Holdstock Technical Services
Holdstock Technical Services was established on 1st November 2003 to provide technical services to the textile industry and other industries concerned with the understanding and control of static electricity.
Dr Paul Holdstock, the Managing Director and Sole Proprietor, graduated with Bachelor of Science Honours in Applied Physics and Computing Science from Manchester Polytechnic, England in 1987. He Joined Shirley Institute (now part of the British Textile Technology Group) as a research officer in the Electrostatics Laboratory. His research studies have included tribocharging of hospital bedding, development of electrically inert fabrics, ignition risks from textile materials (including apparel and industrial fabrics), evaluation of Eurofighter aircrew apparel and electronic damage caused by ESD from textiles. For the latter project he gained a PhD from Bolton Institute / University of Manchester.
Dr Holdstock is a Chartered Physicist and has been a member of the Dielectrics & Electrostatics Group at the Institute of Physics since 1988. He is Chairman of the BSI Technical Committee on Electrostatics (GEL/101) and of the IEC Electrostatics Technical Committee (TC101). His standards activities also include membership and convenorship of working groups and project teams in BSI, CEN, CENELEC, IEC and ISO.
Materials and product testing, from simple resistance measurements to more sophisticated qualification testing using state-of-the-art instrumentation. Laboratory testing is conducted under controlled temperature and humidity conditions. On-site testing is also available. Test methods used include ISO, IEC, CEN, BS, DIN, JIS, AATCC, ASTM and ANSI standards, and other specialised procedures. Here are just a few of the tests we can perform:
Charge decay measurements
Tribocharging tests (fabric samples)
Tribocharging tests (body voltage)
Electrostatic discharge behaviour (charge transfer measurements)
Corona onset voltage and corona current
Gas probe ignition tests
Many other electrosatic tests
Advice and guidance on the avoidance of hazards and problems associated with static electricity, choice of products and materials, product development, testing and certification.
Short training courses for individuals and small groups covering basic electrostatic theory, technologies for controlling static electricity, test methods, standards and codes of practice.
