This standard replaces the standard previously issued as follows: - QB/T 2189-1995. Hardware for furniture -- Cup hinge1 ScopeThis standard specifies the terms and definitions, requirements, test methods, inspection rules, markings, instructions for use, packaging, transportation, storage of cup hinges for furniture. This standard applies to cup hinges for furniture. Other hinges may refer to this standard.2 Normative referencesThe following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard. QB/T 3826 Corrosion-resistant testing method of the metal deposits and conversion coatings for the light industrial products - Neutral salt spraying test (NSS)3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Catch device A device that keeps or attaches a door in a certain position. Note: The open of catch device does not require auxiliary actions, such as a magnetic stop OR a mechanical device that automatically closes. 3.2 Damper mechanism A mechanical device that slowly stops the door from moving. instructions for use provided. If no instructions for installation, assembly or adjustment are provided, it shall install or assemble the cup hinge in a way, that is the most unfavorable for the cup hinge; meanwhile it shall record it in the inspection report. Cup hinge's fittings shall be tightened before the test. If there is no manufacturer's special instruction, the fittings shall, during the test, not be re-tightened. If, for the purpose of testing the performance of the cup hinge in the worst case, it is necessary to change the cup hinge device, it shall be recorded in the inspection report. The test shall be carried out at an indoor temperature of 15 °C ~ 25 °C. If the cup hinge contains parts which are made of hygroscopic plastic (such as polyamide), the cup hinge shall, before the test, be conditioned at a temperature of (23 ± 5) °C and a relative humidity of (50 ± 5)% for 7 days. Before the test, it shall thoroughly inspect the cup hinge and its accessories; record the defects of the cup hinge and its components, to distinguish from the defects caused by the test. 5.2 Test equipment Unless otherwise specified, any applicable test device can be used for the test; the test result does not depend on the device itself. 5.2.1 Loading In the static load test, the loading speed shall be as slow as possible, to ensure that the additional dynamic load is negligible. Unless otherwise specified, each load applied shall be maintained for 10 s ~ 15 s. In the durability test, the loading speed shall ensure that no dynamic heating will occur. Note: The applied force can be replaced by mass. The conversion relationship is that: 10 N is equivalent to 1 kg. 5.2.2 Accuracy Unless otherwise specified, use the following measurement accuracy: - Loading force: ±5% of the rated value; - Speed: ±5% of the rated value; - Mass: ±1% of rated value; - Size: ±1 mm; The door can be opened and closed manually. The opening and closing time is 3 s ~ 5 s, respectively. At the end of test, unload and inspect it. 5.5.3 Horizontal static load This test is only applicable to cup hinges, which have a maximum opening angle of less than 135°. In the fully open position of the door, apply the load specified in Table A.2 of Appendix A on the horizontal centerline, which is 100 mm away from the side of the cup hinge, in the direction perpendicular to the plane of the door, as shown in Figure 4. The test is carried out 10 times. At the end of test, unload and inspect it. 5.5.4 Durability Suspend two weights, each of which has a mass of 1 kg, on the vertical centerline of each side of the door (see Figure 6). According to the number of cycles specified in Table A.2 of Appendix A, open the door. After the maximum opening angle reaches 130°, close the door. Make it reciprocate back and forth. When the door is in the open position, there shall be no internal resistance. At the end of test, make inspection. If the cup hinge does not have a damper mechanism or catch device, during the test, the door shall be opened and closed slowly. The opening time and closing time of the door in each cycle is about 3 seconds. The recommended maximum frequency is 6 times/min. If the cup hinge has a damper mechanism or catch device, THEN for each reciprocation, the damper mechanism or catch device shall be able to perform its function correctly.6 Inspection rules6.1 Type inspection items All items in Chapter 4 of this standard are type inspection items. 6.2 Type inspection shall be carried out in one of the following situations: a) During formal production, inspection shall be carried out regularly; the inspection period is generally 1 year; b) When the raw and auxiliary materials AND their production processes undergo major changes; c) When the production is resumed after long term suspension of production; d) Trial type appraisal of new or old products; e) When the quality supervision agency proposes type inspection requirements. 6.3 Sampling rules Within one inspection cycle, randomly select 12 samples from the recently produced products, wherein 6 samples are submitted for inspection AND 6 are retained for reference. 6.4 Inspection procedures The test is carried out in accordance with the steps which are specified in this standard. 6.5 Judgment of inspection results When the results of all inspection items meet the requirements specified in this standard, the product is determined to be a qualified product. Those failing to meet the requirements of qualified products are disqualified products. 6.6 Re-inspection rules If the product fails in the type inspection, it may use the retained standby sample for re-inspection. It shall follow the provisions of 6.5 to make judgement. In the inspection report, indicate "qualified in reinspection" or "disqualified in reinspection".7 Markings, instructions for use, packaging,transportation and storage 7.1 Markings The product marking shall include at least the following content: a) Product name, specification and model; b) The number of implemented standard; c) Inspection certificate and production date; d) The Chinese name and address of the manufacturer. 7.2 Instructions for use Product's instruction for use should be compiled with reference to GB 5296.6. The content shall at least include: a) Product name, specification model, number of implemented standard, production date and grade; b) The name of the main raw and auxiliary materials of the product, as well as the location of use; c) Main technical parameters (including maximum opening angle and hinge cup's diameter, etc.); d) The type of furniture to which the product is applicable (such as household or commercial); e) Technical requirements and considerations for product installation and adjustment; f) Product's use method and considerations; g) Product failure analysis and troubleshooting, maintenance methods. 7.3 Packaging Products shall be packaged, to prevent bumps, scratches, stains, or damages. 7.4 Transportation and storage Products shall be stacked flat during transportation and storage.
