EN 957-4:2006/FprA1

Overview

EN 957-4:2006/FprA1 is a European standard developed by CEN under Technical Committee CEN/TC 136. This standard focuses on stationary training equipment, specifically targeting strength training benches and free-standing barbell racks. It supplements the general safety requirements outlined in EN 957-1 by specifying additional safety requirements and test methods designed to ensure the structural integrity and user safety of these benches when used for strength training exercises. The standard applies to stationary benches classified as types S, H, and I.

Key Topics

• Safety Requirements
  EN 957-4:2006/FprA1 sets forth specific safety criteria for strength training benches and barbell supports to prevent breakage or failure during use. For instance, the rear part of the barbell support must endure non-symmetric impacts without degradation in performance or breakage.

• Barbell Support Strength Testing
  The standard introduces a detailed test method using a pendulum device to simulate impacts on the rear part of each barbell support individually. Impact tests must be repeated multiple times (10 times per support) with loading conditions reflecting the highest user weight or manufacturer’s specified loads.

• Load Specifications
  Testing loads are defined based on the classification of the bench (S, H, or I), with minimum weight requirements such as 40 kg for Class H and 50 kg for Classes S and I. Testing ensures equipment can sustain real-world stresses in strength training environments.

Applications

EN 957-4:2006/FprA1 is vital for manufacturers, testing laboratories, and safety regulators involved with indoor sports equipment, specifically for strength training benches used in gyms, fitness centers, and rehabilitation facilities.

• Manufacturers can use this standard to design and test strength training benches that meet European safety expectations, thereby assuring customers of product reliability and safety.
• Certification bodies rely on the standard to verify compliance with stringent safety criteria before products enter the market.
• Gym operators and fitness facilities benefit indirectly by choosing equipment certified under EN 957-4, ensuring user safety and reducing liability risks.

Related Standards

• EN 957-1: General Safety Requirements
  EN 957-4 should be read in conjunction with EN 957-1, which lays the foundation for safety requirements applicable to all stationary training equipment.

• Other Parts of EN 957 Series
  The EN 957 series covers a variety of stationary training equipment types. Depending on the equipment being certified or used, other parts such as those covering strength machines or cardiovascular trainers may also apply.

• International Equipment Standards
  While EN 957-4 focuses on European market requirements, equivalent international standards may exist, and manufacturers targeting a global market should align with both EN 957-4 and relevant international standards.
