Aluminium may only be used for the shells of portable tanks when indicated in a portable tank special provision assigned to a specific substance in Column (11) of Table A of Chapter 3.2 RID/ADR or when approved by the competent authority. NOTE 1 For aluminium and aluminium alloys, see also EN 14286. SIST EN 14025:2013
9 NOTE 2 RID/ADR restrict the use of materials with respect to the maximum yield and tensile strength of fine-grained steel for welded shells, maximum ratios of yield/tensile strength for welded steel shells and of the minimum elongation at fracture for welded fine- grained other steel and aluminium shells. Welded shells shall be fabricated from a material which has been shown to have acceptable welding characteristics. 4.2 Compatibility Shells, fittings, and pipework shall be constructed from materials which are: a) substantially immune to attack by the substance(s) intended to be transported; or b) properly passivated or neutralised by chemical reaction; or c) lined with corrosion-resistant material directly bonded to the shell or attached by equivalent means.

In addition, the design of portable tanks shall account for the effects of fatigue, caused by repeated application of these loads through the expected life of the portable tank; 2) test conditions; 3) explosion pressure proof conditions (if required); under consideration of Clause 6. If sudden temperature differences are to be expected during filling or discharge of the tank the buckling effect of one sided expansion or contraction should be taken into account. 5.2 Minimum shell thickness The shell thickness shall not be less than that given in: RID/ADR 6.8.2.1.17 to 6.8.2.1.18, see Figure 1 of this standard RID/ADR 6.7.2.4 or 6.7.3.4, see Figure 2 of this standard SIST EN 14025:2013

この記事では、EN 14025:2013という欧州規格について話しています。この規格は、危険物を道路、鉄道、海上で輸送するための金属製圧力タンクの設計と建設に関する最小要件を定めています。開口部、閉鎖装置、構造装置などの領域をカバーしていますが、サービス装置の要件には触れていません。極低温液体を輸送するタンクには別の規格（EN 13530-1およびEN 13530-2）が適用されます。圧力タンクの設計と建設は、RID/ADRの要件に従う必要があり、特定のセクションと列が適用されます。携帯用タンクにはRID/ADRに基づく個別の要件があります。RID/ADRの要件は、この規格のどの節でも先にされる必要があります。一部の条項はすべてのタンクに適用され、他の条項は道路および鉄道圧力タンクまたは携帯用タンクにのみ適用されます。
이 기사는 유럽 표준 EN 14025:2013을 다루고 있습니다. 이 표준은 위험물을 도로, 철도 및 해상으로 운송하는 데 사용되는 금속 압력 탱크의 최소 요구 사항을 규정합니다. 열결, 폐쇄 및 구조 장비와 같은 영역을 다루지만 서비스 장비에 대한 요구 사항은 다루지 않습니다. 매우 저온 액체를 운송하는 탱크는 별도의 표준 (EN 13530-1 및 EN 13530-2)에 따릅니다. 압력 탱크의 설계와 건설은 RID/ADR의 요구 사항을 준수해야 하며, 특정 섹션 및 열에 해당됩니다. 휴대용 탱크는 RID/ADR에 따라 별도의 요구 사항이 있습니다. RID/ADR의 요구 사항이 이 표준보다 우선되야 함을 주의해야 합니다. 일부 조항은 모든 탱크에 해당하며, 다른 조항은 도로 및 철도 압력 탱크 또는 휴대용 탱크에만 해당합니다.
The article discusses the European Standard EN 14025:2013, which outlines the minimum requirements for the design and construction of metallic pressure tanks used for transporting dangerous goods by road, rail, and sea. The standard covers areas such as openings, closures, and structural equipment, but does not address service equipment. Tanks for transporting cryogenic liquids have separate standards (EN 13530-1 and EN 13530-2). The design and construction of pressure tanks must adhere to the requirements of RID/ADR, with specific sections and columns applicable. Portable tanks have their own specific requirements under RID/ADR. It's important to note that the requirements of RID/ADR take precedence over the standard. Certain provisions apply to all tanks, while others are specific to either road and rail pressure tanks or portable tanks.
This article discusses the requirements for the design and construction of metallic pressure tanks used for the transport of dangerous goods. The tanks must have a maximum working or test pressure exceeding 50 kPa (0.5 bar), and this standard applies to tanks used for road, rail, and sea transport. It specifies requirements for openings, closures, and structural equipment, but does not cover service equipment. Tanks for the transport of cryogenic liquids are subject to different standards (EN 13530-1 and EN 13530-2). The article mentions that the design and construction of these tanks must primarily meet the requirements of RID/ADR, with specific references to relevant sections and columns of the regulation. Portable tanks and their requirements are also mentioned. However, it is important to note that RID/ADR requirements take precedence over the European Standard. The article concludes by stating that provisions applying to the entire page are applicable to all kinds of tanks, while provisions in specific columns apply to road and rail pressure tanks and portable tanks according to RID/ADR.
この記事では、危険物輸送用の金属製圧力タンクの設計と構造に対する最低要件が示されています。最大の作業または試験圧力が50 kPa（0.5バール）を超えるタンクを対象としています。このヨーロッパ標準は、道路、鉄道、海上輸送に使用されるタンクに関する要件を規定しています。開口部、閉鎖装置、構造装置の要件を明示し、サービス装置の要件はカバーしていません。極低温液体輸送用のタンクには別の規格（EN 13530-1およびEN 13530-2）が適用されます。 RID/ADR 6.8.2.1、6.8.3.1、および6.8.5の要件に基づき、このヨーロッパ標準の範囲に応じた圧力タンクの設計と構造は、主にRID/ADRの要件を満たす必要があります。さらに、RID/ADRの関連要件には、3.2章の表Aの12列と13列、4.3、および6.8.2.4も適用されます。構造装置については、関連する箇所である6.8.2.2および6.8.3.2が適用されます。RID/ADR 1.2.1の定義を参照します。可搬式タンクについては、RIDおよびADRの4.2および6.7.2、6.7.3の節も言及されています。さらに、RID/ADRの関連要件は、3.2章の表Aの10列と11列、4.2、6.7.2、および6.7.3にも適用されます。 上記の段落番号は、定期的な改定が行われるRID/ADRの2013年版に関連しています。これにより、一時的にEN 14025との不一致が生じる可能性があります。RID/ADRの要件がこの規格のいかなる条項よりも優先されることを知ることが重要です。 それ以外の場合は、ページ全体を占める規定はすべての種類のタンクに適用されます。単一の列に含まれる規定は次の通りです：RID/ADRの6.8章に基づく道路および鉄道圧力タンク（左側の列）およびRID/ADRの6.7章に基づく可搬式タンク（右側の列）。

RID/ADR 6.8.2.1, 6.8.3.1 및 6.8.5 요구 사항에 따라 이 유럽 표준의 범위에 따른 압력탱크의 디자인과 구조는 주로 RID/ADR의 요구 사항을 충족시켜야 한다. 또한, RID/ADR의 관련 요구 사항은 Table A의 3.2장의 12번 및 13번 열, 4.3 및 6.8.2.4에도 적용된다. 구조적 장비에 대해서는 6.8.2.2 및 6.8.3.2 하위 항목에 필요한 사항이 적용된다. RID/ADR 1.2.1의 정의를 참조한다. 이동식 탱크에 대해서는 RID 및 ADR의 4.2장 및 6.7.2 항목 및 6.7.3 항목도 참고한다. 또한, RID/ADR의 관련 요구 사항은 3.2장의 Table A의 10번 및 11번 열, 4.2, 6.7.2 및 6.7.3에도 적용된다. 위의 단락 번호는 정기적으로 수정되는 2013년 RID/ADR 관련사항에 대한 것이다. 이로 인해 일시적으로 EN 14025의 불일치가 발생할 수 있다. RID/ADR의 요구 사항이 이 표준의 어떤 조항보다 우선시된다는 사실을 알고 있어야 한다. 그 외에 명시되어 있지 않은 경우, 페이지 전체를 차지하는 규정은 모든 유형의 탱크에 적용된다. 한 열에 포함된 규정은 다음과 같다: RID/ADR 6.8장에 따라 도로와 철도 압력탱크 (왼쪽 열) 및 RID/ADR 6.7장에 따라 이동식 탱크 (오른쪽 열).
