I. What is IEC 60335‑2‑27 Testing for Beauty Device Face Masks?
IEC 60335‑2‑27 is an international standard published by the International Electrotechnical Commission (IEC), titled "Household and similar electrical appliances – Safety – Part 2‑27: Particular requirements for appliances for skin exposure to ultraviolet and infrared radiation". This standard is a companion specific standard to the general safety standard IEC 60335‑1, and is specifically designed for household and similar electrical appliances that are equipped with optical radiation emitters and used for skin beauty care.
For beauty device face masks, this standard primarily evaluates the following safety performance aspects:
Optical radiation safety: Measures irradiance of ultraviolet (250‑400 nm) and infrared radiation, assessing potential hazards to skin and eyes.
Electrical safety: Includes protection against electric shock, leakage current, electrical strength, and earthing measures.
Mechanical safety: Structural stability, mechanical strength, resistance to heat and fire, etc.
Marking and instructions: Compliance of product markings, warnings, and user manuals.
The standard applies to single‑phase appliances with a rated voltage not exceeding 250 V, and other appliances not exceeding 480 V, covering both household and commercial scenarios such as beauty salons. It should be noted that this standard does not apply to beauty equipment containing lasers or intense light sources (which correspond to IEC 60335‑2‑113) nor to medical devices (which correspond to the IEC 60601 series).
II. Main Applications of the Test Report
An IEC 60335‑2‑27 test report provides multiple practical benefits for beauty device face mask manufacturers:
E‑commerce platform access: Major e‑commerce platforms such as Tmall,, and Amazon require third‑party test reports for beauty devices as a prerequisite for listing. The safety compliance information in the report directly determines whether the product passes the review.
Export trade compliance: EU CE certification and international CB certification both recognise IEC 60335‑2‑27 as the basic safety basis for beauty phototherapy devices. Holding this report effectively eliminates trade barriers and helps products enter overseas markets.
Bidding and engineering applications: Some government procurement and beauty salon equipment bulk purchase projects require bidders to provide product safety test certificates.
Consumer trust endorsement: An official test report issued by a third‑party organisation serves as objective evidence of product safety, enhancing end‑user confidence in the brand.
III. Test Report Application Process
Obtaining an IEC 60335‑2‑27 test report generally follows these steps:
Step 1: Requirements communication and plan confirmation. Clarify with the testing body the product type, target market (export country), and the applicable standard version (e.g., IEC 60335‑2‑27:2019). The testing body then develops a test plan and provides a quotation.
Step 2: Sample preparation and submission. The manufacturer must provide a certain number of complete samples (typically including spares), along with technical documentation such as user manuals, circuit diagrams, and key component lists.
Step 3: Laboratory testing. The testing body conducts comprehensive testing in accordance with the standard, including optical radiation measurement, electrical strength testing, heating tests, and abnormal operation tests. Optical radiation measurement requires specialised spectroradiometers under specific geometric conditions.
Step 4: Report issuance and review. After testing is completed, the testing body issues an official test report. The report must bear CMA, CNAS, or other accreditation marks to be legally valid.
IV. Timeline
The standard testing cycle is 3 to 15 working days, influenced by the following factors:
Product complexity: Simple face masks have shorter cycles; products with multiple light sources and multiple modes require more test items.
Standard version: Newer standard versions (e.g., IEC 60335‑2‑27:2019) may involve stricter optical radiation classification and measurement requirements.
Rectification requirements: If the first test fails, corrective actions and re‑testing will extend the cycle.
Expedited services: Some organisations offer expedited processing, with turnaround as fast as 1.5 working days (subject to sample conditions).
It is recommended that manufacturers initiate pre‑testing during the product development phase to avoid delays in market launch due to non‑compliance.
