ISO 10238-1999 rus PDF

Full title and description

ISO 10238:1999 — Carbonaceous materials used in the production of aluminium — Pitch for electrodes — Determination of sulfur content by an instrumental method. This International Standard specifies an instrumental test procedure for measuring the sulfur content of pitches used to produce aluminium electrodes (applicable to pitches of coal‑tar and petroleum origin, in the range ~0.1 % to 4.0 % by mass).

Abstract

This standard describes an instrumental method for determination of sulfur in electrode pitch. It is intended for pitches of both coal‑tar and petroleum origin that contain between 0.1 % and 4.0 % sulfur by mass. The document lists relevant normative references and sample preparation requirements.

Scope

ISO 10238:1999 defines an instrumental laboratory method for determining sulfur in pitch intended for electrodes used in aluminium production. The method is applicable to pitches of coal‑tar and petroleum origin whose sulfur mass fraction lies between approximately 0.1 % and 4.0 %. Normative references (sampling, laboratory water, sieves and filters) are cited in the standard to ensure consistent sample preparation and test conditions.

Key topics and requirements

• Instrumental determination of sulfur in electrode pitch (method principle and apparatus specified in the body of the standard).
• Applicability limited to pitches of coal‑tar and petroleum origin with sulfur content ≈0.1–4.0 % by mass.
• Normative references and sample‑handling requirements (e.g., ISO 565, ISO 3696, ISO 4793, ISO 6257 are referenced).
• Requirements intended to support quality control and material specification for aluminium‑industry carbonaceous materials (precision and repeatability statements appear in the normative text).

Typical use and users

Primary users are quality control laboratories, production technologists and materials engineers in the aluminium and carbon‑product industries, test houses and accreditation bodies that perform chemical analysis of pitch for electrodes. Laboratories implementing ISO 10238 commonly also follow related ISO methods and national adoptions when preparing samples and reporting results.

Related standards

Related ISO and national documents include ISO 6257 (sampling of pitch for electrodes), ISO 565, ISO 3696 and ISO 4793 (laboratory consumables and water), and other ISO standards for carbonaceous materials used in aluminium production (examples: ISO 14435, ISO 11412, ISO 8658). A Russian national adoption/translation has been published under the designation GOST R ISO 10238‑2015 (published 2016) which represents a national version of the ISO method; however the ISO central publication itself is English.
