ANSI Z97.1-2015 (R2020) Forward

This Standard was developed under procedures accredited as meeting the criteria for American National Standards. The consensus committee that approved the Standard was balanced to ensure that individuals from competent and concerned interests have had an opportunity to participate. It was developed within the approved scope as stated in section 1.1 of the standard.

This Standard is available for public review on a continuing basis. This provides an opportunity for additional public input from industry, academia, regulatory agencies, and the public-at-large. The use of an addenda system will allow revisions made in response to public review or committee actions to be published as required.

This Standard, which is the result of extended and careful consideration of available knowledge and experience on the subject, is intended to provide minimum requirements that are recommended for use, adoption, enforcement by federal, state and local authorities and by model codes. This standard is to be referenced but not incorporated in any statute or any other standard without the prior written permission of the publisher.

This Standard does not recommend where safety glazing should be used or, when it is used, what type of glazing material should be used. For this information one should consult other codes, standards and manufacturer's information.

Neither the standards committee nor the secretariat feel that this standard is perfect or in its ultimate form. It is recognized that, although safety-glazing materials are widely used and accepted, new developments are to be expected and revisions of the standards are necessary as the art progresses and further experience is gained.

This standard is a successor standard to the 2009e2 edition. The 2009e2 standard succeeded those of the 2009e, 2009, 2004, 1984 (reaffirmed in 1994), 1975, 1972 and 1966 editions.

The 2015 edition of ANSI Z97.1 has removed reference to Class C, 12 inch drop height and fire-rated wired glass. No test methods, references or exceptions appear in this document for Class C, 12 inch drop height and fire-rated wired glass. Compliance of all safety glazing products must be rated to either Class A or Class B in accordance with the procedures of this edition.

In order for material to be considered for reference or to continue to be referenced in the ANSI Z97.1 standard, it shall meet the following criteria:

  1. The referenced material, including title and date, and the manner in which it is to be utilized shall be specifically identified in the text of ANSI Z97.1.
  2. The standard or portions of a standard intended to be enforced shall be written in mandatory language.
  3. The scope or application of the reference material shall be clearly described.
  4. The referenced material shall not have the effect of requiring proprietary materials.
  5. The standard shall not prescribe a proprietary agency for quality control or testing. For communication with the Committee please refer to the following page

General. ANSI Codes and Standards are developed and maintained with the intent to represent the consensus of concerned interests. As such, users of this Standard may interact with the Committee by requesting interpretations, proposing revisions, and attending Committee meetings. Correspondence should be addressed to:

Secretary, Z97 Main Committee
c/o Julia Schimmelpenningh
Eastman Chemical Company
1945 Old Gallows Rd., Ste 650
Vienna, VA 22181

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.

Interpretations. On written request, the ASC Z97 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.

The committee reserves the right to reconsider any interpretation when or if additional information, which might affect that original interpretation, becomes available to the Committee. Persons aggrieved by an interpretation may appeal to the Committee for reinterpretation. The ASC Z97 does not "approve," "certify," "rate," or "endorse," any item, construction, proprietary device, or activity beyond what is addressed in the Standard.

ANSI Z97.1-2015 (R2020) Scope

This standard establishes the specifications and methods of test for the safety properties of safety glazing materials (glazing materials designed to promote safety and reduce the likelihood of cutting and piercing injuries when the glazing materials are broken by human contact) as used for all building and architectural purposes.
