My comment was a bit off-topic.
What I want to say is that if your quality system is IATF and you do not apply it for non-automotive parts that can lead to a non-conformity in a ISO 9001 audit for the non-automotive parts since you are not respecting your own quality system.
Therefore your non-automotive parts will have same system requeriments than your automotive parts.
Regarding the question of the OP if your product is applied to automotive industry and you have to go through an IATF audit you must include the customer. The auditor must target only the references related to automotive industry.

This is simply untrue!!! An ISO audit cannot write a non-conformity because the company is not applying IATF requirements to non-automotive products!!! Period!
And no non-auto products would not have the same requirements!!
