Right - the dop is the first date upon which you MAY employ a new standard for compliance. The dow is the day by which any conflicting (ie the old standard) must be withdrawn and is therefore ineffective. This makes the period between dop and dow a transition period. Typically, the new standard is tougher than the original, so the transition period is used by everyone to ECO their products, retire the dinosaurs, etc. In this case (assuming all the dates are correct and it goes according to the plan), the situation is a bit upside down - A14 makes compliance to EN61000-3-2 easier. The dow for EN61000-3-2 will coincide with the dop of A14, which means on January 1st, you'll need to comply with EN61000-3-2, BUT you'll have the option to use A14 in doing so. For many manufacturers, A14 is the simpler and easier path, so I expect that many will take it once it is available.

For an ammendment it means the part of the old standard that conflicts with the ammendment. >From the doa until the dow you may use either the old unamended standard or the new ammended version. After the cross over period you may use only the new amended version.
