Ptest Laboratory tests products and materials. Our purpose built laboratory tests a diverse range of products and materials to a wide range of national and international standards, as well as customer determined specifications. Ptest is flexible enough to perform one off, non standard tests in support of research and development projects, as well as repetitive testing in support of continuing manufacture and supply.
Ptest staff are well qualified and highly experienced. Two of our IANZ approved signatories have been appointed as technical experts for International Accreditation New Zealand in the field of mechanical testing.
Ptest has no affiliation with any manufacturer or supplier so clients can be assured of unbiased testing and complete confidentiality.
