Performance Testing Summary

Termite resistance A new way of thinking about wood Accoya represents a revolution in modified wood, bringing new design possibilities for architects, manufacturers and property owners. The benefits of Accoya mean that timber projects can now be designed with absolute confidence. Accoya is a highly proven product with testing from many different perspectives, on a worldwide basis. Many tests have been conducted in real world conditions over many years. Accsys run an Approved Manufacturer Training Programme and we would encourage all manufacturers planning to use Accoya to contact their distributor...

2 DURABILITY THIS TEST WAS CONDUCTED BY: 5 year decay test 4 15 & 20 year canal lining test 6 5-year decay test Timber Products Inspection (USA), the largest accredited agency under ALSC for wood related auditing programs, have performed decay tests of Accoya wood at their Gainesville (Fl) exposure site. 5 year decay rating (E18 ground proximity) Testing was done over a 5 year field trial period according to AWPA E7-09 in ground stake test and AWPA E18-06 ground proximity test. The results show Accoya wood to outperform high quality (FEQ) teak, western red cedar and African mahogany. Radiata...

5 year decay test Durability and strength test 15 & 20 year canal lining test 20 year window L-joint test Termite resistance Durability and strength test Timber Products Inspection (USA) undertook a number of thorough and independent tests to analyse Accoya wood’s durability, stability and strength performance characteristics in accordance with the USA’s Window & Door Manufacturers Association (WDMA) requirements. Accoya wood outperformed Radiata Pine in accelerated decay chambers highlighting its durability. The results showed that Accoya wood had a very low weight loss percentage for both brown...

2 DURABILITY THIS TEST WAS CONDUCTED BY: 5 year decay test 4 15 & 20 year canal lining test 6 15 & 20 year canal lining test Accoya wood’s high performance was proven with two Dutch project tests in the Flevopolder near Almere, one installed in 1995 and one in 2000. The SHR institute in the Netherlands originally set up the tests and made detailed inspections at respective 15 and 20 year exposure periods in 2015. These tests include acetylated wood alongside control wood, preservative treated wood and hardwood species used as a canal lining (fresh water exposure). These canal bank conditions...

In durability field testing to European Norm (EN) 330:1993 - which parallels American Wood-Preserver's Association (AWPA) E9 - simple mortice and tenon joints (L-joints) are assembled, coated and placed outside, with the coating over the joint deliberately broken to allow...

Formosan termite test 8 5 year termite field test 9 Termite test, Australia 10 Termite test, Thailand 11 Formosan termite durability testLSU AgCenter’s Wood Durability Lab are a specialist in termite testing of wood products. Coptotermes formosanus, known as Formosan termites, are considered one of the world’s most aggressive termite species. Louisiana State University (LSU) conducted a Formosan termite ‘choice’ test according to AWPA E1-09 standard, using leached and unleached both treated (acetylated) and untreated samples together with choice samples. After 28 days of exposure, the samples...

Ground Proximity) The results were developed over a 5 year field trial period in accordance with AWPA E7-09 in ground stake test and AWPA E18-06 ground proximity test. Performance level...

3 TERMITE RESISTANCE THIS TEST WAS CONDUCTED BY: Formosan termite test 8 5 year termite field test 9 Termite test, Australia 10 Termite test, Thailand 11 Termite durability test, Australia - AFRC Coptotermes acinaciformis is a widely encountered species of Australian termite distributed throughout mainland Australia and is responsible for greater economic loss than all the other Australian species of termites combined. Hazard Class 3 above ground testing was set up in Northern Territory, Australia according to the AWPA protocol by the Australian Forest Research Company. At the conclusion of the...

3 TERMITE RESISTANCE THIS TEST WAS CONDUCTED BY: Formosan termite test 8 5 year termite field test 9 Termite attack and decay trial - Thailand Termite test, Australia 10 Termite test, Thailand 11 A test conducted by the Environmental Research Centre; Naresuan University involved setting up ground stake tests at sites around Thailand. Test stakes were Accoya, Teak and Makha. After 6 years Accoya demonstrated significantly higher performance than Makha hardwood and high-quality BurmeseTeak. This superior performance relative to Burmese Teak corroborates termite and decay evaluation tests reported...
