SIST EN ISO 11890-2:2020/A1:2024 PDF

Overview

SIST EN ISO 11890-2:2020/A1:2024 is an important amendment to the European and international standard for the determination of volatile organic compounds (VOC) and semi-volatile organic compounds (SVOC) content in paints and varnishes. This document updates the gas-chromatographic method described in Part 2 of ISO 11890-2:2020, incorporating key changes approved by CEN in 2024. It serves as a critical reference for laboratories and manufacturers aiming to accurately quantify VOC and SVOC levels, ensuring compliance with environmental regulations and product quality standards.

Key Topics

• Gas Chromatographic Analysis The amendment refines procedures for gas chromatographic determination of VOCs and SVOCs, focusing on sample injection, oven temperature programming, and detection parameters to improve accuracy and reproducibility.

• Water Content Determination Incorporates relevant references to ISO 23168 alongside ISO 760 for determining water content in paint samples, emphasizing reagent selection to avoid analytical interference. Accurate water content measurement is essential as it affects VOC calculations.

• Updated Analytical Conditions The document provides a new example of gas chromatographic conditions, including injector temperature (250 °C), split ratio (1:40), and specific oven temperature programs, improving method robustness for different sample compositions.

• Chemical Substances Updates Amendments include updates to chemical substance data tables, such as revised properties for Lauryl alcohol and Linalyl acetate, supporting better identification and quantification during chromatographic analysis.

• International Collaboration Developed through collaboration between ISO Technical Committee ISO/TC 35 and CEN Technical Committee CEN/TC 139, this amendment adheres to the Vienna Agreement ensuring harmonized standards across Europe and internationally.

Applications

• Quality Control in Paint Manufacturing Enables manufacturers to monitor VOC and SVOC content in their products, maintaining compliance with environmental and safety regulations while ensuring product performance and consistency.

• Environmental Compliance Testing Assists regulatory bodies and laboratories in verifying VOC emissions from paints and varnishes, contributing to air quality protection and adherence to volatile organic compound emission standards.

• Material Safety Evaluation Supports safety data sheet (SDS) preparation by providing reliable VOC and SVOC content data, essential for risk assessments and handling procedures in various industries using paints.

• Research and Development Facilitates formulation development by providing precise analytical data on solvent content, helping chemists optimize paint formulations for low VOC emissions and improved durability.

Related Standards

• EN ISO 11890-1 Covers determination of VOC and SVOC content by evaporation method, complementing the gas-chromatographic approach in Part 2.

• ISO 23168 Specifies the gas-chromatographic method for determining water content in paints and varnishes, referenced for accurate moisture analysis within the amended standard.

• ISO 760 Describes the Karl Fischer titration method for water content determination, also acknowledged as suitable for integration depending on sample characteristics.

• CEN/CENELEC Internal Regulations Framework governing implementation of CEN standards and amendments across national bodies, ensuring uniform adoption of SIST EN ISO 11890-2:2020/A1:2024.

This amendment to EN ISO 11890-2:2020 enhances the precision and scope of VOC and SVOC content determination in paints and varnishes using gas chromatography. It supports industry stakeholders in meeting stringent environmental standards and improving product safety and quality through standardized laboratory methods.
