Revision to ANSI E1.1-1999 Wire Rope Ladder Standard is Available for Public Review
A revised version of the existing ANSI E1.1-1999, Entertainment Technology - Construction and Use of Wire Rope Ladders, is available for public review through 13 December 2005. The document is available on the ESTA website at http://www.esta.org/tsp/documents/public_review_docs.php.
The revised version of E1.1 is being offered for public review because substantive changes were made to the SI measurements given in the last public review version. The SI and American customary dimensions were substantially different, so these have been modified to make them functionally the same.
Reviewers are asked to see if the document now gives adequate and accurate guidance on the construction and use of wire rope ladders, and are also asked to identify any protected intellectual property they might see in the draft document. ESTA does not intend to publish any standard that contains protected intellectual property unless that property is required for technical reasons and can be licensed by anyone on a non-discriminatory basis for a reasonable fee. ESTA does not warrant that its standards contain no protected intellectual property.
The revision of ANSI E1.1-1999, Entertainment Technology - Construction and Use of Wire Rope Ladders, is being done by the Rigging Working Group. Membership in the working group is open to all who are affected by the work of the group, but the working group is actively seeking members in the interest categories of dealer/rental companies and users, so that the working group may better reflect the diversity of interests in the industry. More information about working group membership and a membership application are available at http://www.esta.org/tsp/about/workgroups.html.
