Testing services


TEMPEST test services

SST is a NCSC-accredited TEMPEST test house. (NCSC is the UK Government Technical Authority for information assurance.)
SST personnel have many years’ experience performing formal TEMPEST and EMC tests on fixed and mobile installations to military and UK Government test standards.

Offsite TEMPEST platform testing

SST is certified by NCSC to perform TEMPEST platform testing. With the benefit of many years platform testing experience SST either employ dedicated mobile test equipment on customer site or work conjunction with Trac (for EMC Testing) in the large shielded facility in Malvern.

Onsite TEMPEST product testing

SST TEMPEST and EMC Test Facility Personnel have many years experience performing acceptance testing on products and mobile platform installations. The NCSC accredited SST TEMPEST Test Facility has five TEMPEST test cells and is staffed by some of the most experienced NCSC trained Level 4 TEMPEST engineers in the UK.

SST will often work alongside equipment manufacturers to impart an appreciation of TEMPEST aspects during initial design stages. With a unique position in the UK, SST is a NCSC accredited manufacturer of TEMPEST products as well as providing the testing and endorsement function and has a deep appreciation of the manufacturing process, often providing an initial assessment of TEMPEST performance to highlight areas of concern before formal testing commences.

SST is able to offer a wide range of services including:

  • TEMPEST certification testing to NATO SDIP-27/2 Levels A, B and C (AMSG720B, AMSG788A and AMSG784B)
  • TEMPEST Production Assurance Testing (TPAT) to NATO SDIP-27/2 Levels A, B and C (AMSG720B, AMSG788A and AMSG784B)
  • EMC testing to MIL-STD-461 and DEF STAN 59-41
  • Endorsement to NATO standards through NCSC
  • TEMPEST/EMC design and consultancy services
  • Guidance on installation
  • On-site evaluations and investigations.

Compliance tests

As part of the testing procedure, SST can also provide clear and concise test plans, details of procedures and comprehensive reports.
SST can carry out a wide range of compliance tests including:

  • TEMPEST to AMSG 784B and 788A
  • DEF STAN 59-41
  • MIL STD 461
  • RTCA/DO160C/D

Platform testing

As a specialist TEMPEST test and certification company, SST has performed platform acceptance testing both in ‘green field’ situations and in the 18m x 14m TEMPEST and EMC test facility.

Electromagnetic fields in excess of 200V/m, 10kHz to 18GHz, can be also created to simulate very hostile environments.

TEMPEST facility (building) testing and installation

SST can assist when it comes to the requirements of TEMPEST Zoning (SDIP-28) and Installation (SDIP-29). SST can be involved from the initial discussion on whether TEMPEST should be taken into consideration, through Zoning Procedures, assessment of requirements, design of facility through to installation of services and equipment

In addition to SDIP-29 (Facility Design Criteria and Installation of Electrical Equipment for Processing Classified Information) SST includes the requirements of JSP440 and JSP480.

Testing facility

The UK test site is secure, enabling SST to cater for MoD and other defence contracts. The test facility measures 18 x 14 x 6 metres and has a 5 metre entrance to accommodate large wheel and track vehicles. It also has a reinforced floor to handle loads up to 80 tonnes. All the roadways on the site have been constructed for heavy machinery.

Approvals and accreditations

SST is NCSC registered and the TEMPEST test cells are approved by NCSC (the UK Government Technical Authority for information assurance).
