DIN EN 16984:2017-09 is the current European standard titled "Disc springs – Calculation". It replaces the older German standard DIN 2092 and serves as the technical foundation for designing, calculating, and predicting the performance of disc springs (also known as Belleville washers). Core Function & Scope
The standard provides engineers with the specific mathematical formulas needed to determine how a disc spring will behave under pressure.
Predictable Deflection: It allows for the precise calculation of how much a spring will compress under a specific load.
Fatigue Life Estimation: One of its most critical roles is providing a method to determine the minimum life cycle (fatigue life) of a spring before it fails under repeated loading.
Stacking Configurations: It defines how characteristics change when springs are stacked in parallel (increasing force) or series (increasing deflection). Key Technical Sections
The PDF document typically covers several essential design criteria:
Design Formulae: Includes equations for load/deflection, spring rate, and energy capacity.
Stresses: Defines critical stress points on the disc (Points I, II, III, and IV) used to predict where fatigue cracks might originate.
Friction Effects: Provides guidance on how friction between stacked springs alters the theoretical load/deflection curve.
Geometric Limits: Generally applies to springs where the ratio of outside diameter to thickness is between 16 and 40. How to Access the Standard

DIN EN 16984 is the German adoption of the European standard EN 16984:2018, titled "Glass in building – Structural Sealant Glazing – Requirements for test methods and general requirements for the assessment of the product."
This standard specifies the test methods and general requirements for evaluating structural bonding sealants used in glass façade construction. It is specifically designed for silicone-based structural glazing sealants used in four-sided and two-sided structural sealant glazing systems.
In simple terms, DIN EN 16984 dictates how manufacturers must test their products to prove that a structural sealant can safely transfer loads (wind, dead load, thermal movement) from the glass pane to the building frame — without any mechanical fixings.
No. ETAG 002 is a guideline for European Technical Approval (ETA), while EN 16984 is a harmonized test standard. ETAG 002 is being phased out in favor of EN 16984 for CE marking purposes. However, many older projects still reference ETAG 002.
