What does "should" typically mean in the context of codes or standards?

In the context of codes or standards, the term "should" is commonly understood to indicate a recommendation rather than a mandatory requirement. This means that while following the guideline is advised for best practices and improved safety or performance, it is not legally enforceable. The use of "should" allows for professional judgment and discretion in its application, permitting variations based on situational needs or specific circumstances.

Other terms in code language indicate different levels of obligation, such as "must" which would denote an essential rule that is mandatory and must be followed without exception. Similarly, "may" suggests a permissible action but does not imply a recommendation or good practice. Understanding these distinctions helps professionals navigate regulations effectively and apply the best practices as suggested, without implying a legal requirement.
