In outdoor exploration, construction sites, rescue and other special scenes, RuggedTablet computer has become an indispensable productivity tool, but many users in the purchase of a strange phenomenon: obviously IP protection level from IP65 to IP68 a full range, but only the lack of IP66. today, and we will be in-depth analysis of the industry cold knowledge.
First, IP protection level overview
IP (IngressProtection) code developed by the International Electrotechnical Commission (IEC), contains two key indicators:
The first digit: dustproof grade (0-6)
2nd digit: waterproof rating (0-9K)
Focus on common combinations of RuggedTablet devices:
IP6X: Highest level of dust protection, complete protection against dust intrusion
Waterproof rating differences:
IP65: Resistant to 12.5L/minute low-pressure water jets
IP66: Resistant to high pressure jets of 100L/minute
IP67: withstands short-term 1 metre water depth immersion (30 minutes)
IP68: Continuous underwater operation (depth time defined by manufacturer)
Second, why is IP66 so rare?
1. Mismatch between testing cost and market demand
IP66 certification requires special high-pressure water gun test equipment, but the actual application, the need to withstand sustained high-pressure water scene is very limited, so the market is more inclined to research and development of a wider range of IP67/IP68 products.
2. Protective ability ‘high but not low’
Compared with IP65 (daily waterproofing) and IP67 (emergency waterproofing), IP66 can not reach the depth of waterproofing standards, the cost of protection is higher than the general waterproofing needs, into the market positioning embarrassment.
3. Technical realisation of the specificity
To achieve IP66 need to add multiple drainage channels in the structural design, which is required with IP67/68 completely sealed programme there is a conflict of technical routes, it is difficult to get both.
Third, the industry RuggedTablet purchase guide
Catering / medical / retail → mainly anti-splash disinfectant, beverage splash IP65 level is sufficient.
Outdoor inspection/exploration/logistics and transport → the best choice of IP67 level of protection to cope with bad weather.
Underwater work / ship → IP68, specific also need to confirm the depth parameters of the product waterproof.
In the desert, mining and other scenes, you need to focus on dustproof performance, must reach IP6X level.
Fourth, the use of small Tips
Certification standards: check whether the authority to test
Seal life: the rubber ring needs to be replaced in about 2 years.
Loss of use: drops, extrusion will reduce the protective performance
Temperature effects: extreme temperatures may lead to seal failure.
Conclusion
RuggedTablet device selection, but also need to return to the real use of the scene, according to the actual working environment to choose the most suitable protection programme, shopping, may wish to take this guide to find a real match the needs of the productivity tools!
