Product Description
To test the safety of the caps for writing and marking instruments which are designed or clearly intended for use by children up to 14 years of age.
Caps for writing and marking instruments which are not designed or intended for use by children, e.g. jewellery pens, expensive fountain pens, professional technical pens, are not be test by this method.
Standard
ISO 11540, BS 7272-1, GB/T 24110 |
Test Procedure
1.Cut the elastomeric tubing into length such that when the cap is inserted there is a relaxed diameter of tubing at both ends of the cap when connected to the apparatus.
2.Apply a soap solution or other suitable low viscosity lubricant to the full internal area of the tubing
3.Insert the cap into approximately the center of the tube length and ensure that as far as practicable the cap is parallel to the major axis of the tubing
4.Using suitable connectors and tubing, connect the tube/cap assembly to the apparatus.
5.Turn on the air supply and adjust the flow until the pressure gauge indicated pressure difference of 1.33 kpa
6.Record the flow rate indicated on the flow gauge at this pressure.
7.Turn off the air supply, remove and reverse the tube/cap assembly and repeat above No. 4 and No. 6 steps.
8.Test 10 caps, giving a total of 20 air flow results. Record separately the air flows for each cap tested and report the minimum air flow recorded.
