C57.12.00 and C57.12.90 are unique in the sense that they are "base standards", which the product standards build upon, undergoing continuous review and revision. C57.12.00 and C57.12.90 are also considered "companion standards": C57.12.00 sets the performance requirements, and C57.12.90 defines the test requirements and procedures necessary to
