Pr Preliminary. Replaces standard from 2003). ![]() The established principles and methods are basic for all document management systems. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies where no requirements are specified. Parts 1 6: Building network protocol Network Protocols Implementation Application elements. Part 1: Vocabulary Terms relating to technical drawings, product definition and related products. Part 2: Vocabulary Terms relating to projection methods. The standard is under revision). The requirements apply to the HBES itself and its relations and interfaces with other systems and functions of buildings both inside and outside. This European Standard specifies the requirements for Intrusion and Hold-up Alarm Systems installed in buildings using specific or non-specific wired interconnections or wire-free interconnections. The electrical power installation includes, among others, the following equipment: rotating electrical machines; switchgear; transformers and reactors; converters; cables; wiring systems; batteries; capacitors; earthing systems; buildings and fences which are part of a closed electrical operating area; associated protection, control and auxiliary systems etc. The standard applies to the text of descriptions, drawings, markings, etc., in the elctrotechnical field and lays down a letter code for the designation of some distinct colour. ![]() Kodede grafiske Information technology Coded graphic character set for use in the preparation of documents used in electrotechnology and for information interchange. This part of IEC 60204 is applicable to the electrical equipment or parts of the electrical equipment that operate with nominal supply voltages not exceeding 1.000 V for alternating current (a.c.) and not exceeding 1.500 V for direct current (d.c.), and with nominal supply frequencies not exceeding 200 Hz. The standard lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low-voltage switchgear and controlgear assemblies. Standards Technical Drawing Series Covers GeneralThe series covers General rules Circuit-breakers Switches, disconnectors, switch-disconnectors and fuse-combination units Contactors and motor-starters Electromechanical contactors and motor-starters etc. IEC 81346, published jointly by IEC and ISO, establishes general principles for the structuring of systems including structuring of the information about systems. Based on these principles, rules and guidance are given for the formulation of unambiguous reference designations for objects in any system. ![]() A letter-code indicating the document kind class is provided together with rules and guidelines for its application in a document designation code. This standard is relevant for documents in all technical areas which are in use during the life cycle of a plant, system or equipment. This European Standard specifies the symbols and drawing rules for system flow diagrams and piping and instrument diagrams to be applied to refrigerating systems including heat pumps. Part 3: Detailed symbols for instruments interconnection diagrams. Part 4: Basic symbols for process computer, interface and shared displaycontrol functions. Graphical symbols for diagrams. Part 2: Symbol elements, qualifying symbols and other symbols having general application.
