22、 Switzerland and the United Kingdom. Endorsement notice The text of ISO 2307:2010 has been approved by CEN as a EN ISO 2307:2010 without any modification. DIN EN ISO 2307:2011-01 EN ISO 2307:2010 (E) 3 “1 Scope This International Standard specifies, for ropes of different kinds, a method of determin
23、ing each of the following characteristics: linear density; lay length; braid pitch; elongation; breaking force. The linear density, lay length and braided pitch are measured with the rope under a specified tension called the reference tension, as specified in Annex A. The elongation corresponds to t
24、he measured increase in length of the rope when the tension to which it is subjected is increased from an initial value (reference tension) to a value equal to 50 % of the minimum specified breaking strength of the rope. The breaking force is the maximum force registered (or reached) during a breaki
25、ng test on the test piece, carried out on a tensile testing machine with constant rate of traverse of the moving element. The breaking force values given in the tables of rope specifications are only valid when this type of testing machine is used. When it is not possible to test the whole section o
26、f rope, the method described in Annex B can be used, subject to agreement between the parties involved. This International Standard also provides a method for measuring water repellency, lubrication and finish content, and heat setting treatment, when requested by the customer. 2 Normative reference

Different types of tensile tes
33、ting machines may be used: pulley-type grip (“cors de chasse” testing machine); testing machine with bollards for eye splices; wedge-grip testing machine. In the case of a “cors de chasse” tensile testing machine, the diameter of the pulleys or catches holding down the test pieces shall be equal to
34、at least 10 times that of the rope being tested. In the case of a testing machine with bollards, the diameter of the bollards passing through the eye-spliced test pieces shall be at least twice the diameter of the rope being tested.

For the linear d
42、ensity, perform the procedures specified in 9.8. 9.2 Initial measurements Lay the test piece out straight on a flat surface by pressing with a slight force of the hand (not exceeding 20 % of the reference tension) (see Annex A).

43、to its mid-point, and at a distance apart of l0that is greater than 400 mm.

44、nife at right angles to its longitudinal axis at the seizings, so that a suitably seized sample is obtained. 12.2.4 Sealing To prevent absorption by capillary action, seal the ends off so that the whipping is just covered. A suitable sealing material is pitch with a small amount of tar added to prev
45、ent cracking. Any other suitable sealing material may be used. 12.3 Procedure 12.3.1 First weighing Carefully weigh each specimen after whipping and sealing, and then place it in tap water at a temperature of (20 2) C, taking care that the specimen is fully submerged, if necessary by weighting down,
46、 to a depth of 150 mm. Do not add water after the specimens have been submerged. In order to avoid the variations in mass due to atmospheric conditions, carry out the weighing immediately before immersion. Do not carry out the test until at least 24 h after the completion of manufacture of the rope.
47、 12.3.2 Second weighing After a total immersion of 1 h, take the specimens out of the water and, before weighing, dry them in the following manner. Shake each specimen six times to remove the superfluous water and then roll the sample on blotting paper until no wetting of the paper is observed. Fina
48、lly, draw the specimens three times through an absorbent cloth, such as towelling. Then weigh the specimens and resubmerge in the water. 12.3.3 Third weighing After a further 5h immersion period (making a total of 6 h in all), dry the specimens as described in 12.3.4 and weigh them. 12.3.4 Drying th
49、e specimens Thoroughly dry each specimen by gentle heating, if necessary. Take care that the sealing is not affected by the temperature, and that the temperature does not exceed 50 C. Dry the specimens to a mass slightly less than that obtained at the first weighing, so that, after exposure for at least 4 h to normal room atmospheric conditions, the specimens shall return as nearly as possible to their original mass. 12.3.5 Fourth, fifth and sixth weighing Repeat the procedure described in 12.3.1 to 12.3.4 using the same specimens. 12
