Certification Guidelines
Flow Sciences is your partner for all your containment needs. For detailed assistance in the certification of your system, please refer to our certification guidelines. Designed for certifiers, metrologists and other persons responsible for ensuring the enclosures are correctly configured, this document should be used in conjunction with the user manual provided with the enclosure. For ‘standard’ style enclosures, simply refer to this style within the certification guidelines document. For ‘custom’ enclosures, please refer to the Introduction and Description sections to identify which enclosure type should be used for certification. The document also includes a troubleshooting guide for the more common issues. If you still have questions, please do not hesitate to contact us.
