14、otechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. T
15、o this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC Nati
16、onal Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (
17、ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation
18、 from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot b
19、e held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. A
20、ny divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access
21、to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individ
22、ual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, th
23、is IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of th
24、is IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. A PAS is a technical specification not fulfilling the requirements for a standard, but made available to the public. IEC/PAS 62816-2 has been processed by subcommi
25、ttee 34A: Lamps, of IEC technical committee 34: Lamps and related equipment. The text of this PAS is based on the following document: This PAS was approved for publication by the P-members of the committee concerned as indicated in the following document Draft PAS Report on voting 34A/1598/PAS 34A/1
26、617/RVD Following publication of this PAS, which is a pre-standard publication, the technical committee or subcommittee concerned may transform it into an International Standard. 4 PAS 62816-2 IEC:2013(E) This PAS shall remain valid for an initial maximum period of 3 years starting from the publicat
27、ion date. The validity may be extended for a single period up to a maximum of 3 years, at the end of which it shall be published as another type of normative document, or shall be withdrawn.

28、s part of IEC/PAS 62816 specifies the performance requirements for tubular type external electrode fluorescent lamps for backlight unit purposes used in flat panel displays such as TVs and monitors, etc., hereafter called “lamps”.

A lamp shall be so designed that its performance is reliable in normal and
45、accepted use. In general, this can be achieved by satisfying the following requirements. It can be expected that lamps which conform to this PAS will start and operate satisfactorily at voltages of 94 % and 106 % of the rated supply voltage and at an ambient air temperature of between 23 C and 27 C.
46、 8 PAS 62816-2 IEC:2013(E) The requirements and tolerances permitted by this PAS are based on testing of a type test sample submitted by the manufacturer for that purpose. In principle, this type of test sample should consist of units having characteristics typical of the manufacturers production an
47、d be as close to the production centre-point values as possible. For guidance on sampling plans and procedures, see IEC 60410. 5.2 Tests 5.2.1 General All tests shall be performed in accordance with Annex C, according to the order arranged by each group in Table 1. In the case of sequential tests wi
48、th the same sample, the former test result shall not influence the following test result, and the destructive test shall be performed last of all. NOTE However, the destructive test can be performed with another sample. 5.2.2 Construction Values of measurement of a lamp diameter, length, and lead wi
49、re length shall be in accordance with Annex A. The surface of the lamp and external electrode shall be free from bubbles, flaws and stains that would be an inconvenience during use. 5.2.3 Starting characteristic 5.2.3.1 General starting test Immediately prior to the general starting test, the lamps shall be kept inoperative and in an ambient temperature of between 23 C and 27 C and a relative humidity of 65 % maximum for a period of at least 24 h. When tested under windless conditions, the
