1 Field of application 1 T ill?mpn i ng

This method covers determination of the fogging characteristics of organic materials.

If no method has been indicated in the document re- ferring to this standard, method F is implied. Denna metod avser att best?mma organiska materials foggingegenskaper.

Om ingen metod anges p? det dokument som

h?nvisar till denna standard ?r det metod F som avses.

2 Definition 2 Defi ni ti on

By fogging is meant the tendency of an interior trim material to emit, under the influence of heat, sub- stances forming depositions primarily on windscreens and rear windows. This can lead to reduced visibility. Method F: The fogging value F is the ratio, expressed in per cent, of gloss before and after the fogging test. The gloss is measured with a glossmeter with a 60°measuring angle. Med fogging menas ett inredningsmaterials tendens att i v?rme avge ?mnen som vid kondensation p?framf?rallt vindruta och bakruta bildar bel?ggningar, som kan f?rs?mra sikten.

Metod F: Foggingv?rdet F ?r kvoten i procent mellan glans f?re och efter foggingprovet. Glansen m?ts med en glansm?tare med 60° m?tvinkel.

Method G: The fogging value G is the mass of the condensation on the aluminium foil, i.e. it is the difference, expressed in mg, between the aluminium foil before and after testing. Metod G: Foggingv?rdet G ?r massan av det som kondenserar p? aluminiumfolien, d.v.s. det ?r skillnaden i mg p? aluminiumfolien f?re och efter provning.

6.1.4.2 Measuring gloss

6.1.4.2 M?tning av g l an s

The gloss of the glass plates is determined by measuring five points R 01-05 before fogging in accordance with the glossmeter instructions.

Place the plate in the fixture with the non-tin surface upwards, and focus the measurement on a point in the centre. The other points to be measured shall be situated 25 mm ± 5 mm from the centre. Measuring shall be done against a white background. Appropriate is, e.g., a white filter paper.

The measuring shall be carried out in such a way that it is ensured that the same point is measured before and after fogging, i.e. R 01=R 11.

After the fogging test, the measuring is repeated in the same way, i.e. R 11-15. The mean value of these values is the fogging which is emitted during the test.

If the gloss readings, Fj, for the test pieces (glass plates) deviate more than ± 5 % units from the mean value and none of the test pieces is approved, test a further two glass plates and calculate the mean value of the results obtained for all test pieces.

Vid best?mmning av glansen p? glasplattorna m?ts detta p? fem punkter R 01-05 f?re fogging enligt instruktionen till glansm?taren.

L?gg plattan i fixturen med icke-tennsidan upp?t och utf?r m?tningen p? en punkt i mitten. De ?vriga

punkterna som m?ts skall ligga 25 mm ± 5 mm fr?n mitten. M?tningen skall ske mot vit bakgrund. L?mplig bakgrund ?r t.ex. ett vitt filterpapper.

M?tningen skall utf?ras p? ett s?dant s?tt det s?kerst?lls att samma punkt m?tes f?re och efter fogging d.v.s. R 01 = R 11.

Efter foggingprovningen upprepas m?tningen p? samma s?tt d.v.s. R 11-15. Medelv?rdet av dessa

v?rden ?r den fogging som avges under provets g?ng.

Om glansv?rdena, Fj, f?r provkropparna (glas-

plattorna) avviker mer ?n ± 5 % enheter fr?n medel- v?rdet och ingen av provkropparna ?r godk?nd, provas ytterligare tv? provkroppar och medelv?rdet baserat p? alla provkropparna ber?knas.

6.1.4.3 Calculating fogging value F

6.1.4.3 Ber?kning av foggingv?rde F

To calculate F in %, the fogging value F j is first

calculated for each glass plate by using the following equation:

F?r att r?kna ut F i %, ber?knas f?rst foggingv?rdet F j f?r varje glasplatta med denna formel:

The post-test weighing shall be carried out after that the aluminium foil has been dried in a dessicator with silica gel. Lint-free cotton gloves or polythene gloves shall be used during weighing to avoid contamination.

Carry out measurements on minimum two test pieces. If the mass, Gj, of the condensable constituents deviate by more than 0,2 mg or 10 % from the mean value and none of the test pieces is approved, test a further two test pieces and calculate the mean of the results obtained for all test pieces. Aluminiumfolien v?gs f?re och efter provet med en noggrannhet av ± 0,01 mg. V?gningen efter provet skall ske efter att aluminiumfolien har torkas i en exsickator med silikagel. Vid v?gningen skall luddfria bomullshandskar eller polyetenhandskar anv?ndas f?r att undvika nedsmutsning.

Notera m?tv?rderna fr?n minst tv? provkroppar. Om massan, Gj, f?r de kondenserade ?mnena avviker mer ?n 0,2 mg eller 10 % fr?n medelv?rdet och ingen av provkropparna ?r godk?nd provas ytterligare tv?provkroppar och medelv?rdet baserat p? alla provkropparna ber?knas.

6.2.4.3 Calculating the fogging value G 6.2.4.3 Ber?kning av foggingv?rdet G

To calculate G in mg, the value of G j is calculated for each glass plate by using: F?r att r?kna ut G i mg, r?knas v?rdet G j ut f?r varje glasplatta genom att anv?nda:

G j = G1 – G0 G j = G1 – G0

where d?r

G j is fogging on each piece of aluminium foil G j ?r fogging p? varje bit aluminiumfolie

G1 is the mass of the aluminium foil after the test, in mg G1 ?r massan av aluminiumfolien efter provning, i

mg

G0 is the mass of the aluminium foil before the test, in mg. G0 ?r massan av aluminiumfolien f?re provning, i mg.

The fogging value G is the mean value of G j .

G is reported with an accuracy of 0,01 mg. Foggingv?rdet G ?r medelv?rdet av G j.

G redovisas med en noggrannhet av 0,01 mg.
