5 Design

Protection sleeves are intended to meet the following requirements:

— Protection of cables and cable bundles

— Resistance to a hostile environment: abrasion, temperature, fire, arc, electromagnetic interferences

— Flexibility, minimum mass

— The minimum bend radius applicable shall be equal or smaller than the specified minimum bend radius for cables and cable bundles, as specified in EN 3197

— The sleeves are treated especially to reduce the absorption of water either from humidity or by capillary action when they are exposed to splashes of water

— The flammability, smoke emission and toxicity of all parts shall meet the requirements specified in the product standard

6 Definition drawings and mass

The general dimensions and mass of these sleeves are given in the product standards
