Which information is required to be recorded during the leak testing process?

Recording the date, gauge model, and serial number during the leak testing process is essential for maintaining accurate records and ensuring traceability of the gauge being tested. This information is crucial for several reasons:

1. Traceability: The gauge model and serial number allow technicians to identify the specific equipment that was tested. This is important for accountability and future reference, especially if issues arise later on.

2. Documentation: Keeping a record of the date of the test provides a timeline for when the gauge was last inspected for leaks. This helps in ensuring that all equipment is maintained according to regulatory and safety standards.

3. Regulatory Compliance: Many organizations require precise documentation as part of compliance with safety and operational regulations. Having the gauge model and serial number helps demonstrate adherence to these standards.

While other options such as gauge temperature readings, last inspection date, and current weather conditions may be relevant in specific contexts, they are not universally required for every leak testing scenario. They may serve other purposes but do not fulfill the primary need for traceability and identification during the leak testing process.
