The step most authors miss
Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.
Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.
What ISO is and how it works
ISO is a worldwide federation of national standards bodies, one per country, headquartered in Geneva. It does not regulate or enforce; instead it convenes experts in technical committees who draft standards by consensus, which member countries then vote to adopt. The published documents codify agreed best practice — for example how to run a quality management system or secure information. Because ISO is independent of any single government, its standards are designed to be neutral, internationally applicable and usable across borders, which is why they underpin much of global trade and procurement.
Why ISO is not an acronym
A common assumption is that ISO stands for the initials of its English name, but the letters do not match (which would be IOS). The founders chose a single short form derived from the Greek word isos, meaning equal, so the organisation would have one consistent name regardless of language or word order. This avoids different abbreviations in French (Organisation internationale de normalisation) or other languages. The choice also signals the body’s purpose: bringing things into a common, equal standard that everyone can rely on.
What ISO standards cover
ISO has published thousands of standards spanning quality management (ISO 9001), environmental management (ISO 14001), information security (ISO/IEC 27001), medical devices (ISO 13485), laboratory competence (ISO/IEC 17025), and management of artificial intelligence (ISO/IEC 42001), among many others. Some are written as certifiable requirements, against which an organisation can be independently audited; others are guidance, vocabularies or test methods. Many information-technology standards are produced jointly with the IEC, which is why they carry the ISO/IEC prefix.

Common misconceptions
What people often get wrong
Often heard: ISO stands for International Standards Organization.
Actually: ISO is not an acronym. The name comes from the Greek isos, meaning equal, chosen so the body has one short form in every language. The full English name is the International Organization for Standardization, whose initials would be IOS, not ISO.
Often heard: ISO is a government agency that enforces its standards.
Actually: ISO is an independent, non-governmental organisation. It develops standards by expert consensus but has no enforcement power. Most ISO standards are voluntary; they become binding only when a regulator, customer or contract chooses to require them.
Often heard: Being ISO-certified means ISO itself issued the certificate.
Actually: ISO does not audit organisations or issue certificates. Independent certification bodies do that against ISO standards. ISO writes the standard; accredited third parties assess conformity and grant certification.
