Entry (official wording)
Lead in micro-channel plates (MCPs) used in equipment where at least one of the following properties is present:
(a) a compact size of the detector for electrons or ions, where the space for the detector is limited to a maximum of 3 mm/MCP (detector thickness + space for installation of the MCP), a maximum of 6 mm in total, and an alternative design yielding more space for the detector is scientifically and technically impracticable;
(b) a two-dimensional spatial resolution for detecting electrons or ions, where at least one of the following applies:
(i) a response time shorter than 25 ns;
(ii) a sample detection area larger than 149 mm2;
(iii) a multiplication factor larger than 1,3 × 103.
(c) a response time shorter than 5 ns for detecting electrons or ions;
(d) a sample detection area larger than 314 mm2 for detecting electrons or ions;
(e) a multiplication factor larger than 4,0 × 107.
The exemption expires on the following dates:
(a) 21 July 2021 for medical devices and monitoring and control instruments;
(b) 21 July 2023 for in-vitro diagnostic medical devices;
(c) 21 July 2024 for industrial monitoring and control instruments.
