What are ASTM Standards

astm-international-vector-logo

In the world of product and material testing, a fundamental role is played by internationally recognized organizations that produce standards and related certifications.

Among the best known and most used are the ASTM Standards.

But what are ASTM standards? And why are they important?

The following article will take a detailed look at what ASTM Standards are.

History of ASTM Standards

 

The history of ASTM Standards dates back to the late nineteenth century, when a group of engineers and scientists led by Charles Benjamin Dudley, then head of quality control for the Pennsylvania Railroad, became aware of the increasingly frequent railway accidents related to the fragility of the tracks and proposed introducing precise quality standards that manufacturers would have to respect.

Thus, in 1902, the American Society for Testing and Materials, which changed its name in the 1960s, leaving only the acronym.

What are ASTM Standards

 

So, what are ASTM Standards today?

ASTM Standards today are technical specifications that establish criteria for the design, production, and evaluation of products and services. They provide clear and uniform guidelines to ensure consistency and regulatory compliance in industries worldwide. 

Almost all industries have to deal with ASTM Standards in one way or another.

Among those most affected by the ASTM guidelines we can include:

 

  • Building and Construction: ASTM Standards define specifications for construction materials, ensuring the safety and durability of buildings and infrastructure.
  • Manufacturing: In manufacturing processes, ASTM standards ensure product consistency and quality, improving efficiency and reducing errors.
  • Energy and Environment: Standards play a key role in regulating sustainable practices and assessing the environmental impact of industrial activities.
  • Materials Industry: ASTM standards address the characterization and evaluation of materials, ensuring their suitability for specific applications.
  • Product Safety: In industries such as electronics and apparel, ASTM standards help ensure consumer safety.

Climatic Testing in ASTM Standards

 

ASTM Standards outline a wide variety of tests that products and materials must pass to be considered safe and efficient. Many are physical, others chemical, and still others mechanical. A key role, however, is played by climatic tests that apply to virtually every product or material. 

Climatic tests simulate the effects of the environment on products and materials, both under normal and extreme conditions. Here, for example, we discussed accelerated aging testing in a climatic chamber, citing seven ASTM standards.

List of Major ASTM Standards by Industry

ASTM standards are organized into over 140 technical committees, each dedicated to a specific field. Here are the most relevant for climate and environmental testing:

StandardDescriptionSector
ASTM D4587Fluorescent UV exposure on paints and coatingsMaterials / Coatings
ASTM G154Exposure to fluorescent UV lamps for non-metallic materialsPlastics / Polymers
ASTM G155Exposure to xenon arc lampsPlastics / Fabrics
ASTM B117Salt spray testMetals / Corrosion
ASTM D1735Water spray test on coatingsConstruction / Cladding
ASTM E595Outgassing testing for aerospace materialsAerospace
ASTM D4459Sunlight exposure for plastics intended for indoor usePlastics

ASTM vs. ISO: When to Use Which

A common question is: when should ASTM standards be used and when should ISO standards be used? The choice depends primarily on the target market and regulatory requirements:

  • North American Market: ASTM standards are generally preferred and often required by law in the United States and Canada
  • European and international market: ISO and EN standards prevail
  • Global scope: Many industries accept both. In some cases, equivalent standards exist (e.g., ASTM D4329 and ISO 4892 for UV testing).

It's important to note that ASTM and ISO often cover the same tests with similar methodologies. For example, for UV testing of plastics, both ASTM G154 and ISO 4892 require the use of fluorescent UV lamps with comparable parameters.

How ASTM Numbering Works

Each ASTM standard follows a precise numbering system:

  • The initial letter indicates the technical committee: A (ferrous materials), B (non-ferrous materials), C (cement and concrete), D (miscellaneous materials), E (analytical methods), G (corrosion and degradation)
  • The number identifies the specific standard
  • Theyear after the dash indicates the latest revision (e.g. ASTM B117-19 = 2019 revision)

Frequently Asked Questions about ASTM Standards

What does ASTM mean?

ASTM stands for American Society for Testing and Materials. Today, the organization officially uses the name ASTM International to reflect its global role in standardization.

Are ASTM standards recognized in Europe?

Yes, ASTM standards are recognized and used worldwide, although in Europe, EN and ISO standards generally take regulatory precedence. Many European companies exporting to the US are still required to comply with ASTM standards.

What is the difference between ASTM and ISO?

The main difference isgeographic origin and scope: ASTM was born as an American standard (later international), while ISO was born as an international organization. Both produce high-quality standards, and equivalent or harmonized standards exist in many sectors.

How are ASTM tests performed in a climatic chamber?

Most ASTM climate tests require a climate chamber capable of precisely controlling temperature, relative humidity, and, in some cases, UV radiation. FDM climate chambers are designed to meet all these requirements.
