There are several engineering codes and standards that engineering students should be familiar with for the optional subject. These codes and standards play a crucial role in ensuring safety, quality, and efficiency in engineering practices. Familiarity with these codes and standards is essential for engineers to design, construct, and maintain various engineering projects. Some of the important engineering codes and standards are:

1. American Society of Mechanical Engineers (ASME) Codes:
- ASME Boiler and Pressure Vessel Code (BPVC): It provides guidelines for the design, fabrication, and inspection of boilers and pressure vessels.
- ASME B31 Code for Pressure Piping: It establishes requirements for the design, fabrication, inspection, and testing of process piping systems.

2. International Building Code (IBC):
- It is a comprehensive set of regulations for the design and construction of new buildings. It covers various aspects such as structural, fire safety, plumbing, and electrical systems.

3. National Electrical Code (NEC):
- It is a standard for electrical installation and is adopted by many countries. It provides guidelines for the safe installation of electrical wiring and equipment.

4. International Organization for Standardization (ISO) Standards:
- ISO 9001: It sets out criteria for a quality management system and is widely used for quality assurance in engineering industries.
- ISO 14001: It provides guidelines for an environmental management system, helping organizations to minimize their environmental impact.

5. American Concrete Institute (ACI) Codes:
- ACI 318: It provides requirements for the design and construction of structural concrete elements in buildings and other structures.

6. Occupational Safety and Health Administration (OSHA) Standards:
- OSHA 1910: It contains regulations for workplace safety and health, including guidelines for hazard communication, machine guarding, and personal protective equipment.

7. International Electrotechnical Commission (IEC) Standards:
- IEC 60601: It is a series of standards for the safety and performance of medical electrical equipment.

8. Institute of Electrical and Electronics Engineers (IEEE) Standards:
- IEEE 802.11: It defines standards for wireless local area networks (WLAN), commonly known as Wi-Fi.

It is important for engineering students to study and understand these codes and standards as they form the basis for designing and implementing engineering projects. These codes and standards ensure that engineering practices meet the required safety, quality, and performance standards, leading to reliable and sustainable infrastructure development.
