Pressure and strength tests are specified in which document?

• A. EN378
• B. ISO 9001
• C. ASHRAE 15
• D. EN12345

Answer: (A)

The document that specifies pressure and strength tests is EN378. This standard is crucial for ensuring the safety and performance of refrigeration systems. It provides guidelines for the design, construction, and testing of refrigeration systems that use flammable refrigerants or operate at pressures that could present risks.

EN378 outlines the methodologies for testing the integrity of system components under pressure to ensure that they can withstand operational and emergency conditions without failing. This is essential for maintaining safety standards and preventing leaks that could lead to hazardous situations.

While other standards such as ISO 9001 focus on quality management systems and ASHRAE 15 addresses safety requirements related to refrigerants, they do not specifically set forth the requirements for pressure and strength testing of refrigeration systems. EN12345 does not exist in the context of relevant standards for refrigeration; therefore, it is not applicable.
