BS 3828:1973

This standard BS 3828:1973 Specification for crystal glass is classified in these ICS categories:

• 81.040.10 Raw materials and raw glass

This British Standard specifies requirements for chemical composition and physical properties of categories of glass used in the manufacture of crystal glassware, together with appropriate test methods and marking provisions.

Section 1 specifies four categories of glass, as defined in the corresponding Directive of the Council of the Economic Communities.

Section 2 specifies additional requirements relating to only two of these categories of glass.

NOTE The title of the British Standard referred to in Section 2 of this standard is given on page 8.

Section 1 covers 4 categories of glass, is technically identical with the EEC Directive on crystal glass and is intended for reference in the statutory instrument which will implement this Directive in the UK. Section 2 incorporates certain requirements additional to those in the EEC Directive for the two higher categories of glass, and in effect maintains the superior qualities of glasses of UK manufacture complying with the previous edition.
