本欧洲标准规定了在40 mg/kg至100 mg/kg范围内测定液化石油气（LPG）中溶解残留物质的方法。可以通过调整样品量来确定更高的浓度。 溶解的残留物是在环境温度下蒸发样品后，然后在105℃的烘箱中可通过气相色谱检测的有机化合物的量。 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）。 从有限的LPG样品尺寸（50g至75g）的分析中，该方法允许获得关于残留物的潜在来源（气油，润滑剂，增塑剂等）的信息。 该方法的精密度数据由20mg/kg至100mg/kg测定。对于较高含量的残留物，精度尚未测试。 注意另一种欧洲标准EN 1547113 [1]规定了重量法。 警告 - 本标准的使用可能涉及危险材料，操作和设备。本标准并不旨在解决与其使用相关的所有安全问题。本标准用户有责任采取适当措施，确保在使用标准之前人员的安全和健康

This European Standard 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 that are 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 1547113[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.
