ASTM E1559

ASTM E1559 is the standard that addresses contamination outgassing characteristics of spacecraft materials, helping users evaluate how materials may release contaminants in space environments. For spacecraft design, material selection, and qualification work, this type of test method is important because volatile emissions can affect nearby components, optical surfaces, and sensitive hardware. ASTM E1559 provides a technical basis for comparing materials under controlled conditions and supporting more consistent engineering decisions.

ASTM E1559 standard overview

ASTM E1559, Standard Test Method for Contamination Outgassing Characteristics of Spacecraft Materials, is intended to assess how materials behave when exposed to conditions relevant to outgassing evaluation. The standard is used as a technical reference for measuring contamination-related properties that may matter in spacecraft applications. By defining a common test approach, it supports more reliable comparison of candidate materials and helps align laboratory results with engineering and procurement needs.

Where is ASTM E1559 used?

This standard is commonly used in spacecraft materials evaluation, contamination control programs, and test laboratories supporting space hardware development. It may be applied when selecting or qualifying materials for parts, assemblies, coatings, adhesives, or other components that could contribute to outgassing concerns. ASTM E1559 is also useful in workflows where engineers need consistent data for comparing materials before they are incorporated into spacecraft systems or contamination-sensitive environments.

Practical importance of ASTM E1559

The practical value of ASTM E1559 is its role in reducing risk and improving consistency in material assessment. Outgassing data can support compliance efforts, internal specifications, and quality control decisions for spacecraft-related products. When teams use a recognized ASTM standard, procurement and testing discussions are easier to align, and material performance can be evaluated using a repeatable method. That helps support better documentation and more confident product selection.
