Overview
EN 1096-5:2016 - published by CEN - specifies a laboratory test method and classification for the self‑cleaning performance of coated glass surfaces used outdoors. It applies to class A coated glass (see EN 1096-1 / EN 1096-2) and covers coatings that rely on hydrophilic or photocatalytic functionalities to use sun, rain, or a combination of both to keep glass cleaner than untreated substrate. The procedure quantifies change in transmission haze after a controlled sequence of dirt deposition, UV‑A exposure and water spray. Note: durability of the self‑cleaning function is not addressed by this part.
Key topics and technical requirements
- Scope: Test method for self‑cleaning coatings on class A coated glass for outdoor building use.
- Test principle: Standardized dirt spray → UV‑A irradiation (sun simulation) → deionized water spray (rain simulation); cycle repeated twice.
- Performance metric: Change in transmission haze (∆H = Hfinal − Hinitial). Haze is defined as the percentage of transmitted light deviating by more than 2.5°.
- Instrumentation: UVA illumination chamber, sample support and spray rig, spraying nozzle and timers, dirt and water pressure tanks, furnace for drying, haze measurement instrument.
- Sample handling: Pre‑cleaning and activation (UV) of samples, control samples, and contamination‑free environment requirements.
- Contamination control & repeatability: Normative annexes cover sample support, haze measurement methods, contamination checks, statistical analysis and round‑robin results to aid reproducibility.
- Classification & reporting: Criteria and statistical procedures for classifying self‑cleaning performance and required test report contents are specified.
Applications and users
EN 1096-5:2016 is practical for:
- Coated glass manufacturers developing hydrophilic or photocatalytic self‑cleaning products.
- Independent test laboratories performing standardized performance verification and classification.
- Specifiers, architects and façade engineers who need objective test data to select self‑cleaning glass for building envelopes.
- Glazing contractors and façade consultants comparing products or documenting compliance.
- Regulatory bodies and certification schemes requiring harmonized test evidence.

= Hfinal - Hinitial Haze variation between initial cleaning stage and end of cycle 2 5 Principle of the test Standardized glass samples shall be submitted to a spray of a standardized dirt mixture, followed by a simulation of natural weathering action by applying UV irradiation (to simulate sun) and water spray (to simulate rain). This cycle shall be repeated twice to ensure better stability of results. SIST EN 1096-5:2016
(1) NOTE The incident light on glass samples with dirt deposit is diffused scattered and the effect in transmission is seen as reduction of contrast of objects observed through the glass. It is strongly recommended to measure haze at each step of the test (as explained in Clause 10) in order to check that there is no deviation of the test. The test and all handling of the product to be tested shall be performed in a clean environment, i.e. exempt from any source of contamination (organics, silicones, dust) which could modify the surface, affect the functionality, the test conditions or the haze measurements. An example of contamination checking procedure is given in Annex C. 6 Instrumentation 6.1 UVA-Illumination chamber A UV illumination chamber1) shall be equipped with UVA-340 lamps, such as described in EN ISO 4892-3:2013, Table 1 (“type I” lamps). A closed chamber is recommended. The irradiation power shall be set to 0,68 W·m «2·nm «1 at 340 nm on the surface of the samples, which is the maximal irradiance of solar light according to CIE 85 Table 4. The irradiation level shall be maintained constant and uniformly distributed such as to ensure a same level of irradiation on all the samples. NOTE
The irradiation level can be monitored with a radiometer. The intensity of the lamp can be controlled continuously and adjusted to balance aging of the lamps. Relative Humidity (RH) shall be maintained between 15 % and 50 % inside the chamber during the irradiation period. The air temperature in the illumination chamber shall remain between 25°C and 40°C. The UVA cabinet shall be placed in a well-ventilated area and its vents shall be fully opened, to ensure that the temperature inside the cabinet remains in the indicated values. The temperature and RH shall be monitored and given in the test report. The cabinet shall be clean and exempt of any contamination source, especially silicone source, see Annex C. 6.2 Sample support For the spraying steps, the sample shall be installed on a support, with an inclination of 10° from vertical. The description of the support is given in Annex A.

NOTE 2 For tinted glass and absorbing layers (self-cleaning or dual coatings) the light absorption may affect the precision of haze measurements. 7.2 Tested sample A minimum of 6 samples shall be tested for a given self-cleaning coating. The chosen number of samples shall be indicated as “n”. In case the product to be tested has to be toughened to become active, the test shall be performed on toughened samples. In case the product can be used annealed or toughened, both types shall be tested, with a minimum of 6 annealed samples and 6 toughened samples. The size of the samples shall be 150 mm x 300 mm. The central zone shall be analysed and the sample shall be positioned vertically, as described in Figure 1. The sample shall be engraved with references on the upper left corner of the opposite side from the side to be tested i.e. non coated side. SIST EN 1096-5:2016
Key 1 sample 2 test zone on the sample Figure 1 — Description of test sample 7.3 Control sample A minimum of 6 control samples shall be tested along with the self-cleaning products to be tested. Control samples shall have a behaviour known in advance. A commercial product can be used. The use of clear float glass as control sample should be avoided, due to the sensibility of its surface to its history. Control samples shall fulfil these criteria: — stability of performances and homogeneity; — availability; — low visible absorption; — low initial haze. EXAMPLE Examples of references samples are: — silica sheets; — float glass coated with a given oxide layer, resistant to corrosion (such as silica or photocatalytic coating); — commercially available photocatalytic self-cleaning glass. If control samples do not give the expected results a new test shall be performed, ensuring that all test conditions are respected. SIST EN 1096-5:2016
