BS EN 14358:2016给出了根据试验结果确定特征值的统计方法 从明确定义的参考群体中抽取样本，例如实木、紧固件、连接器 以及木质产品。特征值是对参考特性的估计 可基于强度、阻力或密度的5%值以及 刚度的平均值。给出了确定下百分位和上百分位的参数方法。 上五名- 百分位数是95%。本标准适用于型式试验框架内的任何结构产品，以及 工厂生产控制。本文件不包括取样，但参考了相关产品标准。本标准还规定了许多批次的验收程序。根据产品的不同，根据本标准确定的特征值可能不同 直接使用或可能需要相关产品标准中规定的额外调整。 注:例如，对于实木，计算特性的具体调整系数 EN 384中给出了数值。交叉引用:EN 384EN 1990:2002购买时可用的所有现行修订版均包含在本文件的购买中。

BS EN 14358:2016 gives statistical methods for the determination of characteristic values from test results on a sample drawn from a clearly defined reference population of e.g. solid wood, fasteners, connectors and wood-based products. The characteristic value is an estimate of the property of the reference population and can be based on a 5-percentile value of strength, resistance or density as well as on a mean value for stiffness.Parametric methods are given for the determination of lower and upper 5-percentiles. The upper 5- percentile is the 95-percentile.This standard is suitable for use with any structural product in the frame of type testing as well as factory production control.Sampling is not covered by this document, but reference is made to the relevant product standards.This standard also provides the acceptance procedure for verification of a lot.Depending on the product, characteristic values determined in accordance with this standard may be used directly or may need additional adjustments specified in the relevant product standards.Note: For example, in the case of solid timber, specific adjustment factors for calculation of characteristic values are given in EN 384.Cross References:EN 384EN 1990:2002All current amendments available at time of purchase are included with the purchase of this document.
