14、 is the first edition of ANSI/ASSE Z359.18. It establishes requirements for performance, design, mark-ing, qualification, instruction, training, inspection, use, maintenance and removal from service of anchorage connectors that were formerly part of the ANSI/ASSE Z359.1-2007 standard. This standard

15、represents a significant step forward in the realm of anchorage connectors. The ANSI Z359.18 subcommittee focused on two aspects of anchorage connectors when developing this standard anchorage connectors of questionable strength and clearer instructions to users. As we took these two aspects, we org

16、anized them into three specific facets in which the industry could measure our success. 1. Testing requirements2. Integrity of substrate attachment3. Instructions for useThe previous standard for anchorage connectors, ANSI/ASSE Z359.1-2007 is considered overly simplistic for these facets. In additio

17、n to weakness in these three facets, there was no clear direction with regard to the anchorage in the previous standard. A critical aspect for the performance of anchorage connectors is the interaction between the anchorage connector and the anchorage where it is used. This standard now includes dyn

18、amic testing of the anchorage connector installed on substrates that represent the intended installation and use. There is also a requirement related to the ANSI/ASSE Z359.7 standard and the need for a ISO 17025 accredited laboratory. For background, these were not required for anchorage connectors

19、in ANSI/ASSE Z359.1-2007.For the first facet, this standard tests in a manner that more closely represents actual use of the anchorage connectors. In addition to static and dynamic strength and performance testing, this standard also includes residual strength testing to verify strength after a fall

20、 has occurred, and in some cases, serviceability testing to verify that deformable anchorage connectors will not deform under the working loads permitted by the manufacturers. Corrosion testing requirements are included and increased for anchorage connectors that are expected to serve for many years

21、 in outdoor settings, such as a Type T anchorage connector for tiebacks.For the second facet, this standard requires testing of anchorage connectors in a substrate that represents real world applications. This is an area of great concern to the technical committee because even the stron-gest anchora

22、ge connector can fail if it is improperly installed, or installed on structures that have inadequate strength. For this reason, purchasers of equipment certified to this standard should also refer to the ANSI/ASSE Z359.2 and ANSI/ASSE Z359.6 standards for certification of INSTALLED anchorage connect

23、ors. The Z359 accredited standards committee expects future revisions of this standard will improve testing of installed anchorage connectors. We anticipate developing more specific fixturing requirements in the future that will further increase assurance to users that Z359 anchorage connectors are

24、fit for service.The third facet builds on the second requiring clear instructions to reduce the misuse of anchorage connec-tors. We anticipate future markings and the continuing universal use of smart devices will allow authorized persons, competent persons and other involved parties to have access

25、to instructions and other pertinent information from manufacturers on the proper and improper installations, uses and inspection of their an-chorage connectors.As with any fall protection standard, the ultimate goal is to improve the level of safety experienced by the user. This standard accomplishe

26、s this by requiring testing to more accurately represent the intended use of anchorage connectors, and providing clearer user instructions. This is an ASSE-produced standard.

28、ditions to the current suite of anchorage connectors it has been written to address. We believe it provides a frame-work that will allow changes to validate and qualify anchorage connectors in an ever evolving market. One of the committees primary objectives to facilitate this goal was to provide ma

29、nufacturers a structure that will allow inclusion of new products in a timely fashion and quickly addresses concerns from potential prod-uct misuse, the purpose of which is to product that safely meets user needs.The standards in the Fall Protection Code are constantly evolving, and are revised on a

30、 regular schedule in conformity to ANSI requirements. The Z359 Committee solicits public input that may suggest the need for revisions to this standard. Such in-put should be sent to the Secretariat, ASC Z359, American Society of Safety Engineers, 520 N. Northwest Highway, Park Ridge, Illinois 60068
