Foreword
This document (EN ISO 19958:2004) has been prepared by Technical Committee CEN /TC 309 "Footwear", the
secretariat of which 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by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by
March 2005.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
1 Scope
This European Standard specifies a test method for measuring the force required to detach the top piece from the
underside of the shoe heel. The test is applicable to heels with the top piece already attached which have been
removed from complete shoes, to heels alone with the top piece attached and, in some instances, to heels with
separate push-in top pieces. All heels, except reinforced slender heels with top pieces attached by steel spigots
and built stacked heels, can be tested by this method.
2 Normative references
The following referenced document is 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 ISO 7500-1 Metallic materials - Verification of static uniaxial testing machines - Part 1: Tension/compression
testing machines (ISO 7500-1:1999).
3 Terms and definitions
For the purposes of this European Standard, the following term and definition apply.

top piece retention strength
maximum force, expressed in Newton, required to pull off a top piece from the heel
4 Apparatus and materials
4.1 The following apparatus and materials shall be used.
4.2 Tensile testing machine, complying with the requirements of EN ISO 7500-1 class 2, with a range of 0 N to
1000 N and a constant-rate-of-loading of 15 N/s ± 5 N/s. A constant-rate-of-traverse tester, for which increase of
force produces an appreciable movement of the load jaw (e.g. a “pendulum” tester”), may be used if the rate of
traverse is set to give, on average, the specified rate of force application when a test is carried out. Alternatively, a
constant-rate-of-traverse tester for which there is little movement on the load jaw may be used if the top piece is
attached to one jaw of the tester via one or more extensible cords which are substantially elastic over the force
range of the test and the rate of traverse is adjusted until the specified rate of force application is obtained.
4.3 Drill, with twist drill beats of suitable sizes (see 5.2.1.4 and 5.2.1.5).
4.4 Bolt, of size M 4 or size M 3 for slender heels, and preferably of length 40 mm or more with a small metal
ring or loop attached to its head by brazing. If only low heels are b
