What is the certification recognized for mastering safety standards in the amusement industry?

The correct certification recognized for mastering safety standards in the amusement industry is ASTM Certification. This certification is issued by the American Society for Testing and Materials and is crucial in ensuring that amusement rides and park operations adhere to specific safety standards. The ASTM develops and publishes voluntary consensus technical standards that are widely accepted and adopted within the amusement industry, which helps ensure the safety and reliability of rides and attractions for guests.

The other options, while they may relate to safety or operational procedures within the amusement industry, do not hold the same level of recognition specifically for safety standards. For instance, iROC Certification is related to a different aspect of operational training, while the Amusement Safety Certification and Ride Operator Certification do not have the same authority or comprehensive recognition in the context of safety standards as ASTM Certification.
