Optical fibres - Part 1-32: Measurement methods and test procedures - Coating strippability
IEC 60793-1-32:2018 is intended primarily for testing either fibres as produced by a fibre manufacturer or subsequently overcoated (tight buffered) using various polymers. The test can be performed either on fibres as produced, or after exposure to various environments. This test applies to A1, A2, A3, B and C fibres with a nominal glass dimension of 125 µm. The object of this document is to establish uniform requirements for the mechanical characteristic – coating strippability. This test quantifies the force required to mechanically remove the protective coating from optical fibres along their longitudinal axis. This test is not intended as a means to maximize fibre strength after the coating is removed nor is it intended to specify the best conditions for field stripping of optical fibres. This test is designed for optical fibres having polymeric coatings with nominal outer diameters in the range of 200 µm to 900 µm. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: expansion of the range of coating dimensions applicable to the procedure detailed in this document to accommodate optical fibres with a 200 µm coating dimension.
Keywords: coating strippability, protective coating of optical fibres
Fibres optiques - Partie 1-32: Méthodes de mesure et procédures d'essai - Dénudabilité du revêtement
L'IEC 60793-1-32:2018 est destinée principalement aux essais des fibres, dès leur production par un fabricant de fibres, ou après revêtement ultérieur (revêtement protecteur serré) au moyen de divers polymères. L'essai peut être effectué sur des fibres issues de production, ou bien après exposition à divers environnements. Le présent essai s'applique aux fibres de types A1, A2, A3, B et C avec une dimension de verre nominale de 125 µm. L'objet du présent document est d'établir des exigences uniformes pour la caractéristique mécanique: dénudabilité du revêtement. Le présent essai permet de quantifier la force exigée pour retirer mécaniquement le revêtement de protection des fibres optiques le long de leur axe longitudinal. Cet essai n'est pas destiné à augmenter au maximum la résistance de la fibre après retrait du revêtement de protection, ni à spécifier les meilleures conditions pour le dénudage sur site de fibres optiques. Cet essai est conçu pour les fibres optiques ayant des revêtements polymères avec des diamètres extérieurs nominaux se situant dans la plage comprise entre 200 µm et 900 µm. Cette troisième édition annule et remplace la deuxième édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut la modification technique majeure suivante par rapport à l'édition précédente: élargissement de la plage des dimensions de revêtement applicables au mode opératoire présenté dans le présent document pour correspondre aux fibres optiques disposant d'une dimension de revêtement de 200 µm.
Mots-clés : dénudabilité du revêtement, revêtement de protection des fibres optiques

Coating strippability
1 Scope
This part of IEC 60793 is intended primarily for testing either fibres as produced by a fibre
manufacturer or subsequently overcoated (tight buffered) using various polymers. The test
can be performed either on fibres as produced, or after exposure to various environments.
This test applies to A1, A2, A3, B and C fibres with a nominal glass dimension of 125 µm.
The object of this document is to establish uniform requirements for the mechanical
characteristic – coating strippability. This test quantifies the force required to mechanically
remove the protective coating from optical fibres along their longitudinal axis.
This test is not intended as a means to maximize fibre strength after the coating is removed
nor is it intended to specify the best conditions for field stripping of optical fibres.
This test is designed for optical fibres having polymeric coatings with nominal outer diameters
in the range of 200 µm to 900 µm. Application of this method to fibres with outer coating
diameters outside the range of 230 µm to 930 µm is not recommended.
Warning – Fibres can fracture while being stripped and pierce skin and eyes. Use of
protective eyewear is recommended.
