BS EN 13207:2018规定了与尺寸、机械和光学相关的要求 青贮饲料生产过程中使用的热塑性薄膜和管的特性 保护饲料至少一年。本标准规定了青贮薄膜耐久性的分类以及本标准中提及的试验方法 标准本欧洲标准适用于透明、黑色、白色或彩色（如黑色/白色） 基于聚乙烯、乙烯共聚物、EVOH和聚酰胺的热塑性青贮薄膜。这些薄膜用于覆盖料仓筒仓、青贮管或青贮夹，以保存饲料。它们保护牧草，防止雨水和空气进入。这些贴膜不适用于包裹 堆（例如稻草捆和干草捆）。通过在机器方向上密封两个或两个以上薄膜获得的青贮薄膜不在本标准范围内 文件本欧洲标准还规定了青贮薄膜的安装、使用和移除条件。它定义了 常规使用寿命，以及允许评估未来剩余使用潜力的规则 在正常使用结束日期之前发生故障的事件。交叉引用:ISO 4892-2ISO 527-1EN ISO 4892-2ISO 4592EN ISO 7765-1EN ISO 527-1ISO 4593ISO 7765-1EN ISO 527-3（ISO 527-3:1995 AS）EN ISO 4892-3EN 15347ISO 15270EN ISO 4892-1EN 15344EN 16472EN 15343ISO 4892-1ISO 4892-3ISO 9370:2017ISO/TR 19032:2006 Ed 1ISO 10640:2011 Ed 1购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS EN 13207:2018 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 standard.This European Standard 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 European Standard 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.Cross References:ISO 4892-2ISO 527-1EN ISO 4892-2ISO 4592EN ISO 7765-1EN ISO 527-1ISO 4593ISO 7765-1EN ISO 527-3 (ISO 527-3:1995 AS)EN ISO 4892-3EN 15347ISO 15270EN ISO 4892-1EN 15344EN 16472EN 15343ISO 4892-1ISO 4892-3ISO 9370:2017ISO/TR 19032:2006 Ed 1ISO 10640:2011 Ed 1All current amendments available at time of purchase are included with the purchase of this document.
