1 This International Standard specifies the characteristics of the following types of low-power magnifiers and gives recommendations for their selection for the inspection of surfaces. — Single-element magnifiers of magnification typically up to ×4 (Type A). — Multi-element magnifiers of magnification typically up to ×10 (Type B). — Twin-system magnifiers of magnification typically up to ×15 (Type C), categorized as follows: a) binocular, normally with a long working distance (Type C.1); b) bi-ocular, including those refined with stops or other attachments, for quasi-stereoscopic vision (Type C.2). — Concave-mirror magnifiers with front-surface reflectors in powers typically up to ×6 (Type D). 2 This International Standard is not concerned with: — watch-makers' loupes and spectacles; — single-element, spherical- or cylindrical-lens magnifiers in which either the lens or the lens-mount rests on the surface of the object to be examined (this includes magnifiers provided with any form of graduated scale for the purpose of measurement); — plastic lens sacs, liquid-filled; — magnifiers intended for the examination of internal surfaces.
