ANSI vs ASTM: What’s the Difference

The roles of ANSI and ASTM standards are crucial in ensuring safety and quality across various industries. Understanding the differences between ANSI and ASTM standards is essential for professionals involved in product development and safety compliance. 

The ANSI (American National Standards Institute) oversees standards and conformity assessment activities in the United States. While, ASTM International develops and publishes technical standards for industries including iron and steel, metal, construction, rubber, petroleum, textiles, plastics, medical device and services, and more. 

In this article, we’ll explain ASTM vs ANSI and clarify their differences.

What is ANSI?

ANSI is the abbreviation for the American National Standards Institute. ANSI is a non-profit, private organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. It also coordinates U.S. standards with international standards to help ensure global market compatibility.

ANSI does not develop standards itself. Instead, it provides a framework that supports fair standards development and robust conformity assessment systems, ensuring their integrity over time. ANSI works closely with government bodies and experts within their industry field to collaborate and assist in developing regulations based on international and regional needs.

ANSI's Essential Requirements: Due process requirements for American National Standards are a set of provisions designed to ensure that the development of American National Standards is a fair and responsive process that is open to all directly and materially interested parties.

What is ASTM?

ASTM stands for ASTM International (formerly the American Society for Testing and Materials). Formed in 1898, ASTM is a not-for-profit global leader in the development and delivery of voluntary consensus standards.  

It is a globally recognized organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. More than 13,000 ASTM standards are used worldwide to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

Who develops ASTM standards?

ASTM standards are developed and published by the American Society for Testing and Materials (ASTM).

Key Functions of ASTM

Developing Standards for Materials, Products, Systems, and Services

One of ASTM’s core missions is to create standards that define the specifications for a wide variety of products, materials, systems, and services. These standards serve as benchmarks to ensure that products meet specific performance criteria. Whether it’s the testing of construction materials, the specifications for a certain type of plastic, or guidelines for laboratory practices, ASTM has the expertise and resources to develop precise and actionable standards that meet industry needs.

For example, ASTM developed the standard ASTM A36, which sets the guidelines for carbon steel used in structural applications. The standard ensures that the material has the necessary strength and durability for use in construction projects, where reliability is critical for safety.

Collaboration with Industry Experts and Global Stakeholders

ASTM recognizes that no single organization can develop standards in isolation. That’s why it collaborates extensively with industry experts, government agencies, and global stakeholders to develop comprehensive standards. These collaborations ensure that standards are not only practical and scientifically grounded but also align with global needs and innovations.

ASTM committees include representatives from various sectors, including manufacturers, regulators, academics, and even environmental advocates. This collaborative approach ensures that the standards developed are balanced, relevant, and applicable across different markets.

Promoting Standards Domestically and Globally

Although ASTM originated as an American institution, its influence is global. ASTM standards are often recognized and adopted internationally, playing a critical role in facilitating global trade and ensuring the safety and reliability of products across borders. For instance, ASTM standards are frequently used in the oil and gas industry, which operates globally and requires standardized materials and practices to ensure consistency and safety across all regions.

Additionally, ASTM is actively involved in international standardization efforts and works closely with organizations like ISO to align its standards with global benchmarks.

Examples of ASTM standards

Here are some examples of ASTM standards:

ASTM F2236: Safety Standard for Soft Infant and Toddler Carriers

ASTM F963- Safety Standard for Toys in the US

Are ASTM standards mandatory?

ASTM standards are generally voluntary. That being said, some are incorporated by reference in US product regulations, which thus makes them mandatory.

Which products must comply with ASTM standards?

Products subject to US regulations that incorporate ASTM standards by reference must comply with those ASTM standards. For example, toys sold in the United States must comply with ASTM F963 as this is mandated by Part 1250.

Are ASTM standards recognized in the United States?

Standards developed by ASTM are generally accepted by US businesses and government agencies. This makes sense as the ASTM cooperates with US businesses and other American organizations in developing standards.

Are ASTM standards recognized in the EU or UK?

ASTM standards are generally not recognized by the European Union and the United Kingdom. For example, toys sold in the EU and the UK must comply with EN 71 standards. Compliance with the US equivalent, ASTM F963, is normally not accepted as a replacement.

That being said, the EU General Product Safety Regulation states that international standards can be used when there are no European standards available for a certain product or risk factor. In such situations, an ASTM standard may be the only option.

What is the Difference Between ANSI and ASTM?

Here’s a clear comparison of the differences between ANSI and ASTM:

The main difference between ASNI and ASTM is that ANSI is focused primarily on voluntary guidance on processes and is an umbrella organization that covers several industries in which they accredit other organizations to do so and approve the standards they develop (including the ASTM).

On the other hand, ASTM is more active in creating and enforcing standards that the ASNI approves. Therefore, they work closely together in designing and governance new measures which must be conformed to.

Which Standards Should Your Industry Follow?

Choosing the right standard—whether ANSI or ASTM—depends on the specific needs of your industry. Different sectors require different standards for different purposes. In this section, we’ll explore which industries generally favor ANSI standards versus those that rely more heavily on ASTM standards.

Industries That Prefer ANSI Standards

Certain industries lean more heavily on ANSI standards due to their broader scope and emphasis on processes and general safety. These industries include:

Technology and Telecommunications

In sectors like telecommunications and information technology, ANSI plays a significant role in setting standards that ensure compatibility, interoperability, and security. For example, ANSI standards define technical specifications for network equipment, data security protocols, and even the processes for managing information systems.

Safety Compliance

ANSI’s role in workplace safety and hazard management is also well-recognized. Standards such as ANSI Z87.1, which covers the safety requirements for eye protection, are commonly referenced in industries where personal safety is of paramount importance. ANSI standards in this space help ensure the safety of workers in various industries, including construction, manufacturing, and healthcare.

Industries That Rely on ASTM Standards

On the other hand, industries that involve materials testing, product performance, and manufacturing often prefer ASTM standards due to their technical nature and emphasis on testing methods and material properties. These industries include:

Construction and Manufacturing

In construction, engineering, and material manufacturing, ASTM standards are widely adopted because they offer the specific performance and testing specifications needed for materials used in construction, machinery, and other infrastructure projects. ASTM A36, for example, is a standard that covers steel specifications for use in structural applications.

Material Testing and Product Development

For industries engaged in research and development, especially when it comes to testing new materials or products, ASTM standards offer the technical guidelines needed for proper material characterization, performance testing, and product evaluation. ASTM’s standards for plastics, metals, and composite materials are critical for companies that are developing innovative materials for a variety of sectors.

Choosing the Right Standard for Your Needs

The decision of whether to follow ANSI or ASTM standards depends largely on the specific needs of your industry. If your business is focused on general safety, workplace processes, and regulatory compliance, you’ll likely find that ANSI standards are more suitable. On the other hand, if your work involves the testing, quality control, and performance evaluation of materials, ASTM standards are likely to be a better fit.

Benefits of ANSI vs. ASTM in Different Contexts

• ANSI standards are generally more focused on ensuring that an organization’s processes are safe, efficient, and reliable. These standards help businesses operate in compliance with national regulations and maintain consistency.
• ASTM standards, by contrast, provide the technical guidelines that ensure the performance and quality of specific materials or products. These standards are often more detailed and are used by professionals in fields such as engineering, construction, and materials science.

Conclusion

The American National Standards Institute (ANSI) and ASTM International play a crucial role in setting quality standards across different sectors. ANSI is responsible for creating agreed-upon guidelines that guarantee the security and dependability of goods and services. In contrast, ASTM concentrates on developing voluntary consensus guidelines that encompass materials, products, systems, and services.
