TMV Certification

NSF offers verification testing and certification services for the TMV2 and TMV3 UK-based certification requirements.

We offer TMV2 testing and certification against the updated performance standards BS EN 1111:2017 and BS EN 1287:2017.

We test to these standards for a wide variety of temperature designations and types.

TMV2-designated thermostatic mixing valves are compliant with BS EN 1111:2017 (high pressure) and/or BS EN 1287:2017 (low pressure) and are used in domestic properties or other domestic type situations to reduce the risk of scalding.

TMV3-designated thermostatic mixing valves are verified as compliant with the performance specification D 08 for valves used in high-risk areas of health care premises.

This robust performance-based specification ensures the safety of vulnerable people including children, older people, those with reduced mental capacity and users who are unable to react to prevent injury while washing or bathing.
