標準 EN 12245:2002 は、運搬可能なガスシリンダーに関するもので、特に完全にラップされた複合シリンダーに焦点を当てています。この標準は、水容量450リットルまでの圧縮、液化、溶解ガス用の複合ガスシリンダーについて、材料、設計、構造、プロトタイプテストおよび定期的な製造検査の最低要件を規定しています。 この標準の強みは、複合シリンダーの安全性と性能を確保するための具体的かつ詳細な要件を示している点にあります。金属材料（溶接または無縫製）または非金属材料のライナーと、ガラス、カーボン、アラミドなどの繊維で構成されたラップ複合材による強化を受けたシリンダーが含まれています。また、ライナーなしの複合シリンダーにも適用されるため、さまざまな設計ニーズに応じた柔軟性があります。 この標準の関連性は、特に運搬可能なガスシリンダーの安全性向上において極めて重要です。市場での需要や技術革新に応じて、改良された材料や設計方法を反映した規格として、業界関係者にとって重要な指針となります。 ただし、本標準はファイバーで部分的に覆われたシリンダー、通称「フープラップ」シリンダーには適用されず、これに関する詳細は別の標準である EN 12257 に基づく必要があります。この点も十分に考慮するべき事項として明記されています。 このように、EN 12245:2002 は、複合ガスシリンダーの設計と製造における重要な基準を提供し、安全性の確保と技術基準の維持に寄与する、極めて価値のある標準と言えるでしょう。
The EN 12245:2002 standard plays a crucial role in the regulation and safety of transportable gas cylinders, specifically focusing on fully wrapped composite cylinders. Its scope is comprehensive, specifying the minimum requirements for materials, design, construction, prototype testing, and routine manufacturing inspections for composite gas cylinders with a water capacity up to and including 450 liters. This wide-ranging applicability ensures that various types of gases-compressed, liquefied, and dissolved-can be safely stored and transported, making it highly relevant for both manufacturers and end-users in the gas industry. One of the strengths of EN 12245:2002 is its clear definition of what constitutes a composite gas cylinder. By including cylinders with both metallic and non-metallic liners, it addresses a significant range of manufacturing techniques and materials. The inclusion of wound composites utilizing glass, carbon, or aramid fibers embedded in a matrix reflects the standard's adaptability to emerging technologies in composite materials while enforcing safety measures through rigorous testing and inspection protocols. The differentiation between fully wrapped composite cylinders and "hoop wrapped" cylinders is another noteworthy strength. By explicitly stating that the standard does not apply to partially fiber-covered cylinders, it clarifies the specific context of application for manufacturers, allowing for a more straightforward compliance process. Despite its focused scope, the standard does have limitations regarding removable protective sleeves, indicating that although protective sleeves may be relevant, they should not be conflated with the core regulations outlined within EN 12245:2002. This delineation helps prevent confusion while upholding safety and performance standards. Overall, the EN 12245:2002 standard is a vital document for ensuring the safe handling and performance of composite gas cylinders, solidifying its position as an essential reference for manufacturers and industry stakeholders involved in the production and use of these critical safety devices. Its robust nature and clarity in requirements make it particularly valuable in fostering safe practices within the gas cylinder transport sector.
SIST EN 12245:2002 표준은 운송 가능한 가스 실린더의 최소 요구 사항을 규정하는 유럽 표준으로, 압축, 액화 및 용해된 가스를 위한 450리터 이하의 수용력을 가진 복합 가스 실린더의 소재, 설계, 제작, 프로토타입 테스트 및 일상적인 제조 검사를 포함합니다. 이 표준의 사용 범위는 금속 재료(용접 또는 무용접) 또는 비금속 재료(또는 이의 혼합물)로 구성된 실린더에 적용되며, 유리, 탄소 또는 아라미드 섬유로 구성된 감싸기 복합체에 의해 보강됩니다. SIST EN 12245:2002의 강점은 안전성과 신뢰성을 강조하며, 다양한 가스 용기에 적용할 수 있는 포괄적인 기준을 제공한다는 점입니다. 특히 이 표준은 실린더가 라이너가 없거나 라이너가 포함된 경우 모두에 적용 가능하여 다양한 응용 분야를 수용할 수 있습니다. 그러나 부분적으로 섬유로 덮인 실린더(일명 "후프 랩" 실린더)에 대해서는 적용되지 않으며, 이러한 유형의 실린더에 대해서는 EN 12257을 참고해야 합니다. 이 표준의 중요성은 복합 재료를 사용한 실린더의 신뢰성을 높이는 데 기여하며, 사용자의 안전을 보장하는 동시에 환경적 요구 사항을 충족하는 고성능 가스 실린더를 개발하는 데 필수적입니다. 따라서 SIST EN 12245:2002는 관련 산업에서 매우 중요한 참조 문서이며, 가스 저장 및 운송 과정의 안전성을 높이는 역할을 합니다.
