Measurement procedures for materials used in photovoltaic modules - Part 1 -4 : Encapsulants - Measurement of optical transmittance and calculation of the solar-weighted photon transmittance, yellowness index, and UV cut-off wavelength

Le présent document fournit une méthode de mesure du facteur de transmission optique des matériaux d'encapsulation utilisés dans les modules photovoltaïques (PV) . Les mesurages normalisés de cette procédure permettent de quantifier le facteur de transmission prévu de l'encapsulation vers la cellule PV. Le calcul ultérieur du facteur de transmission à pondération solaire permet de comparer les différents matériaux. Cette méthode de mesure peut également être utilisée pour contrôler les performances des matériaux d'encapsulation après exposition aux intempéries, afin d'évaluer leur durabilité. dow : 2019-11-01

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.

With Requirements, quickly access the main part of the normative text!
