Some standard content:
GB8368--1998
This standard is equivalent to IS08536-4:1998 "Medical Infusion Equipment Part 4: Disposable Infusion Set Gravity Infusion Type". It is also a revised version of GB8368--93. The main technical differences between this standard and IS08536-4:1998 are as follows: This standard adds technical indicators such as the filtration rate of the air filter, the wall thickness and outer diameter of the hose, the adjustment stroke of the flow regulator, and the residual amount of ethylene oxide; the international standard for the test of pH in the chemical requirements adopts the titration method, while this standard adopts the acidometer method; the determination method of the particulate content and the hose length index of this standard are different from the international standard, and the inspection rules of sub-appendix H are added. The main technical differences between this standard and GB8368.---93 are as follows: In terms of physical requirements, the requirements for particulate contamination, sealing, bottle stopper piercer, air filter, hose size, drip bucket, flow regulator, injection piece, protective cover, external cone joint, etc. have been changed; in terms of chemical requirements, the test method has been changed from reference to equivalent international standards, so the technical indicators have changed greatly accordingly, the test items have cancelled chloride, and added cadmium content determination and ultraviolet absorbance, etc. Some changes have also been made in the packaging mark. This revision of this standard incorporates the relevant contents of YY0002-90 "Disposable Liquid Filter for Infusion Sets" and YY/T0142-94 "Disposable Air Filter for Infusion and Blood Transfusion Sets" into this standard. This standard replaces GB8368--93 from the date of implementation. YY0002-90 and YYT0142-94 will be abolished at the same time. Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F, Appendix G and Appendix H of this standard are all appendices of the standard. The appendix of this standard is a suggestive appendix.
This standard is proposed by the State Drug Administration. This standard is under the jurisdiction of the National Technical Committee for Standardization of Medical Infusion Equipment. The drafting unit of this standard is the Quality Inspection Center for Medical Polymer Products of the State Drug Administration. The main drafters of this standard are Wu Ping, Wang Yanwei, Qin Dongli, Zhang Qiang and Luo Hongyu. This standard was first issued in 1987.

ISO Foreword
ISO (International Organization for Standardization) is a worldwide federation composed of national standardization bodies (ISO member bodies). The work of formulating international standards is usually completed by the technical committees of ISO. If each member body is interested in the standard project established by a technical committee, it has the right to participate in the work of the committee. International organizations (official or unofficial) that maintain contact with ISO may also participate in the relevant work. In the field of electrotechnical standardization, IS(I) maintains a close cooperative relationship with the International Electrotechnical Commission (IEC). The draft international standards formally adopted by the technical committee are submitted to the member groups for voting. The international standards must be approved by at least 75% of the member groups participating in the voting.
