Is ASTM a code or standard?


What is ASTM?

ASTM, which stands for the American Society for Testing and Materials, is an internationally recognized organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Established in 1898, ASTM's mission is to enhance public safety, promote quality, and facilitate trade by providing technical standards that guide the design, manufacturing, and testing processes of various industries.

Throughout its history, ASTM has evolved from focusing solely on the steel industry to now covering more than 140 sectors, including construction, materials, metals, petroleum, medical devices, consumer products, and many others. The standards developed by ASTM are widely used and respected globally, serving as essential references for manufacturers, regulators, and consumers alike.

ASTM as a Standard

ASTM standards are often referred to as ASTM specifications or simply ASTM. These standards serve as a common language that enables manufacturers, purchasers, and end-users to communicate effectively regarding the characteristics, performance, and safety requirements of a product or material. ASTM standards are developed through a proven consensus process that involves collaboration among stakeholders, including industry experts, regulators, consumers, and academia.

It is important to note that ASTM standards are voluntary and not legally binding. However, they are widely adopted and incorporated into various regulations, contracts, and purchasing specifications worldwide. Manufacturers often use ASTM standards as benchmarks for quality assurance, compliance, and product development, while regulatory bodies frequently reference them to establish minimum safety requirements.

ASTM Codes

ASTM also develops codes in addition to their standards. ASTM codes are specifically tailored for particular industries or applications, providing comprehensive guidelines and requirements beyond the scope of individual standards. These codes are intended to promote best practices, ensure safety, and harmonize industry practices where necessary.

Unlike standards, ASTM codes often cover broader subject matters and may include multiple standards and technical publications. They serve as valuable references for engineers, designers, contractors, and other professionals involved in the construction, installation, and safety of various systems and structures.

Distinguishing Between ASTM Standards and ASTM Codes

While ASTM standards and codes are closely related, understanding the distinction between them is crucial. ASTM standards focus on specific materials, products, or test methods, providing technical specifications that are widely accepted and followed by industries. Codes, on the other hand, encompass a broader set of requirements, often encompassing several associated standards to cover comprehensive guidelines for specific applications.

For example, ASTM's A36 is a standard specification for carbon structural steel, providing the requirements for its chemical composition, mechanical properties, and other essential characteristics. In contrast, the ASTM AISC (American Institute of Steel Construction) Code combines multiple ASTM standards to provide detailed guidelines for the design, fabrication, and construction of steel structures.

Benefits and Importance of ASTM Standards

ASTM standards offer numerous benefits to manufacturers, consumers, and regulatory bodies. The following are some of the key advantages of using ASTM standards:

1. Elevated Quality:

ASTM standards ensure consistent and reliable quality across various industries, facilitating the manufacturing of safe, efficient, and high-performing products.

2. Improved Communication:

By having a common set of standards, ASTM facilitates effective communication between manufacturers, purchasers, and end-users, enabling better collaboration, understanding, and confidence in the products being traded.

3. Global Acceptance:

ASTM standards are recognized and respected worldwide, allowing easier access to international markets and facilitating global trade. This eliminates the need for manufacturers to meet different requirements for each market they wish to enter.

4. Regulatory Compliance:

Many regulatory bodies reference ASTM standards in their regulations, making it easier for manufacturers to demonstrate compliance with safety and performance requirements, reducing the need for additional testing and evaluation.

5. Technical Advancement:

ASTM continuously evolves its standards to keep pace with technological advancements, promoting innovation, and supporting industry growth.


ASTM plays a vital role in the development of technical standards and codes that impact numerous industries worldwide. With its comprehensive set of voluntary consensus standards, ASTM helps ensure the quality, safety, and performance of products, materials, and systems while facilitating international trade and regulatory compliance. By providing a platform for collaboration and knowledge sharing among diverse stakeholders, ASTM continues to drive innovation, improve consumer confidence, and enhance the overall efficiency of industries around the globe. Whether it's a standard or a code, ASTM's contributions to various sectors have a lasting impact on the way products are designed, manufactured, and tested for years to come.
