With numbered articles, there is no hierarchical relationship, let alone any connection regarding the content.
2.2.1.8 Lower the standards as a special case. 2.2.1.2.1 is the general requirement.
Clause 2.2.1.2.1 sets out the general requirements for pressure vessels, while clause 2.2.1.8 specifies the specific requirements; in cases where no specific requirements are given, the general requirements must be complied with
There is no hierarchical relationship, and the requirements for steel used in simple pressure vessels have been relaxed somewhat.
Clause 2.2.1.2.1 sets out the general requirements for pressure vessels, while clause 2.2.1.8 specifies the specific requirements; in cases where there are such specific requirements, they shall be followed
