Check product labels and instructions
Product identification: The pressure bar itself or its packaging is usually marked with load restrictions. Carefully check whether there is a printed or labeled maximum load bearing value on the surface of the pressure bar, generally in kilograms (kg). For example, a common pressure bar may be labeled “Max Load: 150kg”, which means that the maximum weight of the pressure bar is 150kg.
Product manual: The manual accompanying the product will provide more detailed technical parameters and instructions for use, which will necessarily include the load bearing limits of the pressure bar. When purchasing products with pressure rods such as office chairs, you should properly store and carefully read the instructions to understand the performance indicators of the pressure rods.
Refer to professional standards and certifications
Industry standards: The production of air pressure rods usually needs to comply with relevant industry standards, such as BIFMA (American Office Furniture Association standard), EN 1335 (European Office furniture Safety standard), etc. These standards have clear provisions on the bearing capacity and other performance indicators of different types and specifications of pressure rods. You can query the relevant standard documents to know the general bearing range of the corresponding pressure bar.
Certification mark: If the pressure bar has passed the certification of authoritative certification bodies such as SGS, TUV, etc., its certification report will have test data on the load-bearing capacity. The pressure bar with these certification marks indicates that it has been strictly tested in terms of load bearing, and the quality and safety are more guaranteed.
Observe the appearance and structure of the pressure bar
Size specifications: Generally speaking, the larger the diameter of the pipe and the thicker the wall of the pipe, the stronger its load-bearing capacity is. For example, a pressure bar with a diameter of 32 mm and a wall thickness of 1.5 mm can generally withstand greater weight than a bar with a diameter of 28 mm and a wall thickness of 1.2 mm.
Material and process: High quality material and superb manufacturing process can also improve the bearing capacity of the pressure bar. Such as the use of high-strength steel, welding technology excellent pressure rod, load-bearing capacity will be better than ordinary materials and technology products. It can observe whether the surface of the pressure bar is smooth and whether the welding place is uniform and firm to initially judge its technological level.
Take a practical test or consult a professional
Practical test: under the premise of ensuring safety, a simple practical test can be carried out to roughly judge the bearing capacity of the pressure rod. For example, a known weight is gradually placed on the seat or other equipment connected to the pressure rod to observe the deformation of the pressure rod and whether it can work normally. However, this method has certain risks, which may cause damage to the pressure rod, and non-professionals should be cautious.
Consult a professional: If you have questions about the bearing limit of the pressure bar, you can consult the manufacturer’s technicians, professionals in the furniture industry or relevant quality testing institutions. They have the professional knowledge and experience to give accurate load-bearing information according to the specific situation of the pressure bar.
