With the continuous development of sports infrastructure worldwide, the safety, structural stability, and reliability of sports facilities have become increasingly important to international buyers, engineering contractors, and venue operators. For retractable bleachers in particular, products must not only offer flexible operation and efficient space utilization but also demonstrate reliable load-bearing capacity and structural performance under different operating conditions.
The application of international standards and independent third-party testing has therefore become an important reference for evaluating the quality and performance of sports stadium facilities.
EN 13200-6:2020: An Important European Standard for Retractable Bleachers
EN 13200 is a European standard series covering spectator facilities in sports venues. It establishes technical requirements relating to the design, safety, and performance of facilities intended for spectators.
Within this series, EN 13200-6:2020 specifically addresses demountable and retractable spectator stands, providing technical guidance for their structural design, platform construction, and relevant safety performance requirements.
The standard provides an important technical reference for the design, manufacturing, and safety evaluation of retractable bleachers.
In particular, Clause 5.4.3 addresses imposed vertical loads, including distributed loading tests, which evaluate the structural deformation of a platform under uniformly distributed loads.
Clause 5.4.4 addresses isolated loads, or concentrated loading tests, which assess the platform's structural performance under localized loading conditions.
These two testing methods help evaluate the load-bearing performance, structural stiffness, and deformation recovery of retractable bleacher platforms under different loading conditions, providing valuable technical references for product design and quality control.
SMART GROUP Obtains a TÜV SÜD Third-Party Test Report
As a China-based supplier dedicated to providing one-stop comprehensive sports facility solutions for customers worldwide, SMART GROUP has always placed product safety and quality management at the core of its business operations.
On May 28, 2025, SMART GROUP's 360° Rotatable Manual Retractable Bleachers (Model: BLS-03) underwent independent third-party testing conducted by TÜV SÜD Certification and Testing (China) Co., Ltd., Guangzhou Branch, and received an official test report.
The test report number is 64.190.25.0267.01-00.
The testing was conducted according to the client's requirements, with reference to Clauses 5.4.3 and 5.4.4 of EN 13200-6:2020. The retractable bleacher platform was evaluated through distributed loading and concentrated loading tests.
The test results demonstrated the following:
Distributed Loading Test
A uniformly distributed load of 1,500 kg was applied to the bleacher platform, which had a total test area of 2.4 m².
Loading duration: 60 minutes
Maximum deflection under loading: 4 mm
Residual deflection after unloading: 0 mm
Concentrated Loading Test
A concentrated load of 150 kg was applied to a designated area measuring 0.2 m × 0.2 m on the bleacher platform.
Loading duration: 60 minutes
Maximum deflection under loading: 6 mm
Residual deflection after unloading: 0 mm
These test results demonstrate the structural performance and deformation recovery of the tested sample under the specified loading conditions, providing objective data for product structural evaluation and quality assessment.
