All the significant changes introduced are listed in the “Introduction”. The Technical Committee has reviewed the provisions of ISO 3665 to wh

There is no corresponding British Standard for ISO/TR 7405, to which reference is made in the “Introduction” and clause 2 for information only. In the UK it is common practice to as
