Terms and definitions For the purposes of this document, the following term and definition applies.
sling tape,accessory cord or rope joined together by stitching or other means of fastening. The shape and lengthare not specified.
When shuttleless loom webbing is used, the weft shall be locked by an additional locking thread or by any othersystem, which guarantees that the edges cannot be unravelled when one of the yarns breaks.
Where stitching is used to provide safety and strength (e.g. in joints) the visible area of stitching shall contrastwith the tape in colour or surface appearance.Carry out a visual examination to check that the requirements specified in 4.2 are met.
One sample of the shortest length of the sling type shall be tested.The test shall always be carried out on an unused test sample.
Condition the test samples as described in EN ISO 139.
Carry out the test at a relative humidity which may be outside the standard atmosphere given in EN ISO 139, butat a temperature of (23 ±5)°C, in which case the test shall begin within 5 min of removal from the conditioningatmosphere.
Determination of tensile strength Attach the test sample between two bars offering a contact radius of (5±0,05) mm to the sling and with a meanroughness value, R , not exceeding 0,8 um and a peak to valley height, Rmav, not exceeding 6,3 um.
Slings shall be marked with at least the following items which shall be given at least in the official language(s) ofthe state of destination within the European Community:
a) name of the manufacturer or its representative in the European Community;
b)tensile strength which the manufacturer ensures at the time of manufacturing;
c)number of this European Standard, i.e.EN 566;
d) year of manufacture.BS EN 566 pdf download.
