Basis and References for the Revised Procedures
- The revised procedures conform to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code and the National Board Inspection Code.
- Additional references include boiler inspection codes from England, France, and Germany.
Reasons for Revising the Testing and Inspection Procedures
- Updates incorporate latest developments and accepted mechanical engineering practices from developed countries.
- The revision reflects advancements in metallurgy, fabrication, design, and manufacturing technologies.
- Provides appropriate testing and inspection protocols for new generation boilers to ensure safety and equipment integrity.
Prescribed Hydrostatic Testing Requirements
- In new boiler installations, hydrostatic tests must be conducted at 1.5 times the design pressure before operation.
- Subsequent hydrostatic testing is required every 5 years at test pressures between 1.2 and 1.5 times the Maximum Allowable Working Pressure.
- Hydrostatic testing during maintenance shutdowns should not exceed the safety valve with the lowest set pressure.
Legal and Professional Integration
- The revised procedures are incorporated into the Code of Professional Standards for mechanical engineers under Section 9(h), Article II of Republic Act No. 8495 (Philippine Mechanical Engineering Act of 1998).
Effectivity and Dissemination
- The resolution takes effect 15 days after full publication in the Official Gazette or a newspaper of general circulation.
- Copies of the Resolution are to be furnished to the PSMEI President, the Secretary of the Department of Labor and Employment, and other concerned parties.
