(Main)Footwear - Test methods for heels - Heel pin holding strength (ISO 19957:2004)
Footwear - Test methods for heels - Heel pin holding strength (ISO 19957:2004)
This European Standard specifies a test method for measuring the force required to pull a single heel pin out of a heel. This test method can be used to measure the heel pin holding strength of heel materials by using a standard heel pin and a method of insertion, or it can be used to assess the heel nailing of commercial production.
This test method is applicable to testing plastics and wooden heels for women's footwear. Heels composed of layers of fibreboard or leather and low plastics heels for men's footwear cannot be tested by this method.

Chaussures - Méthodes d'essai relatives aux talons - Résistance a l'arrachement de pointe a talon (ISO 19957:2004)
L'ISO 19957:2004 spécifie une méthode d'essai pour mesurer la force exigée pour retirer une pointe d'un talon. Cette méthode d'essai peut être utilisée pour mesurer la résistance à l'arrachement de pointes des matériaux de talon au moyen d'une pointe à talon et d'une méthode d'insertion normalisées, ou pour évaluer le clouage des talons de production commerciale.
La présente méthode d'essai est applicable à l'essai des talons en plastique et en bois pour chaussures pour femmes. Les talons composés de couches de panneaux de fibres ou de cuir et les talons bas en plastique pour chaussures pour hommes ne peuvent être mis à l'essai par cette méthode.

1 Scope
This European Standard specifies a test method for measuring the force required to pull a single heel pin out of a
heel. This test method can be used to measure the heel pin holding strength of heel materials by using a standard
heel pin and a method of insertion, or it can be used to assess the heel nailing of commercial production.
This test method is applicable to testing plastics and wooden heels for women’s footwear. Heels composed of
layers of fibreboard or leather and low plastics heels for men’s footwear cannot be tested by this method.
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 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.
heel pin holding strength
force required to pull a standard pin out of the heel material divided by the effective length of pin buttressing in the
material, expressed as N/mm
4 Apparatus and material
4.1 The following apparatus and material shall be used:
4.2 Tensile testing machine complying with the requirements of EN ISO 7500-1 class 2, with a range of
approximately 0 N to 2000 N and a constant rate of speed of 40 mm/min ± 10 mm/min.
NOTE A constant rate of traverse tester can be used if this is of a type where increase of load produces an appreciable
movement of the load jaw (e.g. a pendulum tester). Its rate of traverse should be set to give on average the specified rate of
loading over the whole range for zero jaw separation. This approximation to constant rate of loading is acceptable because the
amount of jaw separation in the test is small before the maximum load is reached.
4.3 Small clamp or slotted hook, which can be attached to one jaw of the tensile testing machine via a flexible
coupling.
4.4 Commercial heel nailing machine.
4.5 Standard heel pin (see Figure 1), with the following dimensions:
a) length:
18 mm ± 0,5 mm;
b) diameter over the buttress ridges: 1,9 mm, minimum;
c) number of complete formed buttress pressure flanks (the side of
13 minimum;
the buttress which is nearly at right angles to the pin shaft):
d) distance from point to the base of the first fully formed buttress
12 mm, minimum.

5.1 Number of test specimens
For assessing the heel pin holding properties of a heel material, prepare and test three heels each containing six
inserted pins, or, if it is not possible to insert six pins, four heels each containing four pins. When testing heels
already attached to shoes, where possible, also prepare three containing
