IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization composed of electrotechnical committees (IEC national focal committees) from all over the world. The purpose of IEC is to promote international cooperation on standard issues in the electrical and electronic fields. To this end, among other activities, IEC also publishes international standards. The formulation of each standard is entrusted to each sub-technical committee; any IEC national focal committee that is interested in the subject under discussion can participate in the formulation of the standard. All international, governmental and non-governmental organizations that have liaison relations with IEC can also participate in the formulation of standards. There is an agreement and close cooperation between IEC and the International Organization for Standardization (ISO). 2) IEC's formal resolutions and agreements on technical issues are formulated by technical committees, and all national committees with special interests are represented. Therefore, these resolutions and agreements express the international consensus on this issue to the greatest extent possible. 3) Recommended standards, reports or guidelines published for international use are, in a sense, adopted by national committees. 4) In order to promote international unification, IEC national focal committees should ensure that IEC international standards are adopted to the greatest extent possible in their national or regional standards. Any differences between IEC standards and national or regional standards should be clearly stated in the latter. 5) The IEC committee does not provide any marking method to indicate recognition and is not responsible for any equipment that claims to comply with a standard of the IEC committee.
IEC1199 international standards were formulated by 34A: Lighting Technical Committee, and IEC34 Technical Committee is: Lights and Related Annexes. This standard is drafted based on the following documents

Safety requirements for single-capped fluorescent lamps
Single-capped fluorescent lamps-Safety specifications 1 General requirements
1.1 Scope
This standard specifies the safety requirements for single-capped fluorescent lamps for general lighting use with the following lamp caps: GB16843-1997
idt IEC 1199:1993
2G7, 2GX7, GR8.G10q, GR10q, GX10q, GY10q, 2G11, G23.GX23.G24, GX32 and 2G13. This standard specifies the method for determining whether the manufacturer's products meet the requirements of this standard based on the evaluation of all products and the manufacturer's test records of the finished lamps. This method can also be used for product certification. This standard also specifies the details of the inspection procedure for evaluating batch products. The various requirements for batch inspection include the content of evaluating all aspects of batch products containing unsafe lamps. If some safety requirements cannot be verified through batch testing, and there is no ready-made basis for quality from the manufacturer, the results of batch inspection cannot be used for product certification, nor can batch products be accepted. At this time, when inspecting batch products, the inspection agency can only determine that the batch products have only a certain degree of safety.
Note: The qualification conditions of this standard only involve safety indicators, and do not consider the performance indicators of single-capped fluorescent lamps for general lighting, such as luminous flux, color, starting and working characteristics.
For the above data, users should refer to the first edition of IEC901 "Safety and Performance Requirements for Single-Capped Fluorescent Lamps". The next edition of this standard will only contain performance requirements. 1.2 References
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards.

Tests for evaluating the structure and assembly of lamp holders
When a lamp is inserted into or removed from a lampholder, it is possible that a part of the lamp holder may be pulled apart. Therefore, the following type test shall be carried out. For the qualified conditions, see Appendix D1.
Apply a tensile force of 80N to each part of the lamp holder that is considered likely to be pulled apart. The tensile force shall be maintained for 1 min. Do not pull violently. After the test, the lamp holder shall be safe and there shall be no opening of any joints, or the test finger shown in IEC529 can be inserted into and contact the gap of the strap parts.
The method of applying tensile force to each part of the lamp holder shall not weaken its structure. If necessary, the manufacturing and inspection agencies may prepare special specimens through negotiation.
For lamps equipped with G10q caps, the following additional routine tests shall be carried out. The cap shall be easily rotated about the plane through the glass tube within a nominal angle α and shall be rotated at least ±5°. The conductors shall not be short-circuited when the cap is rotated to the maximum angle. The test finger shall not be able to penetrate and touch live parts when the cap is turned to an unfavorable position. A1.2 Lamps after heating test
For lamps heated in a heating cabinet for 2000h ± 50h at the temperature specified in Appendix G, all the tests and requirements specified in A1.1 shall be applied when carrying out type tests. For qualified conditions, see Appendix D1. A22 G7, 2GX7, GX10q, GY10q, 2G11.2G13, G23, GX23, G24 and GX32 caps A2.1 Unused lamps
The following routine tests shall be applied to check their qualification. Neither the lamp tube nor the lamp holder shall be loose when a 40N axial tension or 3N·m bending moment is applied. When applying the bending moment, the glass tube should be evenly held at the part closest to the lamp holder. The fulcrum is located on the reference plane of the lamp holder (the plane intersecting with the lamp holder). The tension and bending moment shall not be applied suddenly, but shall be gradually increased from zero to the specified value.
A2.2 Lamps after heating test
Lamps heated in a heating box for 2000h±50h at the temperature specified in Appendix G shall be subjected to tension and bending moment tests (tension and bending moment values are under study). For qualified conditions, see Appendix D1. Appendix B
