“IIAR 9 – Minimum System Safety Requirements for Existing Closed-Circuit Ammonia Refrigeration Systems” is now available for purchase.

This standard provides a method for existing stationary closed-circuit refrigeration systems using ammonia as the refrigerant to evaluate and document new and revised codes, standards and practices to determine what provision should be implemented in the existing system. This standard also provides a method for determining and documenting existing equipment designed and constructed in accordance with prior codes, standards or practices to ensure practices and system designs remain safe for operation.
