This outline of investigation provides requirements for construction and testing of outdoor patio furniture such as tables, tables with umbrellas, chairs, multi-seat products, loveseats, benches, hanging chairs or swings and chaise lounge chair. Indoor furniture or outdoor furniture with electrical components should reference the Standard for Household and Commercial Furnishings, UL 962.
1. Unless otherwise specified, tolerances shall be: a) Test Weights, Forces, Velocities, Time, and Cycle requirements are minimums; b) Linear measurements, ± 1.5 mm (1/16 in); c) Angles, ± 5 degrees; and d) Level, within 5 mm per meter (0.06 in per linear foot) or ± 0.3 degrees. 2. Test weights, forces, dimensions, angles, times, rates and velocities used to perform the test shall be targeted at the nominal values specified and shall be subject to the above tolerances. Devices used to calibrate test devices and/or machines shall be calibrated to one-fourth of the above tolerance, with the exception of Level, which shall be calibrated to one-half.
1. 除非另有規定,采用以下公差: a) 重量,力,速度,時間,次數的規定為最低要求 b) 長度測量:± 1.5 mm (1/16 in) c) 角度,± 5 degrees d) 平準度,5mm/米 或± 0.3 degrees 2. 用于計量測試設備的儀器的校準精度至少為上述公差的四分之一,但校準平準度的儀器校準精度應至少為上述公差的二分之一.
