What is EN ISO 11890-2:2013

Introduction

EN ISO 11890-2:2013 is a technical standard that provides guidelines and specifications for the determination of water content in paints, varnishes, and related products. It is an essential tool for manufacturers, quality control analysts, and researchers in the coatings industry. This article aims to provide a thorough understanding of this standard and its significance in the industry.

Scope and Purpose

The standard EN ISO 11890-2:2013 specifies a gravimetric method for determining water content in paints, varnishes, and other coating materials. Its main purpose is to ensure accurate measurement of water content, which is crucial for product quality and performance evaluation. By implementing this standard, manufacturers can maintain consistency in their product formulations and guarantee that the water content falls within acceptable limits.

Test Procedure

The test procedure outlined in EN ISO 11890-2:2013 involves weighing a sample of the paint or varnish, heating it at a specific temperature, and then reweighing it to determine the loss in weight, which corresponds to the water content. The standard provides detailed instructions on sample preparation, temperature conditions, and calculation methods to obtain accurate results. It also includes considerations for equipment calibration and validation to ensure reliability and reproducibility of the measurements.

Benefits and Applications

Accurate determination of water content is vital in the coatings industry as it affects various properties of the final product, including viscosity, drying time, and adhesion. By following the guidelines of EN ISO 11890-2:2013, manufacturers can achieve consistent product quality, improve production efficiency, and meet customer requirements. This standard is widely used in laboratories, research institutions, and manufacturing facilities worldwide to ensure the reliability and compatibility of different coating materials.
