What is ASTM D2000?
ASTM D2000 is a standard that helps classify and specify rubber materials based on their performance properties, such as durability, hardness, and resistance to heat or chemicals. This standard ensures that the right type of rubber is used for specific applications, particularly in industries like automotive and aerospace.
The ASTM long form stands for the American Society for Testing and Materials, an organization that develops global standards. ASTM D2000 is part of the ASTM D series, which focuses on ensuring that rubber materials meet the necessary requirements for quality and reliability in various industries.
ASTM Specifications and Their Importance
ASTM specifications are guidelines that ensure rubber products meet certain quality and performance standards. These specifications help manufacturers maintain consistency in the materials used across different applications. For example, correct O-ring sizing is critical in many applications. Learn more about the various size standards in our article on O-Ring Size Standards & International Size Charts.
Following material standards ASTM is essential for ensuring that products are reliable and perform as expected, especially in industries like automotive and aerospace, where precision is key.
The term IAW spec (In Accordance With Specification) means that the product adheres to the specific requirements set by standards like ASTM D2000, ensuring the rubber materials meet the necessary performance criteria.
Understanding Material Classification in ASTM D2000
Material Grade, Type, and Class
In ASTM D2000, rubber materials are classified by grade, type, and class, which define their performance characteristics and suitability for specific applications. These details are outlined in the material spec sheet to help users select the appropriate material.
Here’s an example breakdown:
| Grade | Type | Class | Description |
| M1 | A | 1 | High-temperature-resistant rubber |
| M2 | B | 3 | Low-temperature-resistant rubber |
| M3 | C | 5 | Oil-resistant rubber |
- Grade: Represents the material’s quality and performance level.
- Type: Defines the rubber’s resistance to heat and fluids.
- Class: Refers to material properties like tensile strength and hardness.
Durometer and Tensile Strength
In ASTM D2000, both durometer (hardness) and tensile strength are critical properties used to classify rubber materials. These characteristics help ensure that the material can withstand the specific demands of its intended application, such as resistance to deformation or breaking under stress.
| Durometer (Hardness) | Tensile Strength (MPa) |
| 50-60 Shore A | 10-12 |
| 60-70 Shore A | 12-15 |
| 70-80 Shore A | 15-18 |
- Durometer: Measures the hardness of the rubber. A higher Shore A number indicates a harder material.
- Tensile Strength: This represents the maximum stress the rubber can withstand before breaking, measured in megapascals (MPa).
These properties are crucial in the specification of rubber products because they determine the material’s durability and resistance to wear, compression, and environmental factors. Selecting the right durometer and tensile strength ensures that the rubber performs reliably under specific conditions.

How to Read an ASTM D2000 Specification?
Reading an ASTM D2000 specification involves understanding the key components in the code, which describe the material’s performance characteristics.
- Type and Grade: The first part of the specification code indicates the type (resistance to heat, fluids, etc.) and the grade (performance level) of the rubber.
- Durometer and Tensile Strength: The numbers that follow describe the material’s durometer (hardness, measured in Shore A) and tensile strength (measured in MPa).
- Suffixes: Letters and numbers at the end of the code indicate additional properties, such as resistance to oils or other environmental factors.
| Example Code | Meaning |
| M2BG714B14 | Type 2, Grade B, Durometer 70, Tensile Strength 14 MPa |
| EO14 | Oil-resistant suffix |
| EO34 | Additional suffix for oil-resistant materials |
Spec’d Meaning
The term spec’d refers to a material being specified to meet the requirements set in ASTM D2000. This ensures that the product performs as expected under certain conditions.
Importance of the Material Spec Sheet
The material spec sheet is crucial for understanding all the details of the ASTM specification. It provides complete information about the rubber material’s properties, ensuring the correct material is chosen for specific applications, in line with ASTM D2000 standards.
Special Requirements and Suffixes in ASTM D2000
In ASTM D2000, suffixes indicate special requirements such as resistance to heat, oils, or fuels. These suffixes are listed at the end of the material’s specification code on the material spec sheet, helping users identify key performance properties. For example, EPDM rubber is widely used for its superior resistance to various environmental factors. Learn more in our article on EPDM Rubber: Meaning, Benefits, Applications.
Common Suffixes and Their Meanings
| Suffix | Meaning |
| A | Heat resistance |
| B | Low-temperature resistance |
| EO | Oil resistance |
| F | Fuel resistance |
These suffixes ensure that the specification rubber meets the required ASTM D2000 standards for specific applications.
ASTM D2000 in Different Types of Industries
ASTM D2000 is applied across various industries to ensure rubber materials meet specific standards for performance and safety.
- Automotive Industry
