Global brand for Non-destructive Testing (NDT) Training, Examination and Consultancy Services.

Here, he became involved in the X-ray examination of castings for aircraft. Later he joined the physics department where he worked on X-ray crystallography and microradiography.

Here Jack was introduced to the work which gave him the greatest personal satisfaction developing ultrasonic techniques for castings.

During his 20 years with BSCRA Jack made many contributions to the world of non-destructive testing in the form of lectures, papers and articles. He continued with research and he conducted training courses around the world. He was involved with Ron Halmshaw in early fluoroscopy and worked on the High Energy radiography of castings. He also patented a C-scan system. He contributed to committee work for British Standards, the International Institute of Welding and the City and Guilds of London Institute. He was a one-time secretary of SONDE, and on the Editorial Board of NDT International.

He was instrumental in establishing the SNT group under the British Institute of NDT following his organisation of an initial meeting in Sheffield with George Wheeler, a past President of ASNT in the early 1980s. Following on from these meetings, the ASNT North Atlantic Section was born in 1993 and Jack was one of its founder members.

The needs for high quality NDT training are, Jack always believed, best met by the SNT system of training and qualification. Consequently, he became its champion in the UK. Jack himself became one of the first ASNT Level 3s in 1977 (UT, MT, PT, RT, FA 726), a Member of the Institute of Physics, a Chartered Physicist, a Fellow of the Institute of Metallurgy and a Fellow of the British Institute of Non-destructive Testing. In 1991 he became a Fellow of the American Society of NDT and later in 1997 an Honorary Fellow of the British Institute.

The Lavender family decided that it was necessary to embrace this new programme of central certification and to reorganise the Company structure, so in 1985 the J.D Lavender Partnership became Lavender International NDT Consultancy Services Limited.

Since then Lavender International has established training centres in Houston, Texas, where we continue to offer the same quality of service that has come to be expected of the Lavender brand.
