This International Standard is part of a standard series dealing with insulating sleeving for electrical purposes. The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1); Part 2: Methods of test (IEC 60684-2); Part 3: Specifications for individual types of sleeving (IEC 60684-3). This standard contains two of the sheets which belong to Part 3 of this series: - Sheet 116: Extruded polychloroprene, general purpose, thin wall. - Sheet 117: Extruded polychloroprene, general purpose, thick wall. These sleevings are used in the field of connection technology, for the manufacture of electronic components, for insulation of electronic and electric components and for insulation and mechanical protection in the automotive industry. This part of IEC 60684 gives the requirements for non-heat-shrinkable sleeving, extruded from compounds based on polychloroprene elastomer. This sleeving has been found suitable for temperatures up to 95 °C. Sleeving of this type is normally available with internal diameters up to 25 mm, and in the following opaque colours: black, brown, red, orange, yellow, green, blue, violet, grey, white and pink. Sizes or colours other than those specifically listed in this standard may be available as custom items. These items shall be considered to comply with this standard if they comply with the other property requirements listed in Table 2. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in the application and not based on the specification alone. The responsible committee is DKE/K 181 "Feste elektrische Isolierstoffe" (AK 181.0.5 "Isolierschläuche") ("Solid electrical insulating materials" (WG 181.0.5 "Insulating sleeving")) of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
