4 Generic structure of DPLC and ADPLC terminals The generic structure describes the main building blocks of DPLC and ADPLC terminals. All other building blocks which are necessary for proper functioning (e.g. power supply, device control units) are not considered in Clause 4. Figure 2 shows the block diagram of a DPLC terminal with the digital and analog interfaces on the left side and the HF line interface on the right side. If only one interface is available, the function of the time division multiplexer / demultiplexer and optional Ethernet switch may be replaced by a simple direct connection to...11-29

IEC 62372-2021 pdf Nuclear instrumentation – Housed scintillators – Test methods of light output and intrinsic resolution
4 Test methods of basic parameters of housed scintillators 4.1 General 4.1.1 Test conditions Measurements shall be made under normal conditions, unless otherwise specified in the specifications of the manufacturer of housed scintillators. Measurements should start at least 0,5 h after the last device has been switched on, unless otherwise specified by the manufacturer specifications. Before measuring, the housed scintillator and the PMT is kept under high voltage for the time necessary for getting to the operation condition. Before measuring, the PMT is kept under high voltage for the time necessary for getting to the operation condition. All parameters are...11-29 -

1 Scope This part of IEC 62106 specifies the Radio Broadcast Data System (RBDS), which is an RDS- compatible variant used in countries of North America. RBDS was first standardized by the U.S. National Radio Systems Committee (NRSC) in 1993 and subsequently revised in 1998, 2004, 2005 and 2011 2 . With the publication of this edition of IEC 62106, the RDS and RBDS standards are now harmonized into a single document. The frequency range of operation (64,0 MHz to 108,0 MHz as indicated by the title of this document) varies according to regional regulatory authority. The U.S. range is...11-29

Criteria: After the test, there shall be no deformation of any of the components of the handle, mechanical lock, or key that affect form, fit, or function. Table 4 indicates the test procedures for typical handles. Different types of handles may require a different procedure for unlock, door open, door close, and/or lock operation. In such cases, the cycle test procedures should be modified according to the specific door operation. 5.2.4 Tests for panel strength Loads are intended to be applied from inside the cabinet in the direction indicated in Figure 4. If this is not practical then the panels...11-29
