  1. Perhaps link the background section to the History of the metric system using {{main}}
  2. Can a citation be added for the paragraph concerning the setting-up of the CGPM, CIPM and BIPM?
  3. "In 1889 the CGPM took delivery" - what does "took delivery" mean?
  4. "the mandate of the CGPM was extended to provide standards for all units of measure, not just mass and length" - before reading this, it is not clear that the three organisations only dealt with mass and length; please make this explicit earlier on.
  5. "In the ensuing years" - vague. Is there a known end date?
  6. Can you explain how the conditions set by the General Conference were not fully met?

I have taken on board your proposals and have implemented them. I have also ensured that the date passed to the accessdate parameter is consistent across all citations. Martinvl (talk) 10:49, 21 June 2013 (UTC)[reply]

Continuing...

  1. It is not stated in the background section that/when the speed of light was fixed.
  2. Is "an elementary charge" correct, or should it be the elementary charge?
  3. Please provide a citation for the current definitions of the base units.
  4. There are some great analyses about the consequences of the redefinitions (eg effect of amp redefinition on vacuum permeability, vacuum permittivity and impedance of free space), but it is not all referenced
  5. Ditto with the example of potentially defining kg from G - WP:OR
  6. Who is Leonard?
GA review (see here for what the criteria are, and here for what they are not)
  1. It is reasonably well written.
    a (prose): b (MoS for lead, layout, word choice, fiction, and lists):
  2. It is factually accurate and verifiable.
    a (reference section): b (citations to reliable sources): c (OR):
  3. It is broad in its coverage.
    a (major aspects): b (focused):
  4. It follows the neutral point of view policy.
    Fair representation without bias:
  5. It is stable.
    No edit wars, etc.:
  6. It is illustrated by images and other media, where possible and appropriate.
    a (images are tagged and non-free content have fair use rationales): b (appropriate use with suitable captions):
  7. Overall:
    Pass/Fail:

I have taken the liberty of replacing bullet points with numbers to simplify cross-referencing of comments.

The outstanding issues in the first set of comments have been handled as follows:

  • Item 4: In this change, the text "under which three bodies were set up to regulate units of measure that were to be used internationally." was replaced by "under which three bodies were set up to take custody of the international prototype kilogram and metre and to regulate comparisons with national prototypes.[1],[2]" Martinvl (talk) 15:00, 24 June 2013 (UTC)[reply]
  • Item 5: The updated text reads: "In 1921 the Convention of the Metre was revised and the mandate of the CGPM was extended to provide standards for all units of measure, not just mass and length. In the ensuing years the CGPM took on responsibility for providing standards of time (1956), electric current (1946), temperature (1948), molar mass (1971) and luminosity (1946)."

The issues raised in the second set of comments have been handled as follows:

As each item is addressed, it will be signed.

Also note the contradiction "In 1960 the metre was redefined in terms of the speed of light, making it derivable from nature" in the lead vs "Similarly, the 17th CGPM (1983) replaced the 1960 definition of the metre[Note 2] with one where the metre is derived from the speed of light" in the background section.

Thank you for spotting this - I have corrected it.
When trying to find out more about Leonard, I discovered that a lot more discussion material had become available, so I am rewriting the final section which I am calling "Discussion" rather than "Criticism". I hope to have it in place in a few days. Martinvl (talk) 06:44, 26 June 2013 (UTC)[reply]
Sounds great! Take your time - no rush. Adabow (talk) 07:38, 26 June 2013 (UTC)[reply]
Hi Adabow,
I have now completed my revisions following your initial review and when you are ready, I would be grateful if you could assess my latest offerings. Martinvl (talk) 20:49, 3 July 2013 (UTC)[reply]
There is still no explanation for who Leonard is. Ditto for Chyla. When someone is mentioned, there first name should be included in the first instance. If the first names are not known, then please at least give initials. Affiliation should be given as well. Adabow (talk) 23:27, 4 July 2013 (UTC)[reply]
Done. Reading between the lines Chyla appears to be a freelancer so his affiliation carries no weight, however the journal where this paper was published referees its papers, so that has been included in the text (complete with Wikilink).

OK, everything looks good to me now. Passing. Well done. Adabow (talk) 10:45, 5 July 2013 (UTC)[reply]
