Product should have anormal performance after battery bending test：F=200 N， hold time 60s. Normal operation. Max 0.2mm permanent deflection after test. Nokia Bending Jig making procedure 1.1Material： Aluminium EN6082-T6 (The marking T6 behind the material number isa grade of tempering. It means heat-treated and then artificially aged.) 2.Milled with NC machine tool. (Surface milled to be as smooth as possible) 3.Manually finished. 4. Surface roughness (2.0 Ra) made with glass shot blasting. 5. B[lack anodizing. (Short time in the alkaline soaker to remove oxide layer. Nomajor influence to the surface roughness). The reference for the bending jig material can be found from JIS H4000. ChemicalComposition of material 6082 are mentioned below. The composition is (unit： %)： Si 0.70-1.3.

Thenthe bigger one ofthese two(extensions)arechosen for the anglecalculation.(Sameprocedure is donefor anticlockwisedirection also(b1/b2)). Battery positioning in twisting test Top of the battery (hotmelt) placed~1.8 mm inside the twisting jig. The width between the hooks (thefeatures gripping the battery from thenotches) is 30.30mm. ·BBottom of the battery placed ~4.9mminside the twisting jig. ·Both clockwise and anticlockwisedirections have to be tested. · First twisting direction is clockwisefrom the front of the battery pack. ·The max value is taken from 30 secperiods， the2 second periods are nottaken into account.
