H.6.Investigation summary: three sample units were received for evaluation by our quality engineer team.Upon examination of the samples, no damages or molding defects were observed on any of the components.A device history record review (dhr) of lot 1612256p showed no anomalies during the production of the provided lot number that could have contributed to the reported defect.Break out force, sustaining force, and silicone content tests are performed during production.The provided samples were within specifications.As no defects could be found on the provided samples or from the production history a definite cause for the issue reported could not be determined.Final products are sampled from the manufacturing line and subjected to visual and functional inspections to prevent the distribution of defective product.Silicone content test and break out-sustaining force tests are done during manufacturing process per lot according to procedures.On checking the results for these tests on lot 1612256p they are within specification limits.Since no incidence happened during manufacturing process and according to results obtained from test carried out, the samples received meet iso7886 annex d, and it can be confirmed no manufacturing defect has been found on them.So a definitive root cause cannot be determined.Based on severity and occurrence no formal capa is required according to internal procedure.
