近来，我们接到不少中国客户关于依据ISO/TR 13353(1994)标准对燃油滤清器进行性能测试的咨询，他们希望我们依据这个标准来进行试验。
ISO/TR 13353(1994) 是一个旧的标准，早在2002年8月29日就已经撤销了。我们向这些客户解释：我们IFTS还有一些可用的ACFTD，我们可以将测试得到的µm(c)转换成µm，这也是我们可以使用这个旧标准做测试的原因。
这些国内的客户说是他们的客户（即滤清器用户）要求他们使用这个标准进行燃滤性能测试。
本文将介绍这个燃油滤清器性能测试标准的升级。以期帮助广大滤清器用户和滤清器制造商了解这个标准的背景。
Recently, we have got some inquires for fuel filter testing according to ISO/TR 13353(1994) from the customers in China, they asked us to run test for them according to this standard.
ISO/TR 13353(1994) is an old test standard which has already been withdrew on August 29th of 2002. We explained that we have some more ACFTD available by IFTS and we can correlate from µm(c) to µm. That is the reason why we can work according to this old standard.
These Chinese customer told us their customers (the filter end users) ask them to use this standard to test the fuel filter.
This article introduces the upgrading of this testing standard for diesel fuel filters. Try to help filter users and filter manufacturers to understand the background of this testing standard.
