Summary
A certification mark is the manufacturer's declaration that a product meets legal and technical requirements, independently confirmed where the law demands it. This buyer's field guide covers CE, UL/ETL/CSA, FCC, CCC/CQC, PSE, Giteki, KC, UKCA, EAC and RCM - their legal basis, authorities, scope and how to verify them.
Document version: 1.0 | Fact-checked: August 2026 | Regulatory status verified against EU, OSHA, FCC, CNCA, METI, RRA, UK DBT and certification-body sources.
Why certification marks matter
A certification mark is more than a logo: it is the manufacturer's declaration that a product meets specific legal requirements and technical standards, independently confirmed by a recognized body where the law (or market practice) demands it. For industrial safety components such as Type 4 safety light curtains, marks answer four questions buyers should always ask:
- Can this product legally enter the market? (market access — mandatory marks)
- Is the safety claim independently verified? (type examination, listing, functional-safety reports)
- Will it survive an audit or an insurance claim? (traceability to standards and certificates)
- Does it match my machine's target markets? (one product, several marks)
Golden rule: never trust a mark on a datasheet alone — verify the certificate number in the issuing body's online database (see §7). Marks are routinely counterfeited.

2. European Union — CE marking
| Item | Detail |
|---|---|
| Marks | CE (mandatory); GS (voluntary, Germany) |
| Legal basis | Today: Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, LVD 2014/35/EU, RoHS 2011/65/EU, RED 2014/53/EU (wireless). From 20 January 2027: Machinery Regulation (EU) 2023/1230 applies exclusively (Directive repealed; no transition) |
| Product scope | Machinery, safety components, partly completed machinery, control systems |
| Procedure | Manufacturer self-declares (technical file, Declaration of Conformity, user instructions). Notified Body (NB) involvement is required where the product is not fully covered by harmonized standards — e.g., ESPE/safety light curtains, since EN/IEC 61496 is not harmonized → independent type examination is standard practice |
| Harmonized standards to cite | EN ISO 13849-1:2023 (PL), EN IEC 62061:2021 (SIL), EN ISO 12100:2010 (risk assessment), EN IEC 61496-1/-2/-3 (ESPE), EMC generic standards EN IEC 61000-6-2/-4 |
| Typical bodies | TÜV Rheinland, TÜV SÜD, DEKRA, VDE, SGS, Intertek, Bureau Veritas (searchable in the EU NANDO database) |
| What buyers should check | Certificate number & NB number, standards & editions cited in the DoC, harmonization status (OJEU), declaration signed by manufacturer |
Note on safety components: under the Machinery Regulation, safety components (including ESPE) are in Annex I Part B (higher-risk list) — conformity assessment may require EU type-examination by a notified body depending on the standards route used. This is why reputable light-curtain suppliers hold TÜV/DEKRA type-examination certificates alongside CE.
3. North America — USA & Canada
| Item | Detail |
|---|---|
| Marks | UL Listed / Recognized (UL), ETL (Intertek), CSA / cCSAus, cUL / cETL (Canada); FCC mark/ID for radio |
| Legal basis | OSHA 29 CFR 1910.7 (NRTL program); OSHA electrical safety standards requiring listed/approved equipment; FCC 47 CFR Part 15; Canada: Occupational Health & Safety regulations + SCC-accredited bodies |
| Product scope | Electrical/electronic safety equipment used in workplaces — including active opto-electronic protective devices (light curtains), classified by UL under category NIPF ("Active Opto-Electronic Protective Devices"), per UL/ANSI 61496-1/-2 |
| Mandatory? | NRTL listing is de facto mandatory for workplace electrical safety devices — employers are required to use listed equipment, so unlisted products are hard to sell. FCC authorization is legally mandatory (SDoC for Part 15B digital devices; certification by a TCB for intentional radiators — relevant for wireless/radar products) |
| Relevant standards | UL 61496-1/-2 (ESPE), UL 1998 (safety software), UL 60947-1 / CSA C22.2 No. 60947-1 (low-voltage switchgear), NFPA 79 / UL 508A (industrial control panels), IEC/EN 61496 equivalents |
| Typical bodies (NRTLs) | UL, Intertek (ETL), CSA, TÜV Rheinland, DEKRA, SGS |
| What buyers should check | UL file number on UL Product iQ, NRTL status (OSHA list), FCC ID in the FCC database, cUL vs UL (Canada vs US), "Listed" vs "Recognized" (component) marks |
4. China — CCC and voluntary certification
| Item | Detail |
|---|---|
| Marks | CCC (China Compulsory Certification), CQC voluntary mark, CB Scheme certificate |
| Legal basis | CCC catalogue administered by CNCA (国家认监委); GB/T standards adopt international functional-safety standards |
| Product scope | CCC is catalogue-based — household electrical appliances, wires & cables, IT/AV equipment, low-voltage apparatus, etc. Industrial safety sensors (e.g., light curtains) are generally NOT in the CCC catalogue → no mandatory CCC for DADISICK-type products |
| Voluntary routes | CQC certification (quality/safety, widely respected); CB Scheme (IECEE) — a single test report accepted in 50+ countries; China's national certification body CQC is a leading CB testing & certification body |
| Relevant GB standards | GB/T 16855.1 (≈ ISO 13849-1), GB/T 20438 (≈ IEC 61508), GB/T 5226.1 (≈ IEC 60204-1), GB 23821 (safety distances) |
| What buyers should check | CCC certificate number (where applicable), CQC/CB certificate, whether the supplier's GB claims match international editions |
5. Japan
| Item | Detail |
|---|---|
| Marks | PSE (diamond = specified products, round = non-specified), Giteki 技適 mark (radio), VCCI (voluntary EMC) |
| Legal basis | DENAN Law (Electrical Appliances and Materials Safety Act, METI); Radio Act Art. 38-2 (TELEC/TECA certification); VCCI self-declaration |
| Product scope | PSE applies to catalogue electrical appliances for household/general use — industrial sensors are typically out of scope. Giteki applies to any device with a radio transmitter, including radar-based products and wireless versions of sensors |
| Mandatory? | PSE: only for catalogue products. Giteki: yes for radio-emitting devices — a radar level sensor sold in Japan normally carries the Giteki mark |
| Typical bodies | JET, JQA (PSE testing/certification); TELEC, TECA and other registered certification bodies (radio) |
| What buyers should check | Giteki mark + certification number for radar/wireless products; PSE only if the product falls in the catalogue |
6. Korea
| Item | Detail |
|---|---|
| Marks | KC (safety), KC-EMC, KC radio (KCC) |
| Legal basis | Electrical appliances and household goods safety law (administered by KATS); Radio Waves Act (RRA) for EMC & radio registration |
| Product scope | KC safety is catalogue-based (mandatory for listed appliances). For industrial equipment, the common requirement is KC-EMC — supplier's declaration of conformity (SDoC) or registration. Radio transmitters (radar, wireless) require KC radio certification |
| Mandatory? | KC safety: catalogue only. KC-EMC: required in practice for electrical/electronic equipment sold into Korea. KC radio: mandatory for transmitters |
| Typical bodies | KTL, KETI, KTR (testing/certification); RRA for radio |
| What buyers should check | KC-EMC registration number; KC radio certification for wireless/radar models |
7. United Kingdom (Great Britain & Northern Ireland)
| Item | Detail |
|---|---|
| Marks | UKCA and/or CE; Northern Ireland: CE (or UKNI + CE) |
| Legal basis | Supply of Machinery (Safety) Regulations 2008 (SI 2008/1597), EMC Regulations 2016 (SI 2016/1091), LVD SI 2016/1101, RED SI 2017/1206; new GB Regulations 2026 (Supply of Machinery (Safety) (Amendment and Transitional Provisions) Regulations 2026) in force 14 January 2027 |
| Current position (2026) | The UK recognizes CE marking indefinitely in Great Britain for machinery and most product categories (21 product regulations) — CE-marked products can be placed on the GB market without UKCA. UKCA remains an optional alternative. Northern Ireland continues to follow EU rules (CE mandatory) |
| Alignment | The GB Regulations 2026 align the UK machinery framework with Regulation (EU) 2023/1230 — products must comply with that regulation's requirements to benefit from CE recognition from 14 Jan 2027 |
| Procedure | Conformity assessment mirrors the EU route; UK Approved Bodies (e.g., BSI, TÜV, Intertek, SGS) replace EU Notified Bodies for UKCA |
| What buyers should check | Whether the DoC cites the 2008 Regulations and/or 2023/1230; Approved Body involvement for type examination; NI vs GB route |
8. Other markets worth knowing (compact)
| Market | Mark | Basis | Notes for sensor suppliers |
|---|---|---|---|
| Eurasian Economic Union (Russia, Belarus, Kazakhstan…) | EAC | TR CU 010/2011 (machinery), TR CU 020/2011 (EMC) | Mandatory; certification bodies accredited in EAEU member states |

10. Buyer checklist for safety sensors
When evaluating a safety light curtain / ESPE / safety sensor for a machine:
- Safety rating: Type class (EN/IEC 61496: Type 2/3/4), PL (ISO 13849-1: b–e) and SIL (IEC 62061 / IEC 61508: 1–3) stated explicitly — e.g., "Type 4, PL e (Cat. 4), SIL 3".
- EU: CE DoC naming the directives/regulation and standards cited; NB/type-examination certificate number for ESPE.
- US/CA: NRTL mark (UL/ETL/CSA) with a searchable file number; FCC ID if wireless/radar.
- Other target markets: Giteki (JP), KC-EMC/KC radio (KR), EAC (EAEU), RCM (AU/NZ) as applicable.
- Certificate vs. datasheet: confirm the certificate number and issuing body, and that the product marking matches the certificate.
- Versions: standards editions (e.g., IEC 61496-1:2020, ISO 13849-1:2023, IEC 62061:2021) should be current — old editions indicate legacy designs.
DADISICK Type 4 safety sensors are type-examined and dual-rated PL e / Category 4 / SIL 3, with CE conformity documentation, UL/CSA and further market certifications as applicable — always request the current certificate pack for the exact model you are specifying.
