is held by AENOR, in collaboration with Technical Committee ISO/TC 216 "Footwear".
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by June 2005, and conflicting national standards shall be withdrawn at
the latest by June 2005.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

and United Kingdom.
1 Scope
This document specifies three test methods for determining the abrasion resistance 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
references, 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 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 specimens 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 lace 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.
5 Apparatus and materials
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 moveable 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 horizon
