Heat and Visible Smoke Release Rates for Materials and Products. ASTM D – 11 Standard Test Method for Using a Cone Calorimeter to Determine Fire-Test-Response Characteristics of Insulating Materials Contained in.
The test performance uses the bench-scale system to measure fire characteristics associated with heat and smoke output.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
E Terminology of Fire Standards. Classification for burning behavior of building materials and products. The value of heat release rate corresponding to the critical limit between propagating cable fires and non-propagating fires is not known. A photo of the apparatus is shown below.
All dimensions are in millimetres except where noted. These properties are determined on small size specimens that are representative of those in the intended end use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The value of the initial test heat flux and the use of external ignition are to be as specified in the relevant material or performance standard see X1.
Test for heat and smoke release rates for materials and products. External ignition, when used, shall be by electric spark. Work Item s – proposed revisions of this standard.
External ignition, when used, shall be by electric spark.
The ASTM E standard for the cone calorimeter sets out to determine the response ashm materials exposed to controlled levels of radiant heating with or without an ignition source. ISO Precision of test methods — determination of repeatability and reproducibility for a standard test method by inter-laboratory tests. The apparatus also contains provisions for vertical orientation testing; this is used for exploratory or diagnostic studies only.
Ee1354 development is measured by obscuration of light by the combustion product stream. The cone calorimeter became the premier dynamic research tool based on the principle of oxygen consumption calorimetry.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability or regulatory limitations prior to use.

Examples of material specimens astn portions of an end-use product or the various components used in the end-use product. All dimensions are in millimetres.
Work Item s – proposed revisions of this standard. Adequate safeguards for personnel and property shall be employed in conducting these tests.
Rotameter is on outlet of the oxygen O 2 analyzer. For specific hazard statements, see Section 7. The normal specimen testing orientation is horizontal, independent of whether the end-use application involves a horizontal or a vertical orientation. Heat release data from this test method will not be predictive of product behavior if the product will not spread flame over its surface under the fire exposure conditions of interest.
