With the growing popularity of smart measuring tools worldwide, laser tape measures (also known as laser distance meters) have become a sought‑after product in construction, interior design, and DIY sectors, thanks to their high efficiency and accuracy. However, to export these devices to the EU market, manufacturers must clear a critical hurdle – laser safety compliance testing. The testing requirements of the core standards EN 60825‑1 and EN 50689 are a legal prerequisite for affixing the CE mark and gaining access to the 27 EU countries.
Why Do Laser Tape Measures Need Dual‑Standard Testing?
Laser tape measures differ from ordinary electronic products. If the laser beam they emit is not adequately classified for safety, it may pose a potential risk to users’ eyes – especially for consumers who are not professionally trained. In the EU, compliance for laser tape measures follows a two‑tier structure of “basic safety plus specific requirements”:
EN 60825‑1 (the basic standard): This is the general safety standard for laser products. It specifies the safety classification of laser radiation (Class 1 to Class 4), engineering protection requirements, and warning label specifications. All products containing a laser function must comply with this standard.
EN 50689:2021 (the specific standard): This is a supplementary standard developed specifically for consumer laser products. Since ordinary consumers lack professional protective awareness, EN 50689 imposes stricter radiation limits and foreseeable misuse scenario tests on consumer‑oriented laser tape measures compared to industrial‑grade devices.
In short, industrial‑grade laser distance meters only need to pass EN 60825‑1, while consumer‑grade laser tape measures sold in the home improvement and e‑commerce markets must meet the additional requirements of EN 50689.
Understanding the Testing Class and Process
In compliance testing, determining the safety class of the laser tape measure is the core step. According to EU requirements, laser tape measures emitting invisible laser radiation must be Class 1; for visible‑beam devices (typically wavelengths of 630‑670 nm), the safety class is generally limited to Class 2 or Class 3R.
The complete testing and certification process typically includes: consultation with the manufacturer, submission of technical specifications and test samples, laboratory testing of parameters such as radiant power, wavelength, and beam divergence angle according to the standards, issuance of EN 60825‑1 and EN 50689 test reports, and finally integration of technical documentation for CE certification and signing of the Declaration of Conformity.
