Liquid petroleum products - Determination of contamination in middle distillates
This European Standard specifies a method for determining contamination as the content of undissolved substances in diesel fuel containing up to 5 % (V/V) fatty acid methyl esters (FAME) and in 100 % (V/V) FAME from 6 mg/kg to 30 mg/kg.
NOTE 1 Excessive contamination in a fuel system can give rise to premature blocking of filters and / or hardware failure, and is therefore undesirable.
This standard applies to liquid petroleum products having a kinematic viscosity not exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, e.g. diesel fuel as specified in EN 590 or light fuel oils.
Although the test method precision has not been defined, the method described may also be used for diesel fuel with FAME content different from that specified, and for petroleum products having a viscosity exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C.
NOTE 2 For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction.
WARNING — Use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
Flüssige Mineralölerzeugnisse - Bestimmung der Verschmutzung in Mitteldestillaten
Diese Europäische Norm legt ein Verfahren zur Bestimmung der Verschmutzung als Gehalt an ungelösten Stoffen in Mitteldestilaten mit einem Anteil von bis zu 5 % (V/V) Fettsäuremethylester (en: fatty acid methyl ester; FAME) und in 100 % (V/V) FAME fest. Dieses Verfahren kann auf Verschmutzungsgehalte im Bereich von 6 mg/kg bis 30 mg/kgN ) angewendet werden.
ANMERKUNG 1 Eine starke Verschmutzung im Kraftstoffsystem kann zum frühzeitigen Verstopfen der Filter und/oder Geräteversagen führen und ist deshalb unerwünscht.
Dieses Verfahren gilt für flüssige Mineralölerzeugnisse mit einer kinematischen Viskosität nicht über 8 mm2/s bei 20 °C bzw. 5 mm2/s bei 40 °C, z. B. Dieselkraftstoffe nach EN 590 [1] oder leichtes Heizöl.
Obwohl die Präzision für dieses Prüfverfahren noch nicht bestimmt wurde, darf dieses Verfahren auf Mischungen, dessen Gehalt an FAME mehr als 5 % (V/V) beträgt, angewendet werden, genauso wie auf Mineralölerzeugnisse mit einer kinematischen Viskosität über 8 mm2/s bei 20 °C bzw. 5 mm2/s bei 40 °C.
ANMERKUNG 2 Für den Zweck dieser Europäischen Norm wird das Symbol % (V/V) verwendet, um Volumenanteile in % auszudrücken.
WARNUNG Die Anwendung dieser Norm kann den Einsatz gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Diese Norm gibt nicht vor, alle mit ihrer Anwendung verbundenen Sicher¬heitsprobleme anzusprechen. Der Anwender dieser Norm ist dafür verantwortlich, vorher ange¬messene Maßnahmen hinsichtlich Sicherheit und Gesundheit zu ergreifen und die Anwendbarkeit einschränkender Vorschriften zu ermitteln.
Produits pétroliers liquides - Détermination de la contamination des distillats moyens
La présente Norme européenne prescrit une méthode de détermination de la contamination, définie comme la
teneur en substances non dissoutes dans les distillats moyens contenant jusqu’à 5 % (V/V) d’esters
méthyliques d’acides gras (EMAG) et dans les EMAG purs. Cette méthode peut être appliquée pour des
teneurs en contaminant allant de 6 mg/kg jusqu’à 30 mg/kg.
NOTE 1 Une contamination excessive peut provoquer un encrassement prématuré des filtres et / ou une panne de la
mécanique et n'est par conséquent pas souhaitable.
Cette norme s'applique aux produits pétroliers liquides dont la viscosité cinématique ne dépasse pas 8 mm2/s
à 20 °C ou 5 mm2/s à 40 °C, par exemple les carburants pour moteurs diesel spécifiés dans la norme EN 590
[1] ou les fuels-oils légers.
Bien que la fidélité de la méthode d’essai n’ait pas été définie, la méthode décrite peut aussi être utilisée avec
des mélanges contenant des EMAG d’une teneur supérieure à 5 % ou avec les produits pétroliers dont la
viscosité est supérieure aux valeurs indiquées au paragraphe précédent.
NOTE 2 Pour les besoins de la présente norme européenne, l'expression « % (V/V) » est employée pour représenter
la fraction volumique.
AVERTISSEMENT - L'utilisation de la présente norme implique l'intervention de produits,
d'opérations et d'équipements à caractère dangereux. La présente Norme européenne n'est pas
censée aborder tous les problèmes de sécurité concernés par sa mise en oeuvre. Il est de la
responsabilité de l'utilisateur de consulter et d'établir des règles de sécurité et d'hygiène appropriées
et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.

SIST EN 12662:2008은 중간 증류유의 오염도 측정을 위한 방법을 규정한 유럽 표준으로, 이 표준은 디젤 연료에서 최대 5% (V/V) 지방산 메틸 에스터(FAME)가 포함된 경우와 100% (V/V) FAME에서 6mg/kg에서 30mg/kg의 범위 내에서 용해되지 않은 물질의 함량을 측정하는 데 중점을 두고 있습니다. 이 표준은 액체 석유 제품이 20°C에서 8 mm²/s, 40°C에서 5 mm²/s를 초과하지 않는 운동 점도를 갖는 경우에 적용됩니다. 이 표준의 강점 중 하나는 디젤 연료와 경유처럼 EN 590에 명시된 연료 제품을 포함하여 다양한 액체 석유 제품의 오염도를 정확하게 평가할 수 있다는 점입니다. 또한, 이 표준은 FAME 함량이 명시된 것과 다르거나 점도가 8 mm²/s를 초과하는 석유 제품에 대해서도 활용할 수 있는 유연성을 제공합니다. 이는 다양한 연료 시스템에 적용할 수 있는 유용한 도구가 됩니다. 이 표준은 연료 시스템에서 과도한 오염이 필터의 조기 차단 및 하드웨어 고장을 초래할 수 있다는 경고를 포함하고 있어, 사용자들이 이러한 안전 문제를 충분히 인지하고 대처할 수 있도록 합니다. 그러나 사용자는 이 표준의 사용에 따른 위험 물질, 작업 및 장비와 관련된 모든 안전 문제를 충분히 이해하고 적절한 안전 및 건강 관행을 수립해야 합니다. 결론적으로, SIST EN 12662:2008은 액체 석유 제품의 오염도를 측정하는 데 필수적인 기준을 마련하여, 연료 품질 보증 및 시스템 신뢰성을 높이는 데 기여하는 중요한 표준입니다.
標準文書「EN 12662:2008」のレビューは以下の通りです。 この標準は、液体石油製品における中間留分の汚染物質の測定方法を定めており、特にディーゼル燃料に含まれる不溶性物質の含有量を測定することに焦点を当てています。具体的には、最大5％(V/V)の脂肪酸メチルエステル（FAME）を含むディーゼル燃料および100％(V/V)のFAMEにおける汚染物質の範囲は6 mg/kgから30 mg/kgです。この明確な範囲指定は、ディーゼル燃料の品質管理において非常に重要な役割を果たしています。 この標準の強みの一つは、フィルターの早期ブロックやハードウェアの故障を避けるため、汚染物質の適切な管理を促す点です。これは、エネルギー供給の効率を保つためにも不可欠であると言えます。また、指定された動粘度基準（20°Cで8 mm²/s、40°Cで5 mm²/s）を満たす液体石油製品に幅広く適用でき、EN 590で規定されたディーゼル燃料や軽油も含まれるため、業界全体での一貫した使用が期待できます。 さらに、計測方法の精度は明示されていないものの、FAMEの含有量や動粘度基準を超えた石油製品にも使用できる柔軟性があります。この点は、さまざまな製品の状況に応じた応用を可能にするため、利用者にとって大きな利点となります。 ただし、安全性の観点から注意が必要であり、危険な材料や操作、機器を伴う可能性があるため、ユーザーが適切な安全対策を講じることが求められます。この標準は、安全や健康に関するすべての問題を取り扱うものではないため、適用する際には規制の制約を確認することも重要です。 以上のように、EN 12662:2008は液体石油製品の品質管理において重要な指針を提供しており、その範囲、強み、関連性は業界内での利用価値を高めています。
The standard EN 12662:2008 specifies a method for determining contamination in liquid petroleum products, particularly focusing on middle distillates such as diesel fuel containing up to 5 % (V/V) fatty acid methyl esters (FAME). The scope of this standard is particularly relevant given the growing use of FAME in diesel fuels, as it addresses potential contamination levels from 6 mg/kg to 30 mg/kg. Excessive contamination can lead to premature blocking of filters and hardware failure, emphasizing the importance of this standard for maintaining fuel quality and system integrity. One of the strengths of EN 12662:2008 lies in its comprehensive approach to contamination measurement. By specifying the limits of kinematic viscosity-8 mm2/s at 20 °C and 5 mm2/s at 40 °C-it ensures that the method is applicable to a wide range of diesel fuels and light fuel oils. This specificity helps fuel manufacturers and users guarantee compliance with quality standards, thereby promoting operational efficiency. Additionally, the standard’s flexibility is notable; while it primarily applies to fuel with defined FAME content, it also acknowledges that the method can be adapted for diesel fuel with different FAME contents and petroleum products with higher viscosities. This adaptability reinforces the standard's relevance in a rapidly evolving market where fuel formulations may vary. However, it's important to recognize that while EN 12662:2008 offers an effective method for assessing contamination, it does not provide specific definitions for test method precision. Users must remain aware of this limitation and use the standard as part of a broader quality assurance protocol. The inclusion of a warning about the potential hazards associated with the use of this standard further underscores its significance. Users are reminded of their responsibility to establish safety practices and adhere to regulatory requirements, ensuring that while contamination is monitored, safety is also prioritized. Overall, EN 12662:2008 stands as a crucial standard for anyone involved in the production, distribution, and use of diesel fuel and related products. Its detailed approach to contamination measurement aligns well with the industry's need for quality assurance, making it highly relevant in contemporary fuel management practices.
