In exceptional and duly justified cases, such as reaching insufficient savings across the full spectrum of the seven classes, the label should be able to contain fewer classes than a regular A to G scale. In those cases the dark green to red colour scale of the label should be retained for the remaining classes and should apply only to new products that are placed on the market or put into service.
I gcásanna eisceachtúla, cuí-réasúnaithe, i gcás mar shampla nach mbainfí amach coigilteas leordhóthanach thar réimse iomlán na seacht n-aicme, d'fhéadfadh sé go mbeadh níos lú aicmí ar an lipéad ná an gnáthscála A go G. Sna cásanna sin, ba cheart an scála dathanna dúghlas go dearg a choinneáil ar an lipéad don chuid eile de na haicmí uachtaracha agus ba cheart nach mbeidh feidhm aige ach amháin le haghaidh táirgí nua atá á gcur ar an margadh nó á gcur i seirbhís.
