THE REVISED PHILIPPINE MECHANICAL ENGINEERING CODE: FOCUS ON IMPROVING THE QUALITY OF THE ENVIRONMENT, LIFE, SAFETY AND HEALTH The Philippine Society of Mechanical Engineers is the Philippines’ only integrated technical society in the field of mechanical engineering. Its members, scattered throughout the world are individuals who share ideas, support research, identify needs, and write the Philippine industry’s standards for testing and practice. The result is that engineers are better able to keep indoor environments safe and productive while protecting and preserving the outdoors and the environment for generations to come. There are noticeable differences between this Revised Code and the previous versions: The earlier version/s were written more as a reference manual instead of a code, they describe theories and practices in operation rather than follow the mandate in accordance with the National Building Code of the Philippines and, they have not been updated to conform with current practices in accordance with international standards and norms. This new code follows stipulated international practices and the uniform mechanical code, and focuses on the paramount concern in the world today, the environment, life, safety and health. The PSME is tasked to safeguard the people by all means in compliance with the National Building Code of the Philippines, specifically Section 102 Declaration of Policy and Chapter 13, Section 1302 Mechanical Regulation. One of the ways that PSME supports its members and the industry’s need for information is through PSME Research enabling members to benefit from the combined effort of committee members who have the experience in determining the important information that is incorporated in this Code. The 2011 Philippine Mechanical Engineering Code The 2011 Philippine Mechanical Engineering Code covers basic principles and data used in the mechanical engineering field. The PSME Technical Committee that prepared these chapters, strive not only to provide new information, but also to clarify past and existing information, delete obsolete materials, and reorganize the chapters and their contents to make the Code more understandable and easier to use.
Unlike a Handbook, this Code is intended not only for mechanical engineers but also to the general public as well. A code is full of terms, information and guidelines. A handbook helps to explain things and principles on how an object, a process, and a system functions. The intent of this Code is to cover mechanical engineering practice for multiple residential, commercial and industrial edifices, typically where the greater population reside and work. There is a limit where we cannot cover plant manufacturing processes such as cement plants, oil refineries, power plants and the like simply because these are business concerns with proprietary rights to their technology. Further, the people interaction is not with the public but limited only to experienced personnel and experts with interests to such a facility. For an engineer to learn the principles on how these plants work and operate, he only has to refer to a Handbook. Despite this situation, we have endeavored to cover in this Code the minimum mandatory requirement on how to properly install mechanical equipment to protect the public. Likewise, the language in this Code is written to be understood by everyone and not only mechanical engineers, in support of the mandate bestowed upon us by the National Building Code of the Philippines. A typical user of this Code, be he a building official, a government engineer, a trade practitioner who may be a project owner, a consultant, or an engineering supplier, reading, interpreting or conceptualizing designs, preparing or writing reports, specifications and other documents related to a project, a contractor who undertakes the scheduling, building and commissioning of a small or large project, even a foreign entity who joins bids, read the terms of references and carry out the tasks involved in the project he will be doing refer to such a Code as mandated by the government for the interest of the general public’s welfare on the preservation of the environment, the protection of life, the safeguarding of one’s safety and to shelter each individual’s health within and without the workplace. The reader will view the chapters as new but, as soon as he comprehends the contents, knowledge gained will germinate into creative ideas, and applications will come in as second nature but achieving the wisdom that he is preserving his surroundings and the population that might be affected with his decisions. This edition radically departs from the previous editions in that the Technical Committee adopted the Uniform Mechanical Code which has been in use all over the world by both developed and developing countries, to suit our local climatic conditions and practical usage.
