India consults on chemical standards for plastics and resins

The Bureau of Indian Standards (BIS) started a reinvestigation of the use of eight chemical standards in plastics, resins, moulding, and extrusion materials. The standards outline all the procedures, sampling methods, and tests that companies must follow while working with these compounds. 

The standards cover:  

Substance Comment Deadline 
4-nonylphenol May 11 
4-octylphenol (4-tert-octylphenol) May 11 
hexamethyldisilazane May 18 
polyolefin elastomer (POE) May 18 
ethylene-vinyl acetate (EVA) May 18 (part 1), May 8 (part 2) 
Poly (methyl methacrylate) (PMMA) May 18 (part 1), May 8 (part 2) 

  The Indian body also proposed changing some of the requirements, sample techniques, and testing in the following standards: 

Standards Comment Deadline 
Polycarbonate moulding and extrusion materials May 21 
2018 positive list of colourants in FCMs June 19 
Polyalkylene terephthalate (PET and PBT), their copolymers and the list of constituents in raw materials and end products in FCMs May 20 
Styrene (vinyl benzene) June 17
