GEN
General requirements
Applies to every item in the sections below.
-
GEN.1 Scope

-
GEN.2 Authority requirements
The works shall comply with the requirements of [name the Authority Having Jurisdiction]. Where this section and the Authority differ, the Contractor shall notify the Engineer before ordering, and the more onerous requirement shall apply unless the Engineer instructs otherwise.
-
GEN.3 Equal products
Products of equal or better performance may be proposed. Each proposal shall include a clause by clause compliance statement against this section, listing every deviation, and shall be submitted for the Engineer's approval before order.
-
GEN.4 Submittals
For each model the Contractor shall submit: the product datasheet with dimensions, flow rates, materials and connections; the CE declaration of conformity where applicable; the manufacturer's quality management certificate; certificates or test reports for every standard claimed; the installation guide with fixing and plumbing details; warranty terms; the local service arrangement; and the lead time to site.
-
GEN.5 Materials in contact with drinking water
Materials in contact with drinking water shall hold a drinking water or hygiene approval from [name the scheme or body accepted by the Authority]. The approval document shall be included in the submittal.
-
GEN.6 Corrosion resistance near the coast
Exposed stainless steel at sites within [distance] of the coast shall be AISI 316 or a higher grade. A powder coated or other finish may be proposed if the manufacturer confirms in writing the exposure for which the finish is warranted.
AISI 316 has better corrosion resistance than 304, particularly to pitting in chloride environments. The same source notes that in hot chloride environments 316 is subject to pitting and crevice corrosion, and to stress corrosion cracking under tensile stress beyond about 50°C, so review surfaces exposed to sustained high temperatures.

EME
Emergency showers and eyewash units
