坐便器用水量测试方法的比较

COMPARISON OF DIFFERENT TEST METHODS FOR WATER CONSUMPTION OF WATER CLOSET

坐便器用水量是重要的检测指标,各国标准的测试方法有一些差异,而不同的测试方法对测试结果有一定的影响。在此比较了坐便器用水量测试的中国标准(GB 6952-2005)、美国/加拿大标准(ASME A112.19.2-2008/CSA B45.1-08)、欧盟标准(EN 997:2003/A1:2006)、澳大利亚标准(AS 1172.2-1999)四个标准。通过对相同样品的4种测试方法试验,得出了测试结果之间的差异性。结果表明,ASME/CSA方法的用水量(大冲和小冲)和GB方法基本一致,EN方法的用水量(大冲和小冲)比ASME/CSA和GB方法的小,AS方法的平均用水量最小。

edWater consumption of water closet is very important.There are differences among test methods of different countries,and test results are influenced by different test methods.The paper compares test methods of GB 6952-2005、ASME A112.19.2-2008/CSA B45.1-08、EN 997：2003/A1：2006 and AS 1172.2-1999.According to testing the same sample with four test methods,test results show that there are differences among four test methods.Testing results show water consumption（full-flush and reduced flush） according to ASME/CSA method basically is same with water consumption according to GB method.Water consumption（full-flush and reduced flush） according to EN method is less than water consumption according to ASME/CSA and GB methods.The average water consumption according to AS method is the least.
