1. Test items
Measurement accuracy test: This is one of the core points. For weight measurement, standard weights are used and placed on the scale from lighter to heavier. The value displayed on the body fat scale is compared with the actual weight of the weights. The error must be controlled within a very small range. For data such as body fat percentage and muscle mass, a professional human composition analyzer is used as a reference. Volunteers with different physical conditions are invited to test and check the deviation between the measurement results of the body fat scale and the analyzer data. The smaller the deviation, the higher the accuracy, which can provide users with a reliable health reference.
Electrode sensitivity test: The body fat scale relies on electrodes to sense the bioelectrical impedance of the human body. During the test, the human foot environment with different humidity and temperature is simulated to observe whether the electrode can quickly and accurately collect signals. If the electrode sensitivity is not good, it may cause missing or wrong measurement data, affecting the user experience.
Data transmission stability test: After pairing the body fat scale with the mobile phone APP, measure in various scenarios such as different distances and with or without obstacles to check whether the data can be transmitted to the APP in a timely and complete manner to avoid problems such as transmission interruption and data loss, and ensure that users can obtain measurement results at any time.
APP function detection: Check whether the APP can receive data normally, clearly display various physical indicators, and whether the health advice it gives is scientific and reasonable. According to different user data, such as special groups such as the elderly and athletes, judge whether the APP has targeted suggestions.
2. Detection method
Laboratory calibration method: In a laboratory environment with constant temperature, constant humidity, and no electromagnetic interference, use high-precision standard equipment, such as the above-mentioned weights and human composition analyzer, and operate according to strict procedures to accurately measure the performance indicators of the body fat scale, providing authoritative basis for quality assessment.
Simulation scenario test method: Create a common family environment, such as continuous use by multiple people, placed on different ground materials, etc., observe the stability and adaptability of the body fat scale in actual use, including electrode sensing, data transmission and other aspects, which are more in line with real usage.
User experience survey method: Invite user groups of different ages, genders, and occupations to try out the body fat scale and APP, collect feedback, and discover problems such as ease of operation and ease of data interpretation from the user's perspective, to assist in improving product testing.
3. Testing standards
National standards set the bottom line for the basic measurement performance and electrical safety of body fat scales to ensure the safety of consumers; industry standards are divided into home and medical fields based on product positioning, and medical body fat scales have higher requirements in terms of accuracy and data stability to meet professional medical needs; international standards promote product integration with the world and enhance the competitiveness of domestic brands.
4. Significance of testing
For manufacturers, strict testing promotes technological innovation, optimizes product quality, establishes a good brand image, and wins the market; for consumers, they can choose accurate and reliable body fat scales to help scientifically manage health and enjoy a convenient life, thereby promoting the vigorous development of the entire smart body fat scale industry.
