ASTM WK88414
Revision of A123/A123M-17 Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products
Rationale
Interference with intended use is not permitted, but the term “intended use” is not defined in A123. The “intended use” clause was introduced to require the hot-dip galvanized coating avoid interfering with the objective or function of a product (functional features, required fit-up to other parts, or ability to be painted or powder coated). Surface conditions which are primarily aesthetic in nature do not affect the intended use of the product but may result in confusion over calls for rejection if the product did not “turn out as intended.”
A definition of “intended use” is proposed in 3.2.5 and additional verbiage (see 6.4.1 and 6.2) is proposed to clarify intended use is different from intended appearance. Additionally, the proposed verbiage in 6.2 aims to address concerns over the removal of surface conditions which would prevent surfaces from mating properly (e.g. faying surfaces).
There is a need to clarify how the purchaser can request additional finish/appearance requirements for AESS (Architecturally Exposed Structural Steel), duplex systems (paint or powder coating over hot-dip galvanizing) or other projects requiring elevated aesthetics. Proposed paragraph 6.4.1 aims to address purchaser requests for elevated aesthetic requirements.
