The movement must be sufficient to move the joint being checked. No movement should be visible in the joint. If any movement exists, continue to tighten until no movement is visible. Connections into fittings are made using the normal bell and spigot methods. 1.6.5 Adhesive Cure Time Cure time is the time required for the adhesive in the as- sembled joint to harden. Cure time depends on the type of adhesive and the ambient temperature, as shown in Fig. FIGURE 1.6.14 1.6.16. Separate wrenches are available from Smith Fiberglass Figure 1.6.16 Products for each size pipe. The wrenches lock around Ambient Temperature vs.Time to Pressure the pipe and force the pipe into a very slight oval DS-7000&DS-8000 shape.
