6.1.4. Elasticity of Canula: The elasticity shall be such that with the distal end of the canula in a fixed position, the canula (with the contact point located as in Table 3, Tests, Column 6) after bending a fixed number of degrees to one side as in Table 3, Tests, Column 5 and after being released, shall show no permanent set, i.e., shall return fully to its original shape with no evidence of distortion.

6.1.5. Resistance of Canula to Breakage: The resistance to breakage shall be such that with the distal end of the canula in a fixed position, the canula (with the contact point located as in Table 3, Tests, Column 6), shall not break when bent 20 times at the number of degrees from vertical indicated in Table 3, Tests, Column 2.

6.1.6. Sterility: The sterility test shall be performed under Sterility Tests in the current edition of United State Pharmacopoeia.

6.1.7. Freedom from Pyrogen: Place ten (10) needles in a sterile, pyrogen-free flask, pour 250 mls of sterile, pyrogen-free saline test solution (U.S.P.) into the flask and heat at not less than 85 °C for one (1) hour. The resulting saline extract shall be submitted to the "Pyrogen Test" as described in the current edition of United States Pharmacopoeia.

6.1.8. Safety Tests: Needles with Plastic Hubs: Cover 20 needles with 30 mls of sterile, pyrogen-free saline test solution (U.S.P.) and heat at not less than 85 °C for one (1) hour. Decant the saline solution, inject 1.0 ml. of the eluate intravenously into each of 10 non-fasted, healthy, 28 to 32 gram mice. Observe the animals at 4, 24, and 72 hours after injection for any deaths or discernible symptoms of acute toxicity. Needles with Metal Hubs: Cover 10 needles with 50 ml. of the saline test solution and boil for four (4) hours, then proceed as outline in the previous test,

6.1.9. Resistance to Autoclaving: The needle assembly and protector shall be subject to autoclave sterilization for 20 minutes at 250 °F, under steam pressure. At the end of such time, there shall be no indications of deterioration or distortion of the canula protector or hub, or loosening of the canula within the hub.

6.1.10. Cleanliness of Inside Diameter: Visual examination of the hub with a hand lens shall not reveal any foreign matter, chips or burrs. The hub shall be cleaned with a dry cotton swab and shall be examined with a hand lens (seven (7) magnification) for burrs or foreign matter.

6.1.11. Silicone Test: Canula is pushed through a thin rubber diaphragm and evidence of the coating shall be apparent by the reduction in drag with compared with an uncoated needle.
