Hi
Below is the link to obtain the list of applicable harmonized standards for IVD products.
http://eur-lex.europa.eu/LexUriServ/...31:0034:EN:PDF
Related to labeling, apart from EN 980, EN 18113, ISO 15223 is also a good source to refer.
For "graphics on interface" what exactly you are referring? Just on the flash screen to show it as an IVD? If so, IVD symbol is sufficient.
