本欧洲标准规定了使用EN ISO 6246中描述的喷射蒸发设备，在105°C下蒸发之后，确定液化石油气（LPG）中溶解的残留物质的方法。 测量范围为20 mg/kg至100 mg/kg。可以通过调整样品量来确定更高的浓度。 该方法的精密度数据由20mg/kg至100mg/kg确定，样品量为100g至50g。 注意另一种欧洲标准EN 15470 [1]规定了气相色谱法。 警告 - 使用本标准可能涉及危险材料，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，确保人员在实施标准之前的安全和健康，并达到法定和法规要求

This European Standard specifies a method for determining the dissolved residual matter in liquefied petroleum gases (LPG), which remains after evaporation at 105 °C using the jet evaporation equipment described in EN ISO 6246. The measurement range is from 20 mg/kg to 100 mg/kg. Higher concentrations can be determined by adjusting the sample size. The precision data of the method have been determined from 20 mg/kg to 100 mg/kg, with samples amount from 100 g to 50 g. NOTE An alternative European Standard, EN 15470 [1], specifies a gas chromatography 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.
