GOST 8551-2021 PDF

Full title and description

GOST 8551-2021 — Grease ЦИАТИМ-205 (CYATIM‑205). Specifications. The standard specifies technical requirements, testing and acceptance rules, and packaging/marking for the plastic (paste) grease known as ЦИАТИМ‑205.

Abstract

This national standard defines the composition, required physical and performance properties, test methods, safety and marking requirements for CYATIM‑205 grease used to seal and prevent seizure (galling) of threaded connections and seals that contact aggressive media. It includes service temperature limits (operational range down to −60 °C for static joints and −20 °C minimum for moving threaded connections, up to +50 °C) and requirements for packaging and storage.

Scope

The standard applies to the plastic grease CYATIM‑205 intended for sealing and preventing seizing of stationary threaded connections and seals exposed to aggressive media and operating in a temperature interval from −60 °C to +50 °C. For moving threaded connections the minimum recommended temperature of use is −20 °C. The document sets requirements for composition, performance, test methods, safety, packaging, marking, transport and storage.

Key topics and requirements

• Designation and identification of CYATIM‑205 grease (nomenclature and marking).
• Physical and chemical property limits (consistency, drop point, stability, water resistance and resistance to selected aggressive media).
• Operational temperature limits and performance requirements for static and moving threaded connections.
• Methods of sampling and standardized test methods to verify compliance (acceptance testing and laboratory methods).
• Packaging, marking, transport and storage instructions and manufacturer guarantees.
• Safety and handling requirements, including references to applicable occupational safety and hazardous‑materials provisions.

Typical use and users

CYATIM‑205 grease per GOST 8551‑2021 is typically used by maintenance and assembly teams, procurement and quality laboratories in oil & gas, petrochemical, chemical processing, utilities, machine‑building and pipeline operations where threaded joints and seals require long‑term anti‑seize and sealing performance in aggressive environments and low temperatures. Engineers specifying sealing greases, purchasing departments, and testing laboratories are the primary users.

Related standards

Replaces or updates requirements from earlier national editions such as ГОСТ 8551‑74. Related normative references include standards for test methods, safety (occupational and chemical handling standards) and classification standards for lubricants (e.g., ISO/ICS lubricant classification series). National and international lubricant standards and test methods (ISO, ASTM) are commonly used alongside this GOST.
