How to ensure brake casters meet safety standards?

Ensuring brake casters meet safety standards requires a comprehensive approach covering the entire design, production, testing, and certification process. The following measures should be implemented in conjunction with international and domestic standards (such as EN 12530, ISO 22881, and GB/T 14687-2011):

1. Clarify design specifications based on standards
Parameter benchmarking: Before design, determine applicable standards based on the target application (such as industrial or medical), and clearly define key parameters for brake casters, such as the maximum load, braking strength, and material weather resistance. For example, according to EN 12530, the brake mechanism must prevent wheel rotation or slippage at a horizontal pull of 15% of the load.
Structural compliance: The design of the brake mechanism (such as full brake or side brake) must meet the standard's requirements for braking stability. For example, full brakes must simultaneously lock wheel rotation and the steering bracket to avoid the risk of "brake failure." The brake pedal's size and pedal force must be ergonomically optimized to prevent misoperation.

2. Strict Control of Materials and Production Processes
Material Compliance: Brake components (such as brake pads, springs, and metal brackets) must be made of durable materials that meet standards. For example, brake pads must have a high coefficient of friction and be wear-resistant (e.g., rubber or polyurethane). Metal brackets must undergo anti-corrosion treatment (e.g., galvanizing or spray coating) to meet corrosion resistance requirements.
Process Specifications: Standardized processes must be implemented during production to control key steps, such as calibrating the spring rate of brake springs and inspecting the fit accuracy of brake pads to the wheel, to prevent unstable braking performance due to process errors.

3. Comprehensive Testing to Verify Performance
Braking Performance Testing: Braking performance is tested under different loads (no load, rated load, and 125% overload) simulating actual use scenarios according to standards. This ensures that the wheel does not slip when the specified horizontal force is applied and that the brake does not loosen after locking.
Durability Testing: Cycling the brake pedal (e.g., the thousands of cycles required by EN 12530) is used to verify the fatigue resistance of the brake mechanism and prevent problems such as spring failure and excessive brake pad wear after long-term use. Environmental Adaptability Testing: Braking performance is tested under conditions such as high and low temperatures, humidity, and oil pollution to ensure that the materials and structure can maintain stable braking in harsh environments (e.g., rubber brake pads do not harden or soften at temperatures between -20°C and 60°C).

4. Compliance Certification and Document Traceability
Third-Party Certification: Apply for compliance certification specific to the target market. For example, exports to Europe require EN 12530 testing and CE certification, while domestic sales require compliance with GB/T 14687-2011 and inspection by a quality inspection agency.
Document Retention: Retain documents such as design drawings, material quality inspection reports, and test data to ensure traceability of each batch of products, facilitating verification by regulatory authorities or customer factory inspections to demonstrate compliance.

5. Supply Chain and After-Sales Control
Supplier Auditing: Qualifications of suppliers of brake components (such as bearings and brake pads) are reviewed, ensuring that their materials and performance meet relevant standards to prevent substandard products from failing to meet overall standards due to substandard components. After-sales feedback optimization: We collect user feedback on brake failures (such as brake failure and unusual noise) during use and continuously improve design and process in accordance with standard requirements to ensure product safety compliance throughout its lifecycle.
Through this comprehensive process control, we ensure that brake casters meet international and domestic standards for braking performance, durability, and safety, from source to end-user, reducing user risks.
