For Europe, what is the difference between (a) the date published by CENELEC as the Date of Withdrawal (DOW), and (b) the Date of Cessation of Presumption of Conformity published in the EU Official Journal (OJ) associated with the EU LVD?
You asked what the difference is between DOW as published by CENELEC and the Date of Cessation of Presumption of Conformity published in the EU Official Journal (OJ) associated with the EU LVD. To simplify things;
- Think of the CENELEC DOW as a date used for standardization purposes. The date (DOW) published on the CENELEC website (and in the EN standard) is the final date as of which the legacy versions of the standard(s) will be withdrawn and replaced by the latest standard. This date is assigned/associated with the latest standard, although it in reality provides a sunset date for the previous (legacy) standards. Until this date, both the legacy standards and new standards can be considered active for purposes of standardization. After this date, only the latest standard is active.
- Think of the date published in the EU Official Journal (OJ) as the regulatory/legal date(date of cessation of presumption of conformity) if a manufacturer wants to use the standards path to demonstrate presumption of conformity with a Directive, such as the Low Voltage Directive (LVD). Per the LVD’s published list of standards, its Note 1 (summary list of titles and references of harmonised standards under Directive 2014/35/EU for Low Voltage) states, “Generally the date of cessation of presumption of conformity will be the date of withdrawal (“dow”), set by the European standardisation organisation, but attention of users of these standards is drawn to the fact that in certain exceptional cases this can be otherwise.” Therefore, sometime after CENELEC publishes the DOW, the Date of Cessation will be announced in the EU OJ, which usually is aligned with the DOW, but there (rarely) can be differences. As of this date published in the EU OJ, to legally place a product covered under the scope of the standard on the market, it should meet the latest standard if the manufacturer will be using the standards path to demonstrate conformity with a directive, such as the LVD.
