Engineering design standards are not meant to be rigid and restrictive, but rather to be flexible and adaptable to different contexts and situations. To use engineering design standards effectively, you should identify the relevant standards for your design problem and solution, understand the purpose, scope, and content of the standards, apply the standards to your design process and product, and evaluate and validate your design outcomes using the standards. You can consult various sources, such as online databases, libraries, catalogs, or experts, to find the most applicable and up-to-date standards for your engineering project. Additionally, you should read and interpret the standards carefully, pay attention to the definitions, symbols, units, formats, and references that they use, follow the standards as closely as possible while documenting your compliance and deviations, use the standards as a reference and a resource for your design decisions and actions, seek feedback and guidance from the standards developers or users when needed, use the standards as a basis and a tool for testing, verifying, and validating your design results and performance, and use the standards as a means and a medium for communicating and demonstrating your design quality, safety, reliability, and interoperability.
