《GB/T 2433-2001添加剂和含添加剂润滑油硫酸盐灰分测定法》由TC280(全国石油产品和润滑剂标准化技术委员会)归口,TC280SC1(全国石油产品和润滑剂标准化技术委员会石油燃料和润滑剂分会)执行,主管部门为国家标准化管理委员会。
本标准规定了测定未经使用的含添加剂润滑油和用于调和润滑油的添加剂浓缩物中硫酸盐灰分质量分数的方法。这些添加剂通常含有一种或多种金属:钡、钙、镁、锌、钾、钠和锡素。而素硫、磷和氯则以结合形式存在。本标准测定的硫酸盐灰分的质量分数下限为0.005%。当硫酸盐灰分小于0.02%时,本标准仅适用于只含有无灰添加剂润滑油。本标准不适用于测定用过的含铅添加剂的发动机油,也不适用于不含添加剂润滑油,对于这些油品可以采用GB/T 508。硫酸盐灰分可以用来表明新润滑油中已知的含金属添加剂的浓度。当不含磷时,钡、钙、镁、钾、钠转变为硫酸盐,锡(Ⅳ)和锌转变为它们的氧化物,硫和氯并无干扰。但是当磷与金属添加剂同时存在时,它以金属磷酸盐的形式部分或全部保留在硫酸盐灰分中。本标准涉及某些危险材料、操作和设备。但无意对于此有关的所有安全问题都提出建议。因此,用户在使用本标准之前应建立适当的安全和防护措施并确定有适用性的管理制度。


1.1 This standard specifies the method to determine the mass fraction of sulfated ash in the unused lubricating oil with additives and the additive concentrate used for blending lubricating oil. These additives generally contain one or several kinds of metallic elements: barium, calcium, magnesium, zinc, potassium, sodium and tin element. However, elements such as sulfur, phosphorus and chlorine exist in combined form.
