BS EN 1335 Office Chairs Strength Durability and Safety Testing
The British Standard (BS) and European Norm (EN) standard BS EN 1335 is a crucial document for ensuring the quality, safety, strength, and durability of office chairs. This service focuses on testing according to this standard, which is widely recognized in Europe and beyond as a benchmark for high-quality office furniture.
Office chairs are subjected to various stresses during use, including but not limited to static loads from users, dynamic movements caused by chair adjustments, and environmental factors like temperature changes. The BS EN 1335 testing protocol aims to simulate these real-world conditions to assess the structural integrity of the chair. This is essential for quality managers, compliance officers, R&D engineers, and procurement teams who need to ensure that their products meet stringent safety and performance requirements.
The standard covers a range of tests including static load tests, durability testing (under simulated use), stability checks, and impact resistance evaluations. Static load tests are performed at different weight increments to check the chair’s ability to support users without deformation or failure. Durability testing simulates an average user’s daily activities over extended periods, typically 10,000 cycles for each function.
Stability checks ensure that the chair remains stable under various conditions such as when a person sits in it suddenly or adjusts its position rapidly. Impact resistance evaluations determine how well the chair withstands accidental impacts from users. These tests are critical to maintaining safety standards and preventing accidents.
The results of these tests are vital for manufacturers to identify potential weaknesses in their designs early on, allowing them to make necessary adjustments before product launches. Compliance with BS EN 1335 also enhances brand reputation by demonstrating commitment to quality and safety. For procurement teams, this service ensures that only high-quality chairs made to meet the required standards are selected.
Understanding the test parameters is key to successful testing outcomes. Static load tests involve placing a specified weight at different points on the chair while monitoring deformation and stability. Durability testing uses realistic user movements recorded in cycles of use, simulating typical office environments. Stability checks include scenarios where unexpected forces might be applied suddenly or during adjustment.
Impact resistance evaluations assess how well the chair can absorb and distribute impact forces without compromising safety. The instrumentation used for these tests includes load cells to measure applied loads accurately, force sensors embedded in the seat and backrest to monitor pressure distribution, and video cameras to record movements throughout testing cycles. Reporting is comprehensive, detailing every aspect of each test run, including visual documentation and detailed metrics.
The importance of this service cannot be overstated for any organization involved in manufacturing or purchasing office chairs. It ensures not only compliance with international standards but also the creation of safe, durable furniture that meets user expectations.
Scope and Methodology
| Test Type | Description | Apparatus Used | Acceptance Criteria |
|---|---|---|---|
| Static Load Test | Subject the chair to specified weights at different points. | Load cells, force sensors. | No deformation or failure under load. |
| Durability Testing | Simulate daily use over 10,000 cycles for each function. | User movement simulators, video cameras. | No functional failures during specified use cycles. |
| Stability Check | Evaluate chair stability under various conditions including sudden load changes and rapid adjustments. | Force sensors in the seat and backrest. | The chair remains stable without tipping over or collapsing. |
| Impact Resistance Evaluation | Determine how well the chair withstands accidental impacts from users. | Impact force measurement equipment, video cameras. | No structural damage or compromise in safety features after impact. |
The tests are conducted using state-of-the-art instrumentation and equipment designed to accurately measure the performance of office chairs under various stress conditions. The acceptance criteria ensure that all chairs pass stringent requirements, guaranteeing they meet both user expectations and regulatory standards.
