ISO 29581-1:2009规定了湿化学法分析水泥的方法。 ISO 29581-1:2009给出了参考方法，在某些情况下，还提供了可被视为等效的替代方法。在发生争议的情况下，仅使用参考方法。 允许使用其他方法，前提是根据参考方法或国际公认的参考材料进行校准，以证明其等效性。如有争议，仅使用参考方法。 ISO 29581-1:2009描述了主要适用于水泥的方法，但也适用于其组成材料。 它们也可以应用于其他材料，这些标准要求使用这些方法。 标准规范说明了使用的方法。

ISO 29581-1:2009 specifies the methods for the analysis of cement by wet chemistry. ISO 29581-1:2009 gives the reference methods and, in certain cases, an alternative method that can be considered to be equivalent. In the case of a dispute, only the reference methods are used. It is permitted to use other methods provided they are calibrated, either against the reference methods or against internationally accepted reference materials, in order to demonstrate their equivalence. In case of dispute, only the reference methods are used. ISO 29581-1:2009 describes methods that apply principally to cements, but which can also be applied to their constituent materials. They can also be applied to other materials, the standards for which call up these methods. Standard specifications state which methods are used.
