Standard rounding rules apply. 2.5 LIGHT OUTPUT 2.5.1 Purpose To provide a procedure for the measurement of the total luminous flux (lumens) emitted by the device. 2.5.2 Power Supply All tests are con
4、ducted with fresh batteries or fully charged batteries/energy storage devices. 12V DC devices that are only tethered shall be powered with 13.8V DC using a power supply. Batteries used for testing and claim substantiation shall be of the same type and/or brand as those offered for sale with the prod
5、uct. If the product is sold without batteries and a light output claim is made, a specific battery type and chemistry shall be recommended with the package. The batteries recommended by the manufacturer are to be used for testing. Copyright 2009 by the National Electrical Manufacturers Association.
6、FL 1-2009 Page 9 2.5.3 Conditions Tests will be conducted at lab conditionssee clause 2.1.1. If the device offers multiple output levels, the light output will be measured at the maximum level or as otherwise identified. If the device has variable focusing or adjustable beam angle, the light output
7、will be measured at the focus level or beam angle that produces the maximum light output or as otherwise identified. 2.5.4 Apparatus An integrating sphere system with a spectroradiometer for spectral mismatch corrections and computing software to measure total light output shall be used. The minimum
8、 sphere diameter shall be equal to or greater than 3 times the maximum diameter of the port on the sphere where light enters it. 2.5.5 Test Equipment Sampling Calibration For each individual model, the test equipment shall be properly calibrated per the test equipment manufacturers instructions. The
9、 calibration procedure must include a lamp traceable to an NIST standard. 2.5.6 Procedures Devices are to be securely mounted against an external port adapter or placed inside the sphere. Exposure shall be set to produce test equipment manufacturers recommended detector saturation level. For each un
10、ique product color sample absorption correction must be completed. Measurements shall be taken at 30 s to 2 min of continuous operation after turning on the device. 2.5.7 Final Calculation Light Output is the average lumen value of the 3 samples. Round to whole numbers following standard rounding ru
11、les. 2.6 IMPACT RESISTANCE 2.6.1 Purpose To ensure structural integrity of hand-held/portable lighting devices under specified impact conditions. The test procedure provides specifications and methods that will ensure products meet a minimum standard of reliability as a result of impact testing. 2.6
12、.2 Conditions The test will be conducted at lab conditionssee clause 2.1.1. 2.6.3 Apparatus The apparatus shall consist of: An impact surface consisting of a minimum 4 cm nominal thickness of cured concrete. Impact area must be a minimum of 1 m x 1 m. A measuring device to confirm the drop test heig
13、ht. 2.6.4 Drop Test Products are dropped with all intended additions: batteries, elastic, tethers, hand straps, etc. Copyright 2009 by the National Electrical Manufacturers Association. FL 1-2009 Page 10 Drop height for product samples shall be 1 m minimum. Higher drop heights can be used for testin
14、g and product claims; however, any product claiming a drop height different than 1 m must meet all passing requirements listed below. Each sample is dropped 6 times using impact orientations that approximate a cube. Each sample must be released on each orientation of the approximated cube. Samples m
15、ust be marked prior to the drop test in a manner that can assure that all 6 drop orientations are tested. Samples shall be in the “off” position with batteries in place. The test sample is held in the desired orientation with its lowest part at the correct height. Drop the sample onto the impact sur
16、face. No additional impetus shall be given to the sample other than the acceleration due to gravity. The sample shall be allowed to come to rest after each drop. The test sample is examined after each drop. 2.6.5 Passing Criteria Dropped samples must not exhibit any cracks or breaks visible with nor
17、mal vision. The product must remain fully functional. Some reassembly is allowed provided that it is done without any tool or replacement components. Cosmetic defects such as scuffs, scratches, rubs, or abrasions will not be considered reasons for failure. 2.6.6 Impact Resistance Rating Test samples
18、 must pass a drop test from a minimum of 1 m in order for the impact resistance claim to be made. Ratings in excess of 1 m shall be reported with values rounded down to the nearest whole meter. All five test samples must pass the rated height. 2.7 ENCLOSURE PROTECTION AGAINST WATER PENETRATION RATIN
19、G 2.7.1 Purpose To ensure protection from damage under specific conditions of exposure to water. The procedure includes specifications and methods that will ensure the device meets minimum standards of reliability as a result of exposure to water under certain specific conditions. 2.7.2 Conditions A
20、ll tests will be conducted in lab conditionssee clause 2.1.1. Samples shall be in the “off” position with batteries in place. 2.7.3 Apparatus 2.7.3.1 Water Resistant An apparatus is used to spray water from all directions at specified water pressure, direction, and duration as described in ANSI/IEC
