What Does The Testing Tell Us?
There are four different parts to this standard which are used to measure heat release,
***oke production and mass loss rate.
Part 1: This part of the standard detailed the test method used to determine the heat release from a material. Heat release is a measure of the contribution that a burning material makes to a fire in progress. A high rate of heat release may produce a high rate of temperature increase in surrounding unburnt material and accelerate fire spread.
Part 2: This part of the standard provides information relating to how the ***oke production rate can be calculated during the test described in part 1. The ***oke density measurement taken from a material under fire conditi*** gives an indication of the visibility through the ***oke, this is important as reduced visibility makes it more difficult to escape from a fire hence increasing the threat to human life from the toxic gases, flames and heat.
Part 3: This part of the standard provides guidance on taking measurements whilst conducting the tests detailed in part 1 and part 2. It examines the limitati*** of the cone calorimeter as currently used for building products and recommends ways in which some of these may be overcome for other types of products for other application areas.
Part 4: This part of the standard specifies a method for evaluating materials and products that produce low levels of heat release when exposed to high heat flux (i.e. irradiance levels) typical of fully developed fires.
When Is This Test Conducted?
This test is called upon in a number of different specificati*** and specific contracts. An example of when this test is called upon is in GM/RT 2130 for seat products for UK rolling stock and prCEN 45545-2 for European rolling stock in the future.
The test may also be conducted in order to obtain information which may be used in order to rank products and for modelling work.
