18th Edition, puzzled about certain question

[The Ghost]

So I had this question in mock exam, got mine tomorrow, the real one.
The external influence code ACM requires IP rated equipment to
IPX1
IPX4
IP0
IPX2
Answer IPX4 apparently. But I could not find the corresponding external influence and presume it is a typo? I don't want to encounter this tomorrow and flounder around on the basis of a typo.

At least someone noticed ACM being not in the book. It is a type right?

 

[The Ghost]

the code AC

Yes but what does ACM relate to?

It is a common typo on mock papers going back to the 17th. So the mock you are doing is very old.

I’ve got all the literature from my local college. On their website, the FAQ says “can I take notes into the exam?”
The answer:
“Yes. It is an open book exam. You should take a copy of BS7671 17th edition Amendment 1”

The FAQ is a few years out of date then.

I’ve never heard of ACM either.

I have just done it today with some mock questions which had errors, don't worry.

Wouldn't be right without a few mistakes here and there...
Some things never change .

I had this question on my actual 17th amd3 exam, but my tutor had already told us the answer was IPX4, he also believed it was a typo so they told everyone taking the exam the correct answer.
