BS EN 15471:2017规定了测定液化石油气中溶解残余物的方法 使用喷射蒸发设备在105°C下蒸发后残留的石油气（LPG） 如EN ISO 6246所述。测量范围为20 mg/kg至100 mg/kg。更高的浓度可通过以下方法确定: 调整样本量。该方法的精密度数据测定范围为20 mg/kg至100 mg/kg，样品量为 从100克到50克。注:替代欧洲标准EN 15470[1]规定了气相色谱法。 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 6246:2017EN ISO 4257（ISO 4257:2001 AS）ISO 4257:2001 Ed 2EN ISO 6246:2017ISO 4259:2006 Ed 3EN ISO 4259（ISO 4259:2001 AS） 2006）ASEN 15470:2017购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 15471:2017 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.Cross References:ISO 6246:2017EN ISO 4257 (ISO 4257:2001 AS)ISO 4257:2001 Ed 2EN ISO 6246:2017ISO 4259:2006 Ed 3EN ISO 4259 (ISO 4259:2006) ASEN 15470:2017All current amendments available at time of purchase are included with the purchase of this document.
