Superconductivity - Electronic characteristic measurements. Intrinsic surface impedance of superconductor films at microwave frequencies1 Scope This part of IEC 61788 describes measurements of the intrinsic surface impedance (ZS) of HTS films at microwave frequencies by a modified two resonance mode dielectric resonator method [13, 14]2. The object of measurement is to obtain the temperature dependence of the intrinsic ZS at the resonant frequency f0. The frequency and thickness range and the measurement resolution for the intrinsic ZS of HTS films are as follows: frequency: up to 40

PD ISO/TR 23605:2009 Technical product specification (TPS)

BS EN IEC 62056‑8‑4 specifies DLMS/COSEM communication profiles for narrow-band OFDM power line carrier PRIME neighbourhood networks using the modulation as specified in recommendation ITU-T G

Introducing a client rather than a specifically asset oriented view

ISO/IEC TR 10037 on SGML Syntax-Directed Editing Systems is useful for:

that the product he receives conforms to specification

there may be more than one protocol (or set of related protocols starting) at layer (n) that can operate above layer (n − 1) in a given environment

Standard profiling systems exploit the non-coding regions of DNA that are referred to as “junk DNA”

BS EN 4173 provides a standardized approach for manufacturers of lockbolts to adhere to if they supply their components for use by the aerospace and defence industry
