We cannot, it is heavily copy restricted, you will need to register, it is free to register though.

IET Wiring Regulations updates - IET Electrical

cheers just registered , how can they change the Zs values , so you have just finished a job and the zs values just meet the regs , in 5 years time the eicr they will not

On an EICR although we test against current regs in force at the time, they are not retrospective, so if it was originally done correctly to 17th pre-amd3 you could not fail it due to it not complying to 17th amd 3, it would be either no code (with a note), or maybe a C3 depending.

so if you are doing a eicr and the zs values dont comply you put a c3 , i am not questioning you just asking as i dont have a lot of experience in testing

On most EICR forms there is a box to fill in which states what edition/amd the installation complies/is installed to (if known).

If it is correct to that edition then it may not need a code at all, since they done away with the old code 4, you as the inspector would need to decide whether it warranted a code at all.

Some guidance is given in the ESC guides and other publications on how to deal with installations to earlier editions such as no RCD protection etc., but obviously as amd3 has not been finalised we have no guidance at the moment.
I would expect further guidance in due course.
