BS 8407:2002 pdf free.Specification for mechanical and spliced joints in conveyor belting for use underground.
BS 8407 1 Scope This British Standard specifes requirements for joints made in conveyor belting for use underground.It specifies performance requirements for the following properties: 一joints made with mechanical fasteners (static strength); 一joints made with mechanical fasteners (dynamic strength);一joints made by chemical splicing/vulcanization (static strength); joints made by chemical splicing/vulcanization (dynamic strength).The methods of test to be used to validate the requirements are specified in the annexes. This standard is not applicable or valid for light conveyor belts as specified in BS EN 873.NOTE Although this standard is intended to specify the requirements for conveyor belting, the test methods specified in 4.1.1and 4.2.1 can aleo be used to 88e88 the performance of mechanical fasteners when ueed with specifie types of conveyor belting. For this reason, an alternative test configuration is specified in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. BS EN ISO 1120, Conveyor belts一Determination of strength of mechanical fastenings一Static test method. BS 3289, Specification for textile carcass conveyor belting for use in underground mines (including fire performance). BS 1610, Methods for the load verification of testing machines. 3 Terms and definitions
For the purpose of this standard, the following terms and defnitions apply: fastener pitch the nominal distance between a point on a fastener unit and the corresponding point on the next fastener unit (see Figure A.1 and Figure A.2) 3.2 fastened width the number of fastener units inserted in one end of a test piece multiplied by the pitch (see Figure A.1and Figure A.2) 3.3 nominal tensile strength
the specified minimum value of the tensile strength of the conveyor belt, expressed in N/mm joints the joining of individual lengths of conveyor belting to produce a longer length NOTE This should not be confused with transverse (or longitudinal) fabric joints made during the production process for multi-ply belting.BS 8407 pdf download.
