BS EN 15470:2017规定了测定液化石油气中溶解残余物的方法 石油气（LPG），在40 mg/kg至100 mg/kg范围内。更高的浓度可通过以下方法确定: 调整样本量。溶解残留物指的是经过处理后，通过气相色谱法可检测到的有机化合物量 在环境温度下蒸发样品，然后在105°C的温度下在烘箱中蒸发？C.该方法不适用于检测固体材料或可能的高摩尔质量聚合物 （>1000 g/mol）。通过分析有限的液化石油气样本量（50 g至75 g），该方法可获得以下信息: 残留物的潜在来源（汽油、润滑剂、增塑剂等）。该方法的精密度数据测定范围为20 mg/kg至100 mg/kg。为了更高的内容 关于残留物，精度尚未测试。注:替代欧洲标准EN 15471[1]规定了重量分析法。 警告——本标准的使用可能涉及危险材料、操作和设备。这 本标准并不是为了解决与其使用相关的所有安全问题。这就是 本标准的使用者有责任采取适当措施，确保使用者的安全和健康 在应用本标准之前，确保所有人员，并满足本标准的法定和监管要求 意图交叉引用:ISO 4257:2001 Ed 2EN ISO 4257（ISO 4257:2001 AS）ISO 4259:2006 Ed 3EN 15471:2017EN ISO 4259（ISO 4259:2006）以及购买本文件时可用的所有现行修订本。

BS EN 15470:2017 specifies a method for determining the dissolved residual matter in liquefied petroleum gases (LPG), in the range of 40 mg/kg to 100 mg/kg. Higher concentrations can be determined by adjusting the sample size.The dissolved residue is the amount of organic compounds which is detectable by gas chromatography after evaporation of the sample at ambient temperature and then in an oven at 105?C.This method is not suitable for detecting solid materials or for possibly high molar mass polymers (>1 000 g/mol).From the analysis of a limited LPG sample size (50 g to 75 g) this method allows obtaining information on the potential origin of the residue (gasoil, lubricants, plasticizers, etc.).The precision data of the method have been determined from 20 mg/kg to 100 mg/kg. For a higher content of residue, the precision has not been tested.NOTE An alternative European Standard, EN 15471 [1], specifies a gravimetric method.WARNING - The use of this standard can 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 users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.Cross References:ISO 4257:2001 Ed 2EN ISO 4257 (ISO 4257:2001 AS)ISO 4259:2006 Ed 3EN 15471:2017EN ISO 4259 (ISO 4259:2006) ASAll current amendments available at time of purchase are included with the purchase of this document.
