Light bulbs
[edit]I changed the data for light bulbs (diff), including the tabulated percentages:
Old table: Light bulbs; relative energy consumption | ||||||
A | B | C | D | E | F | G |
20–50% | 50–75% | 75–90% | 90–100% | 100–110% | 110–125% | 125% |
New table: Light bulbs; relative energy consumption | ||||||
A | B | C | D | E | F | G |
<18–25% | <60% | <80% | <95% | <110% | <130% | >130% |
The old percentages were, apparently, copied from http://www.energy.eu/focus/energy-label.php , but the values there are different from the official EU directive. Can anybody confirm that the 98/11/EU directive is the latest status? Han-Kwang (t) 21:23, 17 May 2012 (UTC)
Television example
[edit]- a television with a diagonal of 82 cm (32 in) has a screen area A = 64 dm2
This example isn't in the EU regulation. Perhaps dm^2 should be spelled out as square decimetres? But how do you reach 64? If it's a 9:4 aspect ratio, that's about 720mm x 320mm, which is more like 22 dm^2 --78.145.16.92 (talk) 14:26, 12 June 2012 (UTC)
- Hmm, I wrote that example, and it looks like I had a brainfart. For a 16:9 ratio, you would have 4.0x7.1 dm^2 = 28.7 dm2. I corrected the article. I'm not sure what you mean to say by 'this example isn't in the EU regulation'. Han-Kwang (t) 14:02, 13 June 2012 (UTC)
How to calculate EEI
[edit]OK, I've been to this article before, in search of the accurate calculation method of the EEI. This is important for everyone, because sometimes incomplete data is available, and we either need to calculate the EU energy class, or the expected kWh in consumption. We also need to compare how the capacity (defined differently based on context) affects kWh, even though the energy class remains the same. So, can someone please find how the EEI is calculated in every scenario? — Preceding unsigned comment added by 91.140.109.87 (talk) 09:01, 23 January 2017 (UTC)
Formulas for calculating the EEI are given in each Directive (or Delegated Regulation) usually in one of the Appendixes/Annexes, near the end of the regulation. Strangely enough, the logical order in which the matter should develop is somehow reversed, but you will learn to live with it...
For example the "Commission Delegated Regulation (EU) No 874/2012"on{{cite web}}
: CS1 maint: postscript (link) electrical lamps at Annex VII, page 19, defines the reference power Pref as the electric power able to generate a luminous flux Φ (when Φ < 1300 lm)
This is the definition of the power that corresponds to EEI = 1 for a given luminous flux Φ. If your real lamp has Φ = 740 lm and P = 12 W (that is a fifth of Pref or 0.20·Pref since Pref(740 lm) = 60.2 W), then its EEI = 0.20, and its energy class will be A (see Annex VI, page 18).
Hoping the matter is a bit clearer now.

Implementation
[edit]I would like the article to explain how this is implemented. What is the specific role of the governments in setting the standards, testing the items, enforcing the labeling, etc. What entities, public and private, are involved? Also, how is all of that funded?Dicirnah (talk) 19:08, 26 April 2017 (UTC)
Nonesense!
[edit]"For refrigerating appliances, such as refrigerators, freezers, wine-storage appliances, and combined appliances, the labelling is specified in terms of an energy efficiency index EEI, which is an indication of the annual power consumption relative to a reference consumption that is based on the storage volume and the type of appliance (refrigerator or freezer)."
Are they trying to say that an A++ fridge/freezer, with the same capacity, will be as efficient in Spain as it is in England? Quoting an annual power usage for a fridge is ridiculous! — Preceding unsigned comment added by 86.25.94.142 (talk) 17:26, 8 August 2018 (UTC)
Spelling variety
[edit]In March 2007, this edit included the addition of the clause "the drum capacity in kilogrammes". That was the first time that unit was used in the article, and subsequent additions used the same variety of English. That then would seem to be the baseline by which we can apply MOS:RETAIN, which states: When an English variety's consistent usage has been established in an article, maintain it in the absence of consensus to the contrary.
That is why I reverted this edit. -- DeFacto (talk). 14:50, 27 July 2019 (UTC)
- The correct spelling is kilogram. Or rather, that spelling is recognized in all variants, and is therefore preferred. Dondervogel 2 (talk) 12:49, 28 July 2019 (UTC)
Dishwasheres really suspicious
[edit]It seems to me that diswashers part swapped new and old labeling. They used to hava A+++ etc, but according to new rules there should only be A-G letters. BUt the article states otherwise. Gorn (talk) 21:16, 19 October 2021 (UTC)
