EN ISO 182-1 Plastics, Vinyl Chloride Homopolymers and Copolymers, Trends of Compounds to Develop Hydrogen Chloride and Other Acidic Products at High Temperatures

EUROLAB laboratory provides testing and compliance services within the scope of EN ISO 182-1 standard. It was designed primarily as a simple and rapid quality control test during the manufacture and conversion of PVC compounds. Suitable for colored compounds.

Not recommended for compounds in the form of dry mixes. The determination is carried out on a sample of PVC compound held at an agreed temperature in still air until the color of the Congo red paper held on it changes from red to blue.

If universal indicator paper is used, the color change corresponds to pH 3. The time required for color change is taken as the stability time, ts.

The method is only recommended for composite materials and products. For compounds in the form of dry mixes, such materials are not recommended as they may not be sufficiently homogeneous.

PVC compounds and products can develop decomposition products in addition to hydrogen chloride at high temperatures. The limited availability of these degradation products can affect the color change time of the indicator Paper. It is not possible to compensate for this effect under this part of EN ISO 182 and therefore care must be taken when comparing results for different compounds and products.

EUROLAB assists manufacturers with EN ISO 182-1 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
