Exploring Materials, Equipment and Component certification with LR


The Approval in Principle (AiP) process offers technology developers an opportunity to lay out a roadmap for full regulatory compliance by focusing on key issues.

Why an Approval in Principle?

  • You gain early confidence that your technology has the potential to satisfy regulatory requirements
  • Stakeholders will have confidence in their investment
  • It provides you with a statement that there are no major obstacles to future certification or classification
  • You can use it to provide ‘preliminary approval’ or to provide input to preliminary approval

What an Approval in Principle involves

An Approval in Principle is not a guarantee that, despite good engineering practice and judgement, the design will obtain regulatory approval or an assurance that a design can meet any code or standards requirements.

The certificate covers:

  • That there are no conceptual issues related to the design concerning the appropriate regulatory requirements
  • Brief detail of the technology
  • Equipment type, as applicable
  • Operational environment
  • Limitations
