ASTM E136

ASTM E136 is the ASTM standard that describes a test method for assessing material combustibility using a vertical tube furnace at 750°C. It is used to evaluate how a material responds when exposed to controlled high heat, helping manufacturers, specifiers, and testing laboratories compare performance in a consistent way. Because combustibility data can influence material selection and compliance decisions, this standard is an important reference for products where fire-related behavior must be understood clearly and documented accurately.

Purpose of ASTM E136

The purpose of ASTM E136 is to provide a repeatable laboratory method for assessing whether a material is combustible under the specified furnace conditions. The vertical tube furnace setup at 750°C gives users a defined technical basis for testing and comparison, rather than relying on informal judgment. In practice, this helps support product evaluation, documentation, and conformity checks when combustibility is a relevant property. As an ASTM standard, it offers a common framework for consistent results across different labs and programs.

Common use cases of ASTM E136

ASTM E136 is commonly used when a material needs to be evaluated for combustibility as part of product development, qualification, or compliance testing. It is especially relevant for materials that may be incorporated into building products, assemblies, or other engineered applications where fire response matters. Laboratories may use it during incoming material review, certification work, or quality control programs. The standard helps teams apply a defined method when combustibility testing is needed for technical decision-making.

Why ASTM E136 matters

This standard matters because it supports consistent, defensible combustibility testing using a recognized furnace-based method. For procurement and quality control, that consistency helps reduce ambiguity when comparing materials or reviewing supplier data. For compliance workflows, ASTM E136 can help document performance using an established technical reference rather than an internal procedure. In short, it helps organizations make clearer material evaluations, improve repeatability, and support more reliable fire-related decision-making.
