DIN EN 14683

Product catalog summary

Overview: The document describes an automated test bench for measuring the pressure difference in medical face masks and community face coverings, compliant with DIN EN 14683 and CWA 17553 standards. The system is designed for ease of use, allowing semi-skilled employees to perform periodic spot checks during production.

Specifications:

The test bench uses the INTEGRA DFM 14683 device, which automates the test process, including setting and monitoring test parameters.
Channel 1 adjusts and measures flow rate; Channel 2 measures pressure difference; Channel 3 (optional) evaluates supplied air flow rate.
256 test parameter sets are available for different product variants, storing processing times, default values, and limit values.
The system includes a mass-flow-controller with a range of 0...16 l/min and a pressure difference measuring range of 0...1400 Pa/cm².
Power supply requirements are 110-230V / 50(60) Hz, approximately 600 W.

Components:

Sample-holder: Designed for breathability and pressure difference testing, with a 25 mm opening width and height adjustment for different material thicknesses.
Vacuum Station: Includes a vacuum pump with a capacity of 12 Nl/min and a final pressure of 50 mbar abs.
Log Printer: Citizen CBM-910II, a dot matrix POS printer for documentation, with a parallel interface.

Operational Features:

Automatic test runs with preset values and limits.
Internal data storage and RS232 printer interface for documentation.
Quick connectors for all connection lines between the sample-holder and test device.

Reference Conditions: Tests are conducted at 23° C and 1000 mbar abs.

Features: With the test station for pressure difference on medical-face-masks, the test is performed according to the specifications of DIN EN 14683 or CWA 17553. The material to be tested (mask, filter material) is manually inserted between the top and bottom part of the sample-holder without wrinkles and closed manually. Using the automatic testing device INTEGRA DFM 14683, the device provides edited settings and monitors all specifications and test parameters automatically. Channel 1 is used for adjustment and counter measurement of the flow rate, according to internal test guidelines. Channel...
