2. Buildings (premises) of fire protection engineering and fire protection classification rating 2.1. Building materials and constructions

2.1.1. Building materials and constructions after burning (reaction to fire) broken down into the following groups: non-combustible (degtnespējīg), burning (hard combustible) and burning (combustible) — see. UR2.1.tab. Combustion properties of building materials group was appropriate. Mutual economic assistance (SEV) Standard ST and ST THEMSELVES 382-76-80 of 2437 HIMSELF.
2.1.2. Building materials and building characteristics depending on the toxicity of combustion products, and the ability to burn to create the smoke down under former USSR State standard GOST 12.1.004.89.
table 2.1 of combustion properties of materials and constructions of the group characteristics of the materials of construction are subjected to fire the incendiary source, do not ignite and smolders not charred.
Of non-combustible materials.
Difficult burning by the incendiary source, ignites, smolders or charred in the presence of a source of ignition and continue to burn, smolder or charred, but it stops after termination of exposure to burn, smolder or charred.
From hard combustible materials or from combustible materials from fire or high temperature exposure, protected by non-combustible materials.
Burning by the incendiary source, ignites, smolders or charred and lighter exposure ended, continues to burn, smolder or charred.
From combustible materials.
2.2. Building structures and products 2.2.1. Building and fire safety of products characterized by their fire resistance limit and burning.
2.2.2. Buildings and fire resistance limit of a product defines the time (in minutes) from the beginning of the examination of the fire until there's one such building or product concerned fire resistance: 1) after choked performance or stability — R;
2) by viengabalainum (whole) — E;
3) after the heat capacity — I; 4) after ensuring that the critical temperature of the material in the test free of load: W. Fire resistance limit stands in accordance with internationally accepted choked designations (R, E, s, W) and with a number that indicates the period of time when there's one of choked. For example, R-120 fire resistance limit of 120 minutes after the constructions of load or resistance; REI 60 fire resistance limit: 60 minutes, which is the smallest of the three, after which the tested choked construction. After these methods may be more structural integrity. For example, R-120; REI 60 – 120 fire resistance limit of building minutes after the performance or stability and 60 minutes after the viengabalainum (whole) or siltumizolēšan.
