Plastics - Methods of exposure to laboratory light sources - Part 1 : general guidance

ISO 4892-1:2016 provides information and general guidance relevant to the selection and operation of the methods of exposure described in detail in subsequent parts. It also describes general performance requirements for devices used for exposing plastics to laboratory light sources. Information regarding performance requirements is for producers of artificial accelerated weathering or artificial accelerated irradiation devices. NOTE In this part of ISO 4892, the term "light source" refers to radiation sources that emit UV radiation, visible radiation, infrared radiation or any combination of these types of radiation. ISO 4892-1:2016 also provides information on the interpretation of data from artificial accelerated weathering or artificial accelerated irradiation exposures. More specific information about methods for determining the change in the properties of plastics after exposure and reporting these results is given in ISO 4582.

Plastics - Methods of exposure to laboratory light sources - Part 1 : general guidance

<p> La présente partie de l'ISO 4892 fournit des informations et un guide général pour la sélection et l'application des méthodes d'exposition décrites en détail dans les autres parties de la norme. Elle décrit également et recommande des méthodes pour la détermination de l'éclairement énergétique et de l'exposition énergétique. Les prescriptions relatives aux dispositifs utilisés pour contrôler la température de l'air à l'intérieur de l'enceinte et la température de surface des matériaux sombres et clairs sont également décrites. Elle fournit également des informations sur l'interprétation des données issues des essais d'exposition accélérée. Des informations plus spécifiques sur les méthodes de détermination des changements de propriétés des plastiques après exposition et de notification des résultats sont décrites dans l'ISO 4582. </p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
