ASTM International offers resources for standards development and use worldwide according to individual country’s needs. 125 regional and national standards bodies partner with ASTM through its Memorandum of Understanding (MoU) program.

ASTM's physical and mechanical testing standards provide guides for the proper procedures employed in the determination of the physical, mechanical, and metallographic properties of certain materials, particularly metals and alloys.

An ASTM test method, as defined on p. iv, typically includes a concise description of an orderly procedure for determining a property or constituent of a material, an assembly of materials, or a product.

ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.

With our online standards platform ASTM Compass®, you can gain access to any of the over 12,000+ ASTM standards listed below, as well as standards from other international organizations such as AASHTO, AATCC, UNE AENOR, API, AWWA, CGA, IES, and UOP standards.

The ASTM publishes six types of standards: Test method; Specification; Classification; Practice; Guide; Terminology; ASTM test methods are definitive procedures that produce a result. They usually include a detailed description of a procedure for determining a property or constituent of a material, an assembly of materials, or a product.

2024年4月16日 · 1.2 The result obtained from this test method is dependent upon the behavior of the sample and is intended for application to liquids for which primarily the shear stress and shear rates are proportional (Newtonian flow behavior). If, however, the viscosity varies significantly with the rate of shear, different results may be obtained from viscometers of different capillary …

ASTM testing ensures product quality and safety by providing a standardized framework for evaluating materials, procedures, and performance. By following ASTM standards, manufacturers can ensure their products meet specific criteria and …

Comparing ASTM and ISO standards for material testing methods. Learn about their scope, development, recognition, and testing methodologies. Consider factors like industry requirements, geographic scope, testing capabilities, collaboration needs, and material/product requirements.

2019年8月1日 · Thermal conductivity measurements can be divided into two groups: steady state and transient state testing methods. Steady state methods also includes guarded hot-plate (GHP) method and Heat-Flow Meter (HFM), while a typical transient method is Laser/Xenon Flash (LFA/XFA) method. The figure below is the schematic view of the setup for GHP method.
