Full title and description
Standard Specification for General Requirements for Zinc and Zinc Alloy Products — establishes uniform ordering, marking, sampling, and chemical-analysis practices that apply to zinc and zinc-alloy final products (ingots, slabs, jumbos, castings, and related forms).
Abstract
This specification sets general requirements (unless a product specification states otherwise) for ordering information, marking, and methods of sampling for chemical analysis common to zinc and zinc-alloy products. It describes sampling methods (sawing, milling, drilling, turning, clipping), color-code requirements for alloys, and how the specification interfaces with individual product specifications referenced within ASTM Committee B02.

Scope
Provides general, cross-cutting requirements for zinc and zinc-alloy products for use when product-specific specifications do not otherwise prescribe ordering, marking, or sampling procedures. The specification is intended to be applied in conjunction with numerous product specifications (ingot, wire, castings, anodes, etc.) and does not replace product-specific chemical- or mechanical-property requirements.
Key topics and requirements
- Ordering information and minimum data to be supplied by purchaser and supplier.
- Marking and identification of lots, ingots, slabs, jumbos, and finished products.
- Sampling procedures for chemical analysis (methods and when to sample — during casting, at customer site, dispute sampling, routine testing).
- Acceptable analytical methods (spectrochemical or chemical) for determination of composition.
- Color-code requirements for zinc casting alloy ingots and related identification practices.
- Notes on units (inch‑pound standard with SI conversions provided for information) and safety/regulatory responsibilities for users.
Typical use and users
Used by zinc and zinc-alloy producers, foundries, metal‑service centers, purchasers and procuring engineers, quality and metallurgical laboratories, specification writers, and standards committees to ensure consistent ordering, marking, and sampling practices across a range of zinc products. Also referenced by product‑specific ASTM specifications and by supply‑chain quality systems.
