The international common nitrile glove test standard is EN455, what machine is used to test the quality of nitrile gloves, and what kind of standard is EN455? Today, Fengwang describes these problems for everyone, feel free to contact me about nitrile glove making machines for sale.
What are the Features of En455
The standard is the European standard for disposable medical gloves, which is divided into four parts, respectively:
En455-1 Non-porous test. This standard requires that gloves must be holeless, and the machine required is the glove watertight testing machine.
En455-2 Physical performance test. This test content is the size of the glove, elongation at break, tensile strength and other physical properties.
EN 455-3 Biocompatibility testing. The content of this test is skin irritation, sensitization test and cytotoxicity test to ensure that it does not cause allergy and is harmless to human beings.
EN 455-4 Shelf life and stability tests. Ensure stable performance of gloves during storage and use.
Why Choose Fengwang Glove Watertight Testing Machine
Glove Watertight Testing Machine Test Method
First of all, the glove watertight testing machine is used to do the En455-1 non-porous test.
1. Inflation method: Inflate the glove to 1.5 times the pressure, keep it for some time, and observe whether the air pressure drops to ensure that the glove is free of holes.
2. Water filling method: Pour water into the gloves and observe whether water oozes out. Determine whether the gloves meet the standard according to the proportion of oozing gloves in the total number of tested gloves.
CE Certification
The CE mark indicates that the product complies with the requirements of the European Medical Device Directive. To ensure the objectivity and authority of the test results, it is recommended to test through a third-party testing organization.
Fengwang Glove Watertight Testing Machine Characteristics
1. High-precision detection: Using high-precision pressure sensor and flow sensor, can accurately detect small leakage of gloves.
2. A variety of test methods: this includes the inflation method and the water filling method test.

How is the Fengwang Glove Watertight Testing Machine Made
1. Rack and shell
The frame and housing are usually made of high-strength metal materials with anti-corrosion and dust-proof characteristics to ensure the stability and durability of the equipment.
2. Test the cavity
Sealed chamber: Used to place the tested item, the interior of the chamber is designed as a sealed structure to ensure no leakage during the test.
Fixture: Used to hold the item under test, the fixture is usually adjustable to accommodate products of different shapes and sizes.
Transparent viewing window: Some devices are equipped with a transparent viewing window for real-time observation of the test process.

2. Pressure system
Air/vacuum pumps: Used to generate positive or negative pressure for aeration or vacuum testing.
Pressure sensor: real-time monitoring of pressure changes in the test chamber to ensure test accuracy.
Pressure regulating valve: used to accurately control the test pressure to meet different test requirements.
4. Water circulation system (water filling test)
Water tank: store test water, usually equipped with a water level sensor.
Water pump: inject water into the test chamber or inside the item under test.
Drain valve: discharge water after the test, easy to clean and maintain.
5. Control system
PLC (Programmable Logic Controller): As the core control unit of the equipment, responsible for the execution of test procedures, control of the pressure system and data acquisition.
Touch screen/Control panel: Provides a human-computer interface. Users can set parameters, start tests, and view results on the touch screen.
Sensor module: including pressure sensor, flow sensor, etc., for real-time monitoring of various data in the test process.
6. Data recording and output module
Data storage: Test results are automatically stored in the device’s memory or in an external storage device.
Report generation: Test reports can be generated and can be printed or exported as electronic files (such as PDF, Excel).
Communication interface: Equipped with USB, RS232, or Ethernet interface to facilitate data transmission and device networking.
7. Security protection system
Overvoltage protection: When the pressure exceeds the set value, the device automatically stops and alarms.
Emergency stop button: Stop the operation of the device immediately in an emergency.
Fault self-check: The device automatically detects the status of each module during startup and prompts the user when a fault is found.
Sum up
