ASME A112.1070-2015/ASSE 1070-2015/CSA B125.70-15

This is the first edition of ASSE 1070/ASME A112.1070/CSA B125.70, Performance requirements for water
temperature limiting devices. It

(a) supersedes ASSE 1070:2004, Performance requirements for water temperature limiting devices; and
(b) replaces the requirements for automatic temperature limiting devices in CSA B125.3, Plumbing
fittings.

This Standard covers water temperature limiting devices intended to limit the hot or tempered water
temperature supplied to fittings for fixtures such as sinks, bidets, lavatories, and bathtubs to reduce the risk
of scalding. These devices are not designed to address thermal shock.
