Driver Bubble™ Shield material is approved by Millbrook Proving Ground for TfL compliance
As of 21st August 2020, the materials used to manufacture the Driver Bubble™ Shield standard has been approved and certified by Millbrook Proving Ground Ltd as part of the two-step process for full TfL compliance.
Millbrook Proving Ground Ltd suggested that additional testing (airbag deployment test) would be required in order to confirm compliance and that there is now adequate evidence to confirm the material will meet the TfL required standard.
As set out in the ECE 43.01 document, the Shield was subject to flexibility, impact 227g, fire resistance, light, and chemical resistance tests.
The Shield measured a 12mm vertical deviation. The required deviation limit is 50mm.
Impact 227g Passed
A ball was dropped onto the Shield from a height of 2m. There was no damage recorded at all.
Fire resistance Passed
The material used for the Shield is self-extinguishing so there was no burn rate calculation required.
The required transmission percentage required to pass the test was 70% and the Shield measured 89.67%.
Chemical resistance Passed
This test was conducted using non-abrasive soap, window cleaning solution, undiluted denatured alcohol, petrol and kerosene. For each chemical, the Shield did not see any softening, tackiness, crazing or loss of transparency.
In the coming days, the Shield will be subject to an airbag deployment test. Once the Shield has passed this test, the product will be fully approved and certified for use with TfL.
Keep your eyes open for the coming updates regarding the latter.
