Impact and Fall Protection Ratings of SimplePack and SimpleIndustry

We performed device tests according to guidelines described in three international standards:

  • IEC 62262:2002
  • IEC 60068-2-31
  • MIL-STD-810
Info

We have adjusted a few aspects of them without any impact on integrity of test results and will state those changes in each section of this article.

IEC 62262:2002

You can find what this standard is about HERE!

How we tested this:

As standard, a 1.000g steel ball with a 50mm diameter is used (5.000g for IK10). We have used a 900g 40mm-diameter steel ball and adjusted the height of fall from the case in order to get the same impact energy in joules (J). Our version is slightly harder to pass.

SimplePack

IK rating Standard requirement Fall height Actual impact force Result
IK07 2 Joules 300 mm 2.65 Joules Passed
IK07 2 Joules 400 mm 3.53 Joules Passed
IK07 2 Joules 500 mm 4.41 Joules Passed
IK08 5 Joules 600 mm 5.29 Joules Passed
IK09 10 Joules 1200 mm 10.58 Joules Passed
IK10 20 Joules 2300 mm 20.29 Joules Impact on case edge*

*Enclosure impacted but the device is still working fine (with the larger ball, lower height and straight impact, the official IK10 should be passed easily)

SimpleIndustry

IK rating Standard requirement Fall height Actual impact force Result
IK09 10 Joules 1200 mm 10.58 Joules Passed
IK10 20 Joules 2300 mm 20.29 Joules Passed

IEC 60068-2-31

How we tested this:

We have only performed the free fall part of this International Standard. Both the SimplePack and the SimpleIndustry were tested in the following manner:

  • Free fall from 1) 750mm and 2) 1.000mm
  • 2 repetitions each
  • Landing on a steel plate on hardwood

SimplePack

Height Test result
750mm Passed
1.000mm Passed

SimpleIndustry

Height Test result
750mm Passed
1.000mm Passed
Info

Test result: No visible damage and device is working fine.

MIL-STD-810

You can find what this standard is about HERE!

How we tested this:

We have selected the “Logistic transit drop test” subtest of this standard. These are the conditions:

  • Plywood/steel landing plate - we used a hard plastic pallet to simulate plywood
  • Height of fall of 48 inches (1210 mm)
  • 26 repetitions of fall on all edges

SimplePack

Passed without any visible or internal damage. The device is very lightweight and has no problem being tossed around.

SimpleIndustry

Doesn’t pass as the device is very heavy and the force on the internal parts of the device is too strong to handle. The battery holders cannot hold the batteries in repeated falls. This could be solved by filling the device with gel/epoxy in order to spread the impact force.
