American National Standard

2、An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufac-turer, the consumer, and the general public. The existence of an American National Standard does not in any respec

3、t preclude anyone, whether they have approved the standard or not, from manu-facturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic review and users are cautioned to obtain the latest editions.

4、 The American National Standards Institute does not develop standards and will in no circumstanc-es give an interpretation of any American National Standard. Moreover, no persons shall have the right or authority to issue an interpretation of an American National Standard in the name of the American

5、 National Standards Institute. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken to reaf-firm, revise, or withdraw this standard no later than five years from the date of p

8、s Foreword is not a part of ANSI/ISEA Z87.1-2015) This document is the latest edition of a standard for eye and face protection that dates back to 1922. Originally part of a government standard that also included respiratory and head protection, the standard first appeared under the Z87.1 designatio

9、n in 1968, and has been revised five times since then in response to advances in technology, as well as the changing workplace environment. ANSI/ISEA Z87.1-2015 represents another milestone in this standards evolution, building on the many years of work that have gone into prior revisions. The docum

10、ent continues to focus on product performance and harmonization with global standards in an effort to allow new and inno-vative designs responsive to workplace hazards, end-user needs and regulatory obligations. Since the 2010 revision was a dramatic shift away from product configuration requirement

11、s and toward a hazard-based structure, much of the revised language in ANSI/ISEA Z87.1-2015 reflects the effort to fine-tune this approach. Streamlined language for resolution testing provides clarity to test methods to ensure they can be accurately executed, and updated test patterns to complement

12、the language. These patterns can be downloaded from ISEAs website at www.safetyequipment.org. Other key updates address the emergence of new technologies that are challenging outdated design restrictions, or which past editions did not contemplate. This includes the acknowledgement of protectors kno

13、wn as “magnifiers” and “readers” that have lenses, or portions of lenses, that incor-porate magnification properties. The 2015 revision also eliminates minimum thickness require-ments for non-prescription protectors that pass the requirements for impact rated protectors, and eliminates the need to c

14、onduct drop-ball testing for a protector that is first tested to and meets the im-pact-rated requirements. Requirements for angular dependence of luminous transmittance for weld-ing filters have been added to address visual effect that welders can find both alarming and dis-tracting. Such requiremen

15、ts are consistent with criteria in similar global standards. As the standard continues to focus on specific hazard protection, additional emphasis has been placed on enabling users to select protectors appropriate for the working environment, and present-ing end-users with information to assist in t

16、he selection process. Examples of acceptable and un-acceptable markings for protectors that meet the requirements of the standard are included. In ad-dition, information related to conducting an assessment for potential eye and face hazards and pro-tector use and selection considerations has been ex

17、panded. Suggestions for improvement of this standard are welcome. They should be sent to the International Safety Equipment Association, 1901 N.
