Re Foreword Correct the title of Part 1 to read as follows: Part 1: Evaluation and testing within a risk management process Re Subclause 5.3 “Procedure for product release using residue dissipation curves” Second paragraph, second sentence should read: Dissipation of EO from most materials and
8、devices follows first-order kinetics, i.e. (lnEO) (time after sterilization). Re Equation (A.5) Equation (A.5) should read as follows: () ()2222y xyySxynnn=(A.5) Re Equation (A.6) Equation (A.6) should read as follows: yn= (A.6) 2 DIN EN ISO 10993-7 Cor. 1:2011-06 3 Re F.2.2 “Intraocular lens limits
9、 First paragraph, third sentence should read as follows: This is necessary to prevent documented irritation responses of EO to ocular tissue (see References 44, 117, 118, 119 and 167). Second paragraph, third sentence should read as follows: In such cases, References 44, 117, 118 and 119 indicate t
10、hat the level of ECH that results in ocular toxicity is about four times greater than the corresponding EO level. Re Subclause F.2.5 “Devices used in cardiopulmonary bypass procedures” First paragraph, delete the following sentences: At this UTF, the allowable limit would increase to 21 mg EO. The EO limit reflects manufacturers current ability to remove EO from these rather large devices. Re Subclause J.1.1 Footnote 9) should read as follows: 1 mmHg = 133,322 Pa or 760 mmHg = 101,325 kPa.
