  "heading": "Verification tolerances",
  "text": "(1) The verification tolerances set out in Table 14 must be used only by the market surveillance authority and only for the purposes of this Schedule.\n(2) The supplier must not use the verification tolerances—\n(a) as allowed tolerances to establish the values in the technical documentation;\n(b) in order to interpret those values with a view to achieving compliance; or\n(c) to communicate better performance.\nTable 14\nVerification tolerances\nParameter\nVerification tolerances\nFull-load on-mode power Pon (W):\nPon ≤ 2W\nThe determined value must not exceed the declared value by more than 0.20W.\n2W < Pon ≤ 5W\nThe determined value must not exceed the declared value by more than 10%.\n5W < Pon ≤ 25W\nThe determined value must not exceed the declared value by more than 5%.\n25W < Pon ≤ 100W\nThe determined value must not exceed the declared value by more than 5%.\n100W < Pon\nThe determined value must not exceed the declared value by more than 2.5%.\nDisplacement factor (0-1)\nThe determined value must not be less than the declared value minus 0.1 units.\nUseful luminous flux Φuse (lm)\nThe determined value must not be less than the declared value minus 10%.\nStandby power Psb and networked standby power Pnet (W)\nThe determined value must not exceed the declared value by more than 0.10W.\nCRI and R9 (0-100)\nThe determined value must not be less than the declared value by more than 2.0 units.\nFlicker (Pst LM) and stroboscopic effect (SVM)\nThe determined value must not exceed the declared value by more than 0.1, or by more than 10% if the declared value is more than 1.0.\nColour consistency (MacAdam ellipse steps)\nThe determined number of steps must not exceed the declared number of steps. The centre of the MacAdam ellipse must be the centre declared by the supplier with a tolerance of 0.005 units.\nBeam angle (degrees)\nThe determined value must not deviate from the declared value by more than 25%.\nTotal mains efficacy ηTM (lm/W)\nThe determined value (quotient) must not be less than the declared value minus 5%.\nLumen maintenance factor (for LED and OLED)\nThe determined XLMF% of the sample must not be less than XLMF, MIN% in accordance with the test in Schedule 5.\nSurvival factor (for LED and OLED)\nAt least 9 light sources of the test sample must be operational after completing the endurance test in Schedule 5.\nExcitation purity (%)\nThe determined value must not be less than the declared value minus 5%.\nCorrelated colour temperature (K)\nThe determined value must not deviate from the declared value by more than 10%.\nPeak luminous intensity (cd)\nThe determined value must not deviate from the declared value by more than 25%.\n(3) For light sources with linear geometry which are scalable but of very long length, such as LED strips or strings, verification testing must consider a length of 50 cm, or, if the light source is not scalable there, the nearest value to 50 cm. The light source manufacturer or importer must indicate which separate control gear is suitable for this length.\n(4) When verifying if a product model is a light source, the market surveillance authority must compare the measured values for—\n(a) chromaticity coordinates (x and y);\n(b) luminous flux;\n(c) luminous flux density; and\n(d) colour rendering index,\ndirectly with the limit values set out in the definition for light source in regulation 2(1), without applying any tolerances.\n(5) If any of the 10 units in the sample satisfies the conditions for being a light source, the product model must be considered to be a light source.\n(6) Light sources that allow the end-user to control, manually or automatically, directly or remotely—\n(a) the luminous intensity;\n(b) colour;\n(c) correlated colour temperature;\n(d) spectrum; or\n(e) beam angle,\nof the emitted light, must be tested using the reference control settings.",
