20、tem or any components designed to form a part thereof A.l Principle The drainage system or component(s) thereof, assembled in a ready-buse state, are exposed to the negative pressure stated on the label. The test specimen is inspected while under the negative pressure for evidence of deformation. A.
21、2 Apparatus A.2.1 Water baa, at (37 f 2) “C for the drainage caheter. A.2.2 Water bath, at (23 f 2) “C for other components. A.3 Procedure PerForm the test on the ready-for-use, sterile product. Condition those parts of the drauiage catheter that are intended for insertion into the body in an atmosp
22、here of i % RH or water at a temperature of (37 f 2) “C (A.2.1) for not less than 15 min. Condition other components at 40 % RH to 60 % RH and a temperature of (23 f 2) “C for not less than 15 min and test immediately after conditioning. Submit the non-perforated section of the drainage catheter and
23、or the entire drainage system andor the individuai components thereof (if supplied separately) to the stated negative pressure of the system for 60 s. Mainiain the pressure for at least 60 s. Examine the test specimen by normal or corrected-bnormal vision during the test for evidence of deformation.
24、 Page 5 EN 1617 : 1997 Annex B (normative) Wst method for impact resistance of collection device B.l Principle The collection device is submitted to free fali onto a hard surface and is then examined for evidence of damage in the form of leakage or loss of vacuum. B.2 Apparatus B.2.1 A test sur$e, w
25、hich is: - flat, so that no more than two points on its surface differ in level by more than 2 mm; - rigid, so that it will not be deformed by more than 0,l mm when an area of 100 mm2 is loaded statically with 10 kg anywhere on the surface; - sufficiently large that the device under test falls entir
26、ely upon its surface; - has a mass of at least lobes that of the heaviest device to be tested B.2.2 Means for measung vacuum, capable of showing a difference of 1 % of the maximum vacuum. B.3 Procedure B.3.1 Collection device Assemble the collection device as for clinical use. Fill the collection de
27、vice with water to its collecting capaciw. Perform a free fall at an ambient temperature of (23 2) “C from a height of 700 mm onto a hard surface (33.2.1). Inspect for leakage by normal or corrected-bnomal vision. B.3.2 Suction source Assemble the suction source as for clinical use. Ensure the sucti
28、on source is at the maximum negative pressure and measure and record the pressure. Perform a he fall at an ambient temperature of (23 f 2) “C from a height of 700 mm onto a hard surface (B.2.1).
