Test on gases evolved during combustion of materials from cables - Part 2: Determination of acidity (by pH measurement) and conductivity

IEC 60754-2:2011 specifies the apparatus and procedure for the determination of the potential corrosivity of gases evolved during the combustion of materials taken from electric or optical fibre cable constructions by measuring the acidity (pH) and conductivity of an aqueous solution resulting from the gases evolved during the combustion. The general method specified in this standard is intended for the testing of individual components used in a cable construction. Formulae are given for the calculation of a weighted value for a combination of materials found in a specified cable. The use of this method will enable the verification of relevant requirements for either individual components or combined components of a cable construction stated in the appropriate cable specification. A simplified method is included for the testing of individual components where it is required only to demonstrate compliance with a stated performance requirement for quality control purposes. The significant technical changes with respect to the previous edition are as follows: - improved definition of safety requirements relating to capture of gases; - introduction of guidance on the preparation of test specimens for more even combustion; - better expression of tolerances and precision; - clarification of the conductivity and acidity functions; - improved definition of the heating procedure; - greater precision in the definition of the test temperature for the determination of pH value and conductivity; - correction of the formulae for the calculation of the test results. IEC 60754-2:2011 has the status of a group safety publication in accordance with IEC Guide 104.

Prüfung der bei der Verbrennung der Werkstoffe von Kabeln und isolierten Leitungen entstehenden Gase - Teil 2: Bestimmung der Azidität (durch Messung des pH-Wertes) und Leitfähigkeit

Essai sur les gaz émis lors de la combustion des matériaux prélevés sur câbles - Partie 2: Détermination de la conductivité et de l‘acidité (par mesure du pH)

La CEI 60754-2:2011 décrit l'appareillage et la procédure d'essai pour déterminer le potentiel de corrosivité des gaz émis pendant la combustion de matériaux prélevés sur un câble électrique ou un câble à fibre optique en mesurant l'acidité (pH) et la conductivité d'une solution aqueuse obtenue à partir des gaz dégagés pendant la combustion. La méthode générale décrite dans cette norme est destinée à l'analyse des composants individuels utilisés dans la construction d'un câble. Des formules de calcul sont données pour le calcul d'une valeur pondérée lors de la combinaison de matériaux pesés provenant d'un câble spécifié. L'emploi de cette méthode d'essai permettra de vérifier les exigences appropriées soit pour les composants individuels du câble, soit pour la combinaison des composants rentrant dans la construction du câble, exigences établies dans la spécification appropriée du câble. Une méthode simplifiée est incluse pour l'essai de composants individuels lorsqu'il est exigé seulement pour démontrer la conformité à une exigence de performance exigée dans le cadre de contrôle de qualité. Les modifications techniques importantes par rapport aux publications antérieures sont les suivantes: - une amélioration de la définition des exigences de sécurité relatives au piégeage des gaz; - introduction de recommandations pour la préparation des éprouvettes d'essai pour une meilleure combustion; - une meilleure expression des tolérances et précisions; - clarification des fonctions du ph et de la conductivité; - amélioration du mode opératoire pour le chauffage; - meilleure précision de la définition de la température d'essai pour la détermination du pH et de la conductivité; - correction de la formule de calcul des résultats d'essais. Elle a le statut d'une publication groupée de sécurité conformément au Guide CEI 104.

Ugotavljanje nastajanja plinov pri gorenju kabelskih materialov - 2. del: Ugotavljanje kislosti (z merjenjem pH) in prevodnosti (IEC 60754-2:2011)

Standard EN-IEC 60754-1 določa napravo in postopek za ugotavljanje morebitne eksplozivnosti plinov, nastalih pri gorenju materialov iz konstrukcij električnih ali optičnih kablov, z meritvijo stopnje kislosti (pH) in prevodnosti vodne raztopine, ki sta posledica plinov, nastalih med gorenjem. Splošna metoda, določena v tem standardu, je namenjena preskušanju posameznih komponent, ki se uporabljajo pri izdelavi kablov. Na voljo so formule za izračun ovrednotene vrednosti za kombinacijo materialov v določenem kablu. Uporaba te metode bo omogočila preverjanje ustreznih zahtev za individualne komponente ali združene komponente kabelske sestave, navedene v ustrezni kabelski specifikaciji. Poenostavljena metoda je vključena v preskušanje posameznih komponent, kjer je zahtevan le prikaz skladnosti z navedeno zahtevo glede zmogljivosti.
