How should all the equipment be marked?
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 that is easy to read.
These are the components that generally need to be marked and how this mark should be done:
Automated water jetting equipment marking:
- Pumps: They should be fitted with a permanently mounted nameplate that 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: manufacturer’s 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 the following information can be clearly identified: the assembler, date of assembly, date of testing, and maximum operating pressure.
- Re-ended and retested hoses: Hose assemblies that have been re-ended or retested should be marked so the following information can be identified: the organisation performing the work, the organisation performing the retesting, the date of testing, and reference to the test reports.
- Robots: They must be marked in the information plates with the CE compliance mark and the working pressure, if applicable.
Furthermore, when working on job sites that present specific risks, the high-pressure water jetting system and all its attachments must comply with additional requirements and be marked accordingly.
For example, when it comes to working in ATEX environments – where automated cleaning has one of its primary applications – all components of the equipment must comply with all ATEX specifications and must be marked as indicating such compliance. There are different zones of ATEX, and each zone has different standards for its equipment. Hence, markings must indicate which ATEX zone equipment is valid.
