1 Scope This British Standard specifies performance and material requirements and gives test methods for three types of TMV, of nominal size up to and including DN25, for use in care establishments . The TMVs covered by this standard are those which are suitable for the hot and cold water supply pressures and temperatures given in Table 1, and those which are suitable for the applications given in Table 2.
Annex A to Annex E give the apparatus and test methods for the durability of TMVs, Annex F to Annex M and Annex O to Annex S give the apparatus and test methods for the performance of TMVs. Annex N gives an assessment of transient values, Annex T gives a summary of thermal performance requirements and Annex U and Annex V give recommendations for commissioning and in-service tests.
