Full title and description

ANSI/IEC 60529-2020 — Degrees of protection provided by enclosures (IP Code). This identical national adoption of the IEC IP‑Code specifies the designation, classification and test methods used to state degrees of protection provided by enclosures of electrical equipment against access to hazardous parts, ingress of solid foreign objects (including dust) and ingress of water.

Abstract

Provides definitions, designations (IPxx), requirements and standardized tests for assessing and marking the degree of protection offered by enclosures for electrical equipment (typically for equipment with rated voltage up to 72.5 kV). The document explains the meaning of the first and second characteristic numerals, additional letters, supplementary letters, and prescribes test procedures to verify compliance with each designation.

Scope

This standard applies to the classification of degrees of protection provided by enclosures for electrical equipment (normally for equipment with rated voltage not exceeding 72.5 kV). It covers protection of persons against access to hazardous parts, protection of the enclosed equipment against ingress of solid foreign objects and water, the designation format (IP code), marking and the test procedures required to verify claimed degrees of protection. Product standards may specify complementary or stricter requirements, but the IP designation and tests given here are the reference.

Key topics and requirements

• IP code format and interpretation: first characteristic numeral (solids) and second characteristic numeral (liquids), plus additional and supplementary letters for special protections.
• Definitions and designations for degrees of protection (IP0X through IP6X for solids, IPX0 through IPX9 for liquids and special cases).
• Standardized test methods: solid particle tests (e.g., probe tests, dust‑ingress test) and water ingress tests (dripping, spraying, immersion, high‑pressure jets, powerful water jets and water at high temperatures where applicable).
• Requirements for marking and documentation of IP ratings on equipment and accompanying literature.
• Guidance on applying IP classifications in product standards and on when additional or complementary tests may be required.

Typical use and users

Used by electrical and electronic equipment manufacturers, product designers, test laboratories, certification bodies, standards writers and procurement/specification teams. Typical applications include enclosures for lighting, industrial controls, consumer electronics, outdoor equipment, telecommunications, and any product where environmental ingress (dust, water) and access to hazardous parts must be quantified and communicated.

Related standards

Related documents and adoptions include the original IEC 60529 consolidated editions and amendments (IEC 60529:1989 with Amendments 1 and 2 and subsequent corrigenda), national adoptions and equivalent publications such as EN 60529, CSA C22.2 adaptations and previous NEMA/IEC versions. Product‑specific standards often reference or add requirements to the IP tests in this standard.

FAQ

Q: What is this standard?

A: ANSI/IEC 60529-2020 is the American identical national adoption of the IEC standard that defines the IP (Ingress Protection) Code — a uniform classification system and test procedures for the protection provided by enclosures against access to hazardous parts and ingress of solids and liquids.

Q: What does it cover?

A: It covers definitions, designation format (IPxx), requirements for each degree of protection, and standardized tests (mechanical probe tests, dust tests, various water‑ingress tests) to verify compliance. It also specifies marking and guidance on applying the classification in product standards.

Q: Who typically uses it?

A: Manufacturers, design engineers, test labs, certification bodies, standards committees, and procurement/specification teams who need to classify, test, certify or specify enclosure protection against dust, water and access to hazardous parts.

Q: Is it current or superseded?

A: The ANSI/IEC 60529-2020 edition is listed as the current/active identical national adoption; the standard is based on the IEC IP‑Code text (consolidated editions and corrigenda) and replaces earlier national versions. Users should check the issuing body for any corrigenda or later amendments.

Q: Is it part of a series?

A: Yes — it is the IEC IP‑Code document developed under IEC TC 70 and is commonly referenced alongside related national/adopted versions (EN, CSA, NEMA adaptations) and by product standards that specify enclosure requirements.

Q: What are the key keywords?

A: IP Code, ingress protection, enclosure, dust, water, IP rating, first characteristic numeral, second characteristic numeral, additional letters.
