3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. tensile strength
greatest measured force during the tensile test divided by the width of the test piece NOTE It is expressed in newton per millimetre (N/mm).
3.2
reference force reference load
one tenth of the nominal tensile strength in the longitudinal direction multiplied by the width of the test piece in millimetres
NOTE It is expressed in Newton.
EXAMPLE
Nominal tensile strength = 1 600 N/mm:
reference force = 160N/mm;
reference force for 25 mm test piece 25mm x 160 NImm 4 000 N.
3.3
slab belting
conveyor belting made in wide widths and long lengths for subsequent slitting and cutting into narrower widths and shorter lengths to suit individual conveyor installations
3.4
solid woven belting
conveyor belting consisting of a carcass of more than one ply, the plies being interlocked in the weave or bound together by binding threads in the course of weaving
3.5
mono-ply belting
conveyor belting with a carcass consisting of one ply of woven textile fabric
3.6
duo-ply belting
conveyor belting with a carcass consisting of two plies of woven textile fabric, bonded together by an intermediate layer of elastomer of sufficient thickness to allow the incorporation of a tension element in the joint
3.7
multi-ply belting
conveyor belting with a carcass of two or more plies of woven textile fabric, the adjacent plies being bonded together by an intermediate layer of elastomer
3.8
primary yarn
load carrying yarn that contributes more than 50 % of the tensile strength
3.9
secondary yarn
load carrying yarn that contributes less than 50 % of the tensile strength.ISO 14890-2013 pdf free download.
