Question about "ASME code key words" ?
(OP)
when I was read ASME CODE BOOK usually meet "Shall", "May not", "May can", "shall be".
Some people talks to me read ASME code keywords:
"Shall" is mandatory,
"May not" is prohibition,
"May can" is recommendations/Exemptions from prohibition, and
"shall be" is recommendations
so, I want to ask anyone this is CORRECT?

Check B31.3 applications, refer to para 300.2 Definitions and show it on under:
shall: a term which indicates that a provision is a Code requirement.
should: a term which indicates that a provision is recommended as good practice but is not a Code requirement.
may: a term which indicates that a provision is neither required nor prohibited.

Now, in addition to XL83NL's reference to B31.3, you could review ASME PCC-2 Part 1 paragraph 3.2. Which is a lot shorter than the B31.3 version. The definition for "should" is necessarily slightly different than that from B31.3, the "may" and "shall" definitions are essentially the same.

Share it ..
May: indicates an action that is permitted, but not required.
Shall: an action that is mandatory. It indicates an action that is an essential element of the repair method that cannot be eliminated.
Should: an action that is not mandatory. It indicates an action that when performed, is generally considered to be good practice;
however, there are some circumstances when the action is not appropriate or required, so the word should is used to provide flexibility for the article to cover a broad range of circumstances. It is not mandatory unless so specified by others in the application of these articles.
Fantastic! I got it very clearly.
Have another code could check about "Shall", "May", "Should" data require?

"shall" indicates a requirement;
"should" indicates a recommendation;
"may" indicates a permission;
"can" indicates a possibility or capability.

The point on it not being mandated by law is correct, however.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
