Abstract

This test method deals with gray irons that are to be free of chill in the casting and to chilled irons that are to have a specific depth of chill in the casting. The purpose of the test is to determine the chilling tendencies of cast iron. The two tests are wedge test and chill test. Both tests shall be made in a core which may either be single cores or gang cores and a pouring practice shall be performed. The wedge test is generally better adapted to the higher strength gray irons. The accelerated cooling rate that shall induce the formation of a chill shall be brought about through the design of the test specimen. The chill test is better adapted to the softer grades of gray iron and should be used if the casting have a specified depth of chill. The chill in this type of test shall be induced by casting one edge of the test specimen against a metal or graphite chilled plate or block. Wedge test is simpler than chill test since in the wedge test, maintenance of chill blocks or plates is not necessary.

Scope

1.1 These test methods of chill testing apply to gray irons that are to be free of chill in the casting and to chilled irons that are to have a specific depth of chill in the casting. Two test methods of determining the chilling tendencies of cast iron are covered as follows. For many applications either test method will be satisfactory if test pieces of the proper dimensions are selected.

1.1.1 Test Method A, Wedge Test—This test is generally better adapted to the higher strength gray irons. The accelerated cooling rate to induce the formation of a chill is brought about through the design of the test specimen. This test method is simpler than Test Method B since maintenance of chill blocks or plates is not necessary.

1.1.2 Test Method B, Chill Test—This test is better adapted to the softer grades of gray iron and should be used if the casting is to have a specified depth of chill. The chill in this type of test is induced by casting one edge of the test specimen against a metal or graphite chilled plate or block.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
