IEC EN 60721-3-0 Classification of Environmental Conditions - Part 3-0: Classification of Environmental Parameter Groups and Severity - Introduction

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60721-3-0 testing. IEC EN 60721-3-0 provides guidance on the use of all parts of IEC EN 60721-3. Contains background information on the application and limitation of classes given in various parts of IEC EN 60721-3 that can be used in the design, limitation and protection of equipment.

A product may be exposed to a variety of environmental conditions during its lifetime. These conditions are divided into classes described in IEC EN 60721-3 (all parts). The given classes can be used to describe the maximum short-term environmental stresses of a product. However, they do not provide information on the long-term or total lifetime environmental stresses that a product may be exposed to. This means that no reliability or lifetime assessments are possible based solely on these classes.

A product will be simultaneously exposed to a number of environmental parameters, such as solar radiation and temperature, temperature and humidity, as well as vibration and temperature variation. Combinations of given environmental parameters can increase the impact on a product. Therefore, the combined conditions must be considered in the design and evaluation of a product.

Short-term extreme environmental conditions can occur at any time during the life of the product. While a product is not affected by an extreme situation when it is new, it may deteriorate when exposed to the same condition as the effect of aging after a long period of use. The order in which environmental conditions are applied can affect the results of an assessment.

When referring to a particular class in IEC EN 60721-3, it is important for the product specification to define whether the product must be able to function or only survive when exposed to conditions defined by the class without permanent damage. Environmental classes can be used as a basis for the selection of design and test intensities based on the outcome of the failure.
