'''Conformance testing'''
Testing is often either [[event condition action|logical test]]ing or [[physical test]]ing. The test procedures may involve other criteria from [[test functions for optimization|mathematical testing]] or [[chemical test]]ing. Beyond simple conformance, other requirements for efficiency, interoperability, or compliance may apply.
Aside from the various types of testing, related conformance testing activities include:▼
Conformance testing may be undertaken by the producer of the product or service being assessed, by a user, or by an [[accredited]] independent organization, which can sometimes be the author of the standard being used. When testing is accompanied by [[certification]], the products or services may then be [[Advertising|advertised]] as being certified in compliance with the referred [[technical standard]]. Manufacturers and suppliers of products and services rely on such certification including listing on the certification body's website, to assure quality to the end user and that competing suppliers are on the same level.

==Forms of conformance testing==
Line 30 ⟶ 29:
=== Software engineering ===
In [[software testing]], conformance testing verifies that a product performs according to its specified standards. [[Compiler]]s, for instance, are extensively tested to determine whether they meet the recognized standard for that language.<ref name="GoerigkTowards99">{{cite book |chapter-url=https://books.google.com/books?id=gM6AS9_XwtgC&pg=PA62 |chapter=Towards Rigorous Compiler Implementation Verification |title=Collaboration Between Human and Artificial Societies: Coordination and Agent-Based Distributed Computing |author1=Goerigk, W. |author2=Simon, F. |editor=Padget, J.A. |publisher=Springer Science & Business Media |pages=62–73 |year=1999 |isbn=9783540669302}}</ref><ref name="CuginiACent01">{{cite book |chapter-url=https://books.google.com/books?id=hrizEY2BWOoC&pg=PA258 |chapter=FORTRAN Test Programs |title=A Century of Excellence in Measurements, Standards, and Technology |author=Cugini, J. |editor=Lide, D.R. |publisher=CRC Press |pages=258–259 |year=2001 |isbn=9780849312472}}</ref>
=== Electronic and electrical engineering ===
In [[electronic engineering]] and [[electrical engineering]], some countries and business environments (such as telecommunication companies) require that an electronic product meet certain requirements before they can be sold.<ref name="WerstiukRelay07" /><ref name="RyanHigh01">{{cite book |title=High Voltage Engineering and Testing |editor=Ryan, H.M. |publisher=The Institution of Electrical Engineers |edition=2nd |year=2001 |pages=726 |isbn=9780852967751}}</ref> Standards for telecommunication products written by standards organizations such as [[American National Standards Institute|ANSI]], the [[Federal Communications Commission|FCC]], and [[International Electrotechnical Commission|IEC]] have certain criteria that a product must meet before compliance is recognized. In countries such as Japan, China, Korea, and some parts of Europe, products cannot be sold unless they are known to meet those requirements specified in the standards.<ref name="COCIRHowDoes">{{cite web |url=https://www.bomcheck.net/rohs/how-does-bomcheck-manage-compliance-with-rohs-restrictions-in-china-korea-japan |title=How does BOMcheck manage compliance with RoHS restrictions in China, Korea and Japan? |work=BOMcheck.net |publisher=COCIR |access-date=22 February 2018}}</ref><ref name="EURLex31993">{{cite web |url=http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=CELEX:31993L0068:en:HTML |title=EUR-Lex - 31993L0068 - EN |work=EUR-Lex |publisher=European Union |date=30 August 1993 |access-date=22 February 2018}}</ref> Usually, manufacturers set their own requirements to ensure product quality, sometimes with levels much higher than what the governing bodies require. Compliance is realized after a product passes a series of tests without occurring some specified mode of failure.

Several international standards relating to conformance testing are published by the [[International Organization for Standardization]] (ISO) and covered in the divisions of ICS 03.120.20 for management<ref name=pccc>{{cite web |last = International Organization for Standardization |author-link = International Organization for Standardization |title = 03.120.20: Product and company certification.

Many countries sign [[mutual recognition agreement]]s (MRAs) with other countries in order to promote trade of and facilitate market access to goods and services, while making it easier to meet a country's conformance testing requirements.<ref name="EC-MRA18">{{cite web |url=https://ec.europa.eu/growth/single-market/goods/international-aspects/mutual-recognition-agreements_en |title=Mutual Recognition Agreements |publisher=European Commission |date=22 February 2018 |access-date=22 February 2018}}</ref><ref name="NISTMutual17">{{cite web |url=https://www.nist.gov/standardsgov/what-we-do/conformity-assessment/mutual-recognition-agreements-mras |title=Mutual Recognition Agreements for Conformity Assessment of Telecommunications Equipment |publisher=National Institute of Standards and Technology |date=6 September 2017 |access-date=22 February 2018}}</ref><ref name="ISO68:2002">{{cite web |url=https://www.iso.org/standard/29363.html |title=ISO/IEC Guide 68:2002 Arrangements for the recognition and acceptance of conformity assessment results |publisher=International Organization for Standards |date=January 2002 |access-date=22 February 2018}}</ref> Additionally, these agreements have the advantage of increasing confidence in conformance assessment bodies (e.g., testing labs and certification bodies),<ref name="NISTMutual17" /> and by extension, product quality.<ref name="ISOWhatIs"/><ref name="WTOTech">{{cite web| url=https://www.wto.org/english/tratop_e/tbt_e/tbt_info_e.htm |title=Technical Information on Technical barriers to trade |work=Trade Topics |publisher=World Trade Organization |access-date=22 February 2018}}</ref> An example is the [[IAF MLA]] which is an agreement for the mutual recognition of accredited certification between IAF Accreditation Body (AB) Member signatories.
