    usually the plumbing code for domestic hot water. Here is section 607.1.2 from the 2015 International Plumbing Code as an example

    607.1.2 Tempered water temperature control. Tempered
    water shall be supplied through a water temperature
    limiting device that conforms to ASSE 1070 and shall
    limit the tempered water to a maximum of 110ºF (43ºC).
    This provision shall not supersede the requirement for protective
    shower valves in accordance with Section 424.3.
