Clause 6.4.1 of GB9948-2013 requires that steel pipes with an outer diameter of not less than 70 mm and a wall thickness of not less than 14 mm shall undergo impact testing. Clause 5.1.4(b) of GB/T150.2-2011 requires that steel pipes with an outer diameter of not less than 70 mm and a wall thickness of not less than 6.5 mm shall undergo impact testing. GB/T150.2-2011, in Clause 2 on normative references, requires that for any reference document without a specified date, its latest version shall apply to this document. How should this sentence be understood? Does this mean that the latest version of the GB9948 standard referenced in GB/T150.2-2011 is applicable to GB/T150.2-2011? In other words, should it be implemented in accordance with GB9948-2013 rather than clause 5.1.4(b) of GB/T150.2-2011? I would like to ask my colleagues: which standard should be followed?

If the design standard for the container in question is GB/T150, then it is necessary to comply with the provisions of GB/T150; if there is no GB/T150 as a design standard, then the applicable design standard should be followed.
Generally, national standards represent the minimum requirements, and industry standards as well as corporate standards cannot surpass these national standards.
Learn* it a bit; I think it should follow GB150.
