In the CPSD-HL-01022-MTHD standard, developed within the scope of consumer protection and safety by Bureau Veritas, a global organization working in the fields of independent surveillance, inspection, certification and risk prevention of French origin, the requirements for a force applied to a chair or chair are explained and a test is performed. method is defined. At the end of the test, it is expected that the seat or chair will not tip over and deform under force.
In principle, no structural failure or permanent deformation is expected under side loading (136 cm) for adults weighing less than 62 kg and children weighing less than 16 kg per seat or chair.
While testing, 13 discs are placed in the seating area for type I and type II chairs. For a Type III chair, 6 discs are placed in the seating area. A horizontal force is then applied to the highest disc at a position 6 mm down from the top.
For seat or chairs whose height is less than 710 mm, the force is calculated as: F = 0.1964 (1195 - H) Newtons (H is seat height in mm). A constant force of 710 N is applied for chairs with a seat height equal to or greater than 93 mm.
In general, a stability test evaluates the possibility of the chair or chair tipping over during use. During the tests, specified forces are applied at certain points on the seat, arms and, if any, footrest and backrest. If the seat tilts forward, sideways, or backwards, or is deformed, the test is unsuccessful.
In most cases, sofas and chairs are tested against a specific national or international standard. Choosing which standard to use can sometimes be confusing. In some cases, the seat supplier or manufacturer seeks evidence that the seat or chairs are fit for purpose and safe. Especially when it comes to new designs, this need becomes more evident. Most standards are intended to demonstrate that the seats are suitable for persons weighing up to 110 kg. Therefore, seats that will be used by very heavy people need to be tested using increased forces.
Among the numerous tests, measurements, analyses, and evaluations our organization provides for businesses in various sectors, we also offer force application testing services under the CPSD-HL-01022-MTHD standard, utilizing a trained and expert staff and advanced technological equipment.
