Full title and description

GOST 3640-94 — Zinc. Specifications (Цинк. Технические условия). This interstate (GOST) standard specifies requirements and technical conditions for primary zinc products, including ingots and blocks, for use in metallurgical and industrial applications.

Abstract

Standard GOST 3640-94 defines mandatory quality requirements, acceptance rules and general technical conditions for primary zinc (ingots and blocks). It was developed by VNIItsvetmet and adopted as an interstate standard; the document superseded the earlier GOST 3640-79 and was introduced into the Russian system from 1 January 1997.

• Status: Active / in-force (interstate standard adopted and used as national/regional standard in CIS states; reissued editions noted).
• Publication date: Introduced 1 January 1997 (adopted October 21, 1994; implementation date 1997-01-01).
• Publisher: Interstate Council for Standardization, Metrology and Certification (EASC) / adopted and introduced by national Gosstandart bodies (implemented in the Russian Federation through Gosstandart).
• ICS / categories: ICS 77.120.60 (non-ferrous metals: zinc).
• Edition / version: Original designation GOST 3640-94 (1994 adoption / 1997 introduction); recorded reissue noted (June 2011).
• Number of pages: 8 pages (typical published PDF length).

Scope

The standard applies to primary zinc supplied as ingots and blocks. It establishes mandatory product-quality requirements (see section 4 of the standard), normative references, acceptance and testing rules, marking, packaging and storage provisions appropriate for primary zinc intended for industrial use.

Key topics and requirements

• Product definition and designation for primary zinc ingots and blocks.
• Mandatory quality requirements and acceptance criteria for supplied lots (surface condition, geometric dimensions, mass, and conformity to specification sections).
• Reference to normative testing methods and safety/occupational requirements for handling zinc products.
• Packaging, marking and storage requirements to preserve zinc quality during transport and storage.
• Procedures for sampling, laboratory testing and conformity assessment used for acceptance.

Typical use and users

Manufacturers and processors of non-ferrous metals, zinc refineries, foundries and smelting operations, metal traders and distributors, quality control laboratories, procurement and inspection departments in industrial companies, and regulatory/certification bodies use this standard to specify and verify the quality of primary zinc shipments.

Related standards

GOST 3640-94 replaces GOST 3640-79. Related and referenced standards commonly include other GOSTs covering sampling and test methods, occupational safety and handling of metallic materials, and standards for lead, tin and zinc alloys and products (examples of related GOSTs are listed in national catalogues alongside 3640-94).
