Validation of Medical Device manufacturing line for getting the European CE mark certification.

Validation Of Medical Device Manufacturing Line For Getting The European CE Mark Certification.


In order to obtain CE mark certification for an innovative medical device, the Medical Device company was required to perform Validation of the production line with their subcontractor (CMO).

The production line

The device production line includes either automatic and manual processes: soldering stations, visual tests (according to IPC A 610 standard), assembly, and gluing stations. Besides, there are machines for cutting and exposing electrical wires, plastic pipes, a laser soldering machine, packing machine. The line includes various jigs and aids for assembly.

Skills and people required for this project

  • Experienced process validation engineers, with in-depth knowledge of medical device regulatory requirements for process and software validation: GPSV, GAMP 5, 21 CFR part 11, part 820, cGxP, GHTF, ISO 13485:2016, CSV, and more.
  • Ability to learn quickly and control all tasks and perform them while fully communicating with all relevant parties according to both Quality Departments (CMO’s and customer’s).
  • Ability to identify the gaps between the various requirements for the situation on the ground, to identify the potential risks, and provide the solutions.

The steps of the project

  • Carrying out a pFMEA risk assessment together with the customer team.
  • Preparing the Validation Master Plan including the equipment in the production line, the software at the test stations, and the process validation.
  • Preparing specification documents for the stations (URS and SW).
  • Working with the customer’s statistics department and writing Test Method Validation (TMV) protocols, choosing a validation strategy according to the nature of the GR&R / attribute / variable test, the number of samples, the number of operators, and the number of repetitions required. Analysis of the results in statistics software to complete a final report.
  • Writing Protocols and Final Reports IQ, OQ, PQ, TMV, CSV.
  • Reviewing and updating drawings.
  • Aligning and adapting the line to the requirements, the various test stations were upgraded to meet the level of reliability required for Test Method Validation (TMV).

In conclusion

The company received the CE mark and began to successfully market its device in Europe.

The Process Validation project was done on a tight schedule of about 4 months; saving the company several months due to the experience and knowledge of the RS NESS’s engineering team.
