CEN/TC 129/WG 6 - Coated glass for windows

This European Standard covers the evaluation of conformity and the factory production control of coated glass for use in buildings.
NOTE   For glass products with electrical wiring or connections for, e.g. alarm or heating purposes, other directives, e.g. Low Voltage Directive, may apply.

This European Standard defines a test method to establish the self-cleaning performances for coatings on glass which utilize sun, rain or a combination of sun and rain to enhance the cleanliness of the glass.
The European Standard applies to class A coated glass as defined in EN 1096 1 and EN 1096 2 for use in outdoor building applications. The test is designed to be applicable for coatings on glass which use hydrophilic or photocatalytic active functionalities to enhance the cleanliness of the glass.
The test procedure does not specifically address the durability of the coating's self-cleaning functionality.

This European Standard defines the characteristics, properties and classification of coated glass for use in building.
Test methods and procedures used to establish durability are in Parts 2 and 3 of this standard.
Factory production control and evaluation of conformity, including Annex ZA, are in Part 4 of this standard.
Test methods for determination of self cleaning performances of coated glass are in Part 5.
This standard applies to coated glass for glazing application for use in normally occupied domestic or commercial premises.
This standard is not applicable to:
   adhesive backed polymeric films on glass (prEN 15755-1);
   mirrors made from silvered float glass (EN 1036-1);
   enamelled glass (EN 12150-1).

This European Standard specifies requirements and test methods related to artificial weathering and abrasion of coatings on glass for use in buildings.
These tests are aimed at evaluating the resistance of the coating to attack by simulated natural weathering conditions as well as to abrasion. This attack can be considered as representative of that which could be found on the external and/or internal face of the glazing.
This European Standard applies to Class A, B and S coatings, as described in EN 1096-1.

This European Standard specifies requirements and a test method related to resistance to solar radiation for coated glass for use in buildings.
This test is aimed at evaluating if the exposure to solar radiation over an extended period of time produces any appreciable change in light transmittance and solar transmittance of the coated glass as well as a reduction of the infrared reflectance in the case of low emissivity coatings.
This European Standard applies to Class C and D coatings as defined in EN 1096-1 and used in insulating glass units.

This draft defines a test method to establish the self-cleaning performances and classes for coatings on glass
which utilise sun, rain or a combination of sun and rain to enhance the cleanliness of the glass.
The draft applies to coated glass for use in outdoor building applications. The test is designed to be applicable
for coatings on glass which use hydrophilic or photocatalytic active functionalities to enhance the cleanliness
of the glass.
The test procedure does not specifically address the durability of the coatings self cleaning functionality.
The test method is designed to be run on monolithic samples of the products. In cases where dual coated
products (that is, a glass presenting self cleaning coating on one side and another coating on the other side)
exist it would be necessary to obtain the equivalent glass with only the self cleaning coating on one side (or to
remove the back side coating by polishing, providing it does not damage the self cleaning coating on the
opposite side). If not possible, adapted protection of back side coating should be added (such as protective
film with electrostatic or low adhesive charge,or DGU assembly)
For tinted glass and absorbing layers (a self cleaning or dual coatings) the luminous absorption might affect
the haze measurements. The test has to be runned on clear glass and extrapolation will be made for tinted
glass and absorbing layers.
