Performance testing

Proven performance, every single time.

In-house facilities

Every batch of Muirhead leather is tested in-house at our state-of-the-art material testing laboratory and R&D facility. We test to the individual customer’s specification, and supply a laboratory report ensuring that our product conforms exactly to their specification.

Pre-stressed testing

Most textiles testing carried out by other manufacturers is applied to new materials, which does not reflect real-world use. At Muirhead, we ‘pre-stress’ test samples by exposing them to extreme ranges of temperature and humidity to simulate years of real-world service and gather more realistic, useful data. Only then do we begin testing our leather’s performance.

Performance benchmarking

Continuous testing ensures that Muirhead leather delivers on its performance promises. We can benchmark against competitors and verify that leather aligns with specific needs. And we use internationally recognised methods in the aviation, passenger transport and furnishing industries.


Our laboratories are UKAS-accredited to EN 9100, ISO 9001, ISO 14001, ISO 50001, ISO/IEC 17025: IATF 16949 and OHS 45001. We are approved to carry out FAA 25.853, vertical burn and ABD0031 smoke density and toxicity testing and to test full seat constructions to EN45545-2 and EN16989. We have Marine Equipment Directive (MED) Approval and Vehicle Certification Authority (VCA) Type Approval. We also deliver industry-leading corrosion testing to ASTM 1611. All of that is in addition to strength, stretch, flexibility, rub and abrasion testing, and colour consistency, fastness and soil resistance.
