防水材料检测的取样浙江同济科技职业学院主讲人：厉莎建筑材料与检测技术

依据标准1取样方法及数量2检测条件3StandardSamplingmethodandquantitesTestconditions目录

1依据标准Standard《建筑防水卷材试验方法》GB/T328.9-2007TestmethodforbuildingwaterproofrollsGB/T328.9-2007

2取样方法及数量Samplingmethodandquantites抽样基数不小于500m2。同一批次，同一规格型号产品随机抽取1卷，除去2.5m卷头后，沿纵向截取长度为2m的试样2块，其中1份为检验样品，另一份为备样；再在同批产品中随机抽取1卷后，除去2.5m卷头后，沿纵向截取长度为2m卷材试样1块，为复验用样品。Thesamplingbaseshallnotbelessthan500m2.Onevolumeisrandomlyselectedfromthesamebatchofproductswiththesamespecificationandmodel.Afterremovingthe2.5mcoilhead,twosampleswithalengthof2marecutalongthelongitudinaldirection,oneofwhichisthetestsampleandtheotheristhestandbysample.Afterrandomlyselecting1reelfromthesamebatchofproductsandremovingthe2.5mreelhead,1reelsamplewithalengthof2mwasinterceptedalongthelongitudinaldirectionforretest.

3检测条件Testconditions试样在送至试验室前，应原封放在干燥处并保持15~30℃范围内一定时间。物理性能所用的水应纳为蒸馏水或洁净的淡水（饮用水）；所用溶剂为化学纯或分析纯。Beforesendingthesampletothelaboratory,itshouldbekeptinadryplaceandkeptintherangeof15~30℃foracertaintime.Thewaterusedforphysicalpropertiesshouldbedistilledwaterorcleanfreshwater(drinkingwater);Thesolventusedischemicallypureoranalyticallypure.
