Einführung
ISO (Internationale Standardisierungsorganisation) ist eine globale Allianz nationaler Normungsgremien (ISO-Mitgliedsorganisationen). Die Entwicklung internationaler Standards erfolgt in der Regel durch technische Komitees der ISO. Jede Mitgliedsinstitution, die an einem Thema interessiert ist, zu dem ein Fachausschuss eingerichtet wurde, hat das Recht, in diesem Ausschuss vertreten zu sein. An dieser Arbeit sind auch internationale Regierungs- und Nichtregierungsorganisationen beteiligt, die mit der ISO zusammenarbeiten. ISO arbeitet eng mit der International Electrotechnical Commission zusammen (IEC) in allen Fragen der elektrischen Normung.

Die Verfahren zur Erstellung dieses Dokuments und zur weiteren Wartung werden im Teil beschrieben 1 der ISO/IEC-Richtlinie. Insbesondere, Es sollte auf die unterschiedlichen Genehmigungskriterien geachtet werden, die für verschiedene Arten von ISO-Dokumenten erforderlich sind. This document has been drafted in accordance with the editing rules of ISO/IEC Directive Part 2 (siehe iso.org/directives).

Bitte beachten Sie, dass bestimmte Elemente dieses Dokuments möglicherweise Patentrechten unterliegen. ISO ist nicht dafür verantwortlich, einige oder alle dieser Patente zu identifizieren. Details of any patent rights identified during the preparation of the document will be found in the introduction and/or in the list of patent claims received by ISO (siehe iso.org/patents).

Optical instruments are subject to many different environmental parameters during use, which need to be resisted without significantly degrading performance and remaining within prescribed specifications.

The type and severity of these parameters depend on the conditions under which the instrument is used (Zum Beispiel, in a laboratory or workshop) and its geographical location. The environmental effects on the performance of optical instruments in tropical and subtropical regions are completely different from those found when used in the Arctic. Each parameter will have different overlapping effects on the performance of the instrument.

Manufacturers try to ensure that, naturally, users expect the instrument to be resistant to the rigors that its environment can bring throughout its life cycle. This expectation can be assessed by exposing the instrument to a range of simulated environmental parameters under controlled laboratory conditions. The severity of these diseases is often increased in order to achieve meaningful results in a relatively short period of time.

To evaluate and compare the response of optical instruments to appropriate environmental conditions, ISO 9022 contains detailed information on many laboratory tests that reliably simulate a wide range of different environments. These tests are mainly based on IEC standards, modified if necessary to take into account the special functions of the optical instrument.

ISO 9022-11-2015 – Umweltprüfmethoden für Optiken und optische Instrumente – Teil 11: Schimmelbildung

Due to the continuous progress in various fields, optical instruments are no longer just precision designed optical products, but also contain other components from other fields, depending on their range of application. daher, the main functions of the instrument will be evaluated to determine which international standard should be used for testing. If optical functions are important, then ISO 9022 is applicable, but if other functions take precedence, then appropriate international standards in the relevant fields should be applied. There may be situations where ISO 9022 and other appropriate international standards need to be applied simultaneously.

Although the species of fungus chosen for testing is generally not harmful to humans, some people may experience allergies or other reactions. Experienced and trained personnel need to be used to ensure the fungus is handled correctly and tested properly. daher, it is recommended that the test performance required in this part of ISO 9022 be delegated to microbiology laboratories, as such laboratories have the appropriate equipment and trained personnel.

1 Reichweite
Dieser Teil von ISO 9022 specifies methods related to environmental testing of optical instruments, including other components from other fields (such as mechanical, chemical and electronic equipment) under equal conditions to resist the effects of mold growth.

ISO 9022-11-2015 – Umweltprüfmethoden für Optiken und optische Instrumente – Teil 11: Schimmelbildung

Jedoch, complete instruments or components are only tested in exceptional circumstances in accordance with this part of ISO 9022. Typischerweise, representative samples (such as mounted optical components, material samples, or surface coatings on representative samples) are used for testing.

The tests described in this part of ISO 9022 are designed to select materials and components for instruments that may be used in environments conducive to mold growth, rather than for conventional production control.

The purpose of the test is to investigate the extent to which the optical, climatic, mechanisch, chemisch, and electrical (including electrostatic) performance characteristics of the specimen are affected by mold growth.

Zusätzlich, the tests in this part of ISO 9022 are designed to assess the extent to which metabolic wastes excreted by fungi, such as enzymes or acids, cause etching, corrosion, or short circuits, such as in printed circuit boards.
