1. accord with the model implication's rules to select regularly, and ex-mark should be added behind model implication. the template is as following: code for product model implication ex-mark.for example, we need explosion-proof connector (change size) , thread specification is g½. the model implication is “bgj-b½(f)/½(m) exdⅱgb”.
2. if there are some special requirements, it should be pointed as ordering.
