Full title and description

ISO 1695:1977 — o‑Chlorotoluene for industrial use — List of methods of test. Provides standardized test and sampling methods for o‑chlorotoluene (2‑chlorotoluene) intended for industrial use.

Abstract

This International Standard specifies sampling procedures and a short set of physical and analytical test methods for o‑chlorotoluene: determination of distillation characteristics, density at 20 °C, crystallizing point and the determination of p‑ and o‑chlorotoluene content. It replaced ISO Recommendation R 1695‑1970 when published in 1977.

General information

• Status: Withdrawn.
• Publication date: February 1977 (first edition).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 71.080.20 (Chemical products — Organic compounds).
• Edition / version: Edition 1 (ISO 1695:1977).
• Number of pages: 4 pages.

Scope

Defines methods of test applicable to o‑chlorotoluene intended for industrial use, including procedures for obtaining laboratory samples, measuring distillation characteristics and density, determining crystallizing (freezing) point and identifying/quantifying p‑ and o‑chlorotoluene content. The standard formalized and replaced the earlier ISO Recommendation R 1695‑1970.

Key topics and requirements

• Sampling of bulk and laboratory samples (references to ISO 2209 sampling methods).
• Determination of distillation characteristics (method based on ISO/R 918 with specified volumes V0 and V1).
• Density measurement at 20 °C (reference to ISO 758 pyknometer/density methods).
• Determination of crystallizing (freezing) point with specified thermometer range and sample drying procedures (references to ISO 1392).
• Identification and quantification of p‑ and o‑chlorotoluene content (procedures using crystallizing‑point tables/diagrams and analytical separation where appropriate).
• Requirements for sample preparation (drying agents, thermometer calibration/type) and reporting of test results.

Typical use and users

Used historically by chemical manufacturers, quality control and analytical laboratories, distributors of solvent‑grade halogenated aromatics, and regulatory/testing bodies to specify and perform routine quality tests on o‑chlorotoluene consignments. Because the standard is withdrawn, laboratories now rely on current national methods or updated ISO/industry test methods where available.

Related standards

Related documents and cross‑references include ISO Recommendation R 1695‑1970 (predecessor), the companion ISO items in the same series (ISO 1696, 1697, 1698, 1699 dealing with related chlorinated toluenes/benzene products), and referenced test methods such as ISO 758 (density at 20 °C), ISO 2209 (sampling of liquid halogenated hydrocarbons) and ISO 1392 (crystallizing point). The standard was prepared under ISO/TC 47 (Chemistry).

FAQ

Q: What is this standard?

A: ISO 1695:1977 is an International Standard that specified a concise set of test and sampling methods for o‑chlorotoluene intended for industrial use.

Q: What does it cover?

A: It covers sampling, measurement of distillation characteristics, density at 20 °C, crystallizing point and determination of p‑ and o‑chlorotoluene content, with references to established ISO test methods for each determination.

Q: Who typically uses it?

A: Chemical producers, QC/analytical laboratories, product distributors and regulatory/testing organizations concerned with the quality and identity of industrial solvent‑grade o‑chlorotoluene.

Q: Is it current or superseded?

A: ISO 1695:1977 has been withdrawn. Available catalogue records indicate the International Standard is withdrawn (no direct replacement is listed in the ISO catalogue); some national catalogues show the withdrawal recorded (example: withdrawn in national listings by 2002). Users should consult current ISO catalogue entries or national standards bodies for any newer or replacement methods.

Q: Is it part of a series?

A: Yes — it belongs to a group of ISO documents addressing analytical and test methods for chlorinated aromatic solvents (ISO 1696–1699 and related items) and references a number of general test method standards (ISO 758, ISO 2209, ISO 1392).

Q: What are the key keywords?

A: o‑chlorotoluene, 2‑chlorotoluene, chlorotoluene, test methods, sampling, density, distillation, crystallizing point, ISO 1695.
