What is BS EN ISO 11890-1:2010?

BS EN ISO 11890-1:2010 is a technical standard that focuses on the determination of VOC (volatile organic compounds) content in coatings, varnishes, and raw materials used for their production. This standard provides guidance on sample preparation, testing methods, and calculation of the VOC content.

Why is VOC content important?

Volatile organic compounds are carbon-containing chemicals that easily evaporate into the air at room temperature. They can be found in many commonly used products, including paints, adhesives, and cleaning agents. High levels of VOC emissions have been linked to various environmental and health concerns, such as air pollution and respiratory problems. Therefore, measuring and controlling VOC content is crucial for ensuring product safety and environmental sustainability.

Sample preparation and testing methods

To determine the VOC content in coatings and varnishes as per BS EN ISO 11890-1:2010, specific sample preparation and testing methods need to be followed. First, a representative sample of the coating or varnish is taken. The sample is weighed accurately, and its water and non-volatile content are determined through heating and weighing processes. The difference between the initial weight and the weight after heating gives the volatile content.

The volatile content is then analyzed using gas chromatography (GC), which separates the different volatile compounds present in the sample. The separated compounds are detected and quantified, allowing the calculation of the total VOC content. The use of GC ensures accurate and reliable measurements of VOCs in accordance with the requirements specified in BS EN ISO 11890-1:2010.

Calculation of VOC content

Once the volatile content has been determined, the VOC content is calculated based on the weight of the coating or varnish. The calculation is expressed as a percentage of the weight of VOCs to the total weight of the sample. This value provides an indication of the level of volatile organic compounds emitted by the product and helps manufacturers comply with environmental regulations and guidelines.

BS EN ISO 11890-1:2010 provides detailed instructions on the calculation method, ensuring consistency and accuracy in determining VOC content across different laboratories and testing facilities.

In conclusion, BS EN ISO 11890-1:2010 plays a significant role in the coating and varnish industry by providing a standardized approach for measuring and controlling VOC content. It allows manufacturers to meet regulatory requirements, reduce environmental impact, and ensure the safety and well-being of end-users. Compliance with this technical standard is essential for maintaining high-quality products while also considering the long-term sustainability of our environment.
