Manufactured assemblies employing flexible hose do not need to be labeled with ______.

The correct answer pertains to the labeling requirements of manufactured assemblies that utilize flexible hose in medical gas systems. According to industry standards, while it is critical for these assemblies to be marked with certain vital information to ensure safety and compliance, the specific requirement for labeling with a "standard pressure" is not mandated.

When flexible hose assemblies are designed and manufactured, they are typically labeled with essential information such as the maximum pressure rating, which indicates the highest pressure the hose can safely handle during operation. This is crucial for preventing over-pressurization and ensuring the safety of the medical gas delivery system. Safety warnings are also a necessary component of the labeling to inform users of potential hazards associated with the use of the hose.

Additionally, the manufacturer's name must be provided on the assembly to ensure traceability and accountability in case of defects or issues. This identification helps maintain product integrity and facilitates any necessary recalls or safety inspections.

Therefore, while maximum pressure rating, safety warnings, and the manufacturer's name are required for labeling flexibility hose assemblies, the labeling need does not extend to a "standard pressure," which does not have the same level of necessity for operational safety, leading to its omission in this context.
