Definitions:• Strap load capacity (LC): the maximum load for use under straight line traction a fabric strap hasbeen designed to support under o<strong>per</strong>ating conditions.• Manual o<strong>per</strong>ating load (Hf): load applied to the handle as producing the traction load in thefabric strap.• Standardized manual load (SHF): manual o<strong>per</strong>ating load of 500 N (50 daN on the <strong>la</strong>bel).• Standardized traction load (STF): residual load after releasing the ratchet handle.• Tensioner: a mechanical device which triggers and maintains a traction load in a load securingdevice (e.g. ratchets, turnbuckles etc.).• Inspection: visual testing of the state of the tie down, to check for clear damage or wear whichmay affect its use.• Trained <strong>per</strong>son: a designated, suitably trained <strong>per</strong>son who has pro<strong>per</strong> know-how and practicalex<strong>per</strong>tise and has been given the instructions needed to <strong>per</strong>form any required tests andexaminations.2) TESTING SPECIFICATIONSThe accessory is subjected to several stringent tests for serviceability, <strong>per</strong>formance and compliancewith <strong>specifica</strong>tions.The number of samples and the re<strong>la</strong>ted sampling p<strong>la</strong>ns are chosen according to the characteristic totest under UNI ISO 2859/1, and the results are filed in the quality department of the factory inSulmona.2.A Visual testTesting for such im<strong>per</strong>fections as cuts, breaks and defects on the strap stitches,cracks, splits or deformations on the terminals and ratchets.2.B Ratchet pretensioning testsThe accessory is subjected to a pretensioning test by applying a force of 50 daN to thetensioner lever and measuring the released tension on the strap, under UNI EN12195-2.At the end of the test the system should not have suffered any damage and should be<strong>per</strong>fectly serviceable.2.C Tensile stress testThe test comprises two phases: the former consists in loading the strap to 1.25 LC asmaintained for one minute; afterwards none of the supporting parts of the entire strapshould show any signs of deformation or any other defects that may affect itso<strong>per</strong>ation. Following an accurate inspection, 2 LC load is applied, which should notcause any breaks in the strap.Division of BETA UTENSILI SPA, Via Volta, 18 - 20845 SOVICO (MB) ITALY Tel. +39.(0)39.20771-Fax + 39.(0)39.2010742
