当电流通过导体愈大，热效应愈高，发热量也愈大。当多种电器的电流通过多联插座时，电流愈大其热效应愈高，超过额定值后就会烧毁电线和插座，严重时就会引起火灾。所以切记使用电源插座不要小马拉大车。
These methods of fire tests are applicable to door assemblies of various materials and types of construction for use in wall openings to retard the passage of fire
Tests made in conformity with these test methods register performance during the test exposure; and such tests shall not be construed as determining compliance for use after exposure to fire
It is the intent that tests made in conformity with these test methods develop data to enable regulatory bodies to determine the compliance of door assemblies for use in locations where fire resistance of a specified duration is required.
These methods are intended to evaluate the ability of a door assembly to remain in an opening during a predetermined test exposure
The tests expose a specimen to a standard fire exposure controlled to achieve specified temperatures throughout a specified time period, followed by the application of a specified standard fire hose stream. The exposure, however, is not representative of all fire conditions, which vary with changes in the amount, nature, and distribution of fire loading, ventilation, compartment size and configuration, and heat sink characteristics of the compartment. It does, however, provide a relative measure of fire performance of door assemblies under these specified fire exposure conditions.
UL 10B门配件耐火极限测试－标准概述：
根据标准规定的性能测试方法出具测试报告，报告中显示指定的时间下的耐火性能，如下：20min，30min，60min，90min或120min等等。测试报告应包括试验炉的温度测量，选定未暴露的面进行测量，其中也包括所有装备性能的观察和记录。
