GOST 2488-79 PDF

Full title and description

GOST 2488-79 — "Ceresin. Specifications" (Russian: «Церезин. Технические условия»). The standard defines technical requirements, grades and testing/handling rules for ceresin, a refined mineral wax used in lubricants, wax blends, insulating materials and other industrial applications.

Abstract

GOST 2488-79 sets composition, physical and chemical property limits, grading (marks 65, 70, 75, 80 and 80э), safety, acceptance, test methods, packaging, marking, transportation and storage rules for ceresin produced by acid‑contact refining of crude ceresin. It excludes ceresin intended for food applications. The standard includes later amendments extending its period of application.

General information

• Status: Active / in force (limitation of validity removed by protocol of the interstate standards body).
• Publication date: Approved 30 May 1979; date of application/entry into force 01 January 1981.
• Publisher: Gosstandart of the USSR (State Committee for Standards) — original issuing authority; later reprints/collections issued by standards publishers.
• ICS / categories: OKC/ICS 75.140 (Paraffins, bituminous materials and other petroleum products); KGS category B42 (petroleum products and related).
• Edition / version: Original designation GOST 2488-79 (approved 1979); reprints and compilations published later (notably reissues within collections around 2000); contains amendments recorded in 1985 and 1990.
• Number of pages: Typical published text: 6–10 pages depending on edition/reprint.

Scope

The standard applies to industrial ceresin obtained by acid‑contact purification of crude ceresin and intended for use in production of lubricants, wax mixtures, insulating materials and similar technical purposes. It specifies marks (by drop‑point/softening point and intended uses), test methods, acceptance rules, packaging, marking, transportation and storage. It does not cover ceresin intended for food industry applications.

Key topics and requirements

• Definition and classification of ceresin grades (marks 65, 70, 75, 80, 80э) and their intended applications.
• Physical‑chemical requirements: appearance, softening/drop point, flash/ignition characteristics, limits for moisture, ash and impurities, solubility and acid/alkaline numbers where applicable.
• Safety requirements for handling and workplace ventilation; fire safety notes (high boiling point, high flash point, avoid open flame).
• Acceptance rules, sampling and test methods referenced to other GOSTs and normative documents.
• Packaging, marking, transportation and storage provisions (manufacturer packaging, typical warranty storage period: two years under recommended conditions).

Typical use and users

Manufacturers and quality laboratories in the petrochemical, lubricant, polymer and electrical/electronic industries; formulators of wax blends, insulating compounds, adhesives, coatings and specialty greases; procurement and regulatory compliance teams that need to verify material conformity with Russian/Soviet standards. Process and safety engineers consult the standard for handling and storage guidance.

Related standards

Typical normative references and related documents include earlier and neighboring standards on paraffins, waxes and petroleum product testing — for example the earlier edition GOST 2488-73 (replaced), and other GOSTs referenced for test methods and packaging (examples: GOST 2477, GOST 1510 and multiple standards on paraffins and bituminous materials). The standard is often published together in collections covering paraffins, ceresins and related petroleum products.

FAQ

Q: What is this standard?

A: GOST 2488-79 is a Soviet/Russian standard titled "Ceresin. Specifications" that defines technical requirements, grades and testing/handling for industrial ceresin.

Q: What does it cover?

A: It covers the composition and required physical‑chemical properties of ceresin, grading by softening/drop point, safety and workplace requirements, sampling and test methods, and rules for packaging, marking, transportation and storage. It excludes ceresin for food use.

Q: Who typically uses it?

A: Producers of ceresin and paraffin products, laboratories testing petroleum waxes, formulators of lubricants and wax blends, quality assurance and procurement specialists, and engineers responsible for safe handling and storage of wax materials.

Q: Is it current or superseded?

A: The standard GOST 2488-79 remains listed as an active/in‑force standard in Russian/Gost registries; its limitation of validity was lifted by an interstate protocol and the text has recorded amendments (notably in the 1980s and 1990). Users should check the latest consolidated text or national registry for any more recent replacements or national adaptations.

Q: Is it part of a series?

A: Yes — it belongs to the group of standards covering paraffins, ceresins, bitumens and related petroleum wax products and refers to multiple other GOSTs for test methods, packaging and related topics. It replaces an earlier 1973 edition (GOST 2488-73).

Q: What are the key keywords?

A: Ceresin; technical specifications; wax grades 65–80; mineral wax; paraffin products; testing and storage; GOST 2488-79.
