Responsibilities of an ISO 17025 lab about informing clients if its accreditation is in jeopardy

You asked

"Does an ISO 17025 accredited lab have the responsibility to notify its clients if its accreditation is in jeopardy for whatever reason as noted in NEI14-05A (e): The customer must be notified of any condition that adversely impacts the laboratory’s ability to maintain the scope of accreditation. Is this type of statement in the ISO 17025 documentation or is it implied?"

It seems the situation refers to laboratory that was accredited and is able unable to keep accreditation for a method? In that case it is necessary to remove that activity from your scope. All accreditation bodies have policies related to statements and claims that laboratories can make regarding accreditation. It is the responsibility of the laboratory to comply with those requirements.

The accreditation body must be informed. As ISO 17025 accreditation is an assurance to customers, it would be misleading not to inform them. There is however no regulation in 17025 that states that you must inform them.  Note that what is required by 17025, is to comply with reporting requirements of clause 8.7 so your statements and disclaimers on your report would need to change.
