IEC 61355

Last updated

The standard IEC 61355-1 Classification and designation of documents for plants, systems and equipment describes rules and guidelines for the uniform classification and identification of documents based on their characteristic content of information.

Contents

It is applied for all documents within the life cycle of a technical products like plants, systems or equipment. It also includes non-technical documents. The main application is the construction, erection and operation of chemical plants and power plants, where the number of documents may sum up to some 100,000 documents.

Classification code

The standard provides with the document kind classification code (DCC) a structured letter-code for the classification of any kind of document.

The document kind classification code consists of three code-letters A1, A2, A3, with the prefix "&".

The letter code A1 is optional, if all documents are from the same technical area. The letter codes A2 and A3 are identical for all technical areas.

Technical Areas

The technical areas are:

A1Technical area
AOverall management
BOverall technology
C Construction engineering
E Electrical engineering, instrumentation and control engineering
M Mechanical engineering (normally including process engineering))
P Process engineering (only if separation from M is required))

Classes

The main classes are:

A2document kind classes, main classes
ADocumentation describing documents
BManagement documents
CContractual and non-technical documents
DGeneral technical information documents
ETechnical requirement and dimensioning documents
FFunction describing documents
LLocation documents
MConnection describing documents
PObject listings
Q Quality management documents; safety-describing documents

ISO 216 is an international standard for paper sizes, used around the world except in North America and parts of Latin America. The standard defines the "A", "B" and "C" series of paper sizes, including A4, the most commonly available paper size worldwide. Two supplementary standards, ISO 217 and ISO 269, define related paper sizes; the ISO 269 "C" series is commonly listed alongside the A and B sizes.

The Great Britain road numbering scheme is a numbering scheme used to classify and identify all roads in Great Britain. Each road is given a single letter and a subsequent number. Though this scheme was introduced merely to simplify funding allocations, it soon became used on maps and as a method of navigation. There are two sub-schemes in use: one for motorways, and another for non-motorway roads.

The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water. It is published in the European Union by the European Committee for Electrotechnical Standardization (CENELEC) as EN 60529.

<span class="mw-page-title-main">Electrical equipment in hazardous areas</span> Electrical equipment in places where fire or explosion hazards may exist

In electrical and safety engineering, hazardous locations are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to electrical arcing, or high temperatures. Standards and regulations exist to identify such locations, classify the hazards, and design equipment for safe use in such locations.

IEC 61508 is an international standard published by the International Electrotechnical Commission (IEC) consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems. It is titled Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems.

The RKM code, also referred to as "letter and numeral code for resistance and capacitance values and tolerances", "letter and digit code for resistance and capacitance values and tolerances", or informally as "R notation" is a notation to specify resistor and capacitor values defined in the international standard IEC 60062 since 1952. Other standards including DIN 40825 (1973), BS 1852 (1975), IS 8186 (1976), and EN 60062 (1993) have also accepted it. The updated IEC 60062:2016, amended in 2019, comprises the most recent release of the standard.

The International Council on Large Electric Systems (CIGRE) is a global nonprofit organisation in the field of high voltage electricity. It was founded in Paris, France in 1921.

In electrical engineering, IEC 60269 is a set of technical standards for low-voltage power fuses. The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices. The IEC standard unifies several national standards, thereby improving the interchangeability of fuses in international trade. All fuses of different technologies tested to meet IEC standards will have similar time-current characteristics, which simplifies design and maintenance.

Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached. Technical standards for battery sizes and types are set by standards organizations such as International Electrotechnical Commission (IEC) and American National Standards Institute (ANSI). Popular sizes are still referred to by old standard or manufacturer designations, and some non-systematic designations have been included in current international standards due to wide use.

IEC 60870 part 5 is one of the IEC 60870 set of standards which define systems used for telecontrol in electrical engineering and power system automation applications. Part 5 provides a communication profile for sending basic telecontrol messages between two systems, which uses permanent directly connected data circuits between the systems. The IEC Technical Committee 57 have developed a protocol standard for telecontrol, teleprotection, and associated telecommunications for electric power systems. The result of this work is IEC 60870-5. Five documents specify the base IEC 60870-5:

A2 is an amputee sport classification used by the International Sports Organization for the Disabled (ISOD).for people with acquired or congenital amputations. A2 sportspeople have one leg amputated above the knee. Their amputations impact their sport performance, including having balance issues, increased energy costs, higher rates of oxygen consumption, and issues with their gait.

In patent law, a kind code, or WIPO Standard ST.16 code, is a code used on patent documents published by intellectual property offices to distinguish different kinds of patent documents. A kind code includes a letter, and in many cases a number, used to distinguish the kind of patent document and the level of publication. The recommended use is the two-letter country code followed by the patent document number and then the kind code, e.g., "US 7,654,321 B1" for U.S. Patent No. 7,654,321 where there was no previously-published patent application publication, and "US 2003/1234567 A1" for U.S. Patent Application Publication No. 2003/1234567, published in 2003.
