What is BS EN 62321-7-2 - Determination of Hexavalent chromium in electrotechnical products about?
BS EN 62321-7-2 is the second subpart of the seventh part of the multi-series standard that focuses on the determination of certain substances in electrotechnical products.
BS EN 62321-7-2 describes procedures to measure hexavalent chromium, Cr(VI), quantitatively in samples of polymers and electronics. This method employs organic solvent to dissolve or swell the sample matrix, followed by an alkaline digestion procedure to extract Cr(VI) from samples. Studies have shown that an organic/alkaline solution is more effective than an acidic solution in extracting Cr(VI) from soluble and insoluble samples. Minimal reduction of Cr(VI) to Cr(III) or oxidation of Cr(III) to Cr(VI) occurs under alkaline conditions.
Who is BS EN 62321-7-2 - Determination of Hexavalent chromium in electrotechnical products for?
BS EN 62321-7-2 on the determination of Hexavalent chromium in electrotechnical products is useful for:
- Electrotechnical industries 
- Chemical laboratories  
- Chemical and environmental scientists  
- Environmental regulatory bodies 
- Manufacturers and suppliers of electrotechnical products and polymers
Why should you use BS EN 62321-7-2 - Determination of Hexavalent chromium in electrotechnical products?
The widespread use of electrotechnical products has drawn increased attention to their impact on the environment. In many countries all over the world this has resulted in the adaptation of regulations affecting wastes, substances and energy use of electrotechnical products. The use of hexavalent chromium in electrotechnical products is of concern in many regions of the world.
BS EN 62321-7-2 provides you with the procedures like extraction of Cr(VI) insoluble polymers – ABS, PC and PVC matrixes and Extraction of Cr(VI) in insoluble/unknown polymers and electronics − without Sb this will help you to analyse hexavalent chromium in batches of not more than 20.
You can use BS EN 62321-7-2 to determine the levels of hexavalent chromium in electrotechnical products on a consistent global basis.
WARNING – Persons using BS EN 62321-7-2 should be familiar with normal laboratory practice.
What’s changed since the last update?
BS EN 62321-7-2:2017 supersedes BS EN 62321:2009, which is withdrawn.
