Plastics - Thermoplastic silage films and tubes for use in agriculture

This document specifies the requirements related to dimensional, mechanical, and optical characteristics of thermoplastic films and tubes used during the manufacture of silage and designed to last at least one year for protecting fodder.
It specifies a classification for the durability of silage films and the test methods referred to in this document.
This document is applicable to transparent, black, white or coloured (e.g. black/white) thermoplastic silage films based on polyethylene, ethylene copolymer, EVOH and polyamide.
These films are intended for covering bunker silos, silage tubes or silage clamps for preserving forage. They protect the forage and preserve it from rain and air. These films are not intended to cover bales piles (e.g. straw bales and hay bales).
Silage films obtained by sealing two or more films in machine direction are out of the scope of this document.
This document also defines installation, use and removal conditions of silage films. It defines the conventional useful lifetime, as well as rules that allow evaluating the remaining use potential in the event of a failure before the normal end-of-use date.
NOTE   These rules allow estimating the residual value of the films. These provisions only apply to the film itself and the damage it has undergone. Any other problem falls within the scope of professional practices and the general terms and conditions of sale.

Kunststoffe - Thermoplastische Silofolien und -schläuche für den Einsatz in der Landwirtschaft

Dieses Dokument legt die Anforderungen in Bezug auf die Maßeigenschaften sowie die mechanischen und optischen Merkmale thermoplastischer Folien und Schläuche fest, die bei der Erzeugung von Silage benutzt werden und für die eine Lebensdauer von mindestens einem Jahr als Schutz für Futtermittel vorgesehen ist.
Es legt eine Klassifikation bezüglich der Beständigkeit der Silofolien und der in diesem Dokument in Bezug genommenen Prüfverfahren fest.
Dieses Dokument gilt für transparente, schwarze, weiße oder farbige (z. B schwarz-weiße) thermoplastische Silofolien auf der Grundlage von Polyethylen, Ethylen-Copolymer, EVOH und Polyamid.
Diese Folien dienen der Abdeckung von Bunkersilos, Siloschläuchen oder Fahrsilos zum Schutz von Futtermitteln. Durch sie sind die Futtermittel regen- und luftgeschützt. Diese Folien dienen nicht der Abdeckung von Ballen (z. B. Strohballen und Heuballen).
Dieses Dokument gilt nicht für Silofolien, die mittels Versiegelung von zwei oder mehr Folien in Längs-richtung hergestellt werden.
Dieses Dokument legt ferner Bedingungen für das Anbringen, die Verwendung und das Entfernen der Silofolien fest. Es legt die übliche Nutzungsdauer sowie Regeln fest, die eine Bewertung des verbleibenden Nutzungspotentials im Falle eines Versagens vor Ablauf der üblichen Nutzungsdauer ermöglichen.
ANMERKUNG   Durch diese Regeln kann der Restwert der Folien geschätzt werden. Diese Bestimmungen gelten nur für die Folie selbst und den an ihr entstandenen Schaden. Andere Probleme fallen in den Anwendungsbereich beruflicher Praktiken und der allgemeinen Verkaufsbedingungen.

Plastiques - Films d'ensilage thermoplastiques et gaines pour utilisation en agriculture

Le présent document spécifie les exigences relatives aux caractéristiques dimensionnelles, mécaniques et optiques des films thermoplastiques et des gaines utilisés pour l’ensilage et conçus pour protéger le fourrage pendant une durée d’au moins une année.
Il spécifie une classification pour la durabilité des films d’ensilage et les méthodes d’essai auxquelles il est fait référence dans le présent document.
Le présent document est applicable aux films d’ensilage thermoplastiques transparents, noirs, blancs ou colorés (par exemple noirs/blancs) à base de polyéthylène, de copolymères d’éthylène, d’EVOH et de polyamide.
Ces films sont destinés à la couverture de silos couloirs, de gaines pour silos ou de pinces à ensilage en vue de la conservation du fourrage. Ils assurent la protection du fourrage ainsi que l’étanchéité à la pluie et à l’air. Ces films ne sont pas destinés à couvrir des piles de balles (par exemple des balles de paille et des balles de foin).
Les films d’ensilage obtenus en scellant ou soudant au moins deux bandes de films dans le sens machine sont en dehors du domaine d’application de ce document.
Le présent document définit également les conditions de mise en œuvre, d’utilisation et de dépose des films d’ensilage. Il définit la durée de vie utile conventionnelle, ainsi que les règles qui permettent l’évaluation du potentiel d’utilisation restant en cas de défaut avant la date normale de fin de vie.
NOTE   Ces règles permettent d’estimer la valeur résiduelle des films. Ces dispositions ne s’appliquent qu’au film lui-même et aux dégâts qu’il a subis. Tout autre problème tombe dans le domaine d’application des pratiques professionnelles et des conditions générales de vente.
