cracks are present in any plastic cover or retainer of rigid item, the complete plastic part shall then be removed and the remaining assembly shall then be assessed against its continued security. If the remaining assembly is still secure, or no visible cracks are present, it will then be further assessed against the test requirements specified in paragraphs 6.2.2., 6.2.3. and 6.4.

         6.2.2. Buckle

         6.2.2.1. The buckle shall be so designed as to preclude any possibility of incorrect use. This means, inter alia, that it must not be possible for the buckle to be left in a partially‑closed condition. The procedure for opening the buckle must be evident. The parts of the buckle likely to contact the body of the wearer shall present a section of not less than 20 cmP2P and at least 46 mm in width, measured in a plane situated at a maximal distance of 2.5 mm from the contact surface. In the case of harness belt buckles, the latter requirement shall be regarded as satisfied if the contact area of the buckle with the wearer's body is comprised between 20 and 40 cm2.

         6.2.2.2. The buckle, even when not under tension, shall remain closed whatever the position of the vehicle. It shall not be possible to release the buckle inadvertently, accidentally or with a force of less than 1 daN. The buckle shall be easy to use and to grasp; when it is not under tension and when under the tension specified in paragraph 7.8.2. below, it shall be capable of being released by the wearer with a single simple movement of one hand in one direction; in addition, in the case of belt assemblies intended to be used for the front outboard seats, except in these harness belts, it shall also be capable of being engaged by the wearer with a simple movement of one hand in one direction. The buckle shall be released by pressing either a button or a similar device. The surface to which this pressure is applied shall have the following dimensions, with the button in the actual release position and when projected into a plane perpendicular to the button's initial direction of motion: for enclosed buttons, an area of not less than 4.5 cmP2P and a width of not less than 15 mm; for non‑enclosed buttons, an area of not less than 2.5 cmP2P and a width of not less than 10 mm. The buckle release area shall be coloured red. No other part of the buckle shall be of this colour.  When the seat is occupied, red warning light in any part of the buckle is permitted if it is switched off after the occupant has buckled.

         6.2.2.3. The
