EMC and Wireless/RF PT Schemes Registration
Share |

As of March 2017, ACE-PT Inc. has two ISO/IEC 17043-accredited EMC and Wireless/RF PT Schemes available. These are as follows (click on each scheme to register and make payment):


ANSI C63.10-2013 / ANSI C63.4-2014 (150 kHz – 1 GHz) PT Scheme
ANSI C63.10-2013 / ANSI C63.4-2014 (1 GHz – 18 GHz) PT Scheme

By the act of registering to participate in any of the ACE-PT Inc. PT Schemes, you acknowledge that you have explicitly agreed to follow our Ground Rules. (See Below)

“Ground Rules” that must be followed for successful PT Program Participation.

In order to ensure that each "round" of each PT Scheme runs smoothly and without excessive delays, the following procedures shall be strictly adhered to:

  1. Before doing anything else, make certain that each test operator (i.e., test technician or test engineer) who will be making PT measurements has carefully READ and UNDERSTOOD the USER INSTRUCTION MANUAL and any IMPORTANT NOTICES that are included in the Transit Case with the EMC PT Test Artifact. The USER INSTRUCTION MANUAL (and any IMPORTANT NOTICES) contain very detailed and specific instructions. If these instructions are not followed correctly, you will most likely "fail" your PT.
  2. Each participating EMC Laboratory is required to report its results using the ACE-PT Inc.-provided Spreadsheet Template (written in Microsoft® Excel® 2007). Due to the very large volume of data generated during a PT Scheme "round", "Paper" submissions of data cannot and will not be accepted. Your results must be submitted by e-mail to the following address: rbright@acil.org.
  3. Each participating EMC Laboratory facility has the option to submit results from as many four different "operators" (i.e., test technicians and/or test engineers) during each week of EMC PT Testing. Each participating EMC Laboratory facility will therefore be required to submit one completed Spreadsheet Workbook for each different "operator". When entering data into each Spreadsheet Workbook, the "operators" will be identified only by an operator number - i.e. Operator 1, Operator 2, etc.. It is the responsibility of the participating EMC Laboratory facility to keep track of the actual identities of their three Operators.
  4. When making EMC PT Scheme measurements, it is critical to prevent collusion as well as any other activities that that compromise the integrity and/or the statistical independence of the measurements.

    In the context of proficiency testing, the term "collusion" defined as an unacceptable process by which two or more participants compare their data (and possibly) change their data so as fit a result that is "believed correct".

    Collusion negates the objective that underlies all proficiency testing programs, which is to provide an objective means for the comparison of each participating laboratory’s performance with the performance of the other participating laboratories. Collusion between participants constitutes fraud.

    In particular, the managers at each participating EMC Test Lab facility must prevent the following kinds of collusion from occurring: "group testing", "contingent testing", and "duplicate testing". "Group testing" occurs if more than one operator is involved with making a single set of measurements on the EMC PT Test Artifact. "Contingent testing" occurs if one person sets up each test, and then some or all of the "test operators" use that setup to make their measurements. "Duplicate Testing" occurs when the same operator measures the EMC PT Test Artifact more than once and reports the results as if he/she were two or three different operators. "Group testing" and "contingent testing" can happen innocently, but "duplicate testing" is never the act of an innocent person. In other words, the rule is: one "test operator" collects and reports one complete one set of EMC PT measurements. NEVER submit duplicate results.
  5. To the extent possible, treat the PT Test Artifact as if it were a normal EUT being tested in accordance the EMC Standards that are applicable to the PT Scheme that you have chosen to participate in. Except as specifically required in the applicable User Instruction Manual, do NOT use any special test procedures or test methods.
  6. Treat the Test Artifact gently. It can be easily be damaged or destroyed by rough and/or careless handling.

    For the York CNE II Test Artifact, please note the following:
    1. The circular monopole antenna supplied with the York CNE III for making Radiated Emissions measurements is extremely fragile.
    2. DO NOT USE pliers, a Leatherman® Tool, or an adjustable wrench to install or to remove coaxial cables, attenuators, coaxial adapters, the LISN adapter, and/or, the monopole antenna from the York CNE III Test Artifact.
    3. The York CNE III requires the use of disposable "C" Cell Batteries. When installing or removing these batteries, please be careful not to cross-thread the black plastic battery caps on the York CNE III.
    4. Install the required batteries in the correct manner. The York CNE III Test Artifact requires four disposable "C" Cell Batteries for its operation. DO NOT USE Rechargeable batteries! You (and NOT ACE-PT Inc.) are responsible for providing these batteries. Insert the correct batteries (i.e., new, unused disposable "C" Cells) with the + terminals of the Batteries facing "up" before testing. Please be careful not to cross-thread the black plastic battery covers on the York CNE III. If more than one test operator at your facility is going to use the York CNE III, be sure to replace all of the used batteries with new, unused batteries before that test operator starts testing.
    5. The York CNE III Test Artifact must always be shipped without batteries to preclude shipping damage. Upon completion of testing at your EMI Test Laboratory facility, remove and discard the batteries.

    For the WD Test Solutions EM-18 Test Artifact, please note the following:

    1. The RF Output Connector on the WD Test Solutions EM-18 Test Artifact and the “rubber duck” stub antenna supplied with the WD Test Solutions EM-18 for making Radiated Emissions measurements both have precision SMA-type connectors that can easily be damaged. Avoid over-torqueing or cross-threading these RF Output SMA connectors, especially when installing the provided stub antenna for Radiated Emissions measurements, and, when installing or removing the attenuator(s) and coaxial cable(s) used when making Direct Antenna Conducted Emissions measurements.
    2. DO NOT USE pliers, a Leatherman® Tool, or an adjustable wrench to install or to remove coaxial cables, attenuators, coaxial adapters, the LISN adapter, and/or, the monopole antenna from the WD Test Solutions EM-18 Test Artifact.
    3. Be certain that the internal battery pack in the Test Artifact is fully re-charged before each operator uses it. The WD Test Solutions EM-18 User Instruction Manual and the accompanying Important Notices document gives full details on how to determine if the Test artifact has a "full charge". Do NOT rely on the status LED indicator in the On-Off Switch of the Test Artifact. After each use, a 4 to 8 hour re-charging cycle will be required.
  7. Submit your data by e-mail within two weeks if possible and within 30 days at the latest after completing you PT measurements to the ACE-PT Inc. PT Program Coordinator (Mr. Richard Bright). Your results will be checked when they are received to ensure that the Test Artifact is continuing to operate properly. The e-mail address for submitting your results is: rbright@acil.org
  8. Keep your measurements strictly confidential. They are not to be shared with anyone outside your own Test Laboratory until the completion of the "round". Your data will be held in confidence by ACE-PT Inc. as well. You will receive an Interim "Statement of Performance" letter within 1 week after you successfully submit your PT data. The final PT results from all of the participating Test Labs will only be released after the completion of the current "round" when the final PT Analysis Report is published. The PT Analysis Report will NOT disclose the identities of the participating Test Labs. Full details of the procedures that will be followed to ensure the anonymity of each participating Test Laboratory facility and test operator are provided in the applicable User Instruction Manual.
  9. Store the Test Artifact correctly when it is not in use:
    1. When not in use, the York CNE III Test Artifact should be stored (without batteries) in its Transit Case along with the circular monopole Antenna, the shoulder strap for the Transit Case, this User Instruction Manual, and the CD-ROM containing the PT data collection Spreadsheet Template. Store it in a place where it will not become wet from immersion or from exposure to rainwater, and where the temperature and relative humidity are typically in the ranges of approximately 65o F to 75o F (18o C to 24o C) and 20% and 70% (non-condensing) respectively.
    2. When not in use, the WD Test Solutions EM-18 Test Artifact should be stored in its Transit Case along with the stub Antenna, the Battery Charger Unit, this User Instruction Manual and the accompanying Important Notices document, and the CD-ROM containing the PT Data Collection Spreadsheet Template. Store it in a place where it will not become wet from immersion or from exposure to rainwater, and where the temperature and relative humidity are typically in the ranges of approximately 65o F to 75o F (18o C to 24o C) and 20% and 70% (non-condensing) respectively.
  10. Pack the Test Artifact correctly for shipment:
    1. When you are finished with the York CNE III Test Artifact, MAKE ABSOLUTELY CERTAIN THAT YOU HAVE REMOVED ALL BATTERIES and then place it into its Transit Case along with the circular monopole Antenna, the shoulder strap for the Transit Case, the Instruction Manual, and the CD-ROM containing the Spreadsheet template. Finally, place the Transit Case in the custom-constructed cardboard box that it came in.
    2. When you are finished with the WD Test Solutions EM-18 Test Artifact, MAKE ABSOLUTELY CERTAIN THAT THE POWER SWITCH IS IN THE “OFF” POSITION before placing it into its Transit Case. Then, place the stub Antenna, this User Instruction Manual and the accompanying Important Notices document, and the CD-ROM containing the PT Data Collection Spreadsheet Template into the Transit Case. Finally, place the Transit Case in the custom-constructed cardboard box that it came in.
  11. Send the box via UPS® or FedE or DHL® Insured for $1,000 to the next location, with an “adult signature” required upon delivery. The ACE-PT Inc. PT Program Coordinator (Mr. Richard Bright) will advise you of the name, address, and phone number of the recipient and the urgency of the shipment (e.g., Overnight, 2-Day, 3-day, etc). You are responsible for the cost of the "outbound" shipping cost (including the cost of insurance in the amount of $1,000).
