Comment (Required)
This clause requires; For Plate Heat Exchangers that include a double wall the failure of one wall shall be visibly evident.
Question:
-Which wall? presumably the wall that cannot contaminate the water supply?

-Is this Specification just for double walled Plate heat exchangers or also for single Plate Heat Exchangers. If it is also for other configurations such single wall Plate heat exchangers is there any provision in this document?
- should the heat exchanger plate failure requirements be in 8.1 ( End Connectors) or in a separate clause (8.2 ? )
- Is it ok for the design requirements to be 2 sentences? Surely there is more information that could be included in this specification?
Proposed change
Include supporting documentation for the above questions.
