ISO 4920 Determination of Water Repellency and Its Effect on Dimensional Stability

Determination of Water Repellency and Its Effect on Dimensional Stability: ISO 4920 Testing Services Provided by Eurolab

ISO 4920 is a globally recognized standard that outlines the requirements for determining the water repellency and its effect on dimensional stability of materials. This standard is published by the International Organization for Standardization (ISO) and is widely adopted across various industries, including construction, textiles, and packaging.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ISO 4920 testing services is governed by international and national standards. In the European Union, for example, the EU Regulation No. 305/2011 on Construction Products sets out the requirements for the declaration of performance and the conformity assessment procedures for construction products.

In the United States, the American Society for Testing and Materials (ASTM) publishes similar standards, such as ASTM E96, which covers water vapor transmission through materials. The US Environmental Protection Agency (EPA) also has regulations related to the testing and certification of building materials.

International and National Standards

The following are some key international and national standards that apply to ISO 4920 testing services:

Standard Development Organizations

Standard development organizations, such as the ISO, ASTM, and EN (European Committee for Standardization), play a crucial role in developing and maintaining standards.

The standard development process typically involves:

1. Identifying the need for a new standard or revising an existing one

2. Conducting research and gathering data to develop the standard

3. Drafting the standard

4. Reviewing and approving the standard

Standard Evolution and Updates

Standards are constantly evolving to reflect changes in technology, regulatory requirements, and industry needs.

The ISO 4920 standard, for example, has undergone several revisions since its initial publication in 1987. The most recent revision, ISO 4920:2015, incorporates new testing methods and improves the accuracy of the results.

Standard Compliance Requirements

Compliance with relevant standards is a critical aspect of ensuring product safety and performance.

In the construction industry, for example, compliance with EU Regulation No. 305/2011 on Construction Products requires that products be tested and certified according to ISO 4920.

The following industries and sectors require ISO 4920 testing services:
