1.3  Terms and definitions
For the purpose of this Standard the following definitions apply. 1.3.1 accuracy degree of closeness to the true value or the specified value of whatever dimension is being measured, or force applied 1.3.2 clear space internal height of a drawer defined by the height of a box that just allows the drawer to be closed 1.3.3 damper component or function of a component that absorbs energy and cushions the opening or closing of a door, drawer or flap Note 1 to entry: See also self-closing devices (1.3.21), self-assist closing device (1.3.22), self-opening devices (1.3.23) and self-assist opening device (1.3.24). 1.3.4 deflection maximum displacement of a component measured under load at the time specified in the test Note 1 to entry: The residual or permanent effect of the load or forces applied is deformation. 1.3.5 deformation permanent change in shape or size due to the application of loads or forces 1.3.6 drawer box like storage compartment without a lid and made to slide horizontally in and out of a unit with the aid of a runner and fitted with an out‑stop Note 1 to entry: See also tote (1.3.32) and pencil drawer (1.3.16). 1.3.7 durability loading reiterated application to the unit in a steady and gradual manner, of the load which is likely to occur most frequently 1.3.8 extendible member flat or near flat shelf‑like component that slides in and out of a unit with the aid of a runner and fitted with an out‑stop 1.3.9 flap door hinged at either the top or bottom that is opened by pulling up from the bottom or down from the top 1.3.10 guide channel or similar in or on which a tote slides for storage and removal from a unit 1.3.11 headroom an unrestricted space of less than 1 050 mm above the floor of the unit Note 1 to entry: See also unrestricted headroom (1.3.35). 1.3.12 internal volume volume of a drawer defined by the size of a box that touches both sides, both ends and a height that just allows the drawer to be closed 1.3.13 lock device that prevents a latch from opening without a key, code or similar1.3.14 latch an automatic or manual device that keeps a door, drawer or flap in an open or closed position, but not locked Note 1 to entry: An automatic latch requires a force in the direction of travel to actuate. Note 2 to entry: A manual latch requires at least one hand motion in other than the direction of travel to actuate. Note 3 to entry: Gas struts are not considered as latches. 1.3.15 out-stop physical stop that prevents a drawer or extendible member from being fully removed from its track accidentally Note 1 to entry: See also tote-stop (1.3.33). 1.3.16 pencil drawer drawer with a clear space height of between 20 mm and 50 mm and a functional load at “Normal” level as specified in Table 7.2(B) of less than 4 kg Note 1 to entry: Unless otherwise stated, test pencil drawers as drawers. Note 2 to entry: See also tote (1.3.32) and drawer (1.3.6). 1.3.17 precision degree to which repeated measurements show the same results Note 1 to entry: Precision is usually expressed as a ± % about the true value or the specified value of whatever dimension is being measured, or force applied. 1.3.18 roll front — horizontal vertically mounted segmented door that is pulled horizontally to close and pushed horizontally to open Note 1 to entry: A horizontal roll front is usually guided in horizontally mounted tracks at the top and bottom of the door.
