All the components which need to be identified for service, maintenance or application should be permanently marked with enough information to identify the part, its use and performance and in a way which is easy to read.
Generally, the following components must be marked with:
- Pumps. They should be fitted with a permanently mounted name plate which provides the following information: manufacturer’s name or mark, model designation, serial number, year of manufacture, maximum volume and pressure performance, maximum input speed and maximum operating pressure.
- Hoses. They should be marked with the following information: manufacturers identification, date of manufacture, maximum temperature and maximum operating pressure.
- Adaptors and end fittings. They should be marked so the manufacturer’s identification and maximum operating pressure can be identified.
- Hose assemblies. They should be marked so that the appropriate certificate containing the following information can be clearly identified: the assembler, date of assembly, date of testing, maximum operating pressure.
- Re-ended and retested hoses. Hose assemblies which have been re-ended or retested should be marked so that the appropriate certificate containing the following information can be identified: the organisation performing the work, the organisation performing the retesting, date of testing, reference to the test reports.
