Impose horizontal pull of tangential direction on any point of the edge of the revolving plate, till it is about to be initiated. Record the revolving force F. Multiply the revolving force F by the semidiameter of the revolving plate, the result is torque. 6.6.8.2 Static load test of unilateral revolving plate Impose 45 N of load on any central line under a distance of 100 mm from the edge, maintain for 10 s. After imposing for 10 times, examine the revolving plate. 6.6.8.3 Vertical impact strength test of revolving plate Let a desktop impactor that complies with the stipulation in GB/T 10357.1 fall freely from a vertical height of 140 mm (from the bottom of the impactor to the revolving plate). Impact the central part of the revolving plate for 1 time. After the test, check the revolving plate. 6.7 Adhesive Strength Test of Glass and Metal Connecting Plate Use a preset torque wrench, then, load 40 Nm of torque along the tangential direction of the diameter of the revolving plate; maintain for 10 s. Observe whether the agglutinate parts are separated. Within an inspection cycle, randomly draw 2 samples from recently produced products. one of them shall be submitted for inspection, and the other one shall be sealed up for safekeeping. 7.3.3 Inspection procedure Inspection procedure shall comply with the principle of minimizing the influence on the accuracy of the remaining inspection items. 7.4 Determination of Inspection Result When a product is qualified in all the basic items and disqualified in < 4 general items, this product shall be determined as qualified. When a product cannot satisfy the requirements of qualified product, it shall be determined as disqualified. 7.5 Re-inspection Rules When a product is determined as disqualified in model inspection, the sealed-up sample can be used for re-inspection. In re-inspection, disqualified items and items that are not inspected because of sample damage shall be inspected. Appraise it in accordance with the stipulation in 7.4.Indicate “re-inspection” in the inspection result.8 Marking, Instruction for Use, Packaging,Transportation and Storage 8.1 Marking Product marking shall at least include the following content. a) Product name, specification and model number; b) Name of main materials; serial number of standard; c) Certificate of inspection; date of production; d) Chinese name and address of manufacturer. 8.2 Instruction for Use Instruction for use that complies with GB 5296.6 shall be provided; it shall at least include the following content. a) Product name, specification, model number and serial number of standard; b) Main materials (glass) of product; c) Limit of hazardous substances in wood pieces; ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
