Overview

ISO 1686:1976 Sodium and potassium silicates for industrial use - Samples and methods of test - General is an internationally recognized standard developed by ISO. Its primary purpose is to provide general procedures for the sampling and testing of sodium and potassium silicates intended for industrial applications. The standard outlines best practices for sample preparation, handling, and analysis to ensure the reliability and consistency of test results. It is applicable to silicates in solution or those that are soluble in boiling water. For solid materials not readily soluble in boiling water, the standard requires specific preliminary treatments. Special attention is given to avoiding moisture and carbon dioxide absorption, as these can affect sample integrity and accuracy of analytical results.

Key Topics

Scope of application: Focuses on sodium and potassium silicates for industrial use, especially those that are soluble or can be dissolved for analysis.

Sample preparation: Emphasizes techniques for handling and storing samples to avoid contamination from moisture or carbon dioxide, particularly for solid chemicals.

Testing conditions: All sampling and analytical processes are to be conducted at approximately 20°C, utilizing only analytical reagent grade chemicals for accurate determinations.

Sample integrity: Precautions to maintain sample purity and guidelines on how to handle materials that are not easily soluble in boiling water, often referencing additional ISO standards.

Representative sampling: Recommends collecting a sample of approximately 750 g for comprehensive testing requirements.

Applications

Adhering to ISO 1686 is essential for various sectors that manufacture or use sodium and potassium silicates, as it ensures:

Quality control in chemical production facilities, where consistent analysis protocols are critical to process reliability.

Industrial compliance with international standards, helping organizations meet customer and regulatory demands.

Accurate chemical analysis for research and development, facilitating reproducibility and trustworthy comparative data in laboratory studies.

Safe handling and preparation of solid and liquid silicates, reducing the risk of error due to improper sampling or environmental contamination.

Seamless integration with related analytical methodologies for specific quality parameters such as density, dry matter, and alkalinity.

This standard supports a wide range of industrial users, including producers of adhesives, detergents, ceramics, and water treatment chemicals, where silicate-based compounds are common.

Related Standards

ISO 1686 operates in conjunction with several other ISO standards designed to ensure thorough and precise evaluation of sodium and potassium silicates. These include:

ISO 1687: Determination of density at 20°C using density hydrometer or pyknometer methods.

ISO 1688: Gravimetric determination of dry matter.

ISO 1689: Calculating the ratio of silica to sodium or potassium oxide.

ISO 1690: Gravimetric determination of silica content by insolubilization.

ISO 1691: Gas-volumetric determination of carbonate content.

ISO 1692: Titrimetric determination of total alkalinity.

ISO 2122: Preparation of solutions from silicates not easily soluble in boiling water and determination of insoluble matter.

ISO 2123: Determination of dynamic viscosity.

ISO 2124: Titrimetric determination of silica content using the barium sulphate gravimetric method.

ISO 3200: Gravimetric determination of sulphate content.

ISO 3201: Photometric determination of iron content.

These related standards support the comprehensive and standardized testing procedures necessary for the industrial use of sodium and potassium silicates, enabling global consistency and high-quality results.
