What is the difference between ASTM D and ASTM E?

 

ASTM standards are categorized into different sections based on the subject matter. Two commonly referenced sections are ASTM D and ASTM E. While both sections cover a wide range of standards, there are some key differences between them.

 

ASTM D Standards:

ASTM D standards primarily focus on materials and products related to engineering and industrial applications. These standards cover a broad range of topics, including but not limited to:

 

1. Plastics and Polymers: ASTM D standards provide guidelines for testing the physical, mechanical, and thermal properties of plastics and polymers. These standards help in assessing the quality, performance, and suitability of plastic materials for various applications.

 

2. Rubber: ASTM D standards address the testing and characterization of rubber materials, including elastomers, vulcanized rubber, and rubber products. These standards cover aspects such as tensile strength, hardness, aging properties, and chemical resistance.

 

3. Petroleum and Petrochemicals: ASTM D standards play a crucial role in the testing and analysis of petroleum products, lubricants, and fuels. These standards provide guidelines for evaluating properties such as viscosity, flash point, distillation characteristics, and oxidation stability.

 

4. Textiles: ASTM D standards cover the testing and evaluation of textile materials, including fibers, fabrics, and finished products. These standards address aspects such as tensile strength, tear resistance, colorfastness, and dimensional stability.

 

5. Construction Materials: ASTM D standards also encompass testing procedures for various construction materials, such as concrete, asphalt, paints, coatings, adhesives, and sealants. These standards help ensure the quality, durability, and performance of these materials in construction applications.

 

ASTM E Standards:

ASTM E standards, on the other hand, primarily focus on standards related to testing methods, practices, and terminology for various industries. These standards are more general in nature and cover a wide range of topics, including:

 

1. Testing Methods: ASTM E standards provide guidelines for conducting specific tests and measurements across different industries. These standards outline the procedures, equipment, and conditions required to perform accurate and reliable testing.

 

2. Calibration and Verification: ASTM E standards address the calibration and verification of instruments and equipment used for testing and measurement purposes. These standards ensure that the instruments are properly calibrated and provide accurate results.

 

3. Terminology and Definitions: ASTM E standards establish common terminology and definitions used in testing, measurement, and related fields. These standards help in promoting clear communication and understanding among professionals in different industries.

 

4. Statistical Analysis: ASTM E standards also cover statistical methods and techniques used for data analysis, interpretation, and quality control. These standards provide guidance on sampling, data presentation, regression analysis, and uncertainty estimation.

 

It's important to note that the above descriptions provide a general overview of the differences between ASTM D and ASTM E standards. The specific standards within each section may vary in their scope and application. To obtain detailed information about specific standards, it is recommended to refer to the ASTM website or consult the relevant standards directly.
