# TMV service record

Record the valve and outlet, intended users, hot and cold inlet temperatures, mixed outlet temperature and manufacturer failsafe test result. Keep the measured settings and procedure reference.

The structure below is the form as Tradehand implements it — the fields a trader fills in and the certificate renderer prints — not a reproduction of any published model form.
