NB/SH/T 6006-2020 石油产品铜腐蚀性快速试验 一次性铜箔片 Standard test method for rapid determination of corrosiveness to copper from
本标准规定了用一次性铜箔片快速评价石油产品铜腐蚀性的试验方法。<br />本标准适用于测定航空汽油、喷气燃料、车用汽油、稳定轻烃或在37.8℃时蒸气压不大于124kPa的其他烃类、溶剂油、煤油、柴油、馏分燃料油、润滑油和其他石油产品对铜的腐蚀程度。<br />警示:有些产品,如稳定轻烃,其蒸气压比车用汽油或航空汽油的典型蒸气压高,因此应特别注意,不要把装有高蒸气压的稳定轻烃或其他产品的压力容器放到100℃浴中。蒸气压超过124kPa的试样在100℃时<br />能产生很大的压力,会使压力容器破裂;故对蒸气压超过124kPa的试样,应采用SH/T0232测定。...
