Optics and photonics — Environmental requirements — Part 1: General overview, terms and definitions, climatic zones and their parameters
ISO 10109-1:2005 is applicable to optical instruments and instruments with optical components. It specifies the requirements to be met with regard to the reliability of the optical, mechanical, chemical and electrical properties or performance characteristics of the instruments when exposed to environmental influences. Hence it also determines geographical and technical areas of application. Environmental test methods, as specified in ISO 9022 (all parts), are assigned to the various areas of application for the purpose of ascertaining the suitability of the instruments in the respective area of application. ISO 10109-1:2005 does not deal with the requirements to be met by the packaging of the instruments during transport from the manufacturer to the user.

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 10109-1 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 1,
Fundamental standards.
This second edition cancels and replaces the first edition (ISO 10109-1:1994), to which a new Clause 6,
Classification of instruments, has been added and the former Clause 6 (now Clause 7), Environmental
requirement designation, has been substantially revised.
ISO 10109 consists of the following parts, under the general title Optics and photonics — Environmental
requirements:
— Part 1: General overview, terms and definitions, climatic zones and their parameters
— Part 4: Test requirements for telescopic systems
— Part 6: Test requirements for medical optical instruments
— Part 7: Test requirements for optical measuring instruments
— Part 8: Test requirements for extreme conditions of use
— Part 11: Optical instruments for outdoor conditions of use
— Part 12: Conditions of transport for optical instruments

INTERNATIONAL STANDARD ISO 10109-1:2005(E)
Optics and photonics — Environmental requirements —
Part 1:
General overview, terms and definitions, climatic zones and
their parameters
1 Scope
This part of ISO 10109 is applicable to optical instruments and instruments with optical components. It
specifies the requirements to be met with regard to the reliability of the optical, mechanical, chemical and
electrical properties or performance characteristics (see Note) of the instruments when exposed to
environmental influences. Hence it also determines geographical and technical areas of application.
Environmental test methods, as specified in ISO 9022 (all parts), are assigned to the various areas of
application for the purpose of ascertaining the suitability of the instruments in the respective area of
application.
This part of ISO 10109 does not deal with the requirements to be met by the packaging of the instruments
during transport from the manufacturer to the user.
NOTE For the purposes of this part of ISO 10109, nominal values for properties or performance characteristics are
understood to be the technical data provided by the manufacturer, technical conditions of delivery or instrument standard.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
environmental requirements
specific natural and technical environmental influences, between the limiting values of which optical
instruments and instruments with optical components are to be operable
2.2
technical requirement
defined limiting value for the natural and technical environmental influences occurring in the envisaged area of
application
NOTE In order to verify whether an instrument fulfils a technical requirement, conditioning methods can be stipulated
with degrees of severity whose limiting values are either higher or lower than those specified.
2.3
extent of testing
sum of all required tests with which the operability of an instrument is ascertained under environmental
influence
NOTE The extent of testing is subdivided into type (or sample) testing and series testing.

ISO 10109-1:2005(E)
2.3.1
type testing
sample testing
extent of testing required of initial or qualification samples sufficient to ascertain reliably whether the
instrument complies with all the environmental requirements of the relevant specification
NOTE Type (or sample) testing is designated by the code letter T in other parts of ISO 10109.
2.3.2
series testing
extent of testing required to ensure constant production quality
NOTE 1 Sampling procedures can be used.
NOTE 2 Series testing is designated by the code letter S in other parts of ISO 10109.
2.4
severity of testing
number of specimens per production batch/series or sample production to be subjected to a specific test
NOTE The severity of testing is stipulated in the relevant specification or in the instrument standard.
2.5
suitability index
classification of the operability of an instrument within a standard climate
NOTE The values given in the comments of Tables 1 to 6 are not taken into account.
3 Climatic environmental influences
This clause classifies and describes six standard climates (see Tables 1 to 6), which constitute a summary of
the various major climatic environmental influences which are of significance for the use of optical instruments.
The values for standard Climates 1 and 2 have been compiled from excerpts of IEC 60721-2-1 and
IEC 60721-3-4.
Technical standard Climate 5 is defined for use in weather-protected locations.
Standard Climate 6 is defined as an open-air climate with restricted limiting values for optical precision
measurements and for the use of optical consumer products in the open air.
3.1 Standard Climate 1
Table 1 — Non-weather-protected locations with cold or
extremely cold climates (Arctic or Antarctic climate)
Environmental influence Value Comment
Temperature −65 °C to +35 °C In extreme geographical conditions, temperatures as low as −75 °C
and as high as 40 °C can occur in the location of use. With
temporary or permanent storage in enclosed vehicles, sheds,
hangars or attics, temperatures of over 35 °C can be experienced
in strong sunshine, and over 70 °C in extreme cases.
Relative humidity up to 100 % At a relative humidity of W 95 %, the maximum temperature
occurring is 20 °C.
Air pressure 70 kPa to 106 kPa 50 kPa to 110 kPa in unfavourable conditions.
2
Solar radiation up to 1,1 kW/m Intensity of global radiation on earth's surface.
Amount of precipitation (rain, u 15 mm/min
snow or hail)
Dew or ice build-up yes

Environmental influence Value Comment
Temperature −33 °C to +55 °C In extreme geographical conditions, temperatures as low as −45 °C
and over 60 °C can be experienced in the location of use. With
temporary or permanent storage in enclosed vehicles, sheds,
hangars or attics, temperatures of over 55 °C can occur in strong
sunshine, and over 85 °C in extreme cases.
