In the CPSD-HL-01058-MTHD standard, developed within the scope of consumer protection and safety by Bureau Veritas, a global organization working in the fields of independent inspection, inspection, certification and risk prevention of French origin, the requirements for determining wheel or bearing performance in seats and chairs are explained and a test is carried out. method is defined. During this test, a maximum horizontal force of 91 kg is applied to move the seat or chairs on a flat vinyl surface for a maximum of 10 seconds, with a load of 2,3 kg applied to it. No measurement is made in the first 5 seconds of this test. The wheel is steered in the running direction throughout the test. Under these conditions, a malfunction or permanent deformation should not occur in the seat or chair wheels.
Rolling resistance is the effort required to move and maintain the seat or chair from a stationary state. A wheel that is hard enough not to deform under load performs perfectly on a flat hard surface. The closer to this result, the lower the rolling resistance. Obstacles on the ground adversely affect the performance of wheels and bearings, depending on their size.
In particular, office chairs or chairs are used frequently, and poor quality wheels are not likely to be efficient in distributing the weight evenly. Because these wheels and bearings are very likely to be subject to wear and tear. Soft rubber tires are generally ground-friendly. In addition, the tread width of the wheels is also important. However, regardless of the material used, it must have passed the tests described in this standard.
There are other standards for manufacturers, specifiers and users to evaluate safety, durability, structural adequacy and technical requirements for castors of seats and chairs. These standards define industry terms, specific tests, equipment and methods that may be used, test conditions, and minimum acceptance levels to be used in evaluating these products. These standards cover furniture chair wheels, industrial wheels, institutional and medical equipment wheels, and construction equipment and shopping cart wheels.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization provides test services to determine wheel or bearing performance in seats and chairs, within the scope of CPSD-HL-01058-MTHD standard, with its trained and expert staff and advanced technological equipment. also gives.
