ISO/TR 23697:2011适用于纺织品和纺织产品，仅涉及以连续规模运行以产生单一数字作为测试结果的测试方法。然而，这一数字可以是一组测量值计算的结果。 试验结果的分布要求为单峰分布，并假定为正态分布。对于非高斯分布，需要其他评估程序。 它不包括产生离散值的方法、“通过/失败”（通过/不通过）类型的结果、（接受/拒绝）测试或排名方案正在运行的方法。

ISO/TR 23697:2011 can be applied to textiles and textile products and is concerned only with test methods which operate in a continuous scale to yield a single numerical figure as the test result. However, this single figure can be the outcome of a calculation from a set of measurements. The distribution of test results is required to be unimodal and is assumed to be normal. With non-Gaussian distributions, other evaluation procedures will be necessary. It does not cover methods which yield discrete values, "pass/fail" (go/no go) type results, (accept/reject) tests or where a ranking scheme is in operation.
