westfield emissions

Hi all i have a test to do on a 06 westfield i have no info on v5c about emissions so looking at this section of the manual i should use default limits relative to vehicles age (see below) which would be a cat test but this vehicle has come out the factory without a cat or lambda on??? i have tried this vehicle on a bet test and it does pass but i have the problem of there not being a cat fitted and vehicle qualifying for a cat test? Things are a little grey for me on this one and i feel the manual doesn't really help me out any advice greatly appreciated.








 "Test Kit cars and amateur built vehicles first used on or after 1 August 1998 are required to obtain either Single Vehicle Approval (SVA) or Individual Vehicle Approval (IVA) and should be tested to the limits stated on the vehicles V5C. Where no limits are stated on the V5C, or no V5C is available, default limits must be applied relative to the vehicle date of first use".
