What is a "Technical Inquiry"?

A technical inquiry (also known as a request for an interpretation) is a question submitted to API on the meaning of a requirement in a standard.

How to Submit a Request for an Interpretation

API will only consider written e-mail requests for interpretations. These requests must include the following:

• Standard number and name.
• Standard edition (including addenda) and year.
• Specific section number in question.
• Any background information that may be helpful in understanding the question.

The inquiry shall involve a single subject or closely related subjects. The inquiry shall be stated in a condensed and precise question format. The inquiry shall be composed so that "yes" or "no" (perhaps with provisos) would be a suitable reply. This inquiry statement should be technically and editorially correct. The inquirer shall state what they believe the standard requires. If in the inquirer's opinion a revision to the standard is needed, they shall provide recommended wording for consideration by the responsible committee. Responses to inquiries can take up to 12 months.

Please review the contact list and submit your inquiry to the appropriate API Staff Contact.
