BSI BS ISO 3058:1998

Non-destructive testing. Aids to visual inspection. Selection of low-power magnifiers

PUBLISH DATE 1998
BSI BS ISO 3058:1998

1.1 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:

    1. binocular, normally with a long working distance (Type C.1);

    2. bi-ocular1), 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).

1.2 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.
