E‑Standard

E‑standards are norms specifically developed for electrical engineering and electronics. They are typically created by international and national standardization bodies such as the International Electrotechnical Commission (IEC), the European Committee for Electrotechnical Standardization (CENELEC), and the German Institute for Standardization (DIN). E‑standards define technical specifications, test procedures, and safety regulations for electrical and electronic products and systems.

Elastane

Elastane, also known by the brand name Spandex, is a synthetic fiber renowned for its exceptional elasticity and stretchability. It is commonly used in the textile industry to make clothing more comfortable and adaptable. Elastane is often blended with other fibers to enhance their wear characteristics.

Electric Screwdriver

Electric screwdrivers are powerful tools used for quickly and efficiently driving in and removing screws. They are widely used in both DIY and professional construction. Electric screwdrivers save significant time and reduce physical effort compared to manual screwdrivers.

Electrical Discharge Machining (EDM)

EDM, also known as spark erosion or electrical discharge machining, is a manufacturing process in which material is removed from a workpiece through electrical discharges. This method is commonly used to produce complex shapes and fine details in hard or difficult-to-machine materials.

Electroplating

Electroplating is an electrochemical process in which a thin metal layer is deposited onto a conductive workpiece. This process serves both to protect against corrosion and to improve aesthetic properties as well as increase surface hardness. Common metals used in electroplating include zinc, nickel, chromium, silver, and gold.

EN 397

DIN EN 397 defines the requirements for industrial safety helmets. This standard ensures that helmets meet specific quality and safety criteria to protect the wearer from falling objects, impacts, and other hazards.

Enamel

Enamel is a glass-like coating applied to metals, ceramics, and glass to create a decorative and protective surface. This coating is produced by applying and firing powdered glass at high temperatures. Enamel is known for its durability, hardness, and resistance, and is used in many industrial and artistic applications.

Engraving

Engraving is a surface processing technique where material is removed using mechanical, chemical, or laser-based methods to create a design, pattern, or inscription on a workpiece. It is commonly used in art, jewelry making, industry, and for decorative purposes.

Epoxy Resin

Epoxy resin is a versatile and widely used material applied in numerous industrial and craft applications. It is a thermosetting plastic composed of epoxy resin and a hardener. When cured, it forms a solid, highly durable structure.

Erosion

Erosion refers to the process by which soil, rock, or other surface materials are worn away and transported by natural forces such as water, wind, ice, or gravity. This process can significantly alter landscapes over long periods and plays a key role in geology and environmental science. Erosion can occur naturally or be accelerated by human activities.

Erosion Risk

Erosion risk refers to the likelihood that soil, rock, or other surface materials will be worn away by natural processes such as water, wind, or ice. This risk can be especially significant in agricultural, coastal, or mountainous regions and often leads to soil degradation, loss of fertile land, and habitat deterioration.

Expander

Expander tools are special instruments used to expand or stretch pipes, hoses, and other cylindrical objects. These tools are particularly useful in installation technology, metalworking, and vehicle repair. They allow for precise work and ensure secure, tight connections.

Explosion-Proof (Ex-Protected)

The term "ex-protected" refers to devices and equipment specifically designed to be safely operated in potentially explosive environments. These devices are constructed so that, under certain conditions, they do not act as an ignition source and therefore cannot ignite explosive atmospheres. "Ex-protected" stands for "explosion-proof" and is a key safety aspect in industries working with flammable gases, vapors, dusts, or liquids.

Extrusion

Extrusion is a manufacturing process in which material is pushed through a shaping opening, the die or nozzle, to create continuous shapes and profiles. This process is used in various industries, from plastics and metalworking to food production.

Extrusion

Extrusion is a continuous manufacturing process in which material is forced through a shaping opening, the die or nozzle, to produce products with a fixed cross-sectional profile. This process is used in various industries, including plastics, metalworking, and food production.
