EN 1263-1:2002 (E)4ForewordThis document (EN 1263-1:2002) has been prepared by Technical Committee CEN /TC 53, "Temporary worksequipment", the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by October 2002, and conflicting national standards shall be withdrawn at the latestby October 2002.This document supersedes EN 1263-1:1997.This European Standard is one of a series of standards as listed below:EN 1263-1, Safety nets — Part 1: Safety requirements, test methods.EN 1263-2, Safety nets — Part 2: Safety requirements for the erection of safety nets.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.The annexes A and B are informative.SIST EN 1263-1:2002
EN 1263-1:2002 (E)5IntroductionSafety nets for use in construction and other assembly work, e.g. as devices to catch falling persons during theconstruction of halls and bridges, in open line construction as side protection, as anti-fall devices or devices tocatch falling persons on working scaffolds, as side protection for safety scaffolds at roofs and in tunnelling can bechosen as a technically suitable and economic solution to catch persons falling from a height. They serve to protectfrom deeper falls even when large areas in plan occur.In contrast to being secured by a lanyard and harness the mobility of persons working above the area protected bysafety nets is not impaired during all work activity. Moreover, the use of safety nets has the advantage to catchpersons falling from a height more softly than lanyards caused by large plastic deformations of the net.Attention should be paid to the fact that the ageing sensitivity of safety nets due to exposure to UV requires thatthey are exposed to open air condition a limited time only and then be withdrawn from service. For the evaluation ofthe ageing behaviour tests have been carried out over a period between 6 months and 24 months which apply tothe most commonly used materials polyamide and polypropylene. The specifications of the limit values of breakingenergy are based on these tests and on drop tests with articulated dummies and test spheres. After having beensubjected to respective loading by persons falling from height the safety nets should be replaced, if appropriate.1 ScopeThis European Standard applies to safety nets and their accessories for use in construction and assembly work toprotect from deeper fall. It specifies safety requirements and test methods and is based on the performancecharacteristics of polypropene and polyamide fibres. Materials used in nets should have no significant reduction inmechanical properties between – 10 °C and + 40 °C.This standard is not applicable to the installation of safety nets.

Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter.
