Anotation

IEC 60695-10-2:2014 specifies the ball pressure test as a method for evaluating the softening temperature and accelerated material flow under load of polymeric materials and parts of end products in their ability to resist abnormal heat. It is applicable to the materials used in electrotechnical equipment, subassemblies and components, and to solid electrical insulating materials except ceramics. The Ball Pressure test method is not appropriate for certain elastomers, foamed materials, and other materials that tend to be soft at room temperature. Product Committees are encouraged to evaluate these materials using other methods such as IEC 60695-10-3. This third edition cancels and replaces the second edition of IEC 60695-10-2 published in 2003. It constitutes a technical revision. The main changes with respect to the previous edition are as follows: - The addition of an introduction introduces the user to the basic guidance documents published by TC 89, - Addition of a reference to IEC Guide 104 and ISO/IEC Guide 51 in the Scope, - Additional relevant Terms and Definitions in new Clause 3, - 5.2: Additional requirements to the test specimen support at the suggestion of IECEE-CTL to improve reproducibility, - 5.3: Clarification of heating oven requirements at the suggestion of IECEE-CTL to improve reproducibility, - 5.4: Specification of minimum resolution consistent with method requirements for optical measurement instrument, - New Test Procedure in Clauses 6 and 8 which introduces separate methods for End Product proof testing (Method A) and material performance testing (Method B) and - Updated Clause 11 Test Report to be consistent with other IEC 60695 documents. Key words: Abnormal heat, Ball pressure test method, Fire hazard IEC 60695-10-2:2014 specifie lessai a la bille comme methode dessai permettant devaluer la temperature de ramollissement et le flux accelere sous charge des polymeres et parties de produits finis, afin de verifier leur aptitude a resister a un echauffement anormal. Elle est applicable aux materiaux utilises dans les materiels, sous-ensembles et composants electrotechniques, et aux materiaux isolants electriques solides a lexception des ceramiques. Lessai a la bille nest pas approprie a certains elastomeres, materiaux alveolaires et autres materiaux qui presentent une tendance au ramollissement a la temperature ambiante. Les comites de produits sont encourages a evaluer ces materiaux en appliquant dautres methodes, telles que celles de lIEC 60695-10-3. Cette troisieme edition annule et remplace la deuxieme edition de lIEC 60695-10-2 publiee en 2003. Elle constitue une revision technique. Les principales modifications apportees par rapport a ledition precedente sont enumerees ci-dessous: - Ajout dune introduction qui renseigne lutilisateur sur les documents directeurs de base publies par le CE 89, - Ajout dune reference au Guide IEC 104 et au Guide ISO/IEC 51 dans le Domaine dapplication, - Ajout dun nouvel Article 3 comportant des termes et definitions pertinents, - 5.2: Exigences supplementaires applicables au support deprouvette dessai sur proposition du IECEE-CTL, afin dameliorer la reproductibilite, - 5.3: Clarification des exigences applicables a letuve sur proposition du IECEE-CTL, afin dameliorer la reproductibilite, - 5.4: Specification dune resolution minimale coherente avec les exigences relatives aux methodes utilisant un instrument de mesure optique, - Nouveau mode operatoire dessai aux Articles 6 et 8, qui presente des methodes distinctes pour les essais de validite de produit fini (Methode A) et les essais de performance des materiaux (Methode B), et - Mise a jour de lArticle 11 Rapport dessai pour alignement avec les autres documents de lIEC 60695.
