Application to Multiple Aggregate Configurations
该语句为NEBS GR-63-CORE标准中的关于阻燃应用的一个方面.
Multiple Aggregate Configurations是什么意思呀?
5.2.4.2 Application to Multiple Aggregate Configurations
A variant on the needle flame test shall be used to determine whether structural or
energizable constituents,whose individual volumes do not exceed 1750 cubic mm,when arranged in multiple aggregates as in a subassembly,can cause flame spread to occur.The needle flame,as described by IEC 695-2-2,shall be applied for 20 seconds to the lowest mounted item of the multiple aggregate mounted in situ on the subassembly.On removal of the needle flame,if the resident flame condition does not spread to adjacent subassembly items,this constitutes evidence that the aggregate items are fire resistant in terms of Section 4.2.3.1.The test shall be made on three test specimens per configuration to ensure the repeatability of the results.
我还是不太确定,这个是全文,
