NOTE 1 Wavelengths in the atmosp eric win ow b low 2 0 nm are not covered by this part of ISO 9 2

However,wavelengths b low 2 0 nm can inc e se long -t erm de radation of optic , surfaces an other materials

In outdo r con itions, material de radation can therefore oc ur even when pas ing the test ac ording t o this

part of ISO 9 2

radiation incident u on a horizontal are of the e rth surface an is, with the su b ing at he zenith, composed

of direct solar radiation an solar radiation difusely reflected from the atmosp ere T e glo al radiation is not

constant an has therefore b en determined by the International Commis ion on Ilumination (CIE) on the b sis

used to determine thermal, p ot omechanical an a eing influences De re s of severity 0 an 04 do not
