2. Impact Absorption: EN 14404 sets requirements for the knee protector’s ability to absorb and distribute the force of impacts, reducing the risk of injury.
3. Penetration Resistance: The knee protector should offer resistance against sharp objects or edges that could potentially penetrate the material and injure the wearer’s knee.
4. Ergonomic Performance: The standard addresses the ergonomic aspects of knee protectors, including comfort, ease of use, and potential interference with the worker’s movements.
5. Testing Methods: EN 14404 provides detailed testing procedures to evaluate the knee protector’s performance in terms of impact absorption, penetration resistance, and other relevant factors.

Knee protectors that meet the requirements of EN 14404 are often labeled as conforming to this standard. This label indicates that the knee protectors have undergone testing to ensure they meet the established criteria for protection and comfort during kneeling work.

As with any standard, it’s important to consult the latest version of EN 14404 or any relevant updates to ensure accurate and up-to-date information, as standards can change over time.

IEC 61482 is an international standard that pertains to protective clothing designed to provide protection against the thermal hazards of an electric arc. The title of the standard is “Live working – Protective clothing against the thermal hazards of an electric arc.” It falls under the domain of electrical safety and personal protective equipment (PPE).

Electric arcs can generate intense heat and energy, which can pose significant hazards to workers in industries where electrical systems are present, such as power generation, distribution, and maintenance. IEC 61482 aims to ensure that protective clothing worn by workers in these industries provides effective protection against the thermal hazards associated with electric arcs.

The standard outlines two different methods for testing and classifying protective clothing:

1. Box Test Method (IEC 61482-1-1): This method involves exposing a fabric sample to an electric arc in a controlled environment. The fabric is tested to determine its arc rating, which indicates the level of thermal protection it provides against the energy generated by an electric arc. The arc rating helps in categorizing the fabric’s ability to protect the wearer.
2. Open Arc Test Method (IEC 61482-1-2): This method simulates a real-world scenario where the clothing is worn by a mannequin that is exposed to an electric arc. The arc exposure generates heat and energy similar to an actual electrical fault. This method assesses the garment’s performance in a more realistic setting.

The results of these tests lead to the classification of protective clothing into different categories, which provide information about the level of protection they offer against electric arcs. These categories include:

• Class 1: Clothing providing protection against electric arc exposure with an arc rating of at least 4 kA (kiloamperes).
• Class 2: Clothing providing protection against electric arc exposure with an arc rating of at least 7 kA.
• Class 3: Clothing providing protection against electric arc exposure with an arc rating of at least 25 kA.

Manufacturers use these classifications to indicate the level of protection offered by their garments against electric arc hazards.

It’s important to note that standards can be updated or revised, so it’s recommended to consult the latest version of IEC 61482 or any relevant updates to ensure accurate and up-to-date information.
