Full title and description
St ISO 1394-1977 rus — ISO 1394:1977 "Liquid halogenated hydrocarbons for industrial use — Determination of cloud point". Specifies a simple laboratory method for detecting impurities (primarily dissolved water) by determining the temperature at which a clear sample becomes cloudy when gradually cooled under specified conditions.
Abstract
This short international standard (edition 1, 1977) defines the principle and basic procedure to determine the cloud point of liquid halogenated hydrocarbons used in industry. The test detects cloudiness caused by dissolved impurities (generally water) by recording the temperature at which cloudiness first appears during controlled cooling. The standard replaces ISO Recommendation R 1394-1970.
General information
- Status: Withdrawn (ISO lifecycle: withdrawn/obsolete).
- Publication date: February 1977 (ISO publication: 1977-02).
- Publisher: International Organization for Standardization (ISO).
- ICS / categories: 71.080.20 (chemistry — halogenated hydrocarbons / related test methods).
- Edition / version: Edition 1 (1977).
- Number of pages: 2 pages (concise procedural standard).
Scope
Provides a simple, rapid test method to determine the cloud point of liquid halogenated hydrocarbons for industrial use. The method is intended to reveal the presence of certain impurities (chiefly water) that cause clouding on cooling and to record the temperature at which cloudiness first appears under specified cooling conditions. The standard is brief and focused on the detection principle rather than extensive apparatus detail.
Key topics and requirements
- Definition of the cloud point for liquid halogenated hydrocarbons (appearance of cloudiness on cooling).
- Principle: gradual cooling of a clear sample and observation of the temperature at initial cloud formation.
- Sample handling and test conditions sufficient for reproducible detection of dissolved-water-type impurities.
- Simple, rapid procedure suitable for routine quality checks in manufacturing or incoming inspection.
- Reference/relationship to the earlier ISO Recommendation R 1394-1970 (standard replaces that recommendation).
Typical use and users
Used by chemical quality-control laboratories, manufacturers and suppliers of liquid halogenated hydrocarbons, industrial testing laboratories, and regulatory or conformity-assessment bodies that require a quick check for water/impurity-related clouding. Also of interest to standards libraries and translators seeking Russian-language copies of historical ISO documents.
Related standards
ISO 1394:1977 is part of ISO's body of work on halogenated hydrocarbons and related test methods. It replaces ISO Recommendation R 1394-1970 and sits alongside other ISO standards addressing sampling and analytical methods for halogenated hydrocarbons (examples in the same topic area include ISO 2209 and ISO 3427 — see collections of related ISO chemical-method standards).

FAQ
Q: What is this standard?
A: ISO 1394:1977 is an international standard titled "Liquid halogenated hydrocarbons for industrial use — Determination of cloud point" that defines a simple test to detect cloudiness caused by certain dissolved impurities when a sample is cooled.
Q: What does it cover?
A: It covers the principle and basic procedure for determining the temperature at which a clear sample of liquid halogenated hydrocarbons first becomes cloudy on controlled cooling — primarily to reveal dissolved water or similar impurities.
Q: Who typically uses it?
A: Chemical manufacturers and suppliers of halogenated hydrocarbons, testing and QC laboratories, standards organizations, and purchasers of industrial solvents who need a quick impurity-detection test.
Q: Is it current or superseded?
A: The ISO record shows ISO 1394:1977 as withdrawn. Users requiring an up-to-date normative test should consult current ISO catalogues or national standards bodies for any replacement or alternative methods.
Q: Is it part of a series?
A: It replaces an earlier ISO Recommendation (R 1394-1970) and is part of ISO's broader set of standards and recommendations dealing with halogenated hydrocarbons and their analytical/testing methods. Related ISO test-methods cover sampling and other analytical procedures for halogenated compounds.
