Full title and description

Surface-active agents — Determination of water content — Karl Fischer method. This entry describes the original ISO 4317 first edition published in 1977, which specifies a Karl Fischer titration procedure for measuring water content in surface-active agents and detergents.

Abstract

The 1977 edition of ISO 4317 sets out a Karl Fischer method for determination of water content in surface-active agents and detergents. The first edition (1977) was later withdrawn and revised by subsequent editions; later editions expand and update methodology and scope.

General information

• Status: Withdrawn / superseded.
• Publication date: August 1977 (first edition).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 71.100.40 (Surface-active agents).
• Edition / version: Edition 1 (1977).
• Number of pages: 3 pages (first edition).

Scope

Specifies a Karl Fischer titration procedure for determining the water content of surface-active agents and detergents. The method as published in 1977 applies to products for which this approach is appropriate; later editions revise and extend the methods and application guidance.

Key topics and requirements

• Use of Karl Fischer reagent for moisture determination in surfactants and detergents.
• Sample types covered (surface-active agents and detergent formulations) and applicability conditions.
• Requirement to consider interfering substances (addressed in later revisions).
• Traceable analytical procedure intended for quality control and specification purposes.

Typical use and users

Laboratories performing quality control and acceptance testing of surface-active agents and detergent products, manufacturers of surfactants and detergents, analytical chemists, and standards bodies referencing moisture-determination procedures in product specifications. Users typically apply the method to powders, pastes and solutions when the standard indicates Karl Fischer analysis is appropriate (later editions provide broader methodological options).

Related standards

This first edition was later revised and replaced by ISO 4317:1991 and subsequently by ISO 4317:2011, which provide updated Karl Fischer methods (volumetric and coulometric) and expanded guidance. Other ISO standards in the same ICS family (e.g., standards addressing detergent performance and titrimetric determinations) may be relevant for complementary tests.

FAQ

Q: What is this standard?

A: ISO 4317:1977 is the first-edition international standard titled "Surface-active agents — Determination of water content — Karl Fischer method," specifying a Karl Fischer titration procedure for moisture determination in surfactants and detergents.

Q: What does it cover?

A: It covers a Karl Fischer titration method for measuring water content in surface-active agents and detergents and gives requirements for applying that analytical technique where appropriate. Later editions update methodology and applicability.

Q: Who typically uses it?

A: Quality-control and analytical laboratories, manufacturers of surfactants and detergents, formulation chemists, and standards organizations that reference moisture-determination methods.

Q: Is it current or superseded?

A: ISO 4317:1977 has been withdrawn and superseded by later editions (notably ISO 4317:1991 and ISO 4317:2011). Users should refer to the most recent edition for current methods and requirements.

Q: Is it part of a series?

A: It belongs to the body of ISO standards on surface-active agents (ISO/TC 91 work) and has been revised in later ISO 4317 editions; related standards in the same ICS address other analytical methods and performance tests for detergents and surfactants.

Q: What are the key keywords?

A: Surface-active agents, detergents, water content, Karl Fischer, moisture analysis, titration, ISO 4317.
