Office Chair Static Pressure Armrest Comprehensive Testing Machine

Product Overview

The Office Chair Static Pressure Armrest Testing Machine is a specialized piece of equipment designed to test the static pressure performance of office chair armrests. It is primarily used by office chair manufacturers, furniture testing laboratories, and research institutions.

Product Application:

The Office Chair Static Pressure Armrest Testing Machine is a specialized device designed to evaluate the static pressure performance of office chair armrests. It is widely used by office chair manufacturers, furniture testing laboratories, and research institutions.

Product Features:

1. Static Pressure Strength Testing:

• Simulates the vertical pressure applied by the human body on the armrests of office chairs.
• Tests the strength and stability of the armrests under a certain static pressure to ensure they can withstand the weight of the user without damage or deformation during daily use.

2. Durability Testing:

• Repeatedly applies a set amount of pressure or conducts cyclic loading to simulate the stress experienced by armrests during long-term use.
• Evaluates the armrests' durability and resistance to fatigue, providing an estimate of their service life.

Compliance Standards:

• ANSI/BIFMA X5.1-2017 12 Arm Strength Test-Vertical-Static (Armrest Strength Test - Vertical - Static)
• ANSI/BIFMA X5.1-2017 13 Arm Strength Test-Horizontal-Static (Armrest Strength Test - Horizontal - Static)
• EN1335-2-2018, QB/T2280-2016, GB/T10357.3-2013

Technical Parameters

Control Method:

• PLC Touchscreen Control

Key Specifications:

1. Electric Cylinder:

   • Stroke: 600mm (adjustable based on sample specifications, finalized upon design drawing).
   • Capable of left-right movement.

2. Left and Right Pulleys:

   • Adjustable vertically to facilitate side strength testing of armrests in conjunction with the electric cylinder.
