Reaction-to-fire testing analyzes how a material or product responds to a controlled fire challenge. Measurements can include how fast the material ignites, how much and how quickly heat is emitted, how much mass is lost, and how much smoke is produced.
The rate of heat release is considered to be a significant predictor of a potential fire hazard, and the cone calorimeter is a valuable bench-scale instrument in fire testing to quantitatively evaluate the relative risk that different materials pose.
Due to the relatively small specimen sizes used for the test, the cone calorimeter test is a cost-effective way to research the fire performance of products while still in the developmental stage, for assessing material compliance to established performance requirements, as on-going quality control, or even to generate data for litigation purposes.
Additional advantages to cone calorimeter testing are the ability to measure smoke production, which can play an important role in material selection for critical applications.

ISO 5660-1 Reaction to fire tests-Heat release, smoke production and mass loss rate-Part 1: Heat release rate (cone calorimeter method)
ISO 5660-1對(duì)火反應(yīng)試驗(yàn)—熱釋放、產(chǎn)煙量及質(zhì)量損失率,第1部分:熱釋放速率(錐形量熱儀法)
ISO 5660-1標(biāo)準(zhǔn)概述
錐形量熱試驗(yàn)是目前評(píng)估材料對(duì)火反應(yīng)最先進(jìn)的方法。測(cè)試按照物質(zhì)燃燒的耗氧原理即被測(cè)物質(zhì)與氧完全燃燒時(shí)消耗單位質(zhì)量氧所產(chǎn)生的熱量。
該方法是按照國(guó)際標(biāo)準(zhǔn)ISO 5660-1進(jìn)行測(cè)定的。
另外，在測(cè)試過程中可以對(duì)產(chǎn)煙量和煙霧毒性進(jìn)行測(cè)量。
該測(cè)試主要評(píng)估以下測(cè)試項(xiàng)目：
1 可燃性；
2 火焰?zhèn)鞑ィ?br/>3 產(chǎn)煙量；
4 煙霧毒性；
