ISO 15837:2004提供了垫圈机械联轴器所需的性能特征和鉴定试验，包括槽端管的槽型机械联轴器、平端管的机械约束联轴器和平端管的机械压缩联轴器。这些联轴器的使用温度在各自垫片的推荐温度范围内。

ISO 15837:2004 provides the performance characteristics and qualification tests required for gasketed mechanical couplings, including grooved-type mechanical couplings for grooved-end pipe, mechanical restraint couplings for plain-end pipe and mechanical compression couplings for plain-end pipe. These couplings are for use at temperatures within the recommended temperature range of their respective gaskets.
