6 WDUS 1796:2017 Foreword Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade, Industry and Cooperatives established under Cap 327, of the Laws of Uganda, as amended. UNBS is mandated to coordinate the elaboration of standards and is (a) a member of International Organisation for Standardisation (ISO) and (b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and (c) the National Enquiry Point on TBT Agreement of the World Trade Organisation (WTO). The work of preparing Uganda Standards is carried out through Technical Committees. A Technical Committee is established to deliberate on standards in a given field or area and consists of key stakeholders including government, academia, consumer groups, private sector and other interested parties. Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the general public for comments. The committee reviews the comments before recommending the draft standards for approval and declaration as Uganda Standards by the National Standards Council.

22 d) Filing mechanism. The filing mechanism shall be of the multi-pin type in the case of a multi-section cabinet (see ) and of either the two-pin or the multi-pin type in the case of a single-section cabinet (see (c)), and shall 1) be such that all filing and sorting operations can be carried out easily by an operator standing in front of the cabinet; 2) allow plans to be removed from or inserted into any section or in any location among the filed plans in the cabinet without necessitating the removal of any other plan; 3) support plans on filing pins that are firmly secured in position in the cabinet and that pass through holes in the top edges of the plans (the plans being provided for that purpose with an acceptable reinforcement that is readily obtainable from the supplier of the cabinet); 4) allow plans to be closely packed parallel to each other (in vertical planes); 5) so provide and be capable of maintaining a sorting position that filed plans can be manipulated and sorted on the filing and sorting pins before a plan is inserted or extracted. In the sorting position, the filing and sorting pins shall overlap by at least 25 mm (in the case of a multipin mechanism) or so engage or mate (in the case of a two-pin type mechanism) that plans can be moved smoothly in both directions across the junction. The mechanism shall be such that, by disengaging a safety stop or by opening a front panel, it is possible to create and maintain, during a filing operation, a gap between the sorting and the filing pins that is wide enough to allow the removal or insertion of a plan in the selected position without the risk of damage to the plan. e) Filing index. A cabinet shall have a filing index in an acceptable holder that is fixed to the casing or lid in a position convenient for the operator. The index space provided shall be commensurate with the maximum capacity of the cabinet. f) Stability.

Joints shall be made only on the edges of the casing and shall be flanged to a width of at least 12 mm and then welded, brazed, or riveted. No bolts shall be used except in positions where the bolts are inaccessible from the outside when the cabinet is locked and where they will not damage plans during or after filing. The casing shall have a kickplate of height at least 60 mm. The kickplate shall be integral with the bottom of the casing and shall be stiffened as necessary. If the casing is of double-wall construction it shall be closed on the edges, and all edges (at openings and of lids) shall be bent into a double return of width at least 12 mm and depth at least 10 mm or into an inverted Z. Joints at corners shall be welded and shall be smoothly dressed off. The casing shall have a rigid removable panel or a door that is so positioned as to allow the easy recovery of any plans that may have dropped to the bottom of the filing space. The panel or door, if not of double wall construction, shall be so reinforced as to maintain its shape and alignment. The casing shall be so constructed that L i d s a) moving parts of the filing mechanism that are built into it can be easily exposed for inspection, maintenance, and repair purposes; b) the cabinet will pass through a standard single-door opening and if, for this purpose, parts of the cabinet are detachable, 1) it shall not be possible to detach them until the cabinet has been unlocked, and 2) it shall be easy for a layman to detach and reassemble them. The lid(s) shall be of mild steel sheet of thickness at least 1,0 mm or of an equivalent acceptable material, and the constructional requirements for the removable panel or door (see ) shall apply Stays Lids, doors, and hinged panels shall be fitted with rigid folding stays or spring-loaded devices that are capable of maintaining them in the open position. Stays and spring-loaded d e v i c e s shall be of corrosion-resistant metal or shall have a corrosion-resistant finish. Stays and springloaded devices shall be such that lids, doors, and hinged panels are easily operable by a person of less than average physical strength and shall be so designed and made as to UNBS 2017 All rights reserved 17

Pins shall be circular or oval in section or shall have radiused edges and, unless of intrinsically corrosion-resistant material, shall be chromium or cadmium-plated. In the case of a multi-pin cabinet, the centre-to-centre distances between filing pins and between sorting pins shall be identical and shall not exceed 150 mm. The positioning of each set of pins shall be such that, in the closed position, each sorting pin is midway between adjacent filing pins. In the case of a two-pin cabinet, the sorting pins shall telescope smoothly into the filing pins or shall be such as to form an unvarying cross-section at the lap when the cabinet is closed. Pins shall be either slightly convex upwards or straight. The strength of filing and sorting pins and their mountings shall be such that, when the pins are loaded to capacity, they are capable of supporting filed plans with the filing section fully extended, and the filing gap open Alignment and strength of filing pins and sorting pins a) When a cabinet is tested in accordance with 8.8, any deviation in the horizontal alignment of the upper surfaces of the filing pins and sorting pins in the cabinet or section of the cabinet that contains more than two filing pins shall not exceed 1,5 mm, and their mountings shall reveal no deformation or damage. b) When a cabinet is tested in accordance with 8.9, the difference between the two measurements on each pin shall not exceed 1,5 mm and at the conclusion of the test the pins shall comply with (a) above and, in the case of telescoping pins, the telescoping action shall work smoothly Lateral filing cabinets Design and dimensions General Lateral filing cabinets shall be either single units or composite units, as specified by the purchaser, and shall be designed for the storage of letters or legal documents, computer print-outs, disc packs, tape reels, and seals and suspension binders.
