IDEST are a certification body accredited to ISO/IEC 17024:2012 to provide certification of persons.
During the 1970s and 80s it was seen that diving cylinders were not being tested and it was realised that there was the possibility that divers, and more probably the cylinder fillers, could be injured or killed.
Mike Todd and a group of other prominent divers who shared the same concerns, formed the Inspectorate for Diving Equipment Servicing & Testing in 1985 with the aim of improving diver safety through cylinder testing. However, it was discovered that some test centres were not testing cylinders properly. In fact, in some cases, the cylinders were cursorily looked at and stamped with no checking of cylinder condition or valve thread form.
It soon became obvious that more people were needed to inspect the growing number of Test Centres that wanted IDEST certification.
Because of the increase in the number of certified Test Centres, IDEST now has approved inspectors that cover the entire country and some overseas locations.
Technicians are currently assessed in their work place, together with an examination of the relevant documentation. The necessity for certain types of equipment means that Test Centre facilities are assessed at the same time as the Technicians, for suitability.
All procedures must follow a Code of Practice and IDEST CP11:2022 is used as that standard. This IDEST website shows a list of certified Test Centres, their contact details, email and website addresses.
IDEST produces a series of Technical Information Sheets and these are available on request from the Administration Office or are downloadable from this IDEST website. They cover a variety of topics including PPE, calibration sheets, O2 cleaning of diving cylinders, thread gauges classes, etc. Any time advice and guidance is sought, an email or telephone call will bring a quick response.
An extensive assessment is made by UKAS each year and IDEST is further accredited for this current year to ISO/IEC 17024:2012. Details may be gained from the UKAS website – Certification Bodies / 0248

Dave took over the role of Chairman from Neil Minto on 1st December 2021. Dave comes from a background of building and civil engineering but has had a diving interest since his first dives in Cyprus in 1961-64.

He was regularly used as a test dive subject at DDRC in the 1980s and in 1990 took on the engineering at DDRC until 2000. His interest in technical diving was initiated by the embryonic re-breather testing to 200m+ that he undertook at DDRC for Carmellan Research. He ran Technical Diving International (TDI) in Europe and later joined Professional Scuba Association (PSAI) managing UK and Scandinavia.
