6、rrent rules of presentation. There are no European documents covering the same subject as this standard. The responsible German body involved in the preparation of this standard was Working Committee NA 045-02-05 AA Frdergurte of the Normenausschuss Kautschuktechnik (FAKAU) (Rubber Technology Standa
7、rds Committee). DIN 22102 consists of the following parts under the general title Conveyor belts with textile plies for bulk goods: Part 1: Dimensions, specifications, marking Part 2: Testing Part 3: Permanent joints Attention is drawn to the possibility that some of the elements of this document ma
8、y be the subject of patent rights. DIN and/or DKE shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN 22102-3:1991-04 as follows: a) it has been brought in line with the current rules of presentation; b) the standard has been editori
9、ally revised; c) figures have been revised. Previous editions DIN 22102-3: 1991-04 3DIN 22102-3:2014-01 1 Scope This standard describes splices for permanently splicing conveyor belts with textile plies as in DIN 22102-1 by means of either hot or cold splicing. See DIN 22102-1 for the symbols used.

33、: a) date of splice manufacture (month and year); b) manufacturers symbol; c) splice number; d) fitters symbol. The letters and numbers in the marking shall be at least 20 mm high with a line width of at least 3 mm. Groups of numbers and/or letters shall be separated by a space. EXAMPLE 4/11 NN 15 21 14
