Standards for heat exchangers in refrigeration containers
Thread Content
Which is higher, JB/T 4750 or GB-150&GB-151?
In my opinion, GB-150 & GB-151 have high legal validity, as they are after all **mandatory standards**
National standards are higher than industry standards. Posted by yangliudi79 on 2011-7-8 10:11. I think the same way. . But I want to know what the specific differences are?
That’s not a complete statement. It should be that the national standards for \"legal effects\" are higher than the industry standards, while for \"technical requirements\", the industry standards are often higher than the national standards. Regarding JB/T 4750 and GB-150&GB-151, although their requirements differ to some extent, there are no significant differences in terms of theory, methods, or requirements. The specialized containers or heat exchangers used in the refrigeration industry fall outside the scope of GB150 (see 1.3(i)) and GB151 (see 1.4(d)); instead, JB/T4750 should be applied. Of course, it should also fall within the scope governed by JB/T4750. Therefore, it is not appropriate to choose based on the level of a certain standard. Instead, the choice is made based on the actual conditions of the equipment. These are my personal views; please point out any errors if there are any.
