The standard EN 15651 is a series of standads that specifies definitions and requirements for sealants for non-structural use in joints in buildings and pedestrian walkways. The separate parts of the standard (part 1- 4) contain the different applications of sealants with the corresponding test specifications. Part 5 includes the description for evaluation of conformity and marking of individual products. 

This standards series specifies definitions and requirements for cold applied non-structural elastic sealants used for movement joints in floors in building construction for interior and exterior use, e.g. for pedestrian walkways and public areas. The contents of the standard parts of EN 15651-1 to -4 are specified below.

Part 5 comprises the determinations for evaluation of conformity, thus the initial type testing of the product as well as the corresponding necessary factory production control. The products have to be put to the corresponding initial type testing. On basis of the initial type testing, the classification will be determined if the result is positive and a classification report will be issued. If the standard-compliant factory production control is present, the products can be marked according to the specifications of EN 15651-5.
