  Abstract:Linear dimensional stabilityis one of the key properties for TPO waterproofing material. Firstly,comparing the testing method for TPO linear dimensional stability between ASTM D6878—11a and GB 27789—2011. Secondly,the effects of test instruments, specimen cutting sample,test selection markers,specimen size,and test conditions(such as temperature,heat treated specimens) on testing results of TPO dimensional stability were studied. Results show that these parameters should be carefully detailed to obtain an usefulexperiment result.
