Regarding the classification of conical heads in GB/T25198-2023
Thread Content
Head standard: GB/T25198-2023, which came into effect on March 1, 2024. 1. As mentioned in clause 5.1.1, design details shall also be provided for the end caps in Table 2. 2. In Table 2, the conical heads are divided into three types: CNA, CSA, and CDA, and the half-cone angle is replaced by α. So: 1. Since design details need to be provided and no angle is specified, why not use CHA(α) to cover all types? 2. Since they are divided into three types: CNA, CSA, and CDA, what are the respective limitation ranges for each of these three types? 3. It’s not possible to follow the 2023 version of the standards; instead, one has to turn to the 2010 version in order to find the relevant guidelines and parameters.
Bugs in the new standard, please explain!
