ISO 7704 Performance Testing of Microbial Filters: A Comprehensive Guide

Iso 7704 performance testing of microbial filters is a laboratory test that evaluates the effectiveness of microfiltration or ultrafiltration systems in removing bacteria, viruses, and other microorganisms from water. This test is governed by international standards such as ISO 7704:2008, which specifies the requirements for evaluating the performance of microfiltration or ultrafiltration systems.

Legal and Regulatory Framework

The testing service is subject to various regulations and laws that govern laboratory testing and calibration services. The following are some of the key regulatory frameworks:

  • ISO 17025: General requirements for the competence of testing and calibration laboratories

  • EN ISO 15288: Water quality - Determination of the bacterial and viral removal efficiency of drinking water treatment processes

  • TSE (Turkish Standards Institution): Turkish standards that regulate laboratory testing services

    • International and National Standards

    The following are some of the key international and national standards that apply to this specific laboratory test:

  • ISO 7704: Performance evaluation of microfiltration or ultrafiltration systems

  • ASTM F2297: Standard practice for evaluating the effectiveness of water treatment processes using biological indicators

  • EN ISO 15288: Water quality - Determination of the bacterial and viral removal efficiency of drinking water treatment processes

    • Standard Development Organizations

    The following are some of the key standard development organizations involved in developing standards related to laboratory testing services:
