The work
9、of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-government
10、al, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The mai
11、n task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Att
12、ention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22774 was prepared by the European Committee for Standardization (CEN) in collaboration with Technic
13、al Committee ISO/TC 216, Footwear, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

23、nce of a shoe lace to repeated rubbing: Method 1: lace to lace abrasion; Method 2: lace to standard eyelet abrasion; Method 3: lace to eyelet (from footwear) abrasion. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated referenc
24、es, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12222, Footwear Standard atmospheres for conditioning and testing of footwear and components for footwear 3 Terms and definitions For the purposes of this
25、document, the following terms and definitions apply. 3.1 abrasion resistance of shoe laces ability of the shoe lace to resist to repeated rubbing against either a similar shoe lace or a lace carrier 3.2 number of cycles to failure arithmetic mean of the number of cycles to failure for the test speci
26、mens submitted to test 3.3 type of failure expressed as failure of the shorter lace or failure of the longer lace, together with a description of the respective amount of wear in the covering and core of each lace 4 Principle A shoe lace is threaded through a loop formed by: - a piece of similar lac
27、e held open by a spacer (Method 1); - a lace carrier (Methods 2 and 3). The shoe lace is bent through a fixed acute angle at the point of contact with the loop. It is then held under a standard tension while it is repeatedly drawn back and forth through the loop until it fails. Copyright Internation

29、erials 5.1 General 5.1.1 A test machine with one or more test stations, see Figure 1, each having: NOTE Test machines with less than six stations are also acceptable to conduct this test. In which case the test should be repeated until six test specimens have been tested (see 8.1.6). 5.1.2 A moveabl
30、e clamp which has a means of firmly holding: - both ends of a piece of shoe lace (Method 1); - one end of the metal strip (see 5.1.8) (Methods 2 and 3). 5.1.3 A stationary clamp which is mounted in the same horizontal plane as the moveable clamp (5.1.1) and is capable of holding one end of a shoe la
31、ce. The stationary clamp should be 280 mm 50 mm from the moveable clamp (5.1.2) when the clamps are at their minimum separation, this distance will subsequently be referred to as D. 5.1.4 A tensioning device with a method of holding the end of a piece of shoe lace at a point 35 mm 5 mm to one side o
32、f, and in the same horizontal plane as, the stationary clamp (5.1.3) and applying a tensioning force of 2,45 N 0,03 N, see Figure 1. This can be achieved by passing the shoe lace over a pulley and suspending a mass of 250 g 3 g from the lower end of the vertical portion of the lace. 5.1.5 A means of
33、 moving the moveable clamp (5.1.2) with a simple harmonic reciprocating motion through a distance of 35 mm 2 mm and back to the original starting position at a rate of 60 cycles per minute 6 cycles per minute. 5.1.6 A means of counting the number of abrasion cycles up to failure of the lace or lace
34、carrier. 5.1.7 For Method 1: - a rigid spacer device of width 25 mm 5 mm. This is used to hold the two legs of the loop of lace which is clamped in the moveable clamp (5.1.2) apart (see Figure 1), so that when it is under tension the end of the loop forms an isosceles triangle with the spacer as its
35、 base and the two parts of the lace are at an angle of 52,5 5,0; - a template with an angle of 52,5 marked on it, for setting the position of the spacer device. 5.1.8 For Method 2, a metal strip of width approximately 25 mm, thickness approximately 1 mm and length approximately D 60 mm. One end of t
36、he strip should fit into the moveable clamp (5.1.2) and the other end should be capable of holding the test lace carrier.

If sufficient made shoe laces are available, cut each test specimen from a separate lace. 6.1.2 Cut six pieces of shoe
42、lace each of length 500 mm 10 mm. If sufficient made shoe laces are available, cut each test specimen from a separate lace. For some equipment it is possible to use pieces of lace as short as 100 mm by tying string to each end to lengthen them, provided only the lace test specimen (6.1.1) rubs again
43、st the lace test specimen (6.1.2). 6.2 Methods 2 and 3 Cut six pieces of shoe lace each of length 300 mm 10 mm. If sufficient made shoe laces are available, cut each test specimen from a separate lace. For some equipment it is possible to use pieces of lace as short as 100 mm by tying string to each
44、 end to lengthen them, provided only the lace test specimen rubs against the test lace carrier (5.3). 7 Conditioning Store the shoe laces and the test lace carriers in a standard atmosphere in accordance with EN 12222 for at least 48 h before testing and carry out the test in this atmosphere. 8 Proc
45、edure 8.1 Method 1 8.1.1 Secure both ends of one of the pieces of lace (6.1.1) in a moveable clamp (5.1.2) so that it forms a loop of length approximately 2 x (D 160) mm. 8.1.2 Secure one end of a piece of the lace (6.1.2) in the corresponding stationary clamp (5.1.3). 8.1.3 Thread the free end of t
46、he piece of lace (6.1.2) through the loop formed by the piece of lace (6.1.1) in subclause 8.1.1. 8.1.4 Apply a tensioning force of 2,45 N 0,03 N to the free end of the piece of lace (6.1.2). 8.1.5 Fit a spacer (5.1.7) into the loop formed by the piece of lace (6.1.1) and slide it towards the point
47、of contact with the piece of lace (6.1.2) until the template (5.1.7) indicates that the tip of the loop of lace (6.1.1) forms an angle of 52,5 5,0 (see Figure 1). 8.1.6 Repeat the procedure in 8.1.1 to 8.1.5 for the other 5 pairs of test laces (6.1.1 and 6.1.2). For equipment with less than six test
48、 stations this will require steps 8.1.1 to 8.1.4 to be repeated until all six pieces have been tested.
