在ISO/TS 29041:2008中，研究了ISO 6142中给出的重量混合物制备中存在的先验影响，以及通过数据处理引入的相关性。所有计算都涉及如下目标组成的合成天然气的制备:1.4 mol%N2、1.8 mol%CO2、9.4 mol%乙烷、3.4 mol%丙烷、1 mol%正丁烷和83 mol%甲烷。本实施例给出的关于混合物可行性、制备程序的选择以及称重步骤和顺序的所有考虑与ISO 6142中给出的相同。这也适用于基本不确定性源的所有估计和用于制备的气体的纯度表。
In ISO/TS 29041:2008, the gravimetric mixture preparation as given in ISO 6142 is investigated for existing a priori influences, as well as correlations introduced by data processing.All calculations refer to an example which consists in the preparation of a synthetic natural gas of a target composition as follows: 1,4 mol % N2, 1,8 mol % CO2, 9,4 mol % ethane, 3,4 mol % propane, 1 mol % n-butane, and 83 mol % methane.All considerations given for this example concerning mixture feasibility, choice of preparation procedure, and weighing steps and sequences are the same as given in ISO 6142. This also applies to all estimates for basic uncertainty sources and the purity tables of the gases used for preparation.
