DIN EN 1263-1:2015-03 EN 1263-1:2014 (E) 5 Introduction Safety nets for use in co
28、nstruction and other assembly work, e.g. as devices to catch falling persons during the construction of halls and bridges, in open line construction as side protection, as anti-fall devices or devices to catch falling persons on working scaffolds, as side protection for safety scaffolds at roofs and
29、 in tunnelling can be chosen as a technically suitable and economic solution to catch persons falling from a height. They serve to protect from deeper falls even when large areas in plan occur. In contrast to being secured by personal protective equipment against falls from heights the mobility of p
30、ersons working above the area protected by safety nets is not impaired during all work activity. Moreover, the use of safety nets has the advantage to catch persons falling from a height more softly than lanyards caused by large plastic deformations of the net. Attention should be paid to the fact t
31、hat the ageing sensitivity of safety nets due to exposure to UV requires that they are exposed to open air condition a limited time only and then be withdrawn from service. For the evaluation of the ageing behaviour tests have been carried out over a period between 6 months and 24 months which apply
32、 to the most commonly used materials polyamide and polypropylene. The specifications of the limit values of breaking energy are based on these tests and on drop tests with articulated dummies and test spheres. After having been subjected to respective loading by persons falling from height the safet
33、y nets should be replaced, if appropriate. DIN EN 1263-1:2015-03 EN 1263-1:2014(E)6 1 Scope This European Standard applies to safety nets and their accessories for use in construction and assembly work to protect from deeper fall. It specifies safety requirements and test methods and is based on the
34、 performance characteristics of polypropene and polyamide fibres. Materials used in nets should have no significant reduction in mechanical properties between 10 C and +40 C. This European Standard is not applicable to the installation of safety nets. For a European Standard covering the installatio
35、n of safety nets, see EN 1263-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
