The rubber industry is one of many industries that trust ASTM testing, conducted by ASTM certified labs, to measure the safety and performance of their products and materials. ASTM test standards are developed by teams of experienced professionals and serve as industry benchmarks for quality.
What is ASTM Testing?
ASTM testing refers to a testing protocol determined by ASTM International, a worldwide leader in the development of voluntary consensus standards. ASTM International is comprised of over 30,000 members worldwide, all of whom contribute to the development of test methods and protocols. Each ASTM member brings valuable experience and perspective to the development process, ensuring a final standard that represents the needs of a given industry.
The history of ASTM International stretches back to 1898, when it was known as the American Society of the International Association for Testing of Materials. This organization was originally focused on assessing steel in the railroad industry in Pennsylvania.
Over a century later, ASTM International publishes testing standards for a wide range of industries and materials, including rubber, plastic, metals, textiles, electronics, and many more. Many ASTM standards are voluntary consensus, whereas others have been adopted as law.
An ASTM standard operates like a universal benchmark for quality and safety. Some ASTM standards have been adopted by government bodies, but most standards function as shared agreements. Virtually anyone in a given industry understands the value and importance of achieving compliance with a universal ASTM standard.
Every ASTM testing specification is designed to assess whether a material or product meets the appropriate performance and safety standards. But there’s an additional benefit to ASTM standards: credibility. A product that can demonstrate compliance with the appropriate ASTM standards is seen as more trustworthy than a competitor product that cannot.
Compliance to ASTM Methodology
Theoretically, any laboratory could buy a copy of an ASTM specification and carry out the testing protocol. But this approach is similar to trusting the average home cook to prepare a meal using recipes from a five-star restaurant’s head chef. Without the right training, practice, and equipment, the results simply will not be the same.
The purpose of the methodology compliance process is to ensure that the lab is delivering accurate, consistent testing data. If testing equipment is poorly calibrated or a technician is careless with a procedure, it can affect the results of the test. Inaccurate testing data is irresponsible at best and downright dangerous at worst. If inconsistent testing leads to inaccurate data, a material might get approved for use when, in reality, it doesn’t comply with safety or performance standards. This can lead to product failure. Depending on the context, someone could get hurt.
Compliance to ASTM methodology is accredited via ISO/IEC 17025. As part of this process, laboratories undergo a rigorous inspection and review process. The certification body will review pages upon pages of documentation and standard operating procedures. Auditors will stop by to assess every element of the lab in person, including testing equipment and safety procedures. Lab staff may be interviewed, as well. The process is intense, and the expectations are high.
Even after the accreditation process is complete, ISO/IEC 17025 certified labs are still required to comply with regular monitoring and check-ins with the accreditation body. This is to ensure that the lab continues to meet expectations for accreditation. If a lab loses focus and fails to meet expectations, they could lose their certification.
An ISO/IEC 17025 accredited lab is usually granted a scope of accreditation. The scope of accreditation is essentially a list of ASTM standards and other testing protocols that the lab is certified to perform on behalf of clients. If a client is seeking to demonstrate compliance with an ASTM standard, testing data from the lab is considered sufficient evidence for proving that all criteria are met.

Many ASTM testing standards can only be conducted using specific types of testing equipment, so the scope of accreditation will reflect the lab’s available testing technology. This is one of the great benefits of outsourcing ASTM testing to an accredited rubber testing laboratory: It saves you from having to buy your own testing equipment. Additionally, you can trust that all testing is being conducted by experienced testing professionals.
Types of ASTM Tests for Rubber
There are well over 100 active ASTM standards specific to the rubber industry. ASTM testings for rubber have many purposes, including:
- To observe the behavior of a rubber material under controlled conditions, such as a given temperature range. Examples include ASTM D1329, ASTM D573, and ASTM D395.
- To measure a rubber material’s resistance to different types of deterioration. Examples include ASTM D5963 and ASTM D624.
- To assess a rubber material’s resistance to various stressors and environmental rigors by isolating a single variable in a controlled environment. Examples include ASTM D1149 and ASTM C1166.
- To report the physical and chemical properties of a rubber material or product. Examples include ASTM D6204 and ASTM D1414.
- To observe the processability of a rubber material to predict behavior in a manufacturing environment. Examples include ASTM D2230 and ASTM D3182.
Some ASTM tests are designed to predict performance in extremely specific contexts, such as a tire tread on an icy road. Others are suited for more general assessments, such as a rubber material’s resistance to abrasion. An accredited lab can recommend the right suite of tests for your specific needs.
