IEC60335-2-17 Figure BB.1 to BB.3 Equipment for the mechanical strength test of blankets

1. Introduction

The blankets mechanical strength test apparatus is designed according to IEC60335-2-17 clause 21.102 and Annex BB.1 to BB.3. It’s used for mechanical strength test by simulating the actual use of the blanket. Pulling the blanket by the driving bar, the driving sprocket operating at a speed of 33r/min. Rotated the blanket 1000 times with an end attached to the driving bar and then turned through 90° and rotated another 1000 times.
