5.3 HYGIENE, HEALTH AND THE ENVIRONMENT5.3.1 Air and/or water permeabilityNot relevant5.3.2 Release of dangerous substancesRegarding the release/content of dangerous substances the ETA-applicant shall declare thatno substances as specified in EC-database are used for the production of his reactive coatingsystem.5.4 SAFETY IN USE5.4.1 Mechanical resistance and stabilityNot relevant5.4.2 Resistance to impact/movementNot relevant5.4.3 AdhesionNo specific verification method (but see 5.7.1 Serviceability)5.5 PROTECTION AGAINST NOISENo specific verification method.5.6 ENERGY ECONOMY AND HEAT RETENTIONNo specific verification method.5.7 ASPECTS OF SERVICEABILITY, DURABILITY AND IDENTIFICATION5.7.1 Serviceability5.7.1.1 AdhesionNo specific verification method.Adhesion of the reactive coating system (primer, reactive coating layer with/without top coat) tothe substrate (and cohesion of the system) is covered by testing the insulation efficiency (see5.7.2.2.1).5.7.2 Durability5.7.2.1 Corrosion resistanceThe tests under 5.7.2.2 will serve to indicate whether the coating has an adverse effect on theprimer and/or substrate and whether the reactive coating system provide corrosion protectionto the substrate. The durability testing shall be carried out with the same reactive coatingsystem used for the fire resistance tests.5.7.2.2 Behaviour under different environmental conditions
