r1 r2 testing on micc cable

[stylus]

when testing micc,pyro cable for r1 r2 values is it correct to use sheath as the r2 for a 2 core ?

Yes. thats fine.

These are the sheath CSA's that you will need to note on the test form......

Thanks for that Lenny, may be usefull in the future.We just write 'MICC' or 'sheath', and have never been picked up for it, do you always write the size, or a combination of the two?

 

[Guest123]

Usually put MI, and then the size, boxes just aint big enough though.
