What does the term 'should' indicate in API standards?

The term 'should' in API standards signifies a recommendation or guidance that is advised but not formally mandated. It implies that adherence to the suggestions provided is encouraged to achieve best practices or optimal outcomes, but it does not establish a mandatory requirement. This allows for some flexibility, enabling manufacturers or practitioners to make informed decisions based on their specific circumstances while still aiming for high-quality and safety standards. It distinguishes itself from other terms in the standards that indicate absolute requirements, highlighting a preference rather than an obligation. Understanding the nuance of 'should' is essential for professionals in the field, as it delineates best practices without enforcing strict compliance.
