Thermostatic Mixing Valve Testing
Kiwa Watertec is accredited to test thermostatic mixing valves.
Our robust testing procedure confirms that your product is safe, reliable and fit for purpose, based on established standards EN1111, EN1287, NHS Specification D08.
Apart from meaningful, rigorous testing, we offer a unique costing structure. Clients pay for the initial product test, and annual factory production control audits. As long as the product doesn’t change, there is no need for repeat testing. When additional models or changes are necessary, the process is very smooth. This approach can accommodate a developing product range.
Thermostatically controlled valves are widely available to control the temperature of water for showering, bathing and hand-washing and provide the solution to scalding, by blending hot water with cold to ensure constant, safe outlet temperatures. These valves should be particularly considered in areas where people would be at the highest risk of scalding.
These valves can described as:
Type 1 - Mechanical mixing valves
Type 2 - Thermostatic mixing valve conforming to EN 1111 and EN 1287
Type 3 - Thermostatic mixing valve complying with NHS Estates requirements D08
A Thermostatic Mixing Valves (TMV) Type 3 approval ensures that the valves are manufactured to meet the highest specifications required by the NHS Estates D08 standard for mixing valves for use within health care premises in the United Kingdom. Although Type 3 thermostatic mixing valves are predominantly used in the healthcare industry they can be used in all types of buildings.
See Normal Conditions for Type 2 and 3 TMV valves. Kiwa certification is accepted for these designations for Type 3 testing in accordance with DO8.
