GB/T33464-2016
Standard Operation Procedure (SOP. The English abbreviations are used below) is a written guidance document that specifies laboratory repetitive activities. The scientific preparation and effective implementation of SOP is an integral part of laboratory quality management. Its role is to minimize differences, ensure that all operations comply with relevant requirements, and that the test results continuously issued by the laboratory are reliable and consistent in accuracy; secondly, to enable laboratory technology and experience to be passed on, and the quality of testing will not be affected by personnel changes. This standard is mainly used to guide chemical analysis laboratories to complete method verification or confirmation. After establishing a feasible internal quality control system on this basis, detailed test procedures and internal quality control system texts are compiled based on the referenced test method standards, combined with technical supplements and changes, and guidance on use is provided. 1 Scope
Guide to the Preparation and Use of Chemical Analysis Standard Operating Procedures GB/T33464—2016
This standard specifies the requirements for the preparation, review, approval, release, management and use of SOPs by chemical analysis laboratories for the test methods used, after completing method verification and confirmation and establishing an internal quality control system. This standard does not contain general or routine requirements for the safety of chemical analysis laboratories. This standard applies to the preparation and use of SOPs in chemical analysis laboratories (the term "laboratory" that appears later in this standard is the abbreviation of chemical analysis laboratories).

4 General requirements for SOP
4.1 The preparation of SOP should be included in the laboratory's quality assurance plan, and qualified personnel should be authorized to prepare it in the format specified in this standard. The laboratory should ensure that the SOP is detailed, specific, concise, and conveys accurate and clear information, with strict logic, and can provide practical and effective guidance for testing activities and internal quality control activities. Note: The content requirements of SOP are shown in Chapter 5, and the format requirements are shown in Chapter 6 and the references given in Appendix A. 4.2 The laboratory determines the best test procedure suitable for the laboratory during the method validation or confirmation stage, and prepares the SOP after completing the method validation or confirmation and having sufficient internal quality control plans. Note: Different laboratories may obtain different results when testing the same sample according to the same method. There are two reasons for this. One is the difference in actual operation, which is manifested in partial changes in the test conditions or partial adjustments to the content of the test procedure; the second is the difference in internal quality control measures of different laboratories. 4.3 If necessary, the laboratory should establish corresponding SOPs for different methods or different test objects of the same method. 4.4The core content of SOP should include detailed test process operation requirements for personnel, instruments, reagents, environmental conditions, sample storage and preparation involved in the test, including supplements to the method text, quality assurance plans, internal quality control measures analysis system verification, etc. The laboratory should ensure that these contents are scientific, applicable and operational. 4.5The writing staff should be familiar with the writing requirements and master all the technical contents of the object. The preparation work should include the preparation of SOP drafts, soliciting opinions, organizing discussions, and reviewing.

violates the requirements of relevant laws and regulations and is an unallowable deviation, then corrections will be implemented, recorded and communicated to relevant personnel and departments: If the deviation causes a deviation and is evaluated as an inappropriate deviation, corrective measures should be recorded and taken, and then clear requirements will be made in the SOP. In this case, the SOP should also be revised and the revised requirements 7.2.3 SOP implementation supervision, the laboratory's technical supervisor or quality assurance department, or both, will regularly supervise the actual operation process of the SOP. The situation of each supervision and inspection should be recorded. This supervision activity should be included in the laboratory's quality management plan Note: Ideally, the implementation of the SOP should be supervised at least once a year; the frequency and number of supervisions for the implementation of the SOP by new and in-training personnel should be more.
7.3 SOP revision, review and improvement
GB/T33464—2016
7.3.1 The published SOP should be reviewed regularly or when the test method standard changes to determine whether it needs to be revised or re-compiled to ensure its suitability.
Note: The recommended review cycle is 1 year.
7.3.2 If the test procedure changes due to different sample matrices, the established SOP should be revised. The revised SOP should be accompanied by a statement of the reasons for the revision, and the revised copy should be kept as an archive. 7.3.3 When the SOP is revised, updated or replaced, it needs to be reviewed and approved again. When the basis for preparation undergoes major substantive changes, a new version needs to be published.
7.3.4 Detailed records of review, revision and improvement should be kept. Note: Considering that analytical methods and procedures are not static, due to changes in requirements or the need to improve performance and efficiency, the laboratory should strengthen the responsibilities of relevant professionals, timely collect new technologies and new developments related to SOPs, propose improvement plans for SOPs, and improve them according to the requirements of laboratory technical operation procedures.
8 SOP use
8.1 SOP users should keep the documents well. SOPs that require confidentiality should be strictly kept confidential in accordance with the relevant requirements of the laboratory and SOPs.
The laboratory should ensure that testers can easily access SOPs, and users should ensure that valid versions are used at all times. 8.3 If the SOP allows different procedural options for different test objects, attention should be paid to the consistency of the options and the test objects when using them. If there are confirmed modifications and changes, they should be implemented in a timely manner. 8.4 When the user encounters a situation that is not clearly specified in the SOP, or there are areas that are not applicable or need to be improved, he should report it to the laboratory supervisor in a timely manner. The laboratory supervisor is responsible for organizing relevant technical personnel to discuss and study in a timely manner and make decisions. 8.5 When the laboratory needs to extend the use of methods, it should stipulate the principles of extended use, and re-compile or revise the existing SOP after completing the necessary demonstration, verification or confirmation.
9SOP file management
9.1 The laboratory should establish files to record and save the distribution of SOPs, the holders and the revision of SOPs. 9.2 The laboratory quality assurance department should keep the valid version of SOP. After the SOP is revised or replaced, the obsolete version should be collected in time. If the obsolete version needs to be archived for reference in future work, it should be sorted and marked for identification. 9.3 The laboratory can manage SOP by using electronic documents. Whether it is paper or electronic documents, the key to management is to ensure that only one valid version is in use at any time. The copies or photocopies used at the testing site should be derived from this unique version. If electronic documents are used, the laboratory shall strictly control modification and printing to prevent unauthorized printing and modification. Note: Electronic signatures are allowed in electronic documents, and the laboratory shall have effective management measures. 9.4
