Wendy, Intermediate checks means verification between calibration intervals. You need to be sure your equipment is working properly at regular intervals. The intent is to reduce the impact and magnitude of an equipment problem during a verification or calibration. If you do not check your equipment through verification and a problem is found during your annual calibration, then the magnitude of the problem is a whole years worth of projects that have to be investigated. Talk about tedious work!
If you had weekly or monthly checks of the system then you have a reference point in time that you know the equipment was good. So the magnitude of the problem is from the time the problem was discovered back to the last time the equipment was determined to be good through verification. Which hopefully is measured in days, or at worst a few weeks depending on your verification cycle. Hope this covered your question… Kind Regards, Sam Wismer Technical Director ACS, Inc. *Tel: (770) 831-8048 *Fax: (770) 831-8598 *Web: <BLOCKED::http://www.acstestlab.com/> www.acstestlab.com *Email: [email protected] <BLOCKED::mailto:[email protected]> ****************CONFIDENTIAL**************** This e-mail and any attachments may contain information which is confidential, proprietary, privileged or otherwise protected by law.

Org Subject: ISO 17025 Section 5.5.10 Intermediate Checks Dear All, I am preparing my laboratory for accreditation. Referring to ISO 17025 Section 5.5.10 Intermediate Checks, I am uncertain on the extent of checks required. For example, IEC 61000-4-11 Section 6.1.2 Verification of the characteristics of the voltage dips, short interruptions generators states that “the generator characteristics has to be verified according to ……”. Does the intermediate checks mention in 17025 coincides or refer to such tedious work? Or does this verification actually means ‘calibration’? What is the extent of intermediate checks required by ISO17025? Appreciate advice from those who works in an accredited EMC lab. Thanks.
