Deadline for coming into operation: 1 October 2014 生效日期：2014年10月1日 Principle 原则
This chapter should be read in conjunction with all relevant sections of the GMP guide Quality Control is concerned with sampling, specifications and testing as well as the organisation, documentation and release procedures which ensure that the necessary and relevant tests are carried out, and that materials are not released for use, nor products released for sale or supply, until their quality has been judged satisfactory.Quality Control is
not confined to laboratory operations, but must be involved in all decisions which may concern the quality of the product.The independence of Quality Control from Production is considered fundamental to the satisfactory operation of Quality Control.本章应与GMP指南中所有相关章节一起解读。

质量控制主要关注取样、质量标准和检测，同时也与组织机构、文件记录和放行程序相关，这些程序保证了必要和相关的测试。

只有当产品和物料的质量被判定为可以接受时，物料才可以放行使用，产品才可以放行销售。

质量控制不仅局限于化验室操作，还必须包括所有可能与产品质量相关的其它决定。

质量控制独立于生产被认为是质量控制可以令人满意地操作的基础。

其维护和控制方式应能保证适用于其用途。

应对其进行标识，保留充分的记录显示其使用历史。

On-going stability programme 持续稳定性试验方案 6.26 After marketing, the stability of the medicinal product should be monitored according to a continuous appropriate programme that will permit the detection of any stability issue(e.g.changes in levels of impurities or dissolution profile)associated with the formulation in the marketed package.上市后，药品的稳定性应根据适当的持续方案进行监控，这样可以发现所有与上市包装配方有关的稳定性问题（例如，杂质水平变化、溶出度概况变化）。

6.27 The purpose of the on-going stability programme is to monitor the product over its shelf life and to determine that the product remains, and can be expected to remain, within specifications under the labelled storage conditions.持续稳定性考察的目的是在货架期内对产品进行监控，确认产品在标识的存贮条件下能，或预期能符合质量标准。

6.28 This mainly applies to the medicinal product in the package in which it is sold, but consideration should also be given to the inclusion in the programme of bulk product.For example, when the bulk product is stored for a long period before being packaged and/or shipped from a manufacturing site to a packaging site, the impact on the stability of the packaged product should be evaluated and studied under ambient conditions.In addition, consideration should be given to intermediates that are stored and used over prolonged
periods.Stability studies on reconstituted product are performed during product development and need not be monitored on an on-going basis.However, when relevant, the stability of reconstituted product can also be monitored.这主要适用于市售包装的药品，但也要考虑散装产品。

例如，如果散装产品在包装和/或从生产场所发运至包装场所前存贮了相当长时间，则包装后产品稳定性受到的影响需要进行评估，并在室温条件下进行考察。

另外，还要考虑存贮并在延长的时间内使用的中间体。

再生产品的稳定性研究已经在研发期间做过了，不需要持续考察。

但如果需要，也应该监控再生产品的稳定性。

6.29 The on-going stability programme should be described in a written protocol following the general rules of Chapter 4 and results formalised as a report.The equipment used for the ongoing stability programme(stability chambers among others)should be qualified and maintained following the general rules of Chapter 3 and Annex 15.持续稳定性试验应在一份书面方案中描述，应符合第4章的一般规则，试验结果应汇总作为一份报告。

持续稳定性试验所用设备（稳定性考察箱）应根据第3章和附录15的一般要求进行确认和维护。

6.30 The protocol for an on-going stability programme should extend to the end of the shelf life period and should include, but not be limited to, the following parameters: 持续稳定性计划方案应延长至产品的货架期，方案应包括，但不仅限于以下项目： i.Number of batch(es)per strength and different batch sizes, if applicable;适用时，每个剂量和不同批量的批数
ii.Relevant physical, chemical, microbiological and biological test methods;相关物理、化学、微生物和生物检测方法iii.Acceptance criteria;可接受标准
iv.Reference to test methods;检验方法引用标准
v.Description of the container closure system(s);容器密闭系统
的描述
vi.Testing intervals(time points);检测间隔（时间点）
vii.Description of the conditions of storage(standardised ICH/VICH conditions for long term testing, consistent with the product labelling, should be used);存贮条件的描述（ICH/VICH长期稳定性标准条件，应与产品标签一致）viii.Other applicable parameters specific to the medicinal product.药品特定的其它适用参数
6.31 The protocol for the on-going stability programme can be different from that of the initial longterm stability study as submitted in the marketing authorisation dossier provided that this is justified and documented in the protocol(for example the frequency of testing, or when updating to ICH/VICH recommendations).如果经过证明，并记录在方案中（例如，检测频次，或根据ICH/VICH建议更新），则在检的稳定性方案可以与初始提交申报上市许可的长期稳定性试验方案不同。

6.32 The number of batches and frequency of testing should provide a sufficient amount of data to allow for trend analysis.Unless otherwise justified, at least one batch per year of product manufactured in every strength and every primary packaging type, if relevant, should be included in the stability programme(unless none are produced during that year).For products where on-going stability monitoring would normally require testing using animals and no appropriate alternative, validated techniques are available, the frequency of testing may take account of a risk-benefit approach.The principle of bracketing and matrixing designs may be applied if scientifically justified in the protocol.批数和检测频次应能提供足够量的数据来进行趋势分析。

除非另有说明，在生产品种每个剂量、每个内包形式，如果对稳定性有影响的话，至少每年增加一批至稳定性试验中（除非
该年度未生产该品种）。

对于正常需要用动物进行检测，且并没有适当的可以替代的、经过验证的技术的情况，其测试频次可以采用风险-利益权衡方法决定。

如果在方案中经过科学论证，也可以采用括号法和矩阵法设计原则。

6.33 In certain situations, additional batches should be included in the on-going stability programme.在特定情形下，要增加批次到持续稳定性试验中。

For example, an on-going stability study should be conducted after any significant change or significant deviation to the process or package.Any reworking, reprocessing or recovery operation should also be considered for inclusion.例如，在重大变更或工艺或包装发生重大偏差时，应进行持续稳定性试验。

所有返工、再加工或回收操作也应考虑进行稳定性试验。

6.34 Results of on-going stability studies should be made available to key personnel and, in particular, to the Qualified Person(s).Where on-going stability studies are carried out at a site other than the site of manufacture of the bulk or finished product, there should be a written agreement between the parties concerned.Results of on-going stability studies should be available at the site of manufacture for review by the competent authority.关键人员应可以获得持续稳定性试验的结果，特别是授权人。

如果持续稳定性考察不是在原料药或制剂的生产场所实施，则相关方之间应该有一份书面协议。

在生产场所需要保留有持续稳定性试验的结果，以便官方审核。

6.35 Out of specification or significant atypical trends should be investigated.Any confirmed out of specification result, or significant negative trend, affecting product batches released on the market should be reported to the relevant competent authorities.The possible impact on batches on the market should be considered in accordance with Chapter 8 of the GMP Guide
and in consultation with the relevant competent authorities.OOT 或重大的非典型趋势应进行调查。

所有确认过的OOT结果，或重大不良趋势，如果对对上市放行的批准有影响，则需要报告给相关的药监部门。

对已上市批次可能产生的影响应根据GMP指南第8章处理，并考虑相关药监部门的建议。

6.36 A summary of all the data generated, including any interim conclusions on the programme, should be written and maintained.This summary should be subjected to periodic review.对所有产生的数据，包括对试验结果的暂时结论，均应进行书面汇总并留存。

该汇总应进行定期评审。

Technical transfer of testing methods 检验方法的技术转移
6.37 Prior to transferring a test method, the transferring site should verify that the test method(s)comply with those as described in the Marketing Authorisation or the relevant technical dossier.在检验方法转移之前，转出方应确认方法符合上市许可或相关的技术文件。

6.38 The original validation of the test method(s)should be reviewed to ensure compliance with current ICH/VICH requirements.A gap analysis should be performed and documented to identify any supplementary validation that should be performed, prior to commencing the technical transfer process.要对检验方法的原始验证进行审核，以保证符合现行ICH/VICH要求。

要进行差距分析，并记录以识别在进行技术转移过程前，是否需要进行补充验证。

6.39 The transfer of testing methods from one laboratory(transferring laboratory)to another laboratory(receiving laboratory)should be described in a detailed protocol.应制订一个详细的方案说明如何将检验方法从一个化验室（转出化验室）转移至另一个化验室（接收化验室）。

6.40 The transfer protocol should include, but not be limited
to, the following parameters: 转移方案应包括，但不仅限于，以下参数
i.Identification of the testing to be performed and the relevant test method(s)undergoing transfer;
识别要进行的检测项目和相关的需要转移的检验方法；ii.Identification of the additional training requirements;识别新增的培训要求；
iii.Identification of standards and samples to be tested;识别要测试的标准和样品；
iv.Identification of any special transport and storage conditions of test items;识别检测项目是否有特殊运输和存贮条件；
v.The acceptance criteria which should be based upon the current validation study of the methodology and with respect to ICH/VICH requirements.基于现行的方法学验证研究以及ICH/VICH 要求制订的可接受标准。

6.41 Deviations from the protocol should be investigated prior to closure of the technical transfer process.The technical transfer report should document the comparative outcome of the process and should identify areas requiring further test method revalidation, if applicable.与方案不符的偏差在技术转移过程完成前要进行调查。

技术转移报告应记录转移过程中的对比结果，必要时，应指出需要进一步验证的方面。

6.42 Where appropriate, specific requirements described in others European Guidelines, should be addressed for the transfer of particular testing methods(e.g Near Infrared Spectroscopy).适当时，特殊的检测方法（例如近红外光谱）的转移中应指明其它欧洲指南中的要求。

第二篇：质量控制
质量控制
1清除焊渣、毛刺；质检要求：毛刺打平，焊渣除净。

2除油除锈；
质检要求：预涂件表面无油污、锈蚀和氧化皮；表面平整。

3磷化(含表调)；质检要求：
a.磷化膜细致、均匀；
b.膜厚1～3 μm。

4水洗；质检要求：a.预涂件表面不得返锈(发黄)；b.预涂件洗水滴液：电导率＜50μs/cm；PH＜6.5。

应指出，该工序对洗水水质要求较高，这是保证水洗质量的重要环节，生产及其管理者应做好纯水生产水质的监控工作，把好质量关。

5电沉积；质检要求：电泳漆液均匀、细腻，呈均相状态；漆液固含量、颜基比、电导率、pH值(助剂含量)、浴温及施工电压(电流)均处于正常范围。

6电沉积后洗；质检要求：洗液流量，压力均正常；手触湿膜：干净；指压湿膜：压印明显—涂膜厚度可望获得保证。

7干燥固化。

质检要求：a.对刚出烘炉涂件的检测：涂膜不发黄、发脆，如出现上述情况，说明烘烤温度过高；趁热触摸涂件不粘手，如粘手，说明温度偏低，涂膜内在质量将降低；涂膜色泽正常。

b.仪器检测涂膜厚各项指标均符合质量技术要求。

阴极电泳涂装的质量管理2.1阴极电泳涂装的典型工艺流程由于处理的材质和表面状态不尽相同，所以所采用的工艺流程、特别在前处理的工艺上也不完全相同。

但其总体要求是一致的。

较为常见的流程如下：机加工成形产品→清除焊渣毛刺→上线→脱脂(除锈)→水洗→表调磷化→水洗→电沉积→电泳后洗→干燥固化→产品。

2.2涂膜质量问题及质量要求由于受到各种因素的影响，涂膜将出现各种质量问题，归纳起来主要分为两大类：(1)外在质量即装饰质量问题，主要是颜色、光泽和平整度三项，其质量要求主要看该涂膜是作底漆还是作“底、面合一漆”的不同而异。

(2)内在质量问题，包括机械性能和耐腐蚀性能两方面。

·机械性能涂膜附着力(级)：级数越大表示附着力越差，一般以“0”级为最好。

涂膜厚度(μm)：由于受到电阻的影响，涂膜厚度总会受到某种程度的限制。

一般而言，涂膜不宜太薄，太薄不仅降低其光泽和平整度，而且会降低涂膜综合性能。

不管属于何种产品，增加涂膜厚度，对提高涂膜的光泽、丰满度和内在质量都是有利的，但从降低涂装成本考虑，过厚是不必要的。

涂膜硬度(H)：硬度适中为好(如2H)。

过小将降低其机械性
能，同时，其耐腐蚀性能亦无法得到保证；过大，涂膜变脆，其柔韧性、耐冲击性将降低，在很多情况下都会降低涂膜的使用寿命。

涂膜柔韧性(mm)：这是一项保证涂膜使用寿命的重要指标，一般以试验涂膜裂纹长度小于2mm为符合要求。

冲击强度：一般要耐50cm的冲击才符合要求。

·耐腐蚀性能包括耐水性、耐汽油性、耐化学药品(酸、碱)性，常用耐盐雾性综合表示。

对阴极电泳涂膜而言，其耐盐雾性至少要达到720h以上才符合要求。

涂膜的机械性能对涂膜的耐腐蚀性起着非常重要的作用，用户亦应加以重视。

2.3涂膜质量的影响因素在阴极电泳涂装中，影响涂膜质量的因素主要有5个。

(1)购进的涂料产品质量不佳或不稳定。

此因素对涂膜质量的影响是首要的，影响的大小视产品质量优劣程度的不同而异。

(2)预涂件的材质及表面状态。

预涂件材质及表面状态用现有的表面处理方法或工艺无法提供质量保证，即表面处理方法(工艺)不佳、不完善所致。

表面处理方法虽好但操作不到位，导致处理质量不过关。

此因素对涂膜质量的影响较为广泛，不仅影响涂膜的外观质量，而且将影响涂膜的附着力、厚度乃至它的耐腐蚀性能。

因此，它不仅是一个从始至终不能放松警惕的操作因素，而且也是工艺设计者需要着意研究解决的重要课题。

(3)电泳槽液不稳定，涂料溶解性、分散性差，乳化效果不好，导致电泳特性差。

影响电泳槽液稳定及其电泳特性的因素有：涂料产品质量(差)；槽液工艺参数控制不到位；循环搅拌系统失控、运营不正常；杂质离子(污物)干扰和破坏。

这是一个大的影响因素。

此因素对涂膜质量的影响是全面的甚至是致命的。

涂膜质量控制的重点和难点基本集中于此。

(4)电沉积后水洗不充分，多余涂料未洗净或洗涤冲力过大，将已沉积的湿膜冲薄。

此因素主要影响涂膜的外观质量，或使涂膜变薄。

(5)湿膜干燥固化条件不充分或失控，如：
烘烤温度过高或过低；烘烤时间过长或过短。

此因素对涂膜质量的影响是全面的，不仅影响它的外观质量，而且还影响它的内在质量。

(6)人为因素。

人员技术素质和职业操守好坏不等。

显然，这是一个需要调动和值得开发的因素，涂装线的成功或失败全赖于此。

由上可见，。
