Complete Guide to ISO 4368 Calibration of Positive Displacement Flow Meters Laboratory Testing Service Provided by Eurolab

ISO 4368 is an international standard that outlines the requirements for the calibration of positive displacement flow meters. This standard is part of a series of standards developed by the International Organization for Standardization (ISO) to ensure the accuracy and reliability of measurement instruments.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ISO 4368 calibration testing is governed by various national and international standards, including:

  • European Union Directives (e.g., MDR, IVD, etc.)
  • US FDA regulations (21 CFR Part 11)
  • ISO 9001:2015 (Quality Management System)
  • ISO/IEC 17025:2017 (Competence of Testing and Calibration Laboratories)
  • These standards require that measurement instruments be calibrated regularly to ensure accuracy and reliability. Failure to comply with these standards can result in costly fines, product recalls, or even loss of business.

    Standard Development Organizations

    The standard development organizations responsible for the development and maintenance of ISO 4368 include:

  • International Organization for Standardization (ISO)
  • European Committee for Standardization (CEN)
  • American Society for Testing and Materials (ASTM)
  • These organizations collaborate to ensure that standards are harmonized across industries and regions.

    Evolution of Standards

    Standards evolve over time as new technologies emerge, and requirements change. For example, the introduction of new measurement instruments or changes in regulatory requirements may necessitate updates to existing standards.

    Eurolab stays up-to-date with the latest developments and revisions to ensure that our clients measurements are accurate and compliant with relevant regulations.

    Specific Standard Numbers and Scope

    The following standard numbers and scope apply to ISO 4368 calibration testing:

  • ISO 4368:2011(E) - Positive displacement flow meters - Part 2: Calibration
  • Specifies requirements for the calibration of positive displacement flow meters

  • ISO 8363:2009(E) - Measurement of liquids - Volume flow rate measurement using a volumetric meter
  • Specifies requirements for the measurement of liquid volume flow rates

    Industry-Specific Compliance Requirements

    Industry-specific compliance requirements vary depending on factors such as:

  • Country or region
  • Type of product or service being measured (e.g., medical devices, food products)
  • Level of accuracy required
  • Eurolab has extensive experience in various industries and can help clients navigate complex regulatory requirements.
