ISO 15362:2014

Overview

ISO 15362:2014 - "Stereomicroscopes - Information provided to the user" specifies the minimum manufacturer information that must be supplied with stereomicroscopes. The second edition (2014) replaces the 1998 edition and defines mandatory (m) and recommended (r) data items that appear in product documentation, labels and specification sheets. The format of the data is referenced to ISO 11883 (marking of stereomicroscopes).

Key Topics and Requirements

ISO 15362 focuses on clear, standardized user information for stereomicroscopes. Key technical topics include:

• General manufacturer data

  • (m) Manufacturer identification
  • (r) Country of origin and other origin details when applicable

• Optical performance (mandatory)

  • (m) Magnification
  • (m) Zoom range or number of discrete steps
  • (m) Object field diameter
  • (m) Free working distance (see Figure 1 in the standard)
  • (r) Numerical aperture (recommended)

• Main body and tube

  • (m) Binocular or trinocular tube designation
  • (m) Interpupillary distance adjustment range (mm)
  • (m) Viewing inclination angle
  • (r) Dioptre adjustment, exit pupil distances, tube lens focal length

• Objectives and eyepieces

  • Objectives (if removable/switchable): (m) magnification or focal length, (m) free working distance
  • Eyepieces: (m) magnification, (m) field number; (r) graticule interchangeability, spectacle-wear suitability, dioptre adjustment

• Stand and accessories

  • (r) Stand/base dimensions, distance from optical axis to column, overall mechanical height, focus drive range
  • (m)/(r) Effects of accessories on basic data and a list of available accessories and usage restrictions

The standard distinguishes mandatory versus recommended information so manufacturers and technical writers can prioritize essential user data.

Applications and Who Uses This Standard

ISO 15362 is practical for:

• Manufacturers and product designers producing user manuals and spec sheets for stereomicroscopes.
• Technical writers and regulatory teams preparing compliant documentation and labels.
• Procurement and quality managers comparing microscope specifications during purchasing or acceptance testing.
• Laboratories, educational institutions and industrial inspection teams that rely on consistent, comparable instrument information for selection and safe operation.

Common use cases: product datasheets, user manuals, compliance checks, marketing specification tables, and technical comparison charts.

Related Standards

• ISO 11883 - Optics and optical instruments - Microscopes - Marking of stereomicroscopes (normative reference used for data format).
• ISO/TC 172/SC 5 is the technical committee responsible for microscope standards (informative).
