BS ISO 14997:2017规定了实施表面缺陷评估方法的物理原理和实用方法。对于使用可见性方法规定的缺陷，描述了两种检查方法。第一种是在没有任何比较标准（IVV）的情况下对表面进行视觉评估。第二种方法是与已知亮度（ISV）的人工制品相比，对表面缺陷进行可见性评估。对于使用尺寸法规定的缺陷，描述了三种方法。第一种是在没有任何比较标准（IVD）的情况下对表面进行视觉评估。第二种是与已知尺寸的人工制品（ISD）相比，对表面缺陷进行尺寸评估。第三种是使用放大率和已知尺寸的比较人工制品或十字线或标尺（IMD）对表面缺陷进行尺寸测量。 存在能够客观测量亮度（数字散射计）或尺寸（数字显微镜）的仪器。虽然这些仪器可用于评估表面缺陷，但它们超出了本文件的范围。本文件适用于双绞线或三绞线等部件或组件的光学表面。本文件适用于光学塑料组件；然而，需要注意的是，塑料材料的冲击损伤通常与较硬材料的冲击损伤非常不同，因为它并不总是导致材料的去除，而是会置换材料，导致表面产生波纹。因此，将塑料的划痕和挖掘损伤与玻璃或晶体材料的划痕和挖掘损伤进行目视比较，可以得出非常不同的结果。交叉引用:ISO 10110-7:2017ISO 9211- 1:2010 Ed 2ISO 11145:2016ISO/TR 21477:2017ISO 10110-1:2006（R10）Ed 2ISO 11151购买时可用的所有当前修订版均包含在本文件的购买中。

BS ISO 14997:2017 specifies the physical principles and practical means for the implementation of methods for evaluating surface imperfections.For imperfections specified using the visibility method, two inspection methods are described. The first is visual evaluation of the surface without any comparison standard (IVV). The second is a visibility assessment of a surface imperfection when compared to an artefact of known brightness (ISV).For imperfections specified using the dimensional method, three methods are described. The first is visual evaluation of the surface without any comparison standard (IVD). The second is a dimensional assessment of a surface imperfection when compared to an artefact of known size (ISD). The third is the dimensional measurement of a surface imperfection using magnification and either a comparison artefact of known size or a reticle or ruler (IMD).Instruments exist that allow objective measurement of brightness (digital scatterometry) or size (digital microscopy). While these instruments can be used for evaluation of surface imperfections, they are beyond the scope of this document.This document applies to optical surfaces of components or assemblies such as doublets or triplets.This document can be applied to optical plastic components; however, attention is drawn to the fact that impact damage to plastic materials often looks very different from that on harder materials as it does not always result in the removal of material but instead can displace material, causing ripples in the surface. Consequently, visual comparisons of scratch and dig damage to plastic with those on glass or crystalline materials can give very different results.Cross References:ISO 10110-7:2017ISO 9211-1:2010 Ed 2ISO 11145:2016ISO/TR 21477:2017ISO 10110-1:2006 (R10) Ed 2ISO 11151All current amendments available at time of purchase are included with the purchase of this document.
