ISO 1920-8 Determination of Water Absorption of Hardened Concrete Laboratory Testing Service: A Comprehensive Guide

The determination of water absorption of hardened concrete is a critical test for assessing the durability and quality of concrete structures. This article provides an in-depth overview of the relevant standards governing this testing service, including ISO 1920-8.

ISO 1920-8

ISO 1920-8 is an international standard developed by the International Organization for Standardization (ISO) that specifies the method for determining the water absorption of hardened concrete. The standard provides a detailed procedure for measuring the amount of water absorbed by concrete under controlled conditions.

ASTM C1582

The American Society for Testing and Materials (ASTM) has also developed a standard, ASTM C1582, which is equivalent to ISO 1920-8. This standard provides an alternate method for determining the water absorption of hardened concrete using a similar procedure.

EN 12390-7

In Europe, the European Committee for Standardization (CEN) has published a standard, EN 12390-7, which is based on ISO 1920-8 and ASTM C1582. This standard provides a harmonized method for determining the water absorption of hardened concrete in Europe.

TSE 665

In Turkey, the Turkish Standards Institution (TSE) has developed a national standard, TSE 665, which is equivalent to ISO 1920-8. This standard provides a method for determining the water absorption of hardened concrete using a similar procedure.

Standard Development Organizations and Their Role

The development of standards such as ISO 1920-8, ASTM C1582, EN 12390-7, and TSE 665 is led by various standard development organizations (SDOs). These SDOs include:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Standardization (CEN)

  • Turkish Standards Institution (TSE)

    • These SDOs work together to develop and maintain international, national, and regional standards that provide a framework for testing and measurement.

    How Standards Evolve and Get Updated

    Standards are regularly reviewed and updated by SDOs to reflect changes in technology, industry practices, and regulatory requirements. This ensures that the standards remain relevant and effective in supporting innovation, trade, and consumer protection.

    Specific Standard Numbers and Their Scope

    The following table provides an overview of the specific standard numbers and their scope:
