Standard Practice for Making and Using C-Ring Stress-Corrosion Test Specimens
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers the essential features of the design and machining, and procedures for stressing, exposing, and inspecting C-ring type of stress-corrosion test specimens. An analysis is given of the state and distribution of stress in the C-ring.
1.2 Specific considerations relating to the sampling process and to the selection of appropriate test environments are outside the scope of this practice.
1.3 The values stated in SI units are to be regarded as the standard; The values given in parentheses are for information only.
1.4 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.
Significance and Use
The C-ring is a versatile, economical specimen for quantitatively determining the susceptibility to stress-corrosion cracking of all types of alloys in a wide variety of product forms. It is particularly suitable for making transverse tests of tubing and rod and for making short-transverse tests of various products as illustrated for plate in Fig. 1.
