The reliability and quality of today’s highly sensitive electronic products is significantly influenced by the compliance with rules of protection against electrostatic charges. For your orientation, international standards are recommended.
The IEC61340 series of standards provides basic answers to questions about ESD protection. Here we present the most important standards:
Electrostatics Part 2 general test methods:
IEC61340-2-1 Process method – ability of materials and products to discharge electrostatic charges
IEC 61340-2-3 test method for determining the resistance and resistivity of solid planar materials used to avoid electrostatic charge
Electrostatics Part 3 models:
IEC61340-3-1 method for simulation of electrostatic discharges: Human Body Model (HBM) Component Testing
IEC 61340-3-2 method for simulation of electrostatic discharges: Machine Model (MM) Component Testing
Electrostatics Part 4 special test methods:
IEC61340-4-1 Fixed test methods for specific applications section 1: Electrostatic behaviour of floor coverings and installed floors
IEC 61340-4-3 Standard test methods for specific applications – Footwear
IEC 61340-4-5 Standard test methods for specific applications – Methods for characterising the electrostatic protection of footwear and flooring in combination with a person
IEC 61340-4-6 Standard test methods for specific applications – wrist straps
IEC 61340-4-7 Standard test methods for specific applications – ionisation
IEC 61340-4- Standard test methods for specific applications – electrostatic discharge shielding – Bags
IEC 61340-4-9 Standard test methods for specific applications – clothing
IEC 61340-4-10 Tests for the protection of electrostatic sensitive devices – two-point resistance measurements
Electrostatics Part 5 general requirements:
EN 61340-5-1 Protection of electronic devices from electrostatic phenomena – General requirements
DIN EN 61340-5-1 Supplement 1, Part 5-2 Protection of electronic devices from electrostatic phenomena – User guide
DIN EN 61340-5-3 Properties and requirements classifications for packaging which can be used for components that are sensitive to electrostatic discharge.
What are standards, what are they for and who makes them?
Norms define standards and greatly facilitate national and international trade.
Standards are voluntary agreements between those who formulate them.
In Germany, standards govern over 80% of technical details of products or processes.
Technical standards define requirements such as dimensions, weights, tolerances and measurement methods.
Standards represent the current state of the art and the ergonomic findings (which themselves can change.) They include mandatory rules or recommendations.
More recently, management systems, such as operational quality management or rules of organizational work design are also being standardised.
The German Institute for DIN Standardisation is the most prominent organization for standardisation in Germany since 1975 by contracting with the Federal Government.
DIN is obliged to apply the European standards (DIN EN). International standards such as ISO do not apply in Germany, except where adopted by DIN.
The International Electrotechnical Commission IEC is the oldest international organisation for standardisation which develops the standards in the field of electrical engineering and therefore many product standards that are relevant for occupational safety and health. The national standardisation bodies from some 130 countries work together in the International Organization for Standardisation ISO. Their work follows a similar pattern as that of DIN due to its principle of voluntary action. Similar to the DIN standards, ISO standards are also created largely based on the principle of consensus.
Further standardisation institutions based on international cooperation are ITU (International Telecommunication Union), CIE (International Commission on illumination), IAEA (International Atomic Energy Agency) ILO (International Labour Office) and WHO (World Health Organization).
The European standardisation bodies
Enhanced European cooperation in 1957 led to the creation of the European Commission for Standardization CEN and the European Electrotechnical Standardization Committee of CENELEC, which are located in Brussels together with the European Institute for Standardization for Telecommunications, ETSI. In CEN, the national standards organisations of all EU and EFTA countries are represented.
Harmonised technical standards for the single market
The objective of European standardisation is to contribute to fulfilling the essential safety objectives of the EU directives on the harmonisation of the market pursuant to Article 100a EWG Treaty. Here you will find requirements relating to construction and equipment, such as the Machinery Directive.
The harmonised EU standards specify the guidelines and contain descriptions of possible technical solutions. The level of security throughout Europe should be established through voluntary adherence to recognised standards
European standardisation is based on the international standards. European standards should be taken up into national standards, i.e. DIN (DIN, EN).
Mission of the EU Commission
The harmonised standards are created by order of the European Commission (mandate) of the European standardisation bodies and then ratified. However, requests for standardisation can also be made by individuals.
European Standards (EN) are non-binding, and manufacturers, for example, do not have to observe them. At the same time, thanks to compliance with the standards the basic safety requirements of a directive are met.
A manufacturer’s product is then EN compliant. A CE mark can be applied and the product may be freely marketed within the EU. For consumers, EN provides protection and strengthens confidence in products and services.
In the German-speaking area the ESD Forum e.V. offers annual meetings as a basis for the exchange of interested parties.
