Is ASME the same as ISO?


When it comes to technical standards, there are several organizations that play a crucial role in ensuring compatibility, quality, and safety across industries. ASME (American Society of Mechanical Engineers) and ISO (International Organization for Standardization) are two such institutions that set standards in various fields. In this article, we will explore the similarities and differences between ASME and ISO to understand their significance.

The Role of ASME

ASME, founded in 1880, is an organization primarily focused on mechanical engineering and related disciplines. It develops codes and standards for a wide range of industries, including oil and gas, power generation, pressure vessels, and more. ASME standards provide guidance on design, manufacturing, inspection, and maintenance practices to ensure safety, reliability, and quality.

Understanding ISO

ISO, established in 1947, is an international standard-setting body composed of national standards organizations from different countries. Unlike ASME, which focuses more on mechanical engineering, ISO covers a broader spectrum of industries and sectors. It creates standards for products, services, processes, and management systems, promoting international trade and enhancing global compatibility.

Key Differences

While both ASME and ISO aim to standardize procedures and improve product quality, there are some notable differences between the two:

1. Scope: ASME tends to be more industry-specific, focusing on mechanical engineering-related areas. ISO has a more extensive scope, encompassing multiple industries and sectors.

2. Global Applicability: ASME standards are widely used in the United States and North America, while ISO standards have a global reach and are recognized internationally.

3. Structure: ASME standards are often referred to as codes and are legally enforceable in many jurisdictions. On the other hand, ISO standards are generally voluntary and serve as guides for best practices.


In conclusion, while ASME and ISO both contribute to standardization and quality improvement, their areas of focus and reach differ. ASME sets industry-specific standards primarily in mechanical engineering, while ISO provides a more comprehensive range of standards applicable across industries worldwide. Understanding these organizations' roles and differences is vital for professionals seeking to adhere to relevant standards and ensure global compatibility in their respective fields.
