Codes and Standards
Codes and standards are sets of rules and guidelines that are developed and maintained by professional organizations, government agencies and other bodies to ensure the safety, quality and effectiveness of products, services and processes. They are used in a wide range of industries, including construction, manufacturing, health care and information technology. Codes are legally enforceable regulations that are established by local, state or federal governments to ensure the safety and welfare of the public. They may cover a wide range of topics, including building construction, electrical systems, plumbing and fire safety. Standards, on the other hand, are voluntary guidelines that are developed by professional organizations, industry groups and other bodies to establish best practices and ensure the quality and performance of products and services. Standards may be developed for a specific industry or technology or they may be more general in nature. Codes and standards are important because they provide a common set of rules and guidelines that can be followed by companies, individuals and other organizations. They help ensure the safety and quality of products and services and they can help reduce the risk of accidents and injuries.

Codes and standards insights
- Codes, standards and guidelines must be followed when retrofitting existing or designing new buildings.
- The primary code bodies that consulting engineers are concerned with are NFPA and ASHRAE.
Mechanical, electrical, plumbing, fire protection, lighting and other commercial building system design is dictated by a variety of codes and standards. They define the minimum requirements for the design of new buildings or the retrofit of existing buildings.
These codes and standards are updated on a regular cycle, typically every three years. They are then adopted by the local authority having jurisdiction on a timeline that suits the state, city or region. Engineers must adhere to the code, and ensure the design meets the minimum requirements.
Two key code-creating bodies are the National Fire Protection Association and the American Society of Heating, Refrigerating and Air Conditioning Engineers. NFPA produces codes and standards on topics mostly related to fire, life safety and electrical/power systems. ASHRAE produces codes and standards on heating, ventilation, air conditioning and refrigeration topics.
There are a variety of specialized standards, including those from Facility Guidelines Institute, the RESET Standard and others. In addition, the International Code Council releases several codes related to energy efficiency, fire protection and plumbing systems, to name a few.
Standards bodies, government institutions and associations manage them.
Codes and Standards FAQ
What are engineering codes and standards?
Engineering codes and standards are sets of guidelines and rules that are used to ensure the safety, reliability and performance of engineered systems, such as fire and life safety, electrical systems and mechanical systems. They are developed by industry organizations, government agencies and professional societies and are adopted by local, state and federal governments as mandatory regulations.
Some examples of engineering codes and standards include:
- Building: These codes set minimum standards for the design, construction and maintenance of buildings, including requirements for fire and life safety, electrical system design and accessibility.
- Electrical: These codes set standards for the design, installation and maintenance of electrical systems, including requirements for wiring, grounding and overcurrent protection.
- Mechanical: These codes set standards for the design, installation and maintenance of mechanical systems, including requirements for HVAC, plumbing and fuel-gas systems.
- Seismic: These codes set standards for the design and construction of buildings and other structures to withstand seismic loads and ensure safety during earthquakes.
- Fire and life Safety: These codes set standards for the design and construction of buildings and other structures to protect against and prevent fire or life safety events.
- Energy: These codes set standards for energy efficiency in buildings, including requirements for insulation, lighting and HVAC systems.
These codes and standards are periodically reviewed and updated to reflect the latest technologies and building designs.
Why do we have codes and standards?
Codes and standards are developed and adopted to ensure the safety, reliability and performance of engineered systems. They provide guidelines and rules for the design, construction and maintenance of buildings, electrical systems, mechanical systems and other engineered systems. These codes and standards are put in place for several reasons:
- Safety: Codes and standards are developed to ensure the safety of the public and building occupants. For example, building codes set standards for fire safety, structural integrity and accessibility to ensure that buildings are safe for people to occupy.
- Reliability: Codes and standards are also developed to ensure that engineered systems are reliable and perform as intended. For example, electrical codes set standards for wiring, grounding and overcurrent protection to ensure that electrical systems are reliable and safe.
- Consistency: Codes and standards provide a consistent set of guidelines and rules for the design, construction and maintenance of engineered systems. This helps to ensure that buildings and other structures are designed and built to a consistent level of quality and safety, regardless of where they are located.
- Professionalism: Engineers, architects, contractors and other professionals involved in the design, construction and maintenance of engineered systems must adhere to these codes and standards to ensure that the systems they create and maintain are safe, reliable and perform as intended. It serves as a benchmark for professional practice, making sure that the minimum standards of safety and performance are met.
- Legal compliance: Adherence to codes and standards is often mandatory by law, to protect people and property and to ensure that buildings, structures and systems are safe and reliable.
Overall, codes and standards are an essential part of the design, construction and maintenance of buildings and other engineered systems, providing guidelines and rules that ensure safety, reliability and performance of these systems, while also protecting the public, building occupants and the environment.
Are codes and standards the same thing?
Codes and standards are related, but they are not the same thing.
A code is a set of regulations or laws that are adopted by a government or regulatory body and are legally enforceable. Building codes, electrical codes, plumbing codes and fire codes are examples of codes that are adopted by local, state or federal governments and are mandatory for the design, construction and maintenance of buildings, structures and systems.
Standards, on the other hand, are a set of guidelines or best practices that are developed and adopted by industry organizations, professional societies and other groups. They are not legally enforceable, but they are widely accepted and followed as a benchmark for good practice and quality. Standards are used to ensure the safety, reliability and performance of engineered systems, providing guidelines and rules for the design, construction and maintenance of buildings, structures and systems.
In summary, codes are mandatory regulations, while standards are voluntary guidelines. Codes are legally enforceable, while standards are not. However, codes and standards often complement each other, with codes setting the minimum standards and standards providing additional guidance on best practices.
Are codes and standards the same thing?
Codes and standards are not the same thing, but they are related. A code is a set of laws or regulations that have to be followed, while a standard is a set of recommended guidelines. Codes are often mandatory and enforced by the government agency, while standards are voluntary and often established by industry organizations or trade associations. However, codes and standards can overlap and compliance with a standard may be required to meet code requirements.
