WHAT DOES THIS STANDARD COVER?
A Network Rail document recorded as covering coating and sealant assessment, testing, certification, registration and specification.
WHY IS IT RELEVANT?
Relevant as context when considering how coating-system assessment and certification may be governed within Network Rail work. It does not itself confirm a current approved coating system or project requirement.
KEY INSPECTION CONSIDERATIONS
Confirm the applicable current Network Rail and project documents before using assessment or certification information in inspection planning, reporting or acceptance decisions.
WHAT THE STANDARD SHOULD NOT BE USED TO ASSUME
Replacement of an earlier recorded issue should not be treated as proof that the recorded replacement remains current. Certification context is not equivalent to project acceptance.
PRACTICAL INSPECTION APPLICATION
Use this record to identify potential certification and assessment context, then confirm the controlling current documentation and project-specific specification.
