Dear John, Thanks for your additional view!
Actually, IEC amendment 2 of 60335-2-24 consists of not only the incombustible material for back panel. It also has other measures to address the fire risk. In addition, metal back is not a mandatory requirement in both IEC and UL standards although LFB expressed to the public with a simple description of US metal back. Metal back is one of options and normally taken on US fridges. IEC amendments consist of additional requirements, stringent requirements over previous ones and corrections. Incombustible material back is an additional requirement. IMO it had better to quote both EN and IEC A2 amendment under LVD applicable standards. IEC amendment A2 is being challenged not only by UK but also other countries. We have to wait the outcome before moving to next step.

It would be better to write 'but in addition' rather than 'except', since a metal back also meets the defective requirement in Section 24. 'Except' gives an immediate impression that some requirement of the standard is *not* met. With best wishes DESIGN IT IN!

In general, I structure the report to follow the statements on the face of the Declaration. In this case, I suggested declaring compliance with 60335-2-24 with exceptions. So, I'd have substantive remarks at the appropriate section or sections of the 60335-2-24 checklist, with the substantive remarks describing how the article or test protocol deviates from the standard and WHY. If the risk assessment has a part relating to fire, and the approach taken is usually limited to "see 60335-2-24 checklist" (fire being possible due to MANY factors), I would either say nothing different - the substantive remarks under the standard speak for themselves - or I would amend the remarks to "meets 60335-2-24 except [cite ONLY clause number where the substantive remarks were recorded]." It would be nearly as convenient if the reverse practice was followed. That is, have the substantive remarks in the risk assessment, and then in the related part or parts of the 60335-2-24 checklist, refer to that specific part of the risk assessment. In addition to trying to make a "substantive observation of interest" easy to find, another principle I try very hard to follow is to limit detail design or execution observations to ONE PLACE in the report, and then refer to that part as needed. That way, if the report is amended to reflect a revised design, there is less risk of having inconsistent observations recorded in the report.
