Containment testing procedure for metal halide lamps
1
with quartz arc tubes
I.1 General
I.1.1 Purpose
This method of measurement applies to metal halide lamps with quartz arc tubes, that are
designed to contain all particles within the outer bulb should an arc tube rupture occur. These
lamps are permitted to be used in open luminaires. This is not a sufficient procedure for
evaluation of particle containment designs which employ protective coatings, e.g. a plastic
coating over the outer bulb.
I.1.2 Test description
The test consists of discharging a capacitor through an operating lamp to simulate an end-of-
life arc tube rupture. In the first part of the test, the median energy required to ensure rupture
of the arc tube is determined. In the second part of the test, arc tubes are forced to rupture at
the median energy, and the lamps are examined for damage to the outer bulb. The test differs
from real end-of-life situations in a number of ways, including: a) the lamps are new, b) a high
energy input into the arc tubes is required to make them rupture, leading to higher pressures
and greater energies than typical end-of-life ruptures, and c) the arc tube rupture mechanism
may not be the same as that for end-of-life lamps.
I.2 Experimental setup
I.2.1 Safety precautions
High voltages and high electrical energy levels are involved in this test, so extreme caution is
required. Fragments of hot lamp parts can be ejected if the outer bulb is damaged, so a
physical enclosure is required. Precautions should be taken to contain and clean up mercury
and other hazardous materials from the lamp in the event of penetration of the outer bulb.
I.2.2 Electrical circuit
The basic electrical circuit used for containment testing of metal halide lamps is shown in
Figure I.1. The main components include: (1) a power supply for operating the lamp, (2) a
ballast for limiting current to the lamp, (9) a d.c. power supply for charging the discharge
capacitor, (5) a discharge capacitor for storing energy for the containment test, (8) a charging
resistor for charging the discharge capacitor, (6) a discharge resistor for discharging the
capacitor after the test, (3) a VAW meter for measuring the lamp electrical operating
characteristics and (7) a V meter for measuring the capacitor voltage. Specific details for
2
designing and operating such a circuit can be found in SR91 .

Lamps, complying with the requirements of this annex are sometimes called “containment rated”, “open rated”
or “self-shielded”, the latter expression being preferred.

capacitor and the lamp shall be less than 1 m long and have a cross sectional area of 20 mm
or larger, except in the last section, where a smaller diameter may be used to facilitate
connection to a lampholder.
The capacitor discharge d.c. power supply shall be capable of charging the discharge
capacitor to any voltage up to 5 000 V. The value of the charging resistor can be adjusted so
that the power supply can charge the capacitor within a reasonable amount of time.
The discharge capacitor may be adjusted to a value of 10 µF to 50 µF (higher values may be
required for lamps of higher power) and shall be capable of handling 5 000 V.
The lamp power supply shall be capable of supplying the lamp with sufficient voltage and
current to operate the lamp at its rated operating power. A timing circuit may be inserted into
the circuit so that the capacitor is discharged at the point in the electrical phase when the
current is at its maximum.
The operational ballast may comprise a suitable linear reactor or commercial ballast, with a
suitable impedance as specified in the applicable lamp standard. It shall be capable of
withstanding short-term high voltage pulses of 5 000 V.
The switches shall be capable of withstanding short-term high voltage pulses of 5 000 V in
their open condition.
The discharge resistor shall have a rating of at least 1 000 Ω and 25 W.

I.2.3 Enclosure requirements
The enclosure for containment testing of metal halide lamps shall be constructed of materials
°
capable of withstanding the impact of hot particles (particles of up to 1,1 g at 1 200 C
travelling at 50 m/s). Suitable materials include sheet metal and impact-resistant, high-
temperature polymers. Metal enclosures shall be electrically grounded.
The enclosure shall be equipped with a suitable lamp holder for operating the lamp under test
in the base up position, or in the specified operating position of the lamp.
The dimensions of the enclosure are not critical, but they should be large enough to accept
the lamp under test and provide sufficient clearance at the sides and below the lamp.
I.3 Test procedures
I.3.1 Lamp selection and preparation
Lamps for this test shall be selected randomly from normal production or from pilot runs. The
lamp construction dimensions shall fall within the values of the lamp data sheets or the
manufacturer's specified values.
I.3.2 Determination of median rupture energy
In order to determine the median energy setting needed to rupture the arc tube within the
lamp, the following procedure shall be carried out, with reference to Figure I.1. Note that
these steps need to be carried out for each different lamp type.
1) Take care that the condition at the beginning is that the energy sources of charging and
lamp operation are not connected, lamp not inserted.
2) Select an initial energy value of at least 5 J by selecting the capacitor d.c. power supply
1/2
voltage according to U = (2 E / C) , where U is the capacitor voltage in volts (V), E is the
energy in joules (J), and C is the capacitor value in farads (F).
3) Open switches S1, S2, S3, S4; close switches S5, S6 and S7.
4) Insert a lamp into the test lampholder.
5) Turn on the lamp power supply and adjust to approximately the correct parameters to
operate the lamp. Use of this power supply may or may not require additional means of
starting.
6) Close the enclosure securely.
7) After 5 min, close switches S1 and S2, and open switch S6.
8) Determine the lamp electrical operating point by means of the VAW meter and adjust the
power supply as necessary to bring the lamp to its rated operating point.
9) Allow the lamp to operate for 20 min.
10) While waiting for the lamp to warm up, turn on the capacitor d.c. power supply, open
switch S5 and close switch S4 to begin charging the capacitor; monitor the capacitor
voltage by means of the voltmeter.
11) After the capacitor has reached its final charge and the lamp has operated at least
20 min, close switch S6 and open switches S1, S2 and S4.
12) Open switch S7 that triggers the closing of switch S3 to discharge the capacitor through
the lamp.
13) After the discharge, open switch S3 and close switch S5; turn off both power supplies.
14) If the arc tube ruptured at step 12, then repeat steps 3 to 13 until 8 lamps have been
tested. If at least 4 out of 8 arc tubes ruptured, then the energy and voltage values shall
be recorded, and these values shall be used for the rest of the test as described in I.3.3.
---------------------- Page: 7 ----------------------
– 6 – 62035 Amend. 2 IEC:2012
15) If the arc tube did not rupture in step 12, or if fewer than 4 out of 8 arc tubes ruptured in
the ensuing attempts, then the voltage at the discharge capacitor shall be increased to
obtain an energy increase of at least 5 J, and steps 3 to 14 shall be repeated. If the arc
tubes do not rupture reliably after increasing the voltage, an increase in capacitance may
be required.
I.3.3 Rupture test procedure
After the median energy required to ensure rupture of the arc tube has been determined
(see I.3.2), the following procedure shall be carried out to determine whether the lamps are
self-shielded.
Follow steps 3 to 13 in the I.3.2 (with the median energy value that ensures rupture of the arc
tube, as determined in that subclause). This procedure shall be followed until all the lamps of
the test group have been evaluated. The quantity of lamps in the test group shall be sufficient
to ensure at least 10 arc tubes rupture.
I.4 Self-shielded lamp design
I.4.1 Definition of damage to the outer bulb
Each of the lamps with ruptured arc tubes shall be examined for damage to the outer bulb.
For the purposes of this test, damage to the outer bulb constitutes any shattering, punctures,
or holes in the bulb wall. Scratches, cracks and chips on the bulb wall are allowed, as long as
all fragments are contained within the bulb, and the bulb remains intact.
I.4.2 Determination of self-shielded
If none of the lamps from I.3.3 shows any damage to the outer bulb (as defined in I.4.1), then
the lamp construction is self-shielded. If two or more of these lamps show damage to the
outer bulb (as defined in I.4.1), then the lamp construction is not self-shielded. If only one of
the lamps in the test group shows any damage to the outer bulb and this damage is limited to
a hole of less than 3 mm diameter in the bulb wall, then the test shall be repeated with a new
quantity of test lamps sufficient to ensure at least 10 arc tube ruptures. If none of the lamps in
this second test group shows damage to the outer bulb, then the construction is self-shielded.
If one or more of the lamps in this second test group shows any damage to the outer bulb,
then the construction is not self-shielded.

Containment testing procedure for metal halide
lamps with ceramic arc tubes
J.1 General
J.1.1 Purpose
This method of measurement applies to metal halide lamps with ceramic arc tubes that are
designed to contain all particles within the outer bulb should an arc tube rupture occur. These
lamps are permitted to be used in open luminaires. This is not a sufficient procedure for
evaluation of particle containment designs which employ protective coatings, e.g. a plastic
coating over the outer bulb.
J.1.2 Test description
The test consists of switching extra impedance in parallel with the operational ballast to
increase the energy in the arc tube and thereby simulate an end-of-life arc-tube rupture. In
the first part of the test, the median energy required to ensure rupture of the arc tube is
determined. In the second part of the test, arc tubes are forced to rupture at the median
energy, and the lamps are examined for damage to the outer bulb. The test differs from real
end-of-life situations in a number of ways, including: a) the lamps are new, b) a high energy
input into the arc tubes is required to make them rupture, leading to higher pressures and
greater energies than typical end-of-life ruptures, and c) the arc tube rupture mechanism may
not be the same as that for end-of-life lamps.
J.2 Experimental setup
J.2.1 Safety precautions
High electrical energy levels are involved in this test, so extreme caution is required.
Fragments of hot lamp parts can be ejected if the outer bulb is damaged, so a physical
enclosure is required. Precautions should be taken to contain and clean up mercury and other
hazardous materials from the lamp in the event of penetration of the outer bulb.
J.2.2 Electrical circuit
The basic electrical circuit used for containment testing of metal halide lamps is shown in
Figure J.1. The main components include: (1) a power supply for operating the lamp and
supplying extra energy to rupture the arc tube, (2) an operational ballast for operating the
lamp, (3) an extra impedance to switch in parallel with the operational ballast, and (5) volt-
and (4) ammeters for measuring the lamp electrical operating characteristics. The lamp power
supply shall be capable of supplying the lamp with sufficient voltage and current to operate
the lamp at its nominal operating power and at an increased energy level sufficient to rupture
the arc tube (typically 5 to 20 times the nominal operating power). The operational ballast may
comprise a suitable linear reactor or commercial ballast, with a suitable impedance as
specified in the applicable lamp standard. The extra impedance may comprise a variable
linear reactor, a reactor ballast, or a combination of reactor ballasts. The wiring and switches
shall be capable of handling at least 40 A.

J.3.2 Determination of median rupture energy
In order to determine the median energy setting needed to rupture the arc tube within the
lamp, the following procedure shall be carried out, with reference to Figure J.1. Note that
these steps need to be carried out for each different lamp type.
1) Take care that the condition at the beginning is that the energy sources of charging and
lamp operation are not connected, lamp not inserted.
2) Select an impedance for the extra impedance of about 20 % of that of the operational
4
ballast .
3) Open the switch and insert a lamp in the test lampholder.
4) Turn on the power supply and set the supply voltage to the rated voltage or greater for
the lamp under test. Up to 110 % of rated voltage and/or 120 % of rated power is
permitted.
5) Ignite the lamp and close the enclosure securely.
6) Operate the lamp for at least 10 min.
7) Close the switch to increase the energy in the arc tube.
8) Observe whether or not the arc tube ruptures within about 5 s.
9) Open the switch and turn off the power supply.
10) If the arc tube ruptured in step 8, then repeat steps 3) to 9) until 8 lamps have been
tested. If at least 4 out of 8 lamps ruptured, then the voltage and impedance values shall
be recorded, and these values shall be used for the second part of the test (see J.3.3).
11) a) If the arc tube stayed on but did not rupture within about 5 s, then the extra impedance
value shall be decreased, and steps 3 to 10 shall be repeated.
b) If the arc tube extinguished instead of rupturing, then the supply voltage shall be
increased and the impedance of the operational ballast may be increased to assure
operation of the lamp up to 120 % of rated power during the 10-min warm-up period.
Thereafter steps 3) to 10) shall be repeated.
J.3.3 Rupture test procedure
After the median energy required to ensure rupture of the arc tube has been determined
(see J.3.2), the following procedure shall be carried out to determine whether the lamps are
self-shielded.
Follow steps 3) to 9) in J.3.2 (with the median energy value that ensures rupture of the arc
tube, as determined in that subclause). This procedure shall be followed until all the lamps of
the test group have been evaluated. The quantity of lamps in the test group shall be sufficient
to ensure at least 10 arc tube ruptures.
J.4 Self-shielded lamp design
J.4.1 Definition of damage to the outer bulb
Each of the lamps with ruptured arc tubes shall be examined for damage to the outer bulb.
For the purposes of this test, damage to the outer bulb constitutes any shattering, punctures,
or holes in the bulb wall. Scratches, cracks and chips on the bulb wall are allowed, as long as
all fragments are contained within the bulb, and the bulb remains intact.

If none of the lamps from J.3.3 shows any damage to the outer bulb (as defined in J.4.1), then
the lamp construction is self-shielded. If two or more of these lamps show damage to the
outer bulb (as defined in J.4.1), then the lamp construction is not self-shielded. If only one of
the lamps in the test group shows any damage to the outer bulb and this damage is limited to
a hole of less than 3 mm diameter in the bulb wall, then the test shall be repeated with a new
quantity of test lamps sufficient to ensure at least 10 arc tube ruptures. If none of the lamps in
this second test group shows damage to the outer bulb, then the construction is self-shielded.
If one or more of the lamps in this second test group shows any damage to the outer bulb,
then the construction is not self-shielded.

aux halogénures métalliques à tubes à arc à quartz
I.1 Généralités
I.1.1 Objet
La présente méthode de mesure s'applique aux lampes aux halogénures métalliques à tubes
à arc à quartz, qui sont conçues pour retenir toutes les particules à l’intérieur de l’ampoule
extérieure en cas de rupture du tube à décharge à arc. L'utilisation de ces lampes est
autorisée dans les luminaires ouverts. Cette procédure n'est pas suffisante pour l'évaluation
des conceptions des rétentions de particules qui utilisent des revêtements de protection, par
exemple un revêtement plastique sur l'ampoule extérieure.
I.1.2 Description de l'essai
L'essai consiste à décharger un condensateur par l'intermédiaire d'une lampe en
fonctionnement pour simuler la rupture de fin de vie d'un tube à arc. Au cours de la première
partie de l'essai, on détermine la valeur médiane de l'énergie nécessaire pour entraîner la
rupture du tube à arc. Au cours de la deuxième partie de l'essai, on force la rupture des tubes
à arc à la valeur médiane de l'énergie et les lampes sont examinées pour rechercher les
dommages affectant l'ampoule extérieure. L'essai est différent des situations de fin de vie
réelles sur de nombreux points, y compris: a) les lampes sont neuves, b) une énergie élevée
est nécessaire en entrée des tubes à arc pour entraîner leur rupture, ce qui conduit à des
pressions plus élevée
