Inter-laboratory reproducibility of biomethane potential (BMP) is dismal, with differences in BMP values for the same sample exceeding a factor of two in some cases. A large group of BMP researchers directly addressed this problem during a workshop held in Leysin, Switzerland, in June 2015. The workshop resulted in a new set of guidelines for BMP tests published in 2016, which is the subject of the present commentary. The work has continued with two international inter-laboratory studies and one additional workshop held in Freising, Germany, in 2018. The dataset generated by the two inter-laboratory studies were used to refine the validation criteria for BMP tests. Based on these new results an update to the original guidelines is proposed here.
实验室间生物甲烷潜能（BMP）的重现性较差，对于同一样品，BMP 值的差异在某些情况下超过两倍。2015 年 6 月，在瑞士莱森举行的一次研讨会上，一大群 BMP 研究人员直接解决了这个问题。该研讨会产生了一套新的 BMP 测试指南，并于 2016 年出版，这是本评论的主题。此后，又进行了两项国际实验室间研究和一次在德国弗赖辛举行的额外研讨会。这两项实验室间研究产生的数据集被用于改进 BMP 测试的验证标准。基于这些新结果，这里提出了对原始指南的更新。
