This part of IEC 62599 specifies the tests and severities to be used for each of the following environmental classes:

I Indoor but restricted to residential/office environment (e.g living rooms and offices)

(e.g sales floors, shops, restaurants, stairways, manufacturing and assembly areas, entrances and storage rooms)

III Outdoor but sheltered from direct rain and sunshine, or indoor with extreme environmental conditions (e.g garages, lofts, barns and loading bays)

Classes I, II, III and IV are progressively more severe, and therefore class IV equipment may be used in class III applications, etc

Classes III and IV can be modified with the suffix "A" to create environmental classes IIIA and IVA, specifically designed for the extremely cold conditions in northern Europe These classes maintain the same specifications as their counterparts, with the primary distinction being the conditioning temperature for cold environments.

Testing for Classes IIIA and IVA will follow the same procedures as Classes III and IV, with the exception of the operational and temperature change tests These specific tests will utilize a lower conditioning temperature as specified in the relevant tables (refer to section 10.3.4).

Unless otherwise specified, the atmospheric conditions in the laboratory shall be the standard atmospheric conditions for measurements and tests, specified in 5.3.1 of IEC 60068-1:1988, as follows:

– air pressure: 86 kPa to 106 kPa

To ensure accurate measurements, it is crucial to minimize variations in parameters that significantly impact the results during a series of tests conducted on a single specimen.

Unless otherwise stated, the tolerances for the environmental test parameters shall be as given in the basic reference standards for the test (e.g the relevant part of IEC 60068-2)

7 Information to be included in the relevant product standard

To conduct environmental tests, the relevant product standard must include essential information such as the equipment class (fixed, movable, or portable), the mounting arrangements for the specimen, any deviations from the specified test procedures or severities, initial measurements or inspections required before conditioning (like a functional test), and the necessary state of the specimen during conditioning, including its configuration and operating conditions.

This document is licensed to Mecon Limited for internal use at the specified locations in Ranchi and Bangalore, and is supplied by the Book Supply Bureau It outlines the necessary monitoring, measurements, and inspections required during the conditioning process, including functional tests when applicable Additionally, it details the final measurements and inspections to be conducted post-conditioning, such as functional tests and visual inspections, along with any special recovery conditions needed prior to these assessments The document also specifies the pass/fail criteria and provides a test schedule that allocates specimens to each test.

The purpose of environmental testing is to ensure that equipment operates correctly in its intended environment and continues to do so over a reasonable period However, alarm system hardware is installed in a wide range of environments, making it nearly impossible to test every aspect related to the most extreme environmental conditions.

The tests and severity levels outlined in this section of IEC 62599 are designed to provide a series of feasible assessments to determine the equipment's ability to withstand the most likely mechanical failures in its intended environment, typically found in industrial and commercial settings It is important to note that additional precautions may be necessary for specific installations where certain environmental factors may be identified as unusually severe A particular additional severity level has been incorporated into the cold test to address the unique cold conditions encountered in the extreme northern regions of Europe.

These tests are designed to demonstrate defects arising from realistic usage environments However, significant failures often result from gradual changes under actual operating conditions To conduct these tests within reasonable timeframes and at lower costs, it may be necessary to accelerate these changes by intensifying conditions, such as increasing the level of an environmental agent or extending its duration or frequency of application.

Les essais contenus dans la présente norme sont par conséquent divisés en deux types d’essai:

In these tests, the sample is subjected to conditions that mimic its intended operating environment The purpose of these tests is to demonstrate the equipment's ability to withstand and function correctly under normal usage conditions, as well as to show its immunity to specific aspects of that environment Consequently, the sample is operational, its conditions are monitored, and it can be functionally tested during the evaluation process related to these tests.

In these tests, the sample is subjected to more severe conditions than those encountered in normal usage to accelerate the effects of the typical operating environment The purpose of these tests is to demonstrate the materials' ability to withstand the long-term effects of the operating environment Since the test aims to study residual effects rather than immediate effects, the sample is typically not powered or controlled during the testing period.

This standard serves as a foundational document for environmental testing, which can be referenced in specific product standards for alarm system components within this application area To ensure consistency among these standards, working groups developing specific product standards should select the recommended tests and severity levels for the appropriate classes of equipment and environment, unless there are valid technical reasons to deviate.
