5.2.8 Restraint 5.2.8.1 General Type 1 and Type 2 knee protectors that are worn on the body shall be provided with a restraint system that ensures that they are correctly placed for working in the kneeling position. This restraint may be achieved using integral straps with buckles, touch and close fasteners, separate “harness” or other items of protective equipment or clothing. The manufacturer shall give details of how adequate restraint of the knee protectors may be achieved in the Information supplied by the manufacturer. 5.2.8.2 Type 1 Knee protectors Knee protectors that fasten around the leg shall be provided with straps at least 40 mm wide. Straps shall be continuously adjustable. No part of a strap shall pass within 10 mm of the centre of the back of the knee when the protector is on a leg and the knee is bent. Assessment shall be made according to 6.4. The restraint system for the knee protectors shall be assessed as described in 6.8.1. The knee protector shall not be displaced by more than 5 cm, when the test force is applied and shall return to within 2 cm of its initial position when the force is removed. The force to be resisted shall be (10 ± 1) N. If knee protectors are restrained by a system that does not use straps the manufacturer shall demonstrate that venous drainage is unlikely to be impaired. (See informative Annex A) 5.2.8.3 Type 2 Knee protectors Knee protectors in trousers shall be held in closed pockets or attached to the trousers in another way. If not in pockets they shall not be removable by a force of (100 ± 5) N as described in 6.8.2. SIST EN 14404:2005
