apologies if you are already aware of this but with respect to the x5 or greater test current introduced in the 18th, Hager have advised that their RCBO units are manufactured to the 2017 amended version of BSEN61008/9 which permitted disconnection within 40ms at 250mA. Thus they advise testing at x 5 on both sides with the instrument set for 50mA on the variable range.
BS EN 61008 and BS EN 61009 both require RCDs to trip at 300ms or less at X1 I delta n. That is the product standard for the devices. That standard is set out in Table 3A of Appdedix 1 of BS 7671.
BS 7671 does not have a specific regulation for RCD testing test currents or times.
