ISO 9705-1 Reaction to Fire Tests - Room Corner Testing for Wall and Ceiling Covering Products - Part 1: Test Method for a Small Room Configuration

In the standard “ISO 9705-1 Reaction to fire tests - Room corner test for wall and ceiling covering products - Part 1: Test method for a small room configuration” developed by the International Organization for Standardization (ISO), it is stated that when mounted on the surface of a small room and directly on a specified A test method used to evaluate the fire response of wall and ceiling products when exposed to an ignition source is described.

This test method represents a fire scenario that starts under well-ventilated conditions in the corner of a room with a single open door.

Tests performed in accordance with the method specified in this standard provide data for the early stages of a fire, from ignition to deflagration. However, this method does not evaluate the fire resistance of products.

This test method is not designed to evaluate floor coverings. This method is based on sandwich panel building systems (ISO 13784 Reaction to fire testing for sandwich panel building systems), pipe insulation (ISO 20632 Reaction to fire tests - Small room testing for pipe insulation products or systems) and specific ISO standards (ISO 13785 Reaction to fire for facades). tests) are not suitable for the facades where they are available.

The ISO 9705-1 standard aims to describe the fire behavior of a product under controlled laboratory conditions. The test method can be used as part of a fire hazard assessment that considers all actors involved in assessing the fire hazard of a particular end use.

For the purposes of this standard,

• Exposed surface refers to the surface of the product subjected to the heating conditions of the test.
• Material refers to a single substance or evenly dispersed mixture (for example, this includes metal, stone, wood, concrete, mineral fibers and polymers).
• Product refers to the material, composite or assembly that requires knowledge about.
• A sample is a representative piece of the product to be tested along with any substrate or process (the sample may contain an air gap).
• Wall and ceiling covering product are wall and ceiling products that are installed on the surface of a room and are directly exposed to a specific ignition source.
• Flashover is the point in the fire history when the sum of heat from the ignition source and the product reaches 1000 kW. It is the heat release rate calculated as a 30-second rolling average, as given in the standard annex.
• Fire growth rate is the rate at which a fire grows over a given period of time.
• Smoke growth rate is the rate at which smoke grows over a given period of time.
• Burning droplets refer to the continuous formation of flaming droplets/particles from the sample for at least 10 seconds or until a pool fire occurs on the ground.

In principle, the danger of fire growth is assessed by measuring the heat release rate of the fire based on the calculation of oxygen consumption. The danger of reduced visibility is estimated by measuring the production of light-blocking smoke. Events attributed to fire growth, such as flame spread and dispersion of burning droplets, are visually documented through photography and video recording.

If more information is needed, measurements can be made, for example heat flow to the floor, types of toxic gases, gas temperature in the room and mass flow into and out of the doorway.

Among the numerous testing, measurement, analysis and evaluation studies our organization provides for businesses in various sectors, with its trained and expert staff and advanced technological equipment, "ISO 9705-1 Reaction to fire tests - Room corner test for wall and ceiling covering products - Part 1 It also provides testing services defined in the "Test method for a small room configuration" standard.
