General notes:
Standards in the BS 5775 series have been withdrawn as their international equivalents in the ISO 31 series were amended in 1998: these amendments have been endorsed as suitable for use in the UK. Although ISO 31-11:1992 was $7Inot$7R amended, this standard is also being withdrawn in order to elimate confusion.
