2.3.3Dimensions
lf tungsten halogen lamps use standardized caps/bases they shall be in accordance with therequirements of iEC 60061-1.
Compliance is checked on finished lamps by using the gauges of lEC 60061-3.
Non standardized caps/bases shall be in accordance with the manufacturer’s specification.Compliance is checked by inspection.
2.4 Maximum uv radiation of self-shielded lamps
The specific effective radiant Uv power of self-shielded tungsten halogen lamps shall notexceed:
2 mW/klm or,
-for reflector lamps 2 mw/(m2·klx).
Compliance is checked by measurement of the spectral power distribution.2.5Gas pressure of low-pressure self-shielded extra low voltage lamps
During operation, the gas pressure of single-capped low-pressure self-shielded ELV tungstenhalogen lamps shall be limited. This shall be achieved by restricting:
a)the cold fill pressure to less than 1 × 105 Pa (1 bar), and
b)the lamp volume to 1 cm3 maximum,and
c)the rated wattage to 100 w maximum.
Compliance is checked by inspection and by means of the test specified in Annex B.
2.6Safety at end of life of self-shielded lamps with rated voltages from range B or cWhen tested under the specified conditions, lamp failure shall not be accompanied bybreakage of the bulb nor its ejection from the cap.
For bayonet capped lamps, it is also required that there shall not be an internal short-circuit tothe cap shell after the test.
The test conditions are:
an induced-failure test in accordance with Annex F, or- an operation-to-failure test.
The operation-to-failure test shall be carried out under the conditions specified for the life testprocedure in Annex A of lEC 60357.The test rack circuit characteristics shall be in line withTable E.1 of IEC 60432-1.The test is continued until end of life.
NOTE 1 In the event of dispute the reference test method is the induced failure test.
NOTE 2 Some lamp designs are not suitable for testing with the induced failure test because a breakdown cannotreliably be achieved.Such lamps,provided they are of voltage range B or C, will be submitted to an operation-to-failure test as described above.”
2.7 Information for luminaire design
Refer to Annex C.
3 Assessment
3.1 General
This clause specifies the method a manufacturer should use to show that his product conforms to this standard on the basis of whole production assessment, in association with his test records on finished products. This method can also be applied for certification purposes. Subclause 3.2 gives details of assessment by means of the manufacturer’s records. Details of a batch test procedure which can be used to make limited assessment of batches are given in 3.3. Requirements for batch testing are included in order to enable the assessment of batches presumed to contain unsafe lamps. As some safety requirements cannot be checked by batch testing, and as there may be no previous knowledge of the manufacturer’s quality, batch testing cannot be used for certification purposes nor in any way for an approval of the batch. Where a batch is found to be acceptable, a testing agency may only conclude that there is no reason to reject the batch on safety grounds.
3.2 Whole production assessment by means of manufacturer’s records The manufacturer shall show evidence that his products comply with the particular requirements of 3.2.1 . To this end, the manufacturer shall make available all the results of his product testing pertinent to the requirements of this standard. The test results may be drawn from working records and, as such, may not be immediately available in collated form. The assessment shall be based in general on individual factories, each meeting the acceptance criteria of 3.2.1 .
However, a number of factories may be grouped together, providing they are under the same quality management. For certification purposes, one certificate may be issued to cover a nominated group of factories, but the certification authority shall have the right to visit each plant to examine the local relevant records and quality control procedures. For certification purposes, the manufacturer shall declare a list of marks of origin and corresponding lamp families, groups and/or types which are within the scope of this standard and manufactured in a nominated group of factories. The certificate shall be taken to include all lamps so listed made by the manufacturer. Notification of additions or deletions may be made at any time. In presenting the test results, the manufacturer may combine the results of different lamp families, groups and/or types according to column 4 of Table 1 .
The whole production assessment requires that the quality control procedures of a manufacturer shall satisfy recognized quality system requirements for final inspection. Within the framework of a quality assurance system based also on in-process inspection and testing the manufacturer may show compliance with some of the requirements of this standard by means of in-process inspection instead of finished product testing.
