This standard specifies the requirements for heat test source lamps (I1.T,S.) for heating tests described in the GB 7000 series of standards. These heating tests are mainly used to verify the effects of heat conduction and convection on the lamp holder. For the source and characteristics of this standard, see Appendix A. In cases where it is not appropriate to use a heat test source lamp (HTS), an alternative heat test source lamp (A,HTS,) may be used. For how to select and prepare such lamps, see Appendix B of GB7000.1-2002. Appendix A also gives certain requirements for radiation test sources (RTS). 2 Normative referencesbZxz.net

Heat test source (HTS)) heat test sourceH.T,S.) A lamp whose lamp cap temperature rise (At,) is equal to the maximum allowable lamp cap overflow rise (△tmx) of a specific type of lamp shown in the corresponding parameter table in the corresponding standard of GB 14196.
Alternative heat test source (A, HTS) Alternative heat lest source (AHTS) Commercial lamps whose lamp cap temperature rise (△t,) is below 5K and can reach the maximum allowable lamp cap temperature rise (t..max) of a specific type of lamp as shown in the corresponding parameter table in the corresponding standard of GB14195: Regarding 100V lamps, it is still under study.

The lamp cap temperature rise should be measured at an ambient temperature of 25℃ and in accordance with the provisions of QB/T2512. GB/T19657—2005/IEC 60634:19935 Requirements for heat test source lamps for heating tests of incandescent lamps The temperature rise of the lamp cap shall be equal to the maximum allowable lamp cap temperature rise of the specific type of lamp shown in the corresponding parameter table in the corresponding standard of GB14196 5.1

The corresponding test voltage shall be marked on the lamp or specified in the parameter table of the heat test source lamp.

Note: The above tolerance range graph takes into account the following situation: that is, in the production process of the heat test source lamp, the span of the lamp cap temperature rise is much larger than that of the power. Experience shows that when measuring the temperature at the shunt point of the lamp, the influence of the power tolerance on the measured temperature is 1.5 times greater than the influence of the lamp cap temperature rise tolerance on the measured temperature, which allows the lamp cap temperature rise tolerance to be widened, so that more lamps can be selected as heat test source lamps. In the area surrounded by A, B, C, D, E and F, the tolerance of the lamp cap temperature rise can be larger than the span of the power tolerance.

Origin and development of heat test source lamps
Luminaires for incandescent lamps must meet various safety requirements, two of the most important of which are that the lamps must prevent users from accidentally touching live parts and from being injured by lamp fires. This requires strict limits on the temperature generated during the use of the lamps (see GB7000.1). In order to prevent premature aging, melting or shrinkage of parts providing electric shock protection or fixed current-carrying parts, the temperature of the materials used in the lamp should not exceed the temperature limit for which it is applicable. In order to verify this requirement, the lamp must be subjected to a heating test during routine testing. For this test, two types of test lamps are used: a heat test source lamp, which is mainly used to verify the conduction heat effect of the lamp holder in the lamp holder and the circuit; and an auxiliary test source lamp, which is used to verify the effect of thermal radiation energy on other parts of the lamp. For this purpose, commercial lamps with corresponding glass shell coatings and shapes, sizes, lamp holders and rated voltages should be used. The lamp glass must be transparent, without unnecessary markings, coatings, etc. For (100V~130V) low medical general lighting lamps, since some types of lamps use axial filaments and other types of lamps use transverse filaments, which can produce different temperatures in the lamp, the shape of the filament of this lamp must be taken into account. Lamps with reflectors or reflective bowls can also be used as radiation test source lamps, but lamps with transparent non-reflective parts cannot be used as radiation test source lamps (even if such lamps have been commercialized).
Radiation test source lamps do not need to be equipped with adjustable mixed rise △, A. 2 Basic provisions for thermal test source systems
The measurement of thermal test sources and lamp-related temperatures is based on the following basic provisions: a) Thermal test source lamps are basically determined according to rated power, size, lamp cap type and lamp cap temperature rise; b) The measurement method of lamp cap temperature rise △t, (set simplified method) is given in QB/T2512 c) The maximum average lamp cap rise of white baking lamps with different rated powers is given in the corresponding standard of GB14196: d) For these rated powers, the thermal test source lamp is used to simulate the lamp with the maximum allowable average lamp cap temperature rise of the corresponding rated power; e) The maximum rated power of the lamp used should be marked on the lamp. A.3 General Notes
1) The basis of the "gentleman's agreement" of (EE/FC 1963) is that the current practical practices for lamps should not be changed by new requirements, and this basis is still valid.
2) The agreement of CEF/1FC 1963 only makes detailed provisions for pear-shaped lamps with F27 lamp caps and rated powers of 60W, 100W, 150W, 200W and 300W. Secondly, the parameters of lamps with B22 lamp caps and rated powers of 60W, 100W and 150W are derived.
3) Lamps not mentioned in 2) above must comply with the following conditions: a) For lamps with the same glass bulb shape and power but different lamp cap models, since they are used in different lamps, the same temperature rise requirements do not have to be adopted.
GB/T 19657—2005/1EC 60634:1993b) If lamps with the same power and lamp cap but different glass bulb shapes are used in the same luminaire, they should have the same temperature rise △ limit values. For example, this is the case with pear-shaped lamps and mushroom-shaped lamps, but not necessarily with tube-shaped, candle-shaped or dome-shaped lamps.
Lamps with the same lamp cap and glass bulb shape but different rated power can have different temperature rise △t limits because their critical state in the luminaire test is the state when tested with a thermal test source with the maximum rated power. Therefore, under conditions that do not endanger safety, lamps with lower rated power can have a suitably higher temperature rise △t. For detailed limit value data, please refer to Appendix B GB/T19657--2002 of GB7000.1-2002. 5/IEC60634,1993 Test period:
