ANSI Z97.1-2015 (R2020) Interpretation/Modification Requests

Proposing Revisions
Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Standard. Approved revisions will be published periodically.

The Committee welcomes proposals for revisions to this Standard. Proposals should be as specific as possible: citing the paragraph number(s), the proposed wording and a detailed description of the reasons for the proposal. Pertinent documentation should be included.

On written request, the Z97.1 Committee will render an interpretation of any requirement of the Standard. The request for interpretation should be clear and unambiguous.

The following format is recommended:

Subject:  Cite the applicable paragraph number(s) and provide a concise description.
Edition:  Cite the edition of the Standard for which the interpretation is being requested.
Question:  Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use not a request for an approval of a proprietary design or situation.

Requests that are not in the above format may be rewritten by the Committee or its Secretary prior to being answered, which may inadvertently change the intent of the original request. The Committee reserves the right to deem certain requests for interpretations as not within its scope or expertise and refuse to address them.
