The Standard Test Piece (STP) is the new standard for X-Ray penetration and image resolution testing set by the EU to replace the Combined Test Piece (CTP).
The Standard Test Piece is designed to ensure that the performance requirements for X-ray machines set out by the DETR are met and maintained.
It is manufactured to an exact specification and supplied ready for use in conjunction with the X-ray machine manufacturers' requirements.
The Standard Test Piece is manufactured to the U.K. Home Office, Department of Environment, Department for Transport and regional specifications, for use in support of the UK Transport Security Programme.
The STP unit also fully complies with regulations set by the European Civil Aviation Conference and can be used within European Union Countries.
In addition, a variant of the Standard Test Piece can be manufactured on special order for countries where the standards differ. The units comply fully with the requirements for the routine testing of X-ray screening equipment. The units weigh approx 4 kilos and are supplied inside a special black plastic attaché case.
