What is BS EN 843-1 - Mechanical properties of monolithic ceramics at room temperature about?
BS EN 843-1 is a European standard that discusses the determination of flexural strength of advanced monolithic technical ceramic materials.
BS EN 843-1 specifies methods for determining the nominal flexural strength of advanced monolithic technical ceramic materials at ambient temperature. The available loading geometries are three- and four-point flexure, using rectangular section test pieces of two prescribed geometries: 20 mm support span (A) and 40 mm support span (B).
BS EN 843-1 applies to materials with grain size less than 200 μm.
The test prescribes four categories of surface finish applied to the test pieces:
- As fired or annealed after machining
- Standard finishing by grinding
- Standard finishing by lapping/polishing
- Machined using agreed grinding procedures and material removal rates
Note: This part of EN 843 differs from ISO 14704 (see Bibliography) in respect of span A (not included in the ISO version), the absence of the 30 mm span option, and the required use of a fully articulating test jig.
Who is BS EN 843-1 - Mechanical properties of monolithic ceramics at room temperature for?
BS EN 843-1 on the mechanical properties of monolithic ceramics at room temperature is useful for:
- Mechanical engineers
- Monolithic technical ceramic manufacturers
- Quality control and testing personnel
Why should you use BS EN 843-1 - Mechanical properties of monolithic ceramics at room temperature?
Flexural strength testing can provide valuable information on the quality of advanced monolithic technical ceramic materials at ambient temperature, which is why it is frequently used to compare specimens before and after cyclic weathering tests. Flexural strength testing determines the material's ability to resist failure when bending and a load is applied, which helps to establish the product's application compatibility and lifetime, as well as the end user's safety.
In this regard, BS EN 843-1 provides the requirements of apparatus, test sampling, test method, and procedure to determine the flexural strength of advanced monolithic technical ceramic materials.
As a result, complying with BS EN 843-1 can help demonstrate the performance, quality, and durability of advanced monolithic technical ceramic materials, thus determining whether or not they are fit for purpose.
