ISO 11540 Air Flow Test For Writing Instruments

Introductions

This machine is based on the "GB21027-2020 General Requirements for the Safety of Student Products" standard (i.e., under the pressure of 1.33KPa, the air ventilation of the pen cap must reach 8L/min), which is a special testing instrument customised for pen cap air permeability testing.

(i.e. under 1.33KPa pressure, the air ventilation of the pen cap must reach 8L/min), and it is a special testing instrument customised for pen cap ventilation testing. It is a special testing instrument customised for pen cap aeration testing. It is mainly used to insert the pen cap completely into

The main purpose is to insert the pen cap completely into an elastic tube with a suitable diameter, air circulation and pressure difference at both ends, in order to measure the air flow of the pen cap.
