EMC and Wireless/RF Proficiency Testing [PT] Program
PT Scheme Descriptions
Proficiency Testing is one of the key factors used by laboratory Accreditation Bodies (ABs) and regulators in determining the competency of EMC and Wireless/RF Test Laboratories.
ACIL’s Accredited EMC Proficiency Testing (PT) Programs have been specifically developed to address EMC and Wireless/RF Test Laboratories' needs to participate in one or more relevant Inter-Laboratory Comparison (ILC) “Round-robin” EMC and/or and Wireless/RF proficiency tests to satisfy:
ACE-PT Inc., a wholly-owned subsidiary of ACIL’s Independent Laboratory Institute [ILI], currently operates and administers ACIL’s ISO/IEC 17043-Accredited EMC and Wireless/RF PT Program. Both the ILI and ACE-PT Inc. are IRS 501(c)(3) non-profit institutions.
ISO/IEC 17043-accredited PT Schemes: Two schemes are currently available to participating EMC and Wireless/RF Test Laboratories that wish to evaluate their proficiency in making conducted and radiated emissions measurements. Each EMC and Wireless/RF PT Scheme operates on a perpetually ongoing basis using the “round-robin” approach, with the applicable test artifact being circulated successively from one participating EMC test laboratory to another.
Each PT Scheme is structured as follows:
Each PT Scheme is based upon the use of one specific serial-numbered PT Test Artifact that is continuously circulated in a "Round-robin" way (i.e., from one Participating Test Laboratory to the next, and so on), until PT measurement data from a minimum of 12 participants (but typically from 15 or more participants) have been collected. The measurements from these 12 to 18 participants define a "Round". [Note: Each EMC Test Lab Facility Location that participates can submit results from as many as four participants – i.e., up to four Test Operators at their physical location].
Upon completion of a “round”, the collected PT Measurement Data are statistically analyzed using the "Robust Analysis: Algorithm A" method detailed in ISO 13528:2015 Annex C Clause C.3 to determine the “assigned values”. Then, each participating Test Lab’s measurements are used to compute the corresponding performance statistics (i.e., D-Statistics or deviations, and Z-Scores or Standardized Errors). Next, the Performance Evaluations Parameters (Control Limits) are set using the applicable worst-allowable Measurement Uncertainty values published in CISPR 16-4-2:2011+AMD1:2014, and with the Uncertainty of the “assigned values” computed from the measurement data.
The analysis results of each “round” of the PT Program are afterwards summarized in tabular and graphical form and published in formal PT Analysis Reports within 30 days of the completion of that "Round". In each PT Analysis Report, the identities of each participating Test Laboratory Facility Location (and the identities of each Test Operator) are indicated only by a randomly generated “Lab Code”, thus ensuing confidentiality.
Each Participating Test Laboratory is provided with access to the PT Analysis Report or Reports that contain their PT Results. Additionally, these PT Analysis Reports can be made available (upon written request from a participating Test Laboratory), to their Laboratory Accreditation Body, and/or to regulators and/or clients.
Due to the very lengthy intervals between the completion of two successive "Rounds" for each PT Scheme, much of the value of participation in PT would be lost if each Participating Test Laboratory did not receive its PT Results very quickly. Recognizing this, in every case, ACE-PT Inc. provides each participating Test Laboratory with a formal Interim "Statement of Performance" Letter detailing their PT Results in 7 days or less after they have submitted their complete set of EMC PT Test Data to ACE-PT Inc. With prior arrangement, when necessary, 24 hour turnaround (expedited service) is available at no additional cost.
Registration and Pricing
Registration for each of ACE-PT Inc.'s PT Schemes is available separately, on a first come, first served basis. ACE-PT Inc.'s PT Schemes are available to participating EMC and/or Wireless/RF Test Laboratories located anywhere in the world. On-line registration is required.
All of the currently available ISO/IEC 17043-accredited PT Schemes offered by ACE-PT Inc. are priced identically, as follows:
Lab/Additional Participant Fees:
Pre-payment of all fees is required in order to Register for any of ACE-PT Inc.'s PT Program Schemes. The preferred method of payment is by Credit Card (i.e., MasterCard, VISA, or American Express). If necessary, payment can be made by domestic or international wire transfer, with the participant being responsible for all fees associated with sending and receiving the wire transfers. All payments must be made in US Dollars.
Participants located in North America are responsible for the cost of shipping the PT Test Artifacts(s) onward (via express carrier - e.g., FedEx ®, UPS ®, DHL®, etc) to its next destination. Participants located outside of North America are responsible for the cost of shipping the PT Test Artifacts(s) both ways (via express carrier - e.g., FedEx®, UPS ®, DHL®, etc) from the point of origin to the next destination.
