Glass in construction Part 4
DIN 18008-4 is a standard that deals with the design and construction of fall-protection glazing. This standard specifies how glass must be used in construction to ensure safety against falls. It includes requirements for static and dynamic loads as well as safety measures to prevent glass breakage under load.
hardware for Lift&Slide windows and Lift&Slide window doors
The standard EN 13126-16 deals with hardware for Lift&Slide sash windows and Lift&Slide sash French doors. It defines requirements and test methods relating to the durability, strength, and protective function of this hardware. The properties of the hardware are expressed by a nine-digit classification code, similar to other parts of the EN 13126 series.
Series of standards for burglar-resistant building products
The standards EN 1627 to EN 1630 address burglary resistance of windows, doors and closures. They specify the requirements, classifications and test methods for products intended to protect against burglary attempts.- EN 1627 defines the general requirements and classifications.
- EN 1628 describes the test method for determining resistance under static load.
- EN 1629 covers the test method for determining resistance under dynamic load.
- EN 1630 focuses on the test method for determining resistance against manual burglary attempts.
These standards are crucial for construction products used in security-relevant areas.
air permeability
The EN 12207 standard refers to the classification of air permeability of windows and doors. It defines how much air can pass through a closed window or door under certain conditions. The test is carried out by applying pressure differences across the product to measure its air tightness. These measurements are important for assessing the energy efficiency and comfort in buildings.
driving rain tightness
DIN EN 12208 is a European standard that deals with the classification of watertightness for windows and doors. It specifies how much water can penetrate a closed window or door under certain conditions. The test involves applying water pressure to the external surface of the product to assess its ability to prevent water ingress. This assessment is important for protection against moisture damage and to ensure energy efficiency in buildings.
resistance to wind load
The DIN EN 12210 standard relates to the resistance of windows and doors to wind loads. It specifies how these building components must be tested under various pressure conditions to assess their ability to withstand wind loads. These tests are crucial for ensuring the safety and stability of buildings during strong winds or storms.
SKG resistance class 3
Products with SKG class 3 certification offer the highest protection against burglary attempts. This classification is ideal for areas exposed to particularly high security risks.Features of SKG class 3:
- Resistance time: These products withstand forced entry attempts for a longer period and thus provide significant resistance.
- Application area: Suitable for residential buildings, commercial properties, or other objects where a high level of security is required.
barrier-free construction
The DIN 18040 standard deals with the planning principles for barrier-free construction. It is divided into different parts that cover various aspects of construction to enable people with disabilities, elderly persons, and children to participate equally in everyday life. An important aspect of this standard is the easy opening of doors without external assistance. In this context, requirements are placed on door closers, such as limiting the operating forces to ensure that doors are easily accessible.
