OKHow much weight does a cardboard table actually need to be able to withstand? Can it match a conventional table in terms of stability?
We design sustainable furniture without compromises. Through strict quality controls and innovative constructions, we ensure that our furniture can withstand the demands of everyday use while offering a stylish and functional design. Testing the stability and load-bearing capacity of each piece of furniture is therefore an essential step in our product development. In addition to our own testing methods, we collaborate with professional and independent institutions, such as TÜV or Bureau Veritas, which test our furniture according to the relevant DIN standards to ensure their durability.
The standards defined by the German Institute for Standardization (DIN) provide a standardized framework for furniture in various categories and applications. These standards specify testing procedures to test the stability of furniture and ensure that they have the necessary load-bearing capacity. While there is no legal obligation to meet or even test the DIN standards, passing this test is, for us, the basic prerequisite for a piece of furniture to be sold in our store.
Since most people are probably unfamiliar with such testing procedures, we want to explain this process using the example of our GRID Table. Below, we outline the individual components of the testing based on the DIN EN 12521:2015 and DIN EN 1730:2012 standards, which determine the stability, strength, and durability of tables in residential areas.
To assess the stability and load-bearing capacity of the table under static load, a weight of 50 kg is placed exactly in the center of the tabletop. Then, a horizontal (lateral) force of 200 N (approximately 20 kg) is applied ten times in the center of each side of the tabletop using a pressure stamp.
This test reveals whether the table can withstand the demands of normal use without deforming or being damaged.
In this test, the durability and resilience of the table are put to the test. A weight of 50 kg is again placed exactly in the center of the tabletop. Then, a horizontal force of 300 N (approximately 30 kg) is applied laterally at one edge of the table using a pressure stamp. This process is repeated 10,000 times on each edge of the table to determine whether the table can withstand the typical stresses and strains of everyday home use without compromising its quality or stability.
In the vertical static load test, a vertically downward force of 1,000 Newtons (approximately 100 kg) is applied with a pressure stamp exactly in the center of the tabletop. This process is repeated ten times at the same spot to test the table's stability and its ability to withstand vertical loads.
The stability test under vertical load aims to ensure that the table remains stable and does not tip or give way when exposed to vertical loads. A pressure of 400 N (approximately 40 kg) is applied vertically downward using a pressure stamp at the center of the table edge.
The vertical impact test examines the table's response to sudden loads. For this, a pressure stamp with a weight of 25 kg is dropped ten times from a height of 14 cm onto the tabletop. The point of application of the pressure stamp is not placed closer than 10 cm from any edge of the table. This test ensures that the table does not tip, get damaged, or lose stability under such a load.
The presence of the GRID table in our shop already indicates that it has passed the standard testing — in this case, conducted by the independent certification company Bureau Veritas — and meets the quality criteria of the DIN standards EN 12521:2015 and EN 1730:2012.
And what if it hadn’t passed?
Then the first step would have been to optimize it. Small changes in the design can sometimes make a big difference without negatively affecting the design and functionality.
