Temporary works equipment - Safety nets - Part 1: Safety requirements, test methods
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 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 installation of safety nets, see EN 1263 2.
Temporäre Konstruktionen für Bauwerke - Schutznetze (Sicherheitsnetze) - Teil 1: Sicherheitstechnische Anforderungen, Prüfverfahren
Diese Europäische Norm gilt für Schutznetze und Schutznetzzubehör, die bei Bau- und Montagearbeiten Verwendung zum Schutz gegen tieferen Absturz finden. Sie legt sicherheitstechnische Anforderungen und Prüfverfahren fest und basiert auf den Verhaltenseigenschaften von Polypropylen- und Polyamidfasern. Die für Schutznetze verwendeten Materialien sollten keine wesentlichen Verminderungen der mechanischen Eigenschaften zwischen 10 °C und 40 °C aufweisen.
Diese Europäische Norm gilt nicht die Errichtung von Schutznetzen fest. Für die Errichtung von Schutznetzen siehe EN 1263-2.

Začasne konstrukcije za gradnjo - Varovalne mreže - 1. del: Varnostne zahteve, preskusne metode
Ta evropski standard velja za varovalne mreže in njihove priključke, ki se uporabljajo pri gradnji in montaži kot zaščita pred padcem z večje višine. Določa varnostne zahteve in preskusne metode ter temelji na kakovostnih lastnostih polipropenskih in poliamidnih vlaken. Mehanske lastnosti materialov, uporabljenih v mrežah, naj se ne bi bistveno zmanjšale pri temperaturah od –10 °C in +40 °C.
Ta evropski standard se ne uporablja za nameščanje varovalnih mrež. Za evropski standard, ki zajema nameščanje varovalnih mrež, glej EN 1263-2.

5.2 Rope The designation of a rope shall include its denomination in accordance with 4.3, Table 2, and a reference to this European Standard. 6 Requirements 6.1 Construction 6.1.1 Mesh rope The mesh rope construction shall have a minimum of three independent threads and shall be constructed in such a way that it cannot unravel. Mesh rope shall be tested in accordance to 7.3. During the test, the mesh rope shall be able to hold the test mass without sustaining the damage. NOTE Knotted net construction is unlikely to exhibit this condition. 6.1.2 Net Nets shall be made with a square (Q) or diamond (D) mesh, see Figure 6 a) and Figure 6 b). The mesh size lM shall not exceed 60 mm for net classes A 1 and B 1 and 100 mm for net classes A 2 and B 2, see Figure 6. The mesh size shall be checked in accordance with 7.2. The loose ends at the edge of the net shall be secured to prevent the net unravelling, see Figure 6. SIST EN 1263-1:2015

The joint between the ends of a border rope shall be secured against unintentionally becoming undone. This can be achieved, e.g. by splicing. Border rope shall be tested in accordance with 7.3. 6.1.4 Other ropes The ends of all ropes used in safety nets shall be secured against unravelling, e.g. by melting or tying or sewing with rigging yarn. The knots or connections between the ends of ropes within the selvage of a net shall be secured against unintended opening. This can be managed, e.g. by sewed overlocking of a minimum of 200 mm. The internal length of a loop shall be at least 150 mm, see Figure 5. 6.1.5 Test mesh for yearly inspection Safety nets shall be provided with at least one test mesh. The test mesh shall be loosely threaded through the meshes of the net and be attached in the border area. The test mesh shall come from the same production run as that used for the related net. In order to ensure that the test mesh origin can be properly identified (with the related netting), seals with the same identity number shall be fixed to the test mesh and to the related net.

The Rope F shall have a minimum tensile breaking force of 20,0 kN when tested in accordance with 7.5. The Ropes F, G, H, R, J, L, M and Z shall be twisted or braided. NOTE The values of the minimum tensile breaking force include a safety factor of 2,0. 6.2.3 Coupling rope Rope N and Rope O shall have a minimum tensile breaking force of 7,5 kN when tested according to 7.5. The Ropes N and O shall be twisted or braided. NOTE The value of the minimum tensile breaking force includes a safety factor of 2,0. 6.3 Energy absorption capacity of the test mesh When testing for yearly inspection it shall be shown that the test mesh has a sufficient resistance with respect to its deterioration due to ageing over a one year period. The sufficient capacity by taking account of ageing shall be verified according to 7.7. 6.4 Static strength of a net sample 6.4.1 Breaking energy The breaking energy EO in kilojoules of a net in the as new state shall be at least: E0 ≥ EN × 1 × 2 SIST EN 1263-1:2015

The maximum instantaneous deflection of the net under dynamic action shall not exceed 75 % of the length of the shortest side of the net. The test mass shall be held by the net in each test. Permanent deformation and breaking of several mesh ropes is permitted. 6.6 Dynamic strength of safety net System T (net attached on brackets for horizontal use) Safety nets System T shall be tested according to 7.10. The maximum instantaneous deflection of the net under dynamic action shall not exceed the length of the shortest side of the net. The test mass shall be held by the net in each test.

The test mass shall be held by the net in each test. Permanent deformation is permitted. The mesh ropes at the edge of the net shall not brake. 6.8 Dynamic strength of safety net System V (net with border rope attached to a gallow type support) Safety nets System V shall be tested according to 7.12. The maximum instantaneous deflection of the net under dynamic action shall not exceed 50 % of the length of the shortest side of the net. The test mass shall be held by the net in each test.
