Now, in the next section, we will learn about test requirements and product scope of the IS 15111 Part 1.
Scope of IS 15111 Part 1
IS 15111 Part 1 provides information with respect to safety and interchangeable requirements including the test methods and conditions, required to show compliance of tubular fluorescent and other gas discharge lamps with integrated means for controlling starting and stable operation (self ballasted lamps), intended for domestic and similar general lighting purposes having -
- A rated wattage upto and including 26W
- A rated wattage upto and including 250W
- Edison screw E14 and E27 or bayonet cap B15d and B22d
Test Requirements and Parameters Tested
1. Cap temperature rise
Under this, the rise in temperature of surface (above ambient) of a standard test lamp fitted to a lamp, would be measured as per IS 15111 Part 1 as follows -
- Live Parts - A conductive part which might result in electric shock in a normal use.
- Type Test - A test or series of tests conducted on the type test sample with the motive to check the compliance of the design of a given product in accordance with the requirements provided in the specification.
- Type Test Sample - A type test sample is a sample submitted by the manufacturer or a concerned vendor to conduct a type test.
- Acceptance Test - A test to be conducted on a lot with the purpose to conduct an acceptance test.
- Inspection Test Quantity (ITQ) - ITQ refers to the number of samples selected to determine the acceptability of a batch as to a marking, interchangeability, protection against electric shocks, insulation resistance, electric strength, and mechanical strength.
- Rated Luminous Flux - It is a fluxed mark on the lamp or declared by the manufacturer or concerned vendor.
2. Fault conditions
The lamp must not reduce the safety when operated under fault conditions, which could occur during intended use. Only one component is subjected to fault conditions at a time as follows -
- In case of a switch start circuit, the starter is short circuited.
- Short circuit across capacitors.
- Due to a broken cathode circuit, the lamp would not start.
- The lamp does not work, even though the cathode circuits are intact.
- Opening or bridging other points in a circuit, in a way that fault conditions might impair safety.
3. Insulation resistance and electric strength after humidity treatment
The insulation resistance and electric strength after humidity must be appropriate between current carrying parts of the lamps and accessible parts of the lamp. Let’s understand about both in details -
The lamp must be conditioned for 48 hours in a cabinet possessing air with relative humidity between 91% and 95%, while the air temperature needs to be marinated within 1-degree celsius of any convenient value between 20-degree celsius and 30-degree celsius.
Moreover, insulation resistance must be measured in the humidity cabinet with the DC voltage of approx 500V. After one minute of application of voltage, the insulation resistance between current carrying parts and accessible parts of the lamps must not be below 4 M ohm.
Instant after conducting insulation resistance test, the same parts must withstand the a voltage test for a minute as follows -
Screw caps - between accessible parts and screw cap, as follows -
Type HV ( 220V to 250V ) : 4 000 V r.m.s.
TypeBV( lOOV to 120V):2U+ 1 OOOV
Value U = rated voltage.
It is to be noted that during the test cycle, the shell of the cap can be short-circuited. Initially, not more than half of the provided voltage is applied, then would be gradually increased to full value. And no flashover or breakdown must occur during the test and measurement must be taken in the humidity cabinet.
4. Interchangeability test
The interchangeability test would be conducted in accordance with the relevant standards. Moreover, the compliance of combination of cap and gulb will be checked by the use of gauges with the purpose to check the dimensions controlling the interchangeability as per relevant standard.
**5. Marking **
The lamps must be appropriately marked with the mandatory marking as follows -
- Marking of origin
- Rated voltage or the range of voltage, marked, “V” or “Volts”
- Rated wattage, marked, “W” or “Watts”
- Rated frequency, marked, “Hz”
- Rated luminous flux
- Rated color temperature
- Country of manufacture
Including that, below mentioned information needs to be provided on the lamp or packaging of lamp -
- Lamp current
- If restricted, burning position
- The attention must be drawn to the fact that increased weight might reduce the mechanical stability of particular luminaries, in case of lamps with weight significantly higher than that of lamps for which they are replaced
- Special conditions or restrictions which would be observed for lamp operation
The compliance must be checked as follows -
- Availability and legibility of marking required through visual inspection.
- The durability of marking will be checked by trying to remove through a rubber lightly for 15 seconds with a piece of soaked cloth after drying for 15 seconds with a piece of cloth soaked in hexane.
6. Protection against electric shocks
The self-ballasted lamps must be constructed without any additional enclosure in the form of luminaries and internal metal parts of lamp caps must be accessible when the lamp is installed in the lamp holder.
However, the lamps with Edison screw caps must be designed to avoid requirements of accessibility, which can be checked through the aid of gauge as provided in the relevant standard.
Also, the lamps with B22 caps are subjected to the same requirements like normal incandescent lamps with caps. And the external metal parts excluding the current carrying metal parts of cap must not be or become live and for testing, the movable conductive material must be in most onerous position without any use of tool.
7. Resistance to flame and ignition
The parts of insulation material retaining live parts in position and external parts of insulation material providing protection against electric shocks are subjected to glow wire test as follows -
- The test specimen is a complete lamp and it could be necessary to take away the parts of the lamp to conduct the test.
- The test specimen would be mounted on the carriage and pressed against the glow-wire tip with the force of IN, preferably 15mm or above.
- If the specimen is too small to be tested in the above mentioned position, the same test will be conducted on the same, yet separate specimen of same material with 30mm square and thickness equal to the smallest thickness of specimen.
- The temperature of the tip of the glow wire is 650-degree celsius, after 30 seconds the specimen will be withdrawn from contact with the glow wire tip.
- The glow wire temperature and heating current must remain constant for a minute before commencing the test.
- Any flame or glowing of specimen must be extinguished within 30 seconds of withdrawing the glow-wire and any flaming drop must not ignite a piece of tissue, which is spread horizontally 200 +/- 5mm below specimen.
8. Resistance to heat
The self-ballasted lamps must be ideally resistant to the heat, while the external parts of insulating materials must provide protection against electric shock and parts of insulating materials retain live parts in a way which must resist heat.
Moreover, the compliance will be checked through a ball-pressure test as provided in the specification.
Further, the test is made in a heating cabinet with the temperature of 25 +/- 5-degree celsius in the excess of temperature as provided in the relevant standard and with a minimum of 125-degree celsius for the parts retaining live in position and 80-degree celsius for other parts. While the surface part to be tested in horizontal position and steel ball of 5mm diameter pressed against the surface with a force of 20N.
With that, the test load and means will be placed within the heating cabinet for adequate time in order to ensure that stabilized testing temperature is achieved prior to commencement of test. Then the part which needs to be tested will be placed in the heating cabinet for the duration of 10 minutes prior to the application of test load.
Additionally, if the surface under test bends, the part where ball presses are supported, and, if the test can not be conducted on the test specimen, then an adequate part might be cut from it and it must be at least 2.5mm thick.
After an hour a ball is removed from the specimen, which will be immersed in cold water for 10 seconds to cool it at room temperature and the diameter of immersion must not exceed over 2 mm.
