Comprehensive Guide to ISO 7704 Membrane Filters for Microbiological Analysis Testing Services Provided by Eurolab

ISO 7704:2009 is an international standard that specifies the requirements for membrane filters used in microbiological analysis. The standard provides guidelines for the selection, use, and maintenance of membrane filters to ensure accurate and reliable results.

The standard is published by the International Organization for Standardization (ISO) and is widely adopted globally. In addition to ISO 7704, other relevant standards include:

  • ASTM E1110-15: Standard Practice for Testing Water-Media Filtration Apparatus

  • EN ISO 7704:2009: Water quality - Membrane filters used for microbiological analysis

  • TSE L10:2018: Turkish Standard for membrane filters used in water and wastewater treatment

    • The legal and regulatory framework surrounding this testing service is governed by national and international regulations, including:

  • European Unions (EU) Drinking Water Directive (98/83/EC)

  • US Environmental Protection Agencys (EPA) Safe Drinking Water Act

  • World Health Organizations (WHO) Guidelines for Drinking-Water Quality

    • Standard development organizations, such as ISO, ASTM, and EN, play a crucial role in developing and maintaining standards. These organizations bring together experts from various industries to create consensus-based standards that ensure consistency and quality.

    Standards evolve over time to address new technologies, methods, and regulations. Eurolab stays up-to-date with the latest developments and updates to ensure compliance with international and national standards.

    The test procedure for ISO 7704 membrane filters involves the following steps:

    1. Sample preparation: Collecting and preparing water or other liquid samples

    2. Filter selection: Selecting the appropriate filter type and size

    3. Filtration: Passing the sample through the filter under controlled conditions (temperature, pressure, etc.)

    4. Incubation: Incubating the filtered membranes at a specific temperature for a set period

    5. Reading: Measuring the growth of microorganisms on the membrane

    The testing equipment and instruments used include:

  • Membrane filters with specific pore sizes and materials

  • Filtration apparatus (e.g., vacuum pumps, pressure gauges)

  • Incubators (e.g., shakers, temperature-controlled units)

  • Microscopes and image analysis software for counting microorganisms

    • The testing environment requirements include:

  • Temperature: 20-25C (68-77F)

  • Humidity: 50-60

  • Pressure: <1 bar

  • Lighting: controlled conditions to prevent contamination

    • Sample preparation procedures involve collecting and preparing water or other liquid samples according to the standards guidelines.

    The test report should include:

  • Sample identification and description

  • Filter type and size used

  • Testing conditions (temperature, pressure, etc.)

  • Results of microbial analysis (counts, growth rates, etc.)

  • Interpretation of results

  • Certification and accreditation details

  • Traceability and documentation requirements

    • Eurolabs reporting standards and formats comply with international regulations and guidelines. The test report is a critical document that provides valuable information for regulatory compliance, product development, and quality assurance.
