General Requirements, Application of Standard Conditions and Exceptions thereto:

3(1) A boiler shall not be registered under sub-section (4) of Section 7 of the Act and a certificate shall not be issued under sub-section (5) of that section with reference to a boiler, unless the standard conditions in respect of material, design and construction, which are specified in the subsequent Chapters of these Regulations, are satisfied in respect of such a boiler.

(2) Notwithstanding anything contained in sub-regulation (1), the Chief Inspector may, subject to the provisions of regulation 7 and 8, register a boiler and order the issue of a certificate authorising the use thereof, under any of the following circumstances, namely -

(i) when the material used in the construction of a boiler, steam-pipe, economiser or superheater is not in conformity with the Indian Boiler Regulations but is known to be commonly used in other countries as being suitable for use in the construction of boilers and steam-pipes, provided that such material is not specifically prohibited by the Regulation and that the methods of manufacture, fabrication and heat treatment conform to the specified Codes or Standards;
(ii) when the constructional features of a boiler, steam-pipe, economiser or superheater are not in conformity with the Regulations but are not considered by the Chief Inspector to be inferior in strength to those prescribed in the Regulations and form part of the usual manufacturing practice of boilers and steam-pipes in other countries;
(iii) when a boiler, steam-pipe, economiser or superheater has obviously been built in conformity with the regulations but no certificate as required under the regulations is forthcoming.
