4.2.3 Fluid Resistance
The test method shall be as specified in TE method 109-121012. Three markers as prepared as in
Clause 5.1 shall be completely immersed in each of the fluids for the times and at the temperatures
specified in the requirements table. The volume of the fluid shall not be less than 20 times that of the
specimen. After immersion, the markers are lightly blotted with tissue paper to remove excess
surface fluid and air dried at 23 ± 2°C (73 ± 7°F) for 45 ± 15min. Samples are tested with a
Crockmeter fitted with ‘Super Twill’ cloth and a 1kg load.
After the print permanence test, marking shall be examined for legibility using normal reading vision.
Print contrast shall be evaluated in accordance with TE Document 411-121002.
4.3 Physical Testing
4.3.1 Dimensions and Longitudinal Change
The test method shall be as specified in TE method 109-121003.
Three marker sleeves shall be tested. The inside diameter of each shall be measured. For
Longitudinal changed, two gauge marks shall be positioned 100mm apart on each sleeve. The
markers shall be recovered in a fan assisted air-circulating oven and the distance between gauge
lengths and inside diameter of each shall be measured after cooling to room temperature. The
longitudinal change shall be expressed as a percentage of the original gauge length. The minimum
and maximum recovered wall thickness shall be determined.
4.3.2 Tensile Strength and Ultimate Elongation
The test method shall be as specified in TE method 109-121002. Test five recovered tubular specimens
125mm long. An initial jaw separation of 50mm with a gauge length of 20mm and rate of jaw
separation of 50 ± 5mm per minute shall be used.
4.3.3 Specific Gravity
Samples of un-printed product shall be tested to the procedure as specified in TE method 109-
121015. Three specimens of fully recovered tubing 25mm long should be tested. Test specimens
should be prepared to prevent trapping of air.
4.3.4 Split Testing
The test method shall be as specified in TE method 109-121031. Ten perforated or scored marker
sleeves should be tested. Samples should be recovered, onto an ambient temperature mandrel for five
minutes in the fan assisted oven at 150°C (302°F). Samples should be examined for splitting after they
have been cooled down to room temperature.
