Smithers Rapra provide testing and consultative support for both civil and military aviation sectors. We offer testing for a range of international aerospace standards including SAE, RTCA, EUROCAE and EMAR.

Rubber and plastics used in aerospace applications see some of the most extreme conditions. From extreme high and low temperature conditions, to various fluid exposure and mechanical stresses, components and materials require significant testing and validation before they can be approved for use on aircraft. We provide support across many stages of the aerospace supply chain:

Aerospace engine

Material Testing

We offer a comprehensive range of testing services to international standards such as ISO, RTCA and SAE. Common tests our team perform include:

FEA Properties

Life Prediction Properties

Material Development Support

Fluid Susceptibility

(All properties are generated over the operating temperature range). 

Chemical Analysis

Whether working on the development of innovative new materials or benchmarking your competition, our chemistry team can provide analytical testing support, including materials identification, reverse engineering, contamination analysis and molecular weight characterisation.

Standard Testing

Our testing enables clients to ensure that their product, component or material meets the requirements specified in international or OEM standards. For the aerospace industry, we’re able to perform testing to the following standards: 



BS 4G 229:1996 /

ISO 7137:1995


Def Stan 00-35 part 3

BS 3G100: part 2: Section 3: 1991 subsection 3.12


BS EN 3909

Our expert team are also able to formulate bespoke test programmes which test properties which fall outside the parameters of standard test methods.

Accreditations and Specifications

Our global laboratories maintain accreditations from international standards bodies both for quality of work as well as to meet specific aerospace industry requirements. 

  • Our facilities are UKAS accredited to 17025 for the vast majority of the testing techniques we undertake.
  • Airbus Material Specification: Our experts undertake a variety of physical and chemical tests to fulfil the mandatory specifications set by Airbus (ARB).

  • GE Aviation S-450
