查询词典 retardant

According to the most unfavorable fire scenario for safety evaeuation, the AEST can be obtained through the spread of fire and smoke spread simulation. And the REST of different staff loads are calculated by empirical formula method. Through contrasting two times, whether evacuation passage setting can meet the evacuation requirements is confirmed, and then solutions are proposed.

以厦门金山寨隧道为例分析火灾时人员的安全疏散，针对隧道内最不利人员安全疏散的火灾场景进行分析，通过对火灾蔓延、烟气扩散进行模拟获得可用的人员安全疏散时间AEST，并用经验公式法计算不同的人员荷载下必需的人员安全疏散时间REST，对比两个时间，判别当前疏散通道的设置是否满足人员疏散要求，并对不满足安全疏散要求的工况提出解决方案。

The result shows that the requirements and testing methods for flammability of building materials are similar between the United State and Canada, and they mainly are engaged in the test of combustibility and flame spread. In European Union, a new classification system for flammability of building materials was implemented in 2001, which includes two systems; one is for floor coverings and the other for all other building units. In Japan, the interior materials are classified into non-combustible, quasi noncombustible and fire-retardant materials according to Cone Calorimeter method (ISO 5660). China has established a non-combustible test, a three-class classification system for combustible wall and ceiling interior finishing materials and a two-class classification system for combustible floor coverings.
