EN 16603-32-08:2016 - Overview
EN 16603-32-08:2016 (derived from ECSS‑E‑ST‑32‑08) is the CEN European standard for space engineering - materials. It specifies mechanical engineering requirements and verification methods for materials used in space applications, including the mechanical effects of natural and induced space environments. The standard covers establishment of mechanical and physical properties and the verification of those properties using destructive and non‑destructive testing. Quality assurance for materials procurement and control is handled by ECSS‑Q‑ST‑70, and the standard may be tailored to project constraints per ECSS‑S‑ST‑00.
Key topics and technical requirements
- Material review and governance: Materials for space structures shall be reviewed by a Materials, Mechanical Parts and Processes Control Board (MPCB).
- Strength and load cases: Material strength must be established for the worst realistic combinations of mechanical and thermal loading over the item lifetime.
- Elastic modulus: For composites, Young’s modulus (tension/compression) must be verified by representative tests; metallic values may be manufacturer‑certified.
- Fatigue and fracture toughness: Components exposed to alternating stresses require demonstration that property degradation stays within limits for the mission. Fracture toughness (Kic, Kiscc) shall be measured per customer‑approved procedures, particularly for metals in corrosive environments.
- Creep and micro‑yielding: Risk analyses are required; where creep or micro‑yielding is predicted, dedicated test campaigns or dimensional‑stability tests must be performed.
- Thermal and moisture stability: Projects must define coefficients of thermal expansion (CTE) and moisture expansion (CME) for high‑stability applications; CTE/CME measurement and sensitivity analyses (including manufacturing variability) are mandated for composites and hygroscopic materials.
- Interfaces, coatings and joining: Requirements cover anodizing, chemical conversions, metallic and hard coatings, moisture/thermal barriers, coatings on CFRP, organic paints, bolted and riveted joints, and inserts.
- Verification and inspection: Verification includes destructive testing, non‑destructive inspection (NDT/NDE/NDI) and data exchange requirements; personnel qualification references (e.g., EN 4179) apply.
Practical applications and users
This standard is targeted at:
- Space system engineers and structural/materials engineers designing spacecraft structures and components
- Materials suppliers and manufacturers providing metals, composites (CFRP, MMC, CMC), coatings and fasteners for space projects
- Test laboratories performing mechanical, environmental, fracture‑mechanics and NDT services for space hardware
- Project quality and assurance managers who must ensure compliance, procurement control and MPCB reviews
Typical applications include selection and verification of structural materials, design allowables derivation, fatigue/fracture testing programs, thermal/moisture stability assessments, and qualification of coatings and joining methods for launch and orbital environments.

NOTE
This clause covers only structural subjects affecting materials for use in space projects. 4.2 Functionality 4.2.1 Strength a. The material strength shall be established for the worst combination of mechanical and thermal effects expected during its lifetime. NOTE
The strength of a material is highly dependent on the direction as well as on the sign of the applied load, e.g. axial tensile, transverse compressive, and others. Structural subjects are covered in ECSS-E-ST-32. 4.2.2 Elastic modulus a. For composites, the specified elastic modulus shall be verified by test on representative samples, in tension and in compression directions. NOTE 1 For metallic and alloy, it can be based on values certified by the manufacturer. NOTE 2 The elastic modulus defined as the ratio between the uniaxial stress and the strain (e.g. Young’s modulus, compressive modulus, shear modulus) is for metals and alloys weakly dependant on heat-treatment and orientation. However, for fibre reinforced materials, the elastic modulus depends on the fibre orientation. SIST EN 16603-32-08:2016
Fatigue fracture can form in components which are subjected to alternating stresses. These stresses can exist far below the allowed static strength of the material. For fracture control, see ECSS-E-ST-32-01. 4.2.4 Fracture toughness a. For homogeneous materials the Kic or Kiscc shall be measured according to procedures approved by the customer at MPCB. b. Metallic materials intended for use in corrosive surface environments shall be tested for fracture. NOTE
The fracture toughness is a measure of the damage tolerance of a material containing initial flaws or cracks. The fracture toughness in metallic materials is described by the plain strain value of the critical stress intensity factor. The fracture toughness depends on the environment. For fracture control, see ECSS-E-ST-32-01. 4.2.5 Creep a. A risk analysis shall be performed to assess the risk of creeping. b. If analysis specified in 4.2.5a confirms that creep can occur, the creep testing campaign to be performed shall be agreed with the customer at MPCB. NOTE
Creep is a time-dependant deformation of a material under an applied load. It usually occurs at elevated temperature, although some materials creep at room temperature. If permitted to continue indefinitely, creep terminates in rupture. Extrapolations from simple to complex stress-temperature time conditions are difficult. 4.2.6 Micro-yielding a. A risk analysis shall be performed to assess the risk of micro-yielding. N
