| 摘 要： | 线缆行业大力发展低烟无卤线缆和材料,此类产品都要求测量烟密度.烟密度值是试样在规定试验条件下测得的,不同测量方法得到的试验结果不同,不能认为是试样的固有性能.材料烟密度试验方法标准新版GB/T 8323-2008与原GB/T 8323-1987存在诸多差异,线缆烟密度试验方法标准GB/T 17651-1998(IEC ...

| Abstract: | There are a large number of low smoke zero halogen wires and cables and their raw materials in our industry.Need to determine the specific optical density of smoke generated by these products.The density of smoke generated by a specimen was determined under the specified exposure conditions.Values determined by a test method are not to be considered inherent fundamental properties of the specimen.Values determined by different test methods are not same.The new edition of standard GB/T 8323—2008 is different with the old edition GB/T 8323—1987.The standard GB/T 17651—1998(IEC 61034—1997) is different with UL 2556—2007(9.9).The report describes these differences. |
