1. Scope--This SAE Recommended Practice sets forth a method for evaluating the flow properties of automotive sealers that have been dispensed via a high pressure automatic system.
1.1 Background--For many years, automotive sealers were applied manually by means of an operator-held flow gun. The operator could adjust flow rates by hand speed and/or adjusting the pump pressures up or down as desired. Today, however, some sealers are applied by automated means such as robots, gantry tables, etc. To be effective, an automated system must be capable of applying material at a constant known rate. This demands that the equipment and material handling parameters remain constant, not changing from their initial setup.
