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.
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.
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.
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.
