Testing & validation

In-house test facilities, not a subcontractor's certificate.

Fire-safe, cyclic, cryogenic and fugitive emission testing all run on our own rigs, which is what lets us validate a prototype and then hold the same standard in production.

  • Training on new revisions, changes and addendums to relevant codes and specifications
  • Practical training for employees directly involved in manufacturing, inspection, testing and quality assurance
  • Internal knowledge-sharing sessions to translate standard changes into shop-floor practices and procedures
  • Regular reinforcement of quality requirements, inspection criteria and documentation practices
  • Role-specific training to ensure that every person understands how changes in standards affect their work

Our commitment is simple: every person involved in the process is trained, updated and equipped to deliver consistently to the required quality standards. SERINO — Quality through Knowledge.
