GOST 9087-81 PDF

Full title and description

GOST 9087-81 (ГОСТ 9087-81) — "Флюсы сварочные плавленые. Технические условия" / "Welding melted fluxes. Specifications". The standard establishes technical requirements, marks (grades), test methods, packaging, marking and rules for use of fused (melted) welding fluxes intended for automatic and mechanized arc welding and surfacing, and for electroslag welding of steel for domestic needs and export.

Abstract

This standard specifies the allowed grades of melted welding fluxes, their chemical and physical requirements (including permissible impurity limits and grain sizes), methods of sampling and testing (humidity, chemical analysis, granulometry), marking, packaging, storage and transport, and safety/occupational controls for working with fluxes used in mechanized welding and surfacing processes. It includes normative references and amendments that update certain requirements.

General information

Scope

Applies to fused (melted) welding fluxes intended for automatic and mechanized electric-arc welding and surfacing of steels, and for electroslag welding of steel; intended for use in national industry and for export. The standard defines which flux marks are covered and gives recommendations for application in combination with specific filler wires and steels.

Key topics and requirements

• List of standardized flux marks/grades covered (examples include: АН‑384‑А, АН‑348‑АМ, АН‑348‑В/ВМ, ОСЦ‑45/ОСЦ‑45М, АН‑8, АН‑15М, АН‑17М, АН‑18, АН‑20С/20СМ/20П, АН‑22, АН‑26, АН‑43, АН‑47, АН‑60, АН‑65, ФЦ‑9, etc.) and recommendations for their use.
• Chemical composition limits and classification of fluxes by oxide content and potentially hazardous components; permissible airborne concentrations and occupational safety notes for handling flux dust and fumes.
• Physical requirements including grain-size categories (glass-like and pumice-like), bulk density, humidity limits and allowable impurity levels, tailored to automated welding wire diameters and process types.
• Sampling, test methods and acceptance rules (humidity determination, chemical analysis, granulometry, and reporting of test results).
• Marking, packaging, storage and transportation requirements (label content, bag/container marking, climatic storage categories). (xn--59-dlclat8cged8a.xn--p1ai)

FAQ

Q: What is this standard?

A: GOST 9087-81 is an interstate (former USSR) standard titled "Welding melted fluxes. Specifications" that sets technical requirements, test methods and handling/packaging rules for fused welding fluxes used in mechanized and automatic welding and surfacing processes.

Q: What does it cover?

A: It covers flux marks (grade list), chemical and physical requirements (including grain size and humidity), sampling and laboratory test methods, marking, packaging, storage/transport, and occupational safety guidance related to flux use.

Q: Who typically uses it?

A: Manufacturers and suppliers of welding fluxes, welding shops (automated/mechanized welding), shipbuilders, fabricators, quality and standards departments, procurement specialists, and regulatory bodies overseeing welding consumables and workplace safety.

Q: Is it current or superseded?

A: Databases and standards libraries list ГОСТ 9087-81 as действующий (active) with recorded amendments (references to amendments issued in the late 1980s–1990s). Users should verify the current legal/regulatory status in their jurisdiction and check for any more recent regional or national replacements.

Q: Is it part of a series?

A: It belongs to the family of GOST standards for welding consumables and processes; it replaced earlier GOSTs on melted fluxes (e.g., ГОСТ 9087-69) and references multiple related safety and testing standards. Many organizations treat it together with other GOST/R and ISO-related welding standards when specifying consumables.

Q: What are the key keywords?

A: Flux, melted flux, welding flux, welding consumables, mechanized welding, automatic welding, electroslag welding, surfacing, flux grade, quality requirements.
