Increases load capacity while keeping deflection the same as a single spring.
Works in conjunction with DIN EN 16983 (formerly DIN 2093), which specifies the actual dimensions and materials of the springs. Origin: Prepared by the European Spring Federation (ESF). 2. Scope of the Standard
The core utility of DIN EN 16984 lies in its ability to accurately predict how a conically-shaped spring reacts under an axial load. Unlike traditional helical wire springs, a disc spring generates substantial force within a highly restricted physical footprint. 1. Non-Linear Load and Deflection behavior
: 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. din en 16984 pdf
Calculating disc spring behavior requires assessing inner/outer diameters, material thickness, and overall cone height. Application Description Decap D sub e Outer edge measurement defining boundary envelope. Inside Diameter Dicap D sub i Inner core diameter clear of guiding shafts. Material Thickness Base thickness dictating total load stiffness. Cone Height Total internal compression travel limit available. Calculated Stress Yield and fatigue stress limits at critical points.

The standard explicitly covers:
When purchasing, ensure you look for the most current revision or check if any amendments (A1, A2, etc.) have been added to guarantee full compliance with the latest European Machinery Directive requirements.
Environmental, Health, and Safety (EHS) managers use the standard to vet third-party cleaning equipment before purchase. Confirming a vendor conforms to DIN EN 16984 reduces workplace injury liability and ensures a safer environment for cleaning staff. How to Access a Legitimate Copy of DIN EN 16984
Multiple isolation barriers are required for high-risk gases. Proof-of-closure switches must verify valve positions. 2. Combustion Air and Venting Systems must monitor air-to-fuel ratios continuously. Purging cycles must clear the chamber before ignition. Increases load capacity while keeping deflection the same
Defines design stresses at five critical points on the disc (designated as OM, I, II, III, and IV) to ensure structural integrity. Stacking Rules:
Disc springs designed according to this standard are used in various industries where high load capacity, high fatigue life, and compact design are required:
