(Main)Plastics - Determination of the total luminous transmittance of transparent materials - Part 2: Double-beam instrument (ISO 13468-2:1999)
Plastics - Determination of the total luminous transmittance of transparent materials - Part 2: Double-beam instrument (ISO 13468-2:1999)
This part of ISO 13468 covers the determination of the total luminous transmittance, in the visible region of the
spectrum, of planar transparent and substantially colourless plastics, using a double-beam scanning spectrophotometer.
This part of ISO 13468 cannot be used for plastics which contain fluorescent materials.
This part of ISO 13468 is applicable to transparent moulding materials, films and sheets not exceeding 10 mm in
thickness.
NOTE 1 Total luminous transmittance can also be determined by a single-beam instrument as in part 1 of this International
Standard.
NOTE 2 Substantially colourless plastics include those which are faintly tinted.
NOTE 3 Specimens more than 10 mm thick may be measured provided the instrument can accommodate them, but the
results may not be comparable with those obtained using specimens less than 10 mm thick.
Kunststoffe - Bestimmung des totalen Lichttransmissionsgrades von transparenten Materialien - Teil 2: Zweistrahlinstrument (ISO 13468-2:1999)
Anwendungsbereich
Dieser Teil von ISO 13468 behandelt die Bestimmung des totalen Lichttransmissionsgrades von ebenen, transparenten und im Wesentlichen farblosen Kunststoffen im sichtbaren Spektralbereich mit einem abtastenden Zweistrahlspektralfotometer. Dieser Teil von ISO 13468 kann nicht auf Kunststoffe mit fluoreszierenden Bestandteilen angewendet werden.
Dieser Teil von ISO 13468 gilt für transparente Formmassen, Folien und Tafeln mit einer Dicke bis einschließlich 10 mm.
ANMERKUNG 1 Der totale Lichttransmissionsgrad kann auch mit einem Einstrahlinstrument wie in Teil 1 dieser Internationalen Norm bestimmt werden.
ANMERKUNG 2 Zu den im Wesentlichen farblosen Kunststoffen gehören die schwach eingefärbten.
ANMERKUNG 3 Probekörper dicker als 10 mm dürfen gemessen werden, vorausgesetzt, das Instrument kann sie aufnehmen, jedoch können die Ergebnisse mit denen, die mit Probekörpern einer Dicke bis zu 10 mm erhalten wurden, nicht vergleichbar sein.
Plastiques - Détermination du facteur de transmission du flux lumineux total des matériaux transparents - Partie 2: Instrument à double faisceau (ISO 13468-2:1999)
La présente partie de l'ISO 13468 traite de la détermination du facteur de transmission lumineuse totale dans le
domaine visible des plastiques plans, transparents et pratiquement incolores, au moyen d'un spectrophotomètre à
double faisceau. Elle ne peut pas être appliquée aux plastiques contenant des matériaux fluorescents.
La présente partie de l'ISO 13468 est applicable aux matériaux pour moulage ainsi qu'aux feuilles minces, feuilles
continues et films d'épaisseur inférieure ou égale à 10 mm.
NOTE 1 Le facteur de transmission lumineuse totale peut également être déterminé au moyen d'un instrument à faisceau
unique, comme dans l'ISO 13468-1.
NOTE 2 Dans les plastiques pratiquement incolores sont également inclus les plastiques légèrement colorés.
NOTE 3 Les éprouvettes de plus de 10 mm d'épaisseur peuvent être soumises au mesurage si la structure de l'appareillage
utilisé le permet, mais les résultats ne sont pas comparables à ceux que l'on obtient sur des éprouvettes de moins de 10 mm.
