ANSI Z97.1-2004 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. It is recommended
that this standard be referenced but not incorporated in any
statute.
The impact tests
described in this standard are based on realistic
information and criteria but it must be acknowledged that in
a small number of cases, involving rare coincidence,
somewhat larger impact forces could be developed.
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. The accredited standards
committee (ASC) has carefully considered the inclusion of a
widely used center punch fragmentation test in the standard
as a secondary method for testing tempered glass. The ASC
decided that while this test is a common quality control
method used in the tempering industry, the actual evaluation
and reporting of the test results needs further study. The
tempering division of the Glass Association of North America
(GANA) has agreed to pursue the development of this test and
will propose a center punch fragmentation test for
consideration at the next review of this standard.
This standard is a
successor standard to the 1994 edition. The 1994 standard
was a reaffirmation of the 1984 standard with various
editorial changes and the 1984 standard succeeded those of
the 1975, 1972 and 1966 editions.
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, Z97.1 Main

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 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.
ANSI Z97.1-2004 Scope
1.1 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 to reduce
or minimize the likelihood of cutting and piercing injuries
when the glazing materials are broken by human contact) as
used for all building and architectural purposes.
