Singapore Standards are subject to periodic review to keep abreast of technological changes and new technical developments. The publication of this Singapore Standard is also a strong demonstration of the commitment by professionals in the chemical and supporting industries to set high standards for the continuing development of the chemical industry in Singapore. Companies benefit from over-the-fence selling of products through this linked petroleum and petrochemical cluster concept. 2.
