Table 3.
Medication lubricant classification according to IDDSI testing methods at fridge temperature (4 °C). Flow test validity (for fluids at all levels): smooth fluids are valid to be tested using the Flow test, while fluids that contain gristle, bone, husks, shell, fibres or lumps are not valid to be tested. Flow test (for fluids at all levels): the volume of fluid remaining in the syringe after 10 s. Fork Drip test (for fluids at level 3 and 4 in the Flow test): fluid drip and flow manner through fork prongs. Spoon Tilt test (for fluids at level 4 in the Fork Drip test): ability of fluid to hold its shape on the spoon and slide off easily when spoon is tilted.

- Test is not applicable. # Level 3: the amount remained after 10 s is no less than 8 mL, level 4: no flow. * Level < 3: flows continuously through the fork prongs. Level 3: the sample drips in slow dollops through the fork prongs. Level 4: the sample mounds above the fork. ^ Pass: contents easily slide off spoon. Fail: contents are firm and sticky.
