检验是质量控制的重要手段之一,从原材料进场到施工过程控制直至结构竣工验收,都离不开检验。抽验是最常见的检验方式,抽验离不开抽检方案。抽验方案与受检项目的重要性、变异性、实际质量水平状况以及生产方和用户方的风险密切相关,为此,设计规范、验收规范和产品标准一般都有专门的章节或附录对抽验方案进行具体的规定。本文介绍了抽验方案的原理并指出了实际工作中的常见问题,对正确理解和应用抽验方案有指导意义。
Inspection is one of the important means of quality control. From raw materials entering into the construction process to the control of the construction process until the completion of construction acceptance, inspections are inseparable. Sampling is the most common method of inspection. Sampling is inseparable from the sampling program. Sampling test program is closely related to the importance, variability, actual quality level status of the project under inspection, as well as the risk of the manufacturer and the user. For this reason, design specifications, acceptance criteria and product standards generally have special chapters or appendices. Make specific regulations. This paper introduces the principle of sampling scheme and points out common problems in practical work, and it has guiding significance for correct understanding and application of sampling scheme.
