Plastics - Method for artificial accelerated photoageing using medium pressure mercury vapour lamps

This European Standard specifies a method for carrying out artificial accelerated photoageing of test specimens by exposing them to medium pressure filtered mercury vapour lamp as light source, under controlled temperature conditions.

Kunststoffe - Verfahren zur künstlich beschleunigten Alterung bei Verwendung von Quecksilberdampflampen

Diese Europäische Norm legt ein Verfahren zur künstlich beschleunigten Alterung von Probekörpern durch deren Aussetzen einer gefilterten Strahlung der Mitteldruck-Quecksilberdampfstrahler als Strahlungsquelle bei geregelten Temperaturbedingungen fest.

Plastiques - Méthode de photovieillissement artificiel accéléré utilisant des lampes à vapeur de mercure à moyenne pression

La présente Norme européenne spécifie une méthode permettant de soumettre des éprouvettes à un photovieillissement artificiel accéléré en les exposant à une lampe à vapeur de mercure à moyenne pression filtrée en tant que source lumineuse, dans des conditions de température contrôlées.

Key X wavelength, nm Y spectral irradiance, mW·m-2·nm-1 Figure 1 — Typical spectrum of a filtered medium pressure mercury vapour lamp The filtered light emitted by a medium pressure mercury-arc does not simulate full spectrum sunlight but can be used to investigate photochemical phenomena. The relevancy to outdoor data shall be carefully considered. The only requirement is a relevant control of the chemical change in the solid state under polychromatic light. Additional optical filters may be used for specific applications. Annex A provides information on additional filtering of lamp UV radiations. Ensure the lamp has been pre-aged for 100 h prior to use, since the transmittance spectrum of borosilicate bulb may change significantly during this initial period. NOTE Commonly, the light output (intensity and wavelength) does not vary more than 20 % during the lifetime of the lamps (see 5.4 or 8.1). 5.1.2 Spectral irradiance of medium pressure mercury vapour lamps The minimum and maximum levels of the relative spectral irradiance in the UV region are given in Table 1.
