Active view current version of standard. Other Historical Standards. Work Item s - proposed revisions of this standard. More E The effective heat of combustion is determined from a concomitant measurement of specimen mass loss rate, in combination with the heat release rate. Smoke development is measured by obscuration of light by the combustion product stream. External ignition, when used, shall be by electric spark. The value of the heating flux and the use of external ignition are to be as specified in the relevant material or performance standard see X1.

The normal specimen testing orientation is horizontal, independent of whether the end-use application involves a horizontal or a vertical orientation. The apparatus also contains provisions for vertical orientation testing; this is used for exploratory or diagnostic studies only.

Examples of material specimens include portions of an end-use product or the various components used in the end-use product. No other units of measurement are included in this standard. 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.

ASTM E1354 – Cone Calorimeter

The ASTM E standard for the cone calorimeter sets out to determine the response of materials exposed to controlled levels of radiant heating with or without an ignition source. The cone calorimeter became the premier dynamic research tool based on the principle of oxygen consumption calorimetry. Radiant heat is the major cause of fire spread and the cone measures intensity of the peak rate of heat release PRHR and the speed to reach PRHR; the critical factors in predicting the growth rate of fire. Various output data are collected including peak rate and average rate of heat release, total heat released, effective heat of combustion, specific extinction area, exhaust flow rate, mass loss rate and final sample mass, time to sustained ignition, O2, CO, CO2, and toxic gas concentrations, and smoke density as a function of time. Setup The test apparatus consists of the following components: a conical radiant electric heater; specimen holders; an exhaust gas system with oxygen monitoring and flow measuring instrumentation; an electric ignition spark plug; a data collection and analysis system; and a load cell for measuring specimen mass loss. A photo of the apparatus is shown below.

ISO , , Accredited Laboratory. Why wait for accurate measurements and excellent service? ASTM E examines the relationship between the total heat produced during the combustion process and the oxygen needed for that combustion to occur. You can calculate this relationship based on the fact that about 13, kilojoules of heat are produced for every one kilogram of oxygen burned. Of course, taking precise measurements of factors such as oxygen concentration, weight loss of the test piece and time standards related to smoke production relies on using a fully qualified ASTM E test lab like VTEC Laboratories that has been conducting high-quality commercial testing for well over three decades.

This test method is used to determine the heat release rate and a number of other fire-test-response characteristics as a result of exposing insulating materials contained in electrical or optical cables to a prescribed heating flux in the cone calorimeter apparatus. Quantitative heat release measurements provide information that is potentially useful for design of electrical or optical cables, and product development. Heat release measurements provide useful information for product development by giving a quantitative measure of specific changes in fire performance caused by component and composite modifications. 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. The fire-test-response characteristics determined by this test method are affected by the thickness of the material used as test specimen, whether as a plaque or as coating on a wire or cable. The diameter of the wire or cable used will also affect the test results.
