Comprehensive Guide to EN 14997 Leaching Behavior Assessment Laboratory Testing Service

Provided by Eurolab

Standard-Related Information

EN 14997 Leaching Behavior Assessment is a laboratory testing service that evaluates the potential leaching behavior of materials under various environmental conditions. This standard is part of the European Standard (EN) series, which is maintained and published by CEN (European Committee for Standardization).

Relevant Standards

Standard Development Organizations

The standard development process involves multiple stakeholders, including:

1. CEN (European Committee for Standardization)

2. ISO (International Organization for Standardization)

3. ASTM (American Society for Testing and Materials)

4. TSE (Turkish Standards Institution)

These organizations collaborate to develop and maintain standards that meet the needs of industries and countries worldwide.

Evolution of Standards

Standards evolve as technology advances, new research emerges, or regulatory requirements change. This is why its essential to regularly review and update standards to ensure they remain relevant and effective.

Standard Numbers and Scope

EN 14997:2018 covers the leaching behavior of construction products and building materials under various environmental conditions. The standard specifies testing methods for determining the potential leaching behavior of materials, including:

1. pH-dependent leaching

2. Neutral salt solution (NSS) leaching

3. Acetic acid/sodium acetate buffer (A/SAB) leaching

Standard Compliance Requirements

Compliance with EN 14997:2018 is mandatory for construction products and building materials in the European Union, Turkey, and other countries that adopt this standard.

Industries that require compliance include:

1. Construction

2. Building materials manufacturing

3. Chemicals and coatings production

4. Wastewater treatment

Standard-Related Costs

The cost of testing and certification can vary depending on factors such as sample size, testing parameters, and laboratory equipment. However, complying with EN 14997:2018 is essential to ensure product safety and regulatory compliance.
