New parameters to help define product requirements


​Do you know what kinds of stresses your product will be subject to when you send it out into the world? How do you ensure that your product arrives intact? And that it will function reliably throughout its lifecycle? The updated standards will help you define the various parameters for conditions during both transportation and use.

Environmental conditions refer to the prevailing physical and chemical conditions that a product is exposed to. 

Updated standards for environmental conditions

VTT Expert Services is on the international standard committee IEC TC104 (ENVIRONMENTAL CONDITIONS, CLASSIFICATION AND METHODS OF TEST), which is updating the standards governing the environmental conditions used to define product requirements.

IEC 60721-2 Environmental Conditions contains information about naturally occurring environmental conditions. These standards have been completely updated. 

IEC 60721-3 Environmental Classification classifies environmental conditions for specific applications on the basis of their parameters. Revision of these standards is currently ongoing.

IEC 60721-2-1 …9

Environmental conditions​
  • Temperature and humidity 
  • Precipitation and wind 
  • Air pressure 
  • Solar radiation and temperature
  • Dust, sand and salt mist 
  • Earthquake vibration shock 
  • Fauna and flora
  • Defining an environmental description from measured shock and vibration data: Storage, Transportation and In-use

IEC 60,721- 3-0 ...9

Environmental classification
  • Introduction
  • Storage 
  • Transportation
  • Stationary use, weather-protected 
  • Stationary use, Non-weather-protected 
  • Ground vehicle installations
  • Ship environment 
  • Portable and Non-stationary use 
  • Microclimates inside products 


Basic analysis of parameters has been carried out by two working groups:

  • WG 14 - Climatic field data including validation
  • WG 15 - Dynamic field data including validation


Both groups have published technical reports in the IEC/TR62130 and IEC/TR62131-x series. These contain up-to-date information about, for example, global climate conditions and the dynamic stresses that products are subject to during transportation, storage and handling. 

Testing ensures product durability

Standards provide a framework for the types of stresses that products must withstand. Product design must always be based on the environmental conditions that a product will be subject to during its lifecycle.

In practice, the product's durability is verified through testing. A product-specific test plan is drawn up to ensure that the product meets the requirements set by the standards.

We evaluate the impact of environmental stresses on a product using a variety of heat, moisture and corrosion tests, and vibration and shock testing.
