scope:

This test method is to be used for the evaluation of hand soldering tools under a simulated heavy load such as that presented by PWBs with abnormally thick ground or power planes. Separate test methods (IPC-TM-650, Methods 2.4.37 and 2.4.37.1) are provided for evaluation of tools under normal operating conditions. The purpose of this test method is to provide a means by which hand soldering tools may be evaluated under a standard controlled set of conditions. This method may be used to either evaluate a single tool's performance or for comparison of several tools.

Note: Tip geometry, mass, contact area (working face), contact angle, and idle temperature can significantly skew the test results.
