标题:ASTM D635水平燃烧测试方法<br/>
正文:<br/>
ASTM D635是对于水平位置塑料的燃烧速率或者蔓延程度及燃烧时间的测试。更多关于ASTM D635测试内容情况，请咨询南京睿督公司，咨询电话：025-8658 3475。ASTM D635: Standard test method for rate of burning and/or extent and time of burning of plastics in a horizontal position.ASTM D635:水平位置塑料的燃烧速率或蔓延程度及燃烧时间的测试.ASTM D635测试方法此方法为测定硬质（自承塑料）的燃烧速率的测试，此方法类似于UL 94HB法。只是样品的尺寸略有不同。从样品任意端点作标记，在距离100m处作为另一个标记。样品的长边水平放置，短边与水平边成45&amp;deg;角。以蓝焰长20mm的本生灯火焰施加于样品30s，如样品燃烧达100mm标记处，测定平均燃烧速率(mm／min)；如试样燃烧未达100mm标记处即自熄，测定平均燃烧时间(s)和平均燃烧长度(mm)，根据有关建筑规范将塑料分级。ASTM D635等级分为A、B、C、D四个等级ASTM D635 Class A: there is no visible sign of combustion after the source is removed.ASTM D635 Class B: The flame front does no pass the 25mm reference after the source is removedASTM D635 Class C: The flame front does pass the 25mm but does not reach the 100mm reference mark.ASTM D635 Class D: The flame front reaches the100mm reference mark and the linear burning rate does not exceed 40mm/min for specimens.ASTM D635样品要求125mm*13mm*厚度ASTM D635测试周期及费用：更多关于ASTM D635测试周期及费用，详情请咨询南京睿督公司，咨询电话：025-8658 34<br/><a href="https://www.firete.com/blog/wap.asp?mode=WAP&amp;act=View&amp;id=2689&amp;Page=1">[&lt;&lt;]</a><a href="https://www.firete.com/blog/wap.asp?mode=WAP&amp;act=View&amp;id=2689&amp;Page=1">[[1]]</a><a href="https://www.firete.com/blog/wap.asp?mode=WAP&amp;act=View&amp;id=2689&amp;Page=2">[2]</a><a href="https://www.firete.com/blog/wap.asp?mode=WAP&amp;act=View&amp;id=2689&amp;Page=2">[&gt;&gt;]</a><br/>
