards of building materials (KM0 – KM5) which is characterized by the following properties:
1. Combustibility (G)
- G1 - slightly combustible
- G2 - moderate combustible
- G3 - normal combustible
- G4 - most combustible
2. Flammability (B)
- B1 - hard inflammable
- B2 - moderate inflammable
- B3 - easy inflammable
3. Ability to spread flame over the surface (RP)
- RP1 - non-spread
- RP2 - weakly spread
- RP3 - moderately spread
- RP4 – highly spread
4. Smoke-forming ability (D)
- D1 - low smoke generation capacity
- D2 - moderate smoke generation capacity
- D3 - high smoke generation capacity
5. Toxic combustion products (T)
- T1 - low risk
- T2 - moderate hazardous
- T3 - highly dangerous
- T4 - extremely dangerous
Depending on the fire risk groups Building materials are divided into the following classes of fire hazard:
Fire hazard properties of Building materials
Fire hazard class of construction materials, depending on the groups
Toxic combustion products
Ability to spread flame over the surface
These characteristics are evaluated during the test of the samples. After the test, Fire Safety certificate indicating the class of fire hazard is issued.
Usually, when building the public places of mass gathering (school, hotel, hospital etc.) materials with high fire hazard properties (KM0, KM1) are used.
