39、 is responsible for the preparation and maintenance of the product description. This description shall describe the product and/or product families. Disclosure of the product description shall be at the discretion of the chemically strengthened glass manufacturer or his agent except in the case of r
40、egulatory requirements. The description shall contain at least a normative part. The description may also contain an informative part, when the manufacturer foresees further development of the product. The normative part of the description shall contain the following minimum information: - a referen
