ISO 3058:1998

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

PUBLISH DATE 1998
ISO 3058:1998

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 Ă—4 (Type A).
  • Multi-element magnifiers of magnification typically up to Ă—10 (Type B).
  • Twin-system magnifiers of magnification typically up to Ă—15 (Type C), categorized as follows:
    • binocular, normally with a long working distance (Type C.1);
    • 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 Ă—6 (Type D).

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.

1) The distinction between bi-ocular viewing and stereoscopic viewing is defined in annex A.
