7. Background
At November 2016 WG meeting, three teams were formed for certain clauses:
Team 1 (Clauses 1 to 5)—Heirman leader
Team 2 (Clauses 6 to 11)-Popovici leader
Team 3 (Clauses 12 & annexes)-Harrington
Started with checking the use of “shall” and “should” for normative/informative
PINS approved in November 2017
27 Nov meeting: 36 attendees; 5 hour WG meeting

8. Process Continue aggressive schedule and work
Teams hold webinars approximately monthly
Maintained sequence of team and full WG webinars (roughly one week apart)
“Master” document mashed together so that all teams see the entire document in case changes also apply to other parts of the work.
Presently close to 95 percent completed
WG approved sending the present draft to SC1 to get additional inputs/review—nothing to do with an “approval” vote
Hold WG meetings at C63 meetings such as on Tuesday, 27 November here in Boulder

9. .
Key changes
Clarification on meaning of modal verbs (e.g. shall, should, can, may) and correction of their use all throughout the document
Addition of normative tolerances on dimensional specifications (1.4 and Annex C)
Updates on LISN calibration requirements: addition of phase requirements and updated magnitude requirements for the LISN impedance and removal of the requirements to calibrate the LISN with the extension cord, when used (4.3 and Annex B)
Reformatted the antenna tables (4.5.1).
Updated normative references to their latest editions, including ANSI C63.5, C63.2, and all CISPR references (clause 2)
Clarification on the use and placement of the vertical coupling plane for conducted emissions on tabletop, floor-standing, and combination equipment (5.2.3, 6.4, and 7.3.1)
Removed the site validation option consisting in placing absorbers on the ground plane. All test sites for radiated measurements above 1 GHz must now meet the SVSWR requirements up to 18 GHz (5.5)

10. )
Key changes ). . .
Addition of clear requirements for EUT cable termination and cable type ( and [HP1] )
Addition of requirements for pole-mounted EUT (6.3.6[HP1] )
Updated requirements for EUT arrangement for radiated emissions to account for large systems, with multiple units. The EUT arrangement must be centered onto the turntable (6.3)
Clarification on how the radiated emissions measurement distance is defined, including clear definition of the antenna reference point and boundary of the EUT. Addition of restrictions on possible measurement distances (minimum and maximum), for each frequency range (8.2)
Updated test method for radiated emissions above 1 GHz to account for the antenna beam-width relative to the EUT arragement’s width and height (8.2.5[HP1] 
Addition of requirements for testing EUT with HDMI input (12.2[HP1] ) and HDMI output (12.3[HP2] )
Replacement of Annex D (NSA) by the new Annex D from ANSI C63.4a-2018 C63.4a-2017, with small modifications, such as clarification of the antenna height-scan step size, and addition of website link to utility spreadsheet for calculating theoretical NSA valuses for an ideal site (Annex D)
Updated guidelines on radiated emissions maximization procedures to support reduced test time (Annex E)

Reviewed inputs presented
Opened the draft for comments
Focused on items that needed needed futher resolution and action items
Removed qualitative terms such as “small”, “large”, etc to be sure that requirements are clear

Need for and size of vertical coupling plane for conductive emission testing in a laboratory environment and at open area test site
“Loop back” cable arrangement need and application for various applications including vertical rack drawers/shelves with multiple plug-in with cabling to another unit, overhead cabling, and cabling between units in a single drawer
Coordination with similar requirements in other C63 committees such as C63.5

13. Highlighted Discussion in Boulder)
Highlighted Discussion in Boulder ). . .
Revised antenna positioning requirements for final radiated emission measurements 1 GHz and above to better describe aiming the antenna as its height above the ground plane varies ( )--highlight
Added an option of positioning the receiving antenna horizontal to the ground plane as it is scanned in height when measuring radiated emission measurements in the frequency range 1 GHz to 40 GHz ( ) -highlight

14. Tuesday Meeting Summary
Continued to update the full “mashed up” draft and discussed further changes as needed.
Tentative schedule
Continue to get SC1 inputs
Two webinars already planned: Jan and Feb 2019
When WG resolves issues, ballot to send to SC1 asking SC1 to review it one more time and with the plan to move it on to C63 for ballot
All of the above will be by webinar discussions
Target publication in 2019

ANSI C63.25 WG Validation Methods for Radiated Emission Test Sites
Meeting Update, held at NIST on Nov 27, 2018
Location: 325 Broadway, Boulder, CO
Meeting covers both C and C
Dan Sigouin, Chair C63.25
Greg Kiemel, Vice Chair C63.25

16. Accredited Standards Committee C63® - EMC
C63.25 WG
Family of C63.25 standards:
C (1 GHz to 18 GHz) TDR
C (30 MHz to 1000 MHz) NSA
Future plan for above 18 GHz
C (30 MHz to 1000 MHz) PINS is current
Work on C will begin once C is published…Stay tuned…

17. Accredited Standards Committee C63® - EMC
C63.25 WG
Face to face meeting on Tuesday Nov 27, 2018 was held at NIST in Boulder CO (16 attendees)
C Draft (above 1 GHz) is still at the BSR8/BSR9 stage (will be discussed on upcoming slides)
C (30 MHz to 1000 MHz) PINS is current

18. Accredited Standards Committee C63® - EMC
Status of C (1 GHz – 18 GHz)
On or about November 2017 the C WG submitted the draft to SC1.
Subsequently all comments received were resolved by the WG.
On or about December 2, 2017 the motion at SC1 to approve sending the draft C to the parent C63 main committee passed.  
The draft was circulated twice after two rounds of comments. The draft C ( ) was finally approve by the C63 main committee on March 22, 2018.
In April Jennifer Santulli from IEEE formed a ballot group for C
All comments received were addressed by the WG by July 27, 2018.
The revised draft “C /D1.01, August 2018” was submitted to Jennifer.
BSR-8 was submitted on August 10, 2018.

19. Accredited Standards Committee C63® - EMC
Status of C (1 GHz – 18 GHz) CONTINUED…
On or about October 26, 2018, Jennifer received an enquiry regarding to the process. This put the BSR-9 process on hold.
After receiving no further correspondences, the BSR-9 was forwarded on or about November 2, 2018.
On November 6, 2018 ANSI rejected the BSR-9 C , specifically citing the section 2.6 of the ANSI essential requirements.
On November 8, Jennifer initiated a 10-day re-circulation of the draft C
The re-circulation closed on November 19, 2018.

20. Accredited Standards Committee C63® - EMC
Status of C (1 GHz – 18 GHz) CONTINUED…
Bad news …
Three C63 members provided ‘new’ comments and NOT on existing comments as per the rules of re-circulation.
On Tuesday Nov during the FtF meeting, the group discussed each comment and provided a response for each. Afterwards, a vote was taken on two options in order to move forward.
Option 1: Proceed to re-circulate a revised draft on only the comments provided during the BSR8 process.
Option 2: Move to "reject" all the comments, however provide the response to the comments and consider for the next issue.
The voting process resulted in a majority vote for option 2. The results have been forwarded to Jennifer at IEEE.
The BSR-9 C process should commence once again??
