International Organization For Standardization
The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and () it has published over 25,000 international standards covering almost all aspects of technology and manufacturing. It has over 800 technical committees (TCs) and subcommittees (SCs) to take care of standards development. The organization develops and publishes international standards in technical and nontechnical fields, including everything from manufactured products and technology to food safety, transport, IT, agriculture, and healthcare. More specialized topics like electrical and electronic engineering are instead handled by the International Electrotechnical Commission.Editors of Encyclopedia Britannica. 3 June 2021.Inte ...

Kappa Number
The Kappa number is an indication of the residual lignin content or bleachability of wood pulp by a standardized analysis method. Measuring method The Kappa number is determined by ISO 302:2004. ISO 302 is applicable to all kinds of chemical and semi-chemical pulps and gives a Kappa number in the range of 1–100. The Kappa number is a measurement of standard potassium permanganate solution that the pulp will consume. The measurement is inflated by the presence of hexenuronic acids in the pulp. These compounds are formed during the chemical pulping process, from the hemicelluloses. The Kappa number can be monitored by online Kappa analysers in a pulp mill, but these have to be calibrated with the ISO 302:2004 method. Application The Kappa number estimates the amount of chemicals required during bleaching of wood pulp to obtain a pulp with a given degree of whiteness. Since the amount of bleach needed is related to the lignin content of the pulp, the Kappa number can be u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ISO 269
An envelope is a common packaging item, usually made of thin, flat material. It is designed to contain a flat object, such as a letter (message), letter or Greeting card, card. Traditional envelopes are made from sheets of paper cut to one of three shapes: a rhombus, a short-arm cross or a Kite (geometry), kite. These shapes allow the envelope structure to be made by folding the sheet sides around a central rectangular area. In this manner, a rectangle-faced enclosure is formed with an arrangement of four flaps on the reverse side. Overview A folding sequence such that the last flap closed is on a short side is referred to in commercial envelope #Manufacture, manufacture as a pocket – a format frequently employed in the packaging of small quantities of seeds. Although in principle the flaps can be held in place by securing the topmost flap at a single point (for example with a wax seal), generally they are pasted or gummed together at the overlaps. They are most commonly u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 262
The ISO metric screw thread is the most commonly used type of general-purpose screw thread worldwide. They were one of the first international standards agreed when the International Organization for Standardization (ISO) was set up in 1947. The "M" designation for metric screws indicates the nominal outer diameter of the screw thread, in millimetres. This is also referred to as the "major" diameter in the information below. It indicates the diameter of smooth-walled hole that an externally threaded component (e.g. on a bolt) will pass through easily to connect to an internally threaded component (e.g. a nut) on the other side. For example, an M6 screw has a nominal outer diameter of 6 millimetres and will therefore be a well-located, co-axial fit in a hole drilled to 6 mm diameter. Basic profile The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its ...

ISO 259
ISO 259 is a series of international standards for the romanization of Hebrew characters into Latin characters, dating to 1984, with updated ISO 259-2 (a simplification, disregarding several vowel signs, 1994) and ISO 259-3 ( Phonemic Conversion, 1999). ISO 259 ISO 259, dating to the year 1984, is a transliteration of the Hebrew script, including the diacritical signs ('' niqqud'') used for Biblical Hebrew. The '' dagesh'' (dot inside the letter) is always transcribed with an overdot: ''ḃ'', ''ġ'', ''ż'', etc. The apostrophe () in the table above is the Hebrew sign '' geresh'' used after some letters to write down non-Hebrew sounds: , , , etc.. ISO 259-2 ISO 259-2 simplifies the diacritical signs for vowels of ISO 259, and is designed for Modern Hebrew. The '' dagesh'' is not transcribed excepted in the indicated cases. The apostrophe () in the table above is the Hebrew sign '' geresh'' used after some letters to write down non-He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 233
The international standard ISO 233 establishes a system for romanization of Arabic script. It was supplemented by ISO 233-2 in 1993 which is specific for Arabic language. 1984 edition The table below shows the consonants for the Arabic language. ISO 233-2:1993 ISO 233-2:1993 is an ISO schema for the simplified transliteration of Arabic characters into Roman characters and is dedicated to "Arabic language – Simplified transliteration". This transliteration system was adopted as an amendment to ISO 233:1984. It is used mainly in library context, and was introduced because ISO 233 was not meeting the indexing purposes, which are essential for the consistency of library catalogs. According to ISO 233-2(1993), Arabic words are vocalized prior to romanization. ISO 233-2 is used in French libraries and in North African libraries, and is recommended by ISSN An International Standard Serial Number (ISSN) is an eight-digit to uniquely identify a periodical publicati ...

ISO 228
British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread. It has been adopted as standard in plumbing and pipe fitting, except in North America, where NPT and related threads are used. Types Two types of threads are distinguished: * Parallel (straight) threads, ''British Standard Pipe Parallel thread'' (''BSPP''; originally also known as ''British Standard Pipe Fitting thread''/''BSPF'' and ''British Standard Pipe Mechanical thread''/''BSPM''), which have a constant diameter; denoted by the letter ''G''. * Taper threads, ''British Standard Pipe Taper thread'' (''BSPT''), whose diameter increases or decreases along the length of the thread; denoted by the letter ''R''. These can be combined into two types of joints: ; Jointing threads: These are pipe threads where pressure-tightness is made through t ...

Equal-loudness-level Contour
An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours. By definition, two sine waves of differing frequencies are said to have equal-loudness level measured in phons if they are perceived as equally loud by the average young person without significant hearing impairment. The Fletcher–Munson curves are one of many sets of equal-loudness contours for the human ear, determined experimentally by Harvey Fletcher and Wilden A. Munson, and reported in a 1933 paper entitled "Loudness, its definition, measurement and calculation" in the ''Journal of the Acoustical Society of America''. Fletcher–Munson curves have been superseded and incorporated into newer standards. The definitive curves are those defined in ISO 226 from the International Organ ...
