Full title and description

St ISO 2496-1973 (rus) — Sec‑butyl alcohol for industrial use — List of methods of test. Russian-language edition/translation of ISO 2496:1973 giving standardized test methods and sampling instructions for sec‑butyl alcohol (butan‑2‑ol) intended for industrial applications.

Abstract

This standard specifies sampling and a short list of analytical test methods for sec‑butyl alcohol (butan‑2‑ol) used in industry. It covers procedures for determining distillation characteristics, residue on evaporation, acidity (to phenolphthalein), and colour (Hazen units), and gives requirements for sample storage and handling prior to testing.

Scope

Defines sampling and a concise set of test methods for the quality control of sec‑butyl alcohol (butan‑2‑ol) supplied for industrial use. The standard addresses how to collect and store samples and prescribes laboratory procedures for determining key quality indicators: distillation behaviour, residue on evaporation, acidity (phenolphthalein end‑point) and colour measured in Hazen units. It is intended for routine quality assessment rather than exhaustive characterization.

Key topics and requirements

• Sampling procedure and recommended sample container (dark, glass‑stoppered bottle nearly filled by the sample)
• Determination of distillation characteristics (distillation range / behaviour)
• Measurement of residue on evaporation (expressed as mass remaining after evaporation)
• Determination of acidity to phenolphthalein (acid‑base titration endpoint)
• Measurement of colour in Hazen units (APHA/Hazen scale)
• Short format test methods intended for industrial QC rather than exhaustive analytical characterization

Typical use and users

Used by chemical manufacturers, quality control laboratories, procurement and inspection departments, chemical distributors and testing laboratories that handle or verify the quality of sec‑butyl alcohol (butan‑2‑ol) for industrial applications. Also relevant to standards translators and national bodies maintaining Russian translations of ISO standards.

Related standards

Related documents include other ISO standards and national standards that specify test methods for industrial alcohols and similar organic chemicals, and standards published by ISO technical committee(s) responsible for organic chemical testing (ISO/TC 47). For current methods and any successor standards consult the ISO catalogue or national standards bodies for up‑to‑date replacements or consolidated test method standards.

FAQ

Q: What is this standard?

A: It is the Russian‑language edition/translation of ISO 2496:1973, titled "Sec‑butyl alcohol for industrial use — List of methods of test", which lists short, standardized test procedures and sampling instructions for sec‑butyl alcohol.

Q: What does it cover?

A: Sampling and storage of sec‑butyl alcohol samples and four principal test areas: distillation characteristics, residue on evaporation, acidity (to phenolphthalein) and colour (Hazen units). It sets concise laboratory procedures intended for routine industrial quality control.

Q: Who typically uses it?

A: Chemical producers, QC and analytical laboratories, importers/distributors and procurement or inspection teams responsible for verifying the quality of sec‑butyl alcohol, plus standards translators and national standards bodies maintaining Russian editions.

Q: Is it current or superseded?

A: The original ISO 2496:1973 is withdrawn and is not a current active ISO technical standard. Users requiring up‑to‑date methods should consult the ISO catalogue or their national standards body for any replacement or consolidated methods; no direct, universally adopted successor is implied by the 1973 edition.

Q: Is it part of a series?

A: It forms part of ISO's body of standards addressing test methods for industrial chemicals and falls under the work of ISO technical committee(s) covering organic chemical test methods. It is not a multi‑part series itself but sits alongside other single‑topic ISO test method standards.

Q: What are the key keywords?

A: sec‑butyl alcohol, butan‑2‑ol, sampling, distillation, residue on evaporation, acidity, phenolphthalein, Hazen units, test methods, ISO 2496, Russian edition
