ANNEX II

Templates for statements of conformity

1. General requirements

1.1. The statement of conformity shall consist of two sections:

1.2. When delivered on paper format, the statement of conformity shall be no bigger than A4 paper format (210 × 297 mm).

1.3. All information on the statement of conformity shall be provided in ISO 8859 series (Information technology — 8-bit single-byte coded graphic character sets) characters (for statements of conformity issued in Bulgarian language in Cyril characters, for statements of conformity issued in Greek language in Greek characters) and Arabic numerals.

2. Features for protecting the statement of conformity

In accordance with Article 31(5) of Regulation (EU) 2016/1628, the statement of conformity shall be made in such a way as to prevent any forgery and allowing verification of the secure electronic file.

The paper used for the statement of conformity shall be protected by a watermark in the form of the registered mark of the manufacturer and by coloured graphics.

2.1.1. As an alternative to the requirements set out in point 2.1, the paper of the statement of conformity may be not protected by a watermark in the form of the registered mark of the manufacturer. In this case, the coloured graphics shall be supplemented with at least one additional security printing feature (e.g. ultraviolet fluorescent ink, inks with viewing angle-dependent colour, inks with temperature-dependent colour, micro printing, guilloche printing, iridescent printing, laser engraving, custom holograms, variable laser images, optical variable images, physically embossed or engraved manufacturer's logo, etc.).

2.1.2. Manufacturers may provide the statement of conformity with security printing features additional to those set out in points 2.1 and 2.1.1.

2.1.3. Where the statement of conformity has more than one sheet, each sheet shall state:

The electronic file shall be supplied in a format so that each modification after signing can be easily identified, and it can be incorporated into another document. In addition, it shall be signed by an ‘advanced electronic signature’ according to Regulation (EU) No 910/2014 of the European Parliament and of the Council (¹⁰), including the signature verification data.
