10 2007 CANENA Annual General Meeting CANENA Annual General Meeting Day 1: Frustrating meeting! “AWG is a backward step”. “North America is not Globally Relevant”. “Conductor size is not an Essential Difference - just change to Metric”. After much heated discussion - Study Group Proposed.
11
11 2007 CANENA Annual General Meeting CANENA Annual General Meeting Day 2 Study Group approved. SG chair - Reimer Stubbe, Germany. – the most vocal objector from day 1! Chair from WG 19 Mark Coates – UK. Cenelec representative (Steve Mason – UK). N America (Ron Lai US, Richard Barker US). European (Gerhard Novac IT). Non European (Antony Falconer ZA).

12 2007 CANENA Annual General Meeting CANENA Annual General Meeting Inaugural Study Group meeting – Paris, May 2005. 2 nd edition of 60228: (1978). Restricted to 4 classes. Reduced number of sizes. Deleted AWG. 3 rd edition of 60228: (2004). Size based on DC resistance. Decision to be a consensus driven group ( EDR on hold ). Only conductors for power and control cables. Comments and minutes issued to North American countries.

13 2007 CANENA Annual General Meeting CANENA Annual General Meeting Delay……... Attempt to call a meeting at Nov 05 Milan WG meetings – Failed. Comments on meeting minutes from USNC forwarded to IEC.

15
15 2007 CANENA Annual General Meeting CANENA Annual General Meeting Second Study Group Meeting – Paris, May 2006. Three part approach: Publication of 60228 as a technical report. Addition of AWG as “Part 2” of 60228. Merging of both parts to one. Study group consensus reached. Survey of IEC Member Countries proposed. Sept. 2006 - Study Group Activity Report issued to TC20 for London Biennial meeting approval. Work commenced on Technical Report pending approval of SG report from TC20 committee
16
16 2007 CANENA Annual General Meeting CANENA Annual General Meeting TC-20 Biennial meeting, London, Oct. 2006. Friendly welcome and US officially thanked for participation at WG level (since Berlin). SG Report presented by Cenelec Representative (Steve Mason UK). Proposal (Belgium) to have unique TR number not IEC 60228 Part 2 to prevent roll-on effect to other standards. All unanimously accepted. Survey dropped as redundant.
17
17 2007 CANENA Annual General Meeting CANENA Annual General Meeting TC-20 Biennial meeting, London, Oct. 2006. Unconfirmed minutes issued Nov 2006. Step 1 Technical report 1Q 2007 (WG19) with metrification of size via DC resistance. Step 2 Technical report number to be retained for a “publication” with an “informative” reference in IEC 60228 (2010)(start 2007). Step 3 Harmonization of “publication” and IEC 60228 (2015 or 2020). This has caused some confusion that will be addressed in London March 2007 (WG19). There is a need to read SG report alongside the minutes.
