本文件规定了水泥性能恒定性（AVCP）评估和验证方案，包括性能恒定性认证。该文件规定了工厂生产控制、在制造厂取样的进一步测试（自动控制测试）和水泥性能评估、制造厂和工厂生产控制的初步检查、持续监督的技术规则，工厂生产控制评估和样品审核测试。它还规定了在不合格情况下应采取的行动的规则和对仓库的要求。在本文件中，“水泥”一词既指EN 197 1中定义的普通水泥，也指相关产品规范标准参考本文件并提交认证的其他水泥和粘合剂。这种水泥是在特定工厂生产的，属于相关产品规范标准中定义和规定的特定类型和特定强度等级。技术报告CEN/TR 14245中给出的指南包含了应用本文件的信息。本文件与涵盖水泥和粘合剂的欧洲标准附件ZA相关联，即EN 197 1、EN 14216、EN 14647、EN 413 1和EN 15743。请注意，起草本单独文件的原因是，其中的规定适用于不同欧洲标准所涵盖的不同产品。指导EN 197 2涉及对提交认证的水泥和粘合剂性能稳定性（AVCP）的评估和验证。它特别涉及对产品进行“进一步测试”的情况，正如《建筑产品条例》下认证系统1+的情况一样。EN 197适用的产品有:普通水泥产品、低热水泥和抗硫酸盐水泥，参考EN 197；极低热特种水泥，参考EN 14216；超硫酸盐水泥，参考EN 15743；铝酸钙水泥，参考EN 14647；砌筑水泥，参考EN 413。

This document specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements, including certification of constancy of performance. The document provides technical rules for factory production control, further testing of samples taken at the manufacturing plant (autocontrol testing) and assessment of the performance of the cement, initial inspection of the manufacturing plant and of factory production control, continuing surveillance, assessment and evaluation of factory production control and audit-testing of samples. It also provides rules for actions to be followed in the event of non-conformity and requirements for depots. In this document, the word “cement” is used to refer both to common cements as defined in EN 197 1 and to other cements and binders for which the relevant product specification standard makes reference to this document and which are submitted for certification. Such a cement is produced at a given factory and belongs to a particular type and a particular strength class, as defined and specified in the relevant product specification standard. The guidelines given in the Technical Report CEN/TR 14245 contain information for the application of this document. This document is linked with Annexes ZA of European Standards covering cements and binders, i.e. EN 197 1, EN 14216, EN 14647, EN 413 1 and EN 15743. NOTE The reason for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards. Guidance EN 197 2 deals with the assessment and verification of constancy of performance (AVCP) of cements and binders that are submitted for certification. It deals in particular with cases where “further testing” of the product is undertaken, as is the case for attestation system 1+ under the Construction Products Regulation. The products for which EN 197 2 is applicable are: the common cement products and the low heat cements and the sulfate resisting cements, refer to EN 197 1, the very low heat special cements, refer to EN 14216, the supersulfated cements, refer to EN 15743, the calcium aluminate cements, refer to EN 14647, and the masonry cements, refer to EN 413 1.
