Cap Of Pen Air Circulation Tester Application

Pen cap air flow tester is used to stationery manufacturers pen cap ventilation qualified rate inspection, quality supervision departments of stationery manufacturers to produce pen cap inspection, third-party inspection agencies, etc.

Standards

① BS7272-1/-2: 2008 Safety standard for choking prevention of pen caps and pens plugs

② JTS S 6060:1996 Safety requirements for writing pens and marker pens caps for children up to and including 14 years of age

③ ISO 11540:1993 Safety requirements for writing pens and marker caps for children up to and including 14 years of age

④ GB 21027:2007 General requirements for the safety of student products

⑤ GB/T 24110-2009 Safety requirements and test methods for pen caps and end caps for import and export pen products

Principle

This machine is based on the "GB21027-2020 general requirements for the safety of student products" standard (that is, under a pressure of 1.33KPa, the air ventilation capacity of the pen cap must reach 8L/min) production, is a special testing instrument customized for pen cap ventilation testing. Mainly the pen cap is completely inserted into a suitable diameter, air flow, pressure difference between the two ends of the elastic tube, in order to measure the air flow of the pen cap.
