8.5.5.2 Test method
For the protection against the effects of a high pressure lamp failure, the following test is performed as follows:
– lamp assemblies considered MS3 parts during field replacement are tested separate from the equipment;
– lamp assemblies only considered MS3 parts during operation, may be tested separately,or as normally installed in the equipment, or both.
An explosion of the lamp is stimulated by mechanical impact, electronic pulse generator or similar method. The lamp shall operate for at least 5 min to obtain operational temperature and pressure. To evaluate the rupture results for potential debris area and particle size, the equipment or lamp assembly is placed on a horizontal surface, and a dark sticky mat (or another adequate method) of adequate size to capture the particles is placed near the exhaust vent of the equipment. The equipment opening shall be oriented to maximize potential for particles to be expelled from the product horizontally across the dark sticky mat.
After the rupture, the glass particles generated are measured using a magnified glass piece with a 0,1 mm resolution. The test shall be conducted to simulate the worst case operating position specified in the instructions.
