ISO 7 PIPE THREADS WHERE PRESSURE-TIGHT JOINTS ARE MADE ON THE THREADS

Related standards ISO 6:1993 (first published in 1974) and ISO 2240:2003[16] (first published in July 1982, revised in September 1994, and corrected in October 2003) define scales for speeds of black-and-white negative film and color reversal film, respectively.

The determination of ISO speeds with digital still-cameras is described in ISO 12232:2006 (first published in August 1998, revised in April 2006, and corrected in October 2006).

The ISO system defines both an arithmetic and a logarithmic scale. The arithmetic ISO scale corresponds to the arithmetic ASA system, where a doubling of film sensitivity is represented by a doubling of the numerical film speed value. In the logarithmic ISO scale, which corresponds to the DIN scale, adding 3° to the numerical value constitutes a doubling of sensitivity. For example, a film rated ISO 200/24° is twice as sensitive as one rated ISO 100/21°.

Commonly, the logarithmic speed is omitted; for example, "ISO 100" denotes "ISO 100/21°", while logarithmic ISO speeds are written as "ISO 21°" as per the standard.

ISO 4 (INFORMATION AND DOCUMENTATION) – RULES FOR THE ABBREVIATION OF TITLE WORDS AND TITLES OF PUBLICATIONS

ISO 4 (Information and documentation – Rules for the abbreviation of title words and titles of publications) is an international standard which defines a uniform system for the abbreviation of serial titles, i.e., titles of publications such as scientific journals that are published in regular installments.

The ISSN International Centre, which the International Organization for Standardization (ISO) has appointed as the registration authority for ISO 4, maintains the "List of Title Word Abbreviations" (LTWA) which contains standard abbreviations for words commonly found in serial titles. As of August 2017, the standard's most recent update came in 1997, when its third edition was released.

A major use of ISO 4 is to abbreviate the names of scientific journals using the List of Title Word Abbreviations (LTWA). For instance, under ISO 4 standards, the Journal of Biological Chemistry is cited as J. Biol. Chem. and the Journal of Polymer Science Part A should be cited as J. Polym. Sci. A (capitalization is not specified by the standard). The standard notes that "Full stops shall only be used to indicate an abbreviation. Full stops may be omitted from abbreviated words in applications that require limited use of punctuation".

ISO 3:1973 PREFERRED NUMBERS – SERIES OF PREFERRED NUMBERS

Renard series is a system of preferred numbers dividing an interval from 1 to 10 into 5, 10, 20, or 40 steps. This set of preferred numbers was proposed in 1877 by French army engineer Colonel Charles Renard. His system was adopted by the ISO in 1949 to form the ISO recommendation R3, first published in 1953 or 1954, which evolved into the international standard ISO 3. Renard's system of preferred numbers divides the interval from 1 to 10 into 5, 10, 20, or 40 steps. The factor between two consecutive numbers in a Renard series is approximately constant (before rounding), namely the 5th, 10th, 20th, or 40th root of 10 (approximately 1.58, 1.26, 1.12, and 1.06, respectively), which leads to a geometric sequence. This way, the maximum relative error is minimized if an arbitrary number is replaced by the nearest Renard number multiplied by the appropriate power of 10. One application of the Renard series of numbers is to the current rating of electric fuses.

The most basic R5 series consists of these five rounded numbers, which are powers of the fifth the root of 10, rounded to two digits. Note that the Renard numbers are not always rounded to the closest three-digit number to the theoretical geometric sequence:

R5: 1.00 1.60 2.50 4.00 6.30

ISO 2:1973 TEXTILES (DESIGNATION OF THE DIRECTION OF TWIST IN YARNS AND RELATED PRODUCTS)

ISO 2 is an International Standard for direction of twist designation for yarns, complex yarns, slivers, slubbings, rovings, cordage and related products.

The standard uses capital letters S and Z to indicate the direction of twist, as suggested by the direction of slant of the central portions of these two letters. The handedness of the twist is the direction of the twists as they progress away from an observer. Thus, Z-twist is said to be right-handed and S-twist to be left-handed. The convention of using these two letters to unambiguously designate twist direction was already used in the cordage industry by 1957.

ISO 1:2016 - GEOMETRICAL PRODUCT SPECIFICATIONS (GPS)

ISO 1:2016 is an international standard set by the International Organization for Standardization (ISO) that specifies the standard reference temperature for geometrical product specification and verification. The temperature is fixed at 20°C, which is equal to 293.15 kelvins and 68 degrees Fahrenheit.

Due to thermal expansion, precision length measurements need to be made at a defined temperature. ISO 1 helps in comparing measurements by defining such a reference temperature. The reference temperature of 20 °C was adopted by the CIPM on 15 April 1931 and became ISO recommendation number 1 in 1951. It soon replaced worldwide other reference temperatures for length measurements that manufacturers of precision equipment had used before including 0 °C, 62 °F and 25 °C. Among the reasons for choosing 20 °C was that this was a comfortable and practical workshop temperature and that it resulted in an integer value on both the Celsius and Fahrenheit scales.

DIRECTORY OF ISO REGISTRARS OR CERTIFICATION BODIES

A Certification body is nothing but a registrar that is competent and authorised to issue Certification on Management System after successful completion of the Management System Audit.

There are few criteria’s which distinguish the ISO registers from one another:

1) 100% success rate on Project Completion- They should be having 100% success rate on project completion with full efficiency. To deliver project on time you need people who are disciplined and punctual, also having a high standard of understanding of the management systems. 

2) Competent Auditors within the organization- They should be having competent auditors for the auditing of their clients. Most of the organisations spend least on auditors and more on the marketing. That needs to be opposite, Organisations need to spend more on the qualified auditors in their payroll.

3) Auditors on every industry sector- There should be auditors or auditor from every industry sector, they should be aware of all the technical informations that are needed for the auditing purpose. The auditor must be updated with standard specific information that are also need to audit firms.

ISO (INTERNATIONAL ORGANISATION FOR STANDARDISATION)

From the 1920s to the 1940s, the quality products were ensured by the quality control. At the end of a factory production line, there was usually a team of people carrying out inspections to weed out products that would not meet customer requirements. At the end of the 1940s, the Department of Defence in the USA recognised the benefits of a system that had transformed the Japanese Manufacturing Industry. The standardized system, developed by the Department of Defence, was called Quality Assurance and involved organisations establishing procedures to manage all the functions that affected the quality of the manufactured products.

The British Standards Institution (BSI) published the first edition of its BS 5750 series of Quality Assurance Standards in 1979 (focus-consistency). These were designed to be used by any manufacturer. They enabled organisations to become certified, allowing them to display a mark of registration that was issued by the body that carried out the assessment. In 1987, the International Organisation of Standardisation (ISO) based its ISO 9000 family of standards on BS 5750. The ISO 9000 Standards were adopted by the European Community (Now the European Union). They were also adopted (for example) in the UK and the series of standards is called BS EN ISO 9000. 

Although the Standards were identified as being suitable for organisations

delivering services, as well as for those who are engaged in the manufacturing products, some adaptations were needed. In 1994, they were revised to make them more user-friendly for service industries (Focus-customer satisfaction), and by the year 2000 a major revision was complete (Focus-Continual Improvement).

ISO as in ISO 9001 represents International Organisation for Standardisation. The word derived from the greek word "ISOS" which mean "Equal". ISO (International Organisation for Standardisation) is the World's Largest Developer and publisher of International Standards. ISO is a network of the national standards institutes of more than 160+ countries with one member per country and a Central Secretariat in Geneva, Switzerland to coordinates the system. ISO is a Non-Government organisation that forms a bridge between the public and private sectors.

On the one hand, many of its member institutes are part of the governmental structure of their countries. or are mandatory by their government. On the other hand, other members have their roots uniquely in the private sector, having been set-up by the national partnerships of the industry associations.  Therefore, ISO enables a consensus to be reached on solutions that meet both the requirements of business and the broader needs of society.

Because "International Organization for Standardization" would have different acronyms in different languages ("IOS" in English, "OIN" in French for Organisation internationale de normalisation), its founders decided to give it also a short, all-purpose name. They chose "ISO", derived from the Greek isos, meaning "equal". Whatever the country, whatever the language, the short form of the organization's name is always ISO.
