WRAS and NSF/ANSI 61 — how we list potable-water grades

Hong Kong specifications for potable water often mention WRAS or NSF/ANSI 61. This catalog tags a grade only when the LOCTITE Sourcebook 2024 or Golden Range Catalogue 2022 lists that approval — for example LOCTITE 565 (NSF/ANSI 61) and LOCTITE 577 (WRAS). Confirm the current certificate for the lot you will install.
