GOST 18180-72 PDF

Full title and description

GOST 18180-72 — Petroleum bitumens. Method for determination of mass change after heating. This interstate (GOST) test method specifies the procedure, apparatus and reporting required to determine the change in mass of petroleum bitumens that occurs during heating (loss due to evaporation of volatile components or gain due to oxidation) and is used to assess heat/ storage stability and short‑term ageing behaviour of bituminous binders.

Abstract

GOST 18180-72 defines a laboratory procedure to measure the change in mass of petroleum bitumens after a controlled heating (conditioning) treatment. The method covers sample preparation, required apparatus, heating conditions, conditioning time, mass measurement, calculation of mass change (expressed as percentage) and reporting. The result helps evaluate the tendency of bitumen to lose volatiles or to oxidize when exposed to elevated temperature for a fixed period and so is used in quality control and formulation of road and roofing bitumens.

General information

• Status: In force (GOST / interstate standard).
• Publication date: Introduced 01 January 1974 (approved 20 October 1972; designation year 1972).
• Publisher: Originally Gosstandart (USSR State Committee for Standards); modern reprints published by Standartinform / national standards bodies.
• ICS / categories: ICS 75.140 (Petroleum and related technologies); OKSTU/OKP classification for oil bitumens.
• Edition / version: GOST 18180-72 (original 1972/1974); reissued editions include amendments No.1, No.2 and No.3 (late 1970s–1980s) and later reprints (e.g., Standartinform edition).
• Number of pages: 2–4 pages depending on edition and publisher.

Scope

The standard applies to petroleum bitumens and establishes a standardized laboratory method to determine the change in mass after a prescribed heating (conditioning) treatment. It is intended for use where assessment of storage/heat stability or short‑term thermal ageing of bituminous binders is required (quality control, specification verification, comparison of product batches and evaluation of modified bitumens).

Key topics and requirements

• Definition of the phenomenon measured: mass loss by evaporation of volatiles or mass gain by oxidation during heating.
• Required apparatus and glassware for accurate mass measurement and controlled heating/oven conditions.
• Sample preparation: sample size, container type and handling prior to heating.
• Prescribed heating/conditioning procedure (temperature, time and atmosphere) and any sample rotation or thin‑film preparation if specified.
• Mass measurement procedure before and after heating and calculation of mass change (absolute and percentage values).
• Reporting format and expression of results, plus notes on repeatability and interpretation (use in stability/ageing assessment).
• Application notes: how positive or negative mass change should be interpreted (evaporation vs. oxidative uptake) and use of the result in acceptance criteria or comparative testing.

Typical use and users

Laboratories in bitumen production and refining, quality control/assurance departments of manufacturers and suppliers of road, roofing and construction bitumens, materials testing laboratories, research organisations studying ageing and storage stability of binders, and regulatory/standards bodies. Typical uses include batch acceptance testing, formulation checks for modified bitumens, investigation of storage behaviour and comparative evaluation of thermal/oxidative susceptibility.

Related standards

Commonly referenced or complementary standards include national and international bitumen testing methods and specifications such as GOST standards for road and roofing bitumens (for example, related GOSTs covering penetration, softening point and other quality tests), and international equivalents for heat/ageing tests, notably ASTM D2872 (RTFOT — Rolling Thin Film Oven Test), EN/ISO test methods for ageing (e.g., EN 12607 series/RTFOT, TFOT) and other regional bitumen specifications used for comparative assessment.

FAQ

Q: What is this standard?

A: GOST 18180-72 is a GOST (interstate) standard that specifies a laboratory method to determine the change in mass of petroleum bitumens after a defined heating (conditioning) treatment.

Q: What does it cover?

A: It covers apparatus, sample preparation, a prescribed heating/conditioning procedure, mass measurement before and after heating, calculation of mass change and reporting — used to detect loss of volatiles or mass increase from oxidation during heating.

Q: Who typically uses it?

A: Bitumen producers, QC/QA laboratories, construction materials laboratories, research organisations and standards/regulatory bodies involved in assessment of bitumen properties and stability.

Q: Is it current or superseded?

A: Historically introduced in 1974 (designation year 1972) and maintained with amendments. It is generally treated as an active/test method standard in databases and reprints; users should check the current status with their national standards body or the latest standards catalogue for any national replacements or newer test methods before use.

Q: Is it part of a series?

A: It is one of several GOST/industry standards dealing with petroleum bitumens and their testing (penetration, softening point, TFOT/RTFOT ageing tests, etc.). It is commonly used alongside other bitumen standards for a complete quality/ageing assessment.

Q: What are the key keywords?

A: Petroleum bitumen, mass change after heating, loss on heating, oxidation, storage stability, thermal ageing, test method, GOST 18180-72.
