- Scope
- JB/T 7945-1999 This standard is a revision of JB/T 7945-95 "Test Methods for Mechanical Properties of Gray Cast Iron". During the revision, only editorial modifications were made in accordance with relevant regulations, and the technical content has not changed. This standard specifies the test methods for mechanical properties such as tensile strength, flexural strength, deflection, compressive strength, and compression ratio of gray cast iron. This standard is suitable for measuring the mechanical properties of gray cast iron under normal temperature static conditions. This standard was first released as GB 977-84 in 1984, and was adjusted to JB/T 7945-95 in April 1996.
