Overview

ISO 11884-1:2006 specifies minimum requirements for stereomicroscopes for general use, intended mainly for visual observation. Published by ISO (Technical Committee ISO/TC 172, Subcommittee SC 5), this second edition defines baseline optical, mechanical, environmental and safety criteria that manufacturers, test laboratories and purchasers can use to ensure consistent performance of stereomicroscopes used in industry, education and routine laboratory work.

Key topics and requirements

• Optical and mechanical specifications

  • Defines tolerances for total magnification (e.g., ±10 %) and alignment between left and right optical channels.
  • Specifies interpupillary distance range (55 mm to 75 mm) and requirements for focus, image centering and imaging rotation.
  • Resolution and depth-of-field test conditions are defined (e.g., measured in the centre of the field with a 10× eyepiece at 0 D).
  • Testing methods for optical/mechanical parameters reference ISO 15227.

• Environmental conditions

  • Sets operating (use), storage and transport condition limits (temperature, relative humidity, atmospheric pressure, shock and vibration).
  • Examples: operating temperature typically 10 °C to 40 °C; storage and transport extremes are defined with specific shock and vibration profiles.
  • Environmental tests and conditioning procedures reference parts of ISO 9022.

• Safety and compliance

  • Electrical and laboratory-safety requirements are covered by IEC 61010-1.
  • Marking and labeling requirements reference ISO 11883.

• Testing and documentation

  • All specified tests are type tests; statistical evaluation rules apply.
  • Stereomicroscopes must be supplied with instructions for use, cleaning and maintenance.

Applications and who uses this standard

• Manufacturers - to design and validate stereomicroscopes that meet recognized minimum performance and environmental robustness.
• Test and calibration laboratories - to run type tests and certify compliance using ISO 15227 and ISO 9022 methods.
• Procurement and quality managers - to specify minimumacceptance criteria for purchasing and incoming inspection.
• Educational and industrial labs - to select reliable instruments for routine visual inspection, quality control, teaching, and assembly tasks.

Related standards

• ISO 15227 - Testing of stereomicroscopes (optical/mechanical test methods)
• ISO 9022 (series) - Environmental test methods for optics and optical instruments
• IEC 61010-1 - Safety requirements for electrical equipment for laboratory use

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11884-1 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 5,
Microscopes and endoscopes.
This second edition cancels and replaces the first edition (ISO 11884-1:1998), which has been technically
revised.
ISO 11884 consists of the following parts, under the general title Optics and photonics — Minimum
requirements for stereomicroscopes:
⎯ Part 1: Stereomicroscopes for general use
⎯ Part 2: High performance microscopes
