This is a republication of the Boilers and Pressure Vessels Regulations 1954 as in force under the Machinery Act 1949 on 30 November 2000.  It includes all amendments made to the regulations up to Subordinate Law 2000 No 47.
Amending laws are annotated in the table of legislation and table of amendments.
The Parliamentary Counsel’s Office currently prepares 2 kinds of republications of ACT laws:  authorised printed republications to which the Legislation (Republication) Act 1996 applies and unauthorised electronic republications.  The status of a republication appears on its cover and from its republication number.
A republication number without a letter (eg 1, 2, 3 etc) indicates that the republication is an authorised printed republication.  A number with a letter (eg 1A, 1B, 1C etc) indicates that the republication is an unauthorised electronic republication.
Section 13 of the Legislation (Republication) Act 1996 authorises the Parliamentary Counsel, in preparing a law for republication, to make textual amendments of a formal nature which the Parliamentary Counsel considers desirable in accordance with current legislative drafting practice.  The amendments do not effect a substantive change in the law.
In preparing this republication, amendments have not been made under section 13.
Not all amendments made under section 13 are annotated in the table of amendments.  Full details of any amendments can be obtained from the Parliamentary Counsel’s Office.
