Please refer to our disclaimer . Note that all componentry must comply with the standard requirements .
End users / specifiers still retain responsibility for checking the SANS certificate and particularly the supporting documents that are an integral part of the certificate .
Where there is no SANS designation , we still list the four valves on the matrix . PA
