GOST 1415-93 PDF

Full title and description

GOST 1415-93 — Ferrosilicon. Technical requirements and conditions of delivery. The standard specifies technical requirements, quality grades, testing, marking, packaging and delivery conditions for ferrosilicon supplied to the metallurgical and foundry industries.

Abstract

This national (interstate) standard defines the composition, allowable impurities, physical characteristics (including fraction sizes), sampling and laboratory testing procedures, inspection and acceptance rules, marking, packing and delivery conditions for commercial ferrosilicon (FeSi). It is intended to ensure consistent quality of ferrosilicon used as a deoxidizer and alloying agent in steelmaking and foundry processes.

Scope

GOST 1415-93 covers ferrosilicon produced for supply to metallurgical and foundry enterprises. It establishes requirements for chemical composition and permissible impurities, grain (fraction) sizes, mechanical and visual acceptance criteria, methods of sampling and testing, quality marking, packing, storage and delivery conditions. The standard applies to commercially traded grades of ferrosilicon used for deoxidation and alloying in steel and cast-iron production.

Key topics and requirements

• Specification of chemical composition ranges and maximum allowable impurities (e.g., C, P, S, Al, Mn and other trace elements) for marketed FeSi grades.
• Definition of commercial grades/marks (commonly used grades such as FeSi with specified silicon content) and associated quality criteria.
• Fraction (particle) size classes and requirements for sizing and sizing tolerances for shipment.
• Sampling and laboratory test methods for chemical and physical properties; acceptance and rejection rules.
• Marking, packaging, storage and transport/delivery conditions to preserve quality during shipment.
• Requirements for documentation, certificates of conformity and supplier declaration at delivery.

Typical use and users

Primary users are metallurgical and foundry plants, ferroalloy producers, raw-material traders, quality control and testing laboratories, procurement and logistics departments that buy or certify ferrosilicon for steelmaking and foundry applications.

Related standards

GOST 1415-93 references and aligns with international/interstate practice for ferroalloys; it is associated with the earlier national edition GOST 1415-78 (which it supersedes) and is linked to the international standard ISO 5445-80 for ferroalloys. Other national GOST standards covering ferroalloy sampling, testing and related materials form a related set used by producers and purchasers.

A: GOST 1415-93 is the Russian/interstate standard that specifies technical requirements and delivery conditions for ferrosilicon (FeSi), a ferroalloy used in metallurgy and foundry operations.

Q: What does it cover?

A: It covers chemical composition limits, allowable impurities, fraction (grain) sizes, sampling and laboratory test procedures, acceptance rules, marking, packaging, storage and delivery conditions for ferrosilicon shipments.

Q: Who typically uses it?

A: Metallurgical and foundry plants, ferroalloy manufacturers and suppliers, procurement and quality-control laboratories, and regulatory or conformity-assessment bodies involved with ferroalloy trade and use.

Q: Is it current or superseded?
