As part of the development of a new standard testing procedure, a round robin study was conducted by six participating laboratories. This study involved the measurement of both the maximum explosion pressure and the maximum rate of pressure rise for hybrid mixtures comprising dust and vapor. Measurements were performed using a modified 20L-sphere. The primary objective of this collaborative effort was to assess the accuracy, reliability, and consistency of analytical and measurement methods across multiple laboratories, thereby increasing confidence in the obtained results. The method and protocol were developed as part of the NEX-HYS project and documented in a technical specification by the German Institute for Standardization Registered Association (DIN). The study revealed that precise pre-ignition pressure rise (PIPR) measurements and the use of a leak-free test apparatus significantly influenced the results of the measured maximum explosion pressure and maximum pressure rise rate.

关于蒸汽和粉尘混合混合物安全特性的欧洲循环赛

作为制定新标准测试程序的一部分，六个参与实验室进行了循环研究。这项研究涉及对由灰尘和蒸汽组成的混合混合物的最大爆炸压力和最大压力上升速率的测量。使用改进的 20L 球体进行测量。这项合作的主要目标是评估多个实验室的分析和测量方法的准确性、可靠性和一致性，从而提高对所获得结果的信心。该方法和协议是作为 NEX-HYS 项目的一部分开发的，并由德国标准化协会注册协会 (DIN) 记录在技术规范中。研究表明，精确的预燃压升（PIPR）测量和无泄漏测试设备的使用显着影响了最大爆炸压力和最大压力上升率的测量结果。
