一般用途单芯硬导体无护套电缆产品选购检测管理数据

该检测数据适用于市面上生产销售的一般用途单芯硬导体无护套电缆产品的检测及性能评价。算法通过对测试数据进行不确定度评定，科学反映数据的真实可靠，为产品性能是否合格提供更精确保障，为政府监管、消费者购买提供参考和技术支持。算法根据一般用途单芯硬导体无护套电缆产品性能测量方法和测量程序建立数学模型，确定被测量y（输出量）与其它量（输入量）x1，x2，x3……xN间的函数关系，测量结果Y的不确定度将取决于输入量x1，x2，x3……xN的不确定度及其传播律。从测量仪器、测量环境、测量人员、测量方法等方面，全面梳理确定输入量x 的不确定度来源。评定x 的标准不确定度u（x ），一般应按x1，x2，x3……xN依次逐个评定，然后通过合成分项u（x ），形成最终的不确定度

This detection data is applicable to the detection and performance evaluation of solid conductor unjacketed cables for general purpose manufactured and sold on the market. The algorithm scientifically reflects the authenticity and reliability of test data through uncertainty evaluation of the test data, providing more accurate guarantee for verifying whether the product performance meets the qualified standards, and offering reference and technical support for government supervision and consumer purchasing decisions.

The algorithm establishes a mathematical model based on the performance measurement methods and procedures for solid conductor unjacketed cables for general purpose, determining the functional relationship between the measurand y (output quantity) and other quantities (input quantities) x₁, x₂, x₃……x_N. The uncertainty of the measurement result Y depends on the uncertainties of the input quantities x₁, x₂, x₃……x_N and their propagation law.

Comprehensively sort out and confirm the sources of uncertainty of the input quantities x from aspects including measuring instruments, measurement environment, measurement personnel, and measurement methods. The standard uncertainty u(x) of each input quantity shall generally be evaluated one by one in the order of x₁, x₂, x₃……x_N, and then the individual standard uncertainties u(x) are combined to form the final overall uncertainty.
