EN ISO 21420 Protective gloves general requirements fit and comfort testing
The European Standard EN ISO 21420 outlines the general requirements for protective gloves used in various industries, focusing on human factors and comfort. This standard is crucial for manufacturers of protective gloves to ensure that their products meet ergonomic and safety standards, thereby enhancing both user comfort and performance.
Human factors testing under this standard focuses on assessing how well a glove fits an individual wearer and provides comfort during prolonged use. This includes evaluating the glove's dimensions, fit, and adjustability, as well as its ability to maintain a comfortable fit throughout the working day. The aim is not only to ensure that gloves do not restrict movement but also that they are designed with ergonomics in mind.
The standard defines several key parameters for measuring fit and comfort:
- Length and circumference of the glove
- Finger length, width, and curvature
- Thumb position and fit
- Cuff design and fit
The testing process involves multiple stages. Initially, a sample population is selected to represent typical users. This group may include different hand sizes, shapes, and genders, ensuring that the findings are broadly applicable.
Once the sample population is established, each individual's hands are measured using precise instruments such as calipers for dimensions like length and circumference. The gloves are then fitted onto these measurements to determine how well they match with the user’s hand anatomy.
The comfort aspect of the test involves evaluating factors such as:
- Pressure points
- Restriction of movement
- Heat retention and dissipation
- Sweat management
A standardized set of tasks is performed by the test subjects to simulate real-world scenarios. This helps in assessing whether the gloves impair dexterity or hinder performance during typical job functions.
The results from these tests are analyzed using statistical methods, comparing the measured dimensions and user feedback against predefined criteria outlined in EN ISO 21420. Compliance with this standard ensures that protective gloves not only protect users but also enhance their working experience by providing a comfortable fit.
At Eurolab, we utilize state-of-the-art facilities and experienced personnel to conduct these tests rigorously, adhering strictly to the methodologies prescribed in EN ISO 21420. Our comprehensive approach ensures that our clients receive accurate, reliable data on their product's compliance with this important standard.
Scope and Methodology
| Aspect | Description |
|---|---|
| Sample Selection | A diverse group of individuals representing typical users, including variations in hand size, shape, and gender. |
| Glove Fitting | The process involves measuring the hand dimensions using calipers and fitting gloves to these measurements. |
| Comfort Evaluation | Evaluation of pressure points, movement restriction, heat retention/dissipation, and sweat management through standardized tasks. |
The methodology for EN ISO 21420 testing is designed to ensure that protective gloves meet ergonomic standards, enhancing user comfort without compromising safety. The use of precise measurement tools and standard operating procedures guarantees accurate results that are both reliable and repeatable.
