Accreditation to ISO 14644-1 Level 5

To further improve the suitablility of the Melaphone products within the exacting standards required in the cleanroom and food hygiene industries, we subjected our Melaphones to some rigorous tests. We worked closely with Cleanroom Consulting Ltd, experts in cleanroom project management and design, who organised the independent tests and certification to the ISO14644-1 standards.

We believe that our product is the only non-electrical window aperture fitting speaking device of its kind and design that meets this high standard. In fact, the tests exceeded our original expectations and achieved Level 5. The device was deemed suitable for use as an audio visual aid in cleanrooms up to ISO14644-1 ISO 5 Level as they maintain a high positive and negative pressure barrier and do not increase or generate particle at rest or in operation.

We are extremely pleased with these results and will look to build on this success over the coming months. A copy of the certificate is available to download here and the actual testing footage can be viewed here
