The latest, up-to-date edition.
Available Superseded
An Available Superseded Standard is one, which has been made available for a period of time although it has been formally superseded by another Standard. Its availability is maintained where it is referenced in legislation/regulations
or in other Standards and its use should be restricted to where so referenced. No responsibility is taken by SAI Global as to the ongoing technical validity of such a Standard, the responsibility resting with the referencing authority.
Superseded
A superseded Standard is one, which is fully replaced by another Standard, which is a new edition of the same Standard.
Withdrawn
A Withdrawn Standard is one, which is removed from sale, and its unique number can no longer be used. The Standard can be withdrawn and not replaced, or it can be withdrawn and replaced by a Standard with a different number.
Lapsed
A document that is past its comment period, but has not been superseded and where it is unlikely the project or product will go ahead.
Obsolescent
“Obsolescent” indicates that the Standard is not recommended for new equipment or as a current practice, but it is retained in order to provide for servicing of existing equipment or requirements.
Redesignated
A redesignated Standard is one that has had its number changed. This could be the main number, the part number or the sub-part number.
Terminated
A document that has not been superseded, but where the project or product is no longer required.
