Are explosion proof lights waterproof and test conditions for IP66 IP67 IP68 waterproof rating

Are explosion proof lights IP66 waterproof?

Explosion-proof lamps are not necessarily waterproof.

Explosion-proof lamps are used in hazardous places where combustible gases and dusts exist, and can prevent the arc, sparks and high temperature that may be generated inside the lamp from igniting the combustible gases and dusts in the surrounding environment, so as to achieve the explosion-proof requirements for lamps and lanterns. Also known as explosion-proof lamps, explosion-proof lighting. Specific reference GB3836, IEC60079.

In general, LED explosion-proof lamps have the role of waterproof, but there are differences in waterproof grade, in the purchase and use of LED explosion-proof lamps should also identify the waterproof grade is in line with the actual need.

Explosion proof lamp waterproof grade test conditions

IP66 waterproof grade test conditions

Spray pressure and water flow: the use of water spray nozzle inner diameter of 12.5mm equipment, water pressure between 100kPa to 150kPa, water flow rate of 100L/min (6000L/h). Spray distance and time: the water spray distance is generally 2.5 meters to 3 meters, the water spray time of at least 3 minutes, and need to be sprayed from different angles to the equipment. Test environment: the temperature, humidity, air pressure and other parameters of the test environment can be controlled, no dust, no corrosive gases, no direct sunlight.

Test conditions for IP67 waterproof rating

The test conditions for IP68 waterproof rating for prolonged and continuous immersion in water, if there is no corresponding product standard, should be determined by consultation between the user and the manufacturer, and are more severe than the test conditions for IP67 waterproof rating for short-term immersion in water. Therefore, in order to facilitate the understanding of the test conditions of IP68, you need to first understand the IP67 short-time immersion test, as follows.

The sample should be completely submerged in water according to the specified installation status, and: 1. height less than 850 mm of the lowest point of the sample shell, should be low pressure water surface 1 m, the test time of 30 min; 2. height of not less than 850 mm of the sample shell of the highest point, should be lower than the surface of the water 0.15 m, the test time of 30 min; 3. temperature difference between the water temperature and the specimen is not greater than 5 K, the specimen needs to be electrically charged and/or in the working When the specimen needs to be electrified and (or) in the working condition for the test, the product standard can be separately specified for this temperature difference.

IP68 waterproof grade test conditions

After understanding the IP67 short-term immersion test, you can know the IP68 continuous immersion test of the immersion depth and immersion time of the critical requirements for: the test time should be greater than 30 min; test the depth of water for the height of less than 850 mm equipment should be greater than 1 m, for the height of the equipment is not less than 850 mm, the test depth of water should be higher than the top of the equipment 0.15 m or more.

Different waterproof grade explosion proof lamps in different environments application scenarios:

IP65/IP66: Suitable for coal mine underground and dusty industrial places, which can completely prevent dust from entering and splashing water from intruding, ensuring that the lamps work stably in dusty and splashing water environments.

IP67: Suitable for offshore drilling platforms, ships and other environments that may come into contact with splashing or immersion water, able to be immersed in water at a specified pressure for a short period of time, to ensure that the luminaire works reliably in wet and immersed environments.

IP68: Suitable for underwater work, marine exploration and other environments that are submerged in water for a long period of time, able to maintain normal operation under high pressure and prolonged immersion in water, ensuring the stability and reliability of the equipment in the underwater environment.

Selection of suitable waterproof grade explosion-proof lamps is important to ensure the normal operation of the equipment, extend the service life and reduce maintenance costs. In practical applications, should be based on the specific environment and demand for a reasonable choice of the appropriate IP protection level to ensure the safety and reliability of explosion-proof lights in a variety of harsh environments.

Explosion proof lights IP66 FAQ:

1. IP66 explosion-proof lamps can be used in which areas?

Petrochemical plants, pharmaceutical workshops, grain silos, gas stations, offshore platforms and other outdoor/wet environments where there is a risk of explosion and need to be dustproof and waterproof.

2. Can IP66 explosion-proof lamp be completely immersed in water?

No, it can’t! Only anti-spray water, not water immersion. IP67/IP68 should be selected for submersible lighting.

3. IP66 explosion-proof lamps need regular testing?

Absolutely! Regular inspections are a key part of ensuring explosion-proof safety.

4. How to clean and maintain IP66 explosion-proof lamps?

Disconnect operation: Make sure the power is off and the environment is safe (no flammable gases).

Cleaning: Wipe the shell and lampshade with a damp cloth + neutral detergent, high-pressure water gun is strictly prohibited direct spray sealing parts!

Inspection: Whether the seal ring is aging and deformed (timely replacement). Lampshade has no cracks / yellowing. Whether the fasteners are loose rust.

Professional maintenance: internal overhaul must be operated by specialized personnel, and restore the explosion-proof sealing structure when installing back.

Records: Keep a maintenance log, regular comprehensive testing.
