Une fiche de données de sécurité conforme à l’ISO 11014-1 doit être disponible pour les produits fabriqués et livrés conformément à la présente norme
Prepreg materials, available in rolls, sheets, and cut panels, must be packaged and sealed to ensure adequate protection against deterioration and physical damage during transportation and storage.
Unless otherwise specified in the purchase order, pre-impregnated materials must be labeled on the smallest packaging with the manufacturer's name, lot number, and manufacturing date.
Shipping packaging must have a label that remains securely attached and legible during normal handling The label's placement and type of marking should follow the specifications outlined in the diagram or purchase order; if not specified, they should adhere to the supplier's standard marking and labeling practices The label must include the following information: a) type of material; b) manufacturer's designation; c) lot number; d) edition quantity; e) dimensions; f) gross weight; g) manufacturing date; h) names and address of the manufacturer; i) packaging date.
Les matériaux préimprégnés doivent pouvoir être stockés selon une des conditions ci- dessous pendant une durée spécifiée et rester en état pour leur utilisation prévue
Condition 1: Température ≤5 °C, humidité relative non spécifiée, minimum 6 mois après fabrication
Condition 2: Température ≤20 °C, humidité relative ≤50 %, minimum 3 mois après fabrication
It is essential to avoid storing pre-impregnated materials in catalytic environments, such as excessive UV light or radiation Additionally, materials that have been stored at lower temperatures should be allowed to return to room temperature before opening to prevent moisture condensation on the pre-impregnated material itself.
