1、 The essence of CE certification
CE is not a quality trophy, but a manufacturer's declaration of safety compliance for the EU market. Labeling with CE means that you promise that the product meets the basic requirements of relevant EU directives. For industrial lasers, the difficulty lies not in obtaining a certificate, but in the closed-loop evidence chain of laser radiation safety and overall machine safety - reports, risk assessments, instructions, and DoCs must be mutually verified.
2、 How to combine instructions (depending on the product)
The compliance of industrial laser products is usually not a single instruction, but rather a combination of forms:
Laser processing machines (cutting machines, welding machines, marking machines with motion mechanisms): with the Machinery Directive 2006/42/EC as the main axis (gradually switched to the new regulation (EU) 2023/1230 from 2027), laser safety is an embedded requirement.
Pure laser light source/module (without motion mechanism): low voltage command LVD+electromagnetic compatibility EMC+EN 60825-1, generally does not trigger mechanical commands.
Equipped with wireless functions (Wi Fi, Bluetooth, RF remote control): Added the radio device command RED.
Including electronic and electrical components: RoHS 2.0 is a bottom line requirement and almost mandatory.
Medical laser: Following the MDR medical device regulations, the path is independent and not applicable to this framework.
High power industrial equipment (Class 3B/4) is generally a composite compliance system that prioritizes mechanical instructions and ensures laser safety throughout the entire process.
3、 Core Standard Framework
The anchor point for laser radiation safety is EN IEC 60825-1, which is used to determine laser levels, radiation limits, and identification requirements. Processing machines also need to comply with the EN ISO 11553-1 standard for fixed laser processing machines. Use EN ISO 12100 as the risk assessment methodology for the entire machine level; The electrical part complies with EN 60204-1 machine tool electrical safety; The safety chain (interlocking, emergency stop, access control) shall be rated PL level according to EN 13849-1 or EN 62061; EMC adopts EN 55011 and EN 61000-6 series; The reference for optical path closure and observation window protection is EN 60825-4.
In one sentence: 60825 is classified as a level, 11553 as a processing machine structure, 12100 as a risk logic, and the rest as a safety net for electrical and functional safety.
4、 Key points of laser grading and safety design
Classify products into Class 1, 1M, 2, 2M, 3R, 3B, and Class 4 according to EN 60825-1. Industrial cutting and welding are almost all Class 4, which means that any achievable emission may cause damage to the skin or eyes.
The safety design hard indicators for Class 4 devices include:
Beam closure: The shell and observation window have sufficient attenuation of the working wavelength, and the bare fiber joint and collimation port should be included in the reachable emission evaluation.
Interlocking logic: When the protective door or upper cover is opened, the light beam must be cut off, not just the fan; Under a single fault, it still cannot lead to dangerous exposure.
Key switch and emission indicator: Compulsory configuration for Class 3B/4.
Emergency stop and manual reset: The emergency stop light is cut off, and the reset cannot start automatically.
Stray light control: The main beam, reflected light, and scattered light must all have a terminating path.
Identification and instruction manual: complete with grade markings, wavelength, maximum output, goggles rating, and warning language in the local language.
5、 Technical documents and DoC
There must be an auditable document package behind the CE label:
Product specifications and optical parameters (wavelength, power, pulse width, repetition rate, beam parameters)
Structural diagram, circuit diagram BOM
EN 60825-1 Grading Test Report (issued by ISO 17025 laboratory)
EMC report, electrical safety report, RoHS compliance declaration
EN ISO 12100 Risk Assessment Report, covering normal use and foreseeable misuse
Laser safety chapter in user manual and maintenance manual
Design of nameplates and warning labels
Declaration of Conformity by the European Union
Non EU manufacturers are required to designate an EU authorized representative
The retention period for documents is usually at least 10 years after the last product is sold, and can be accessed by customs, buyers, and regulatory agencies at any time.
6、 Authentication Path and Cycle
Low risk modules can self declare; High power complete machines often require the participation of announcement agencies in mechanical safety reviews. Typical rhythm:
Low power module or Class 1-2 light source: sample delivery to report takes approximately 1-2 weeks
Class 4 processing machine: Optical+Electrical+EMC+Mechanical document review takes 3-6 weeks, including rectification, which can take more than 8 weeks
After signing the DoC, affix the CE mark with standardized letter proportions and a height of ≥ 5mm
Note: 60825 report ≠ CE certificate. There is no DoC or overall evaluation, the report is only intermediate evidence.
7、 Common pitfalls
Thinking that 'a laser report is CE' - without DoC and mechanical evaluation, customs clearance is immediately blocked.
Improper touchable point measurement of bare fiber output port, Class 4 leakage is directly judged as unqualified.
Warning language should only be written in English - the official language of the target country must be covered.
Emergency stop only cuts off the drive power without cutting off the beam - the safety chain verification cannot be passed.
According to the old mechanical instruction lock design, the 2027 new regulation switching period is approaching, and new models should reserve compliance interfaces.
8、 One sentence overview
Industrial laser CE=60825 rating+mechanical/electrical/functional safety cover+risk document closed loop+DoC signature labeling. The higher the power, the more complex the mechanism, and the longer the evidence chain; Module level can be lightweight, while whole machine level must be systematized.
