Overview
SIST EN IEC 61254:2026 – Electric shavers for household use – Evaluation of experience and user satisfaction – is an international standard that specifies subjective methods for assessing user experience and satisfaction with men's electric shavers and their trimmers for domestic use. Developed by the Slovenian Institute for Standardization (SIST) and harmonized with European and international regulations (IEC 61254:2026), this standard applies to electric shavers and trimmers with a rated voltage not greater than 250 V.
This second edition constitutes a comprehensive technical revision, replacing the previous 1993 edition. It refines the scope and introduces modern concepts of user experience and satisfaction, aligning with best practices for evaluating consumer perceptions in household grooming products.
Key Topics
- Scope and applicability: Focused on men's electric shavers and integrated trimmers for household use.
- Evaluation focus: Detailed methods for subjective evaluation of user experience and satisfaction.
- User experience: Defined as the perceptions and responses resulting from using an electric shaver.
- User satisfaction: Assessed as the degree to which the product meets user needs and expectations.
- Test panels: Guidelines for selecting and composing representative panels of adult male users.
- Evaluation attributes: Cleanness, shaving time, skin irritation, noise, vibration, handling, and more.
- Statistical methods: Use of ten-point scales and analysis of variance to evaluate and compare results.
- Revised questionnaires: Updated tools in Annex A for structured data collection from test participants.
- Technical changes: Removal of objective measurement methods; all assessments are user-focused and subjective.
- Stages of satisfaction: Separate evaluation of satisfaction regarding product performance/features and overall satisfaction, covering pre-purchase, purchase, and post-purchase stages.
Applications
For Manufacturers and Brands
- Product development: Use the detailed feedback mechanisms to refine designs, features, and instructions based on direct consumer response.
- Benchmarking: Compare different shaver models to identify improvements and enhance future products.
- Marketing claims: Support user-centered marketing with standardized, statistically validated satisfaction scores.
For Testing Laboratories
- Protocol standardization: Apply the methods outlined for consistent evaluation and reporting on user experience across various shaver models.
- Panel management: Follow best practices for test panel composition to ensure representative results.
For Consumer Organizations
- Comparative reviews: Utilize the standard's subjective testing methods to publish comparative ratings and inform public choices.
- Consumer safety: While the standard does not address safety directly, its focus on satisfaction complements product evaluation frameworks.
For Regulatory and Standards Bodies
- Harmonization: Support consistency in appliance evaluation and alignment with international consumer product assessment practices.
