Huiya Access Floor Completes JIS A 1450 Testing Equipment and Achieves Japanese Standard Compliance, Empowering Expansion into Japan’s OA Floor Market

As Huiya’s raised access floor products continue to expand their influence in the Japanese market, quality requirements have grown increasingly demanding. Japan, being one of the world’s most mature markets for raised access floors (OAフロア / Free Access Floor), has established JIS A 1450 – the Test Methods for Raised Access Floor – issued by the Japanese Standards Association (JSA) and jointly promoted by the Japan Access Floor Association (JAFA / 日本フリーアクセスフロア工業会). It is globally recognized as one of the most systematic and rigorous testing systems in the industry.

To better serve Japanese customers, and to apply the same level of quality control to domestic projects, Changzhou Huiya Decoration Materials Co., Ltd. (czhuiya.com) has fully established eight categories of testing laboratory equipment in accordance with JIS A 1450:2021 and JAFA’s Performance Evaluation of Free Access Floor requirements. These cover every performance dimension of raised access floors — from dimensions to seismic resistance, from static to dynamic, and from structural to electrical safety.

This article details each test based on the core provisions of JIS A 1450 and the actual testing scenarios at Huiya’s laboratory.

I. Overview of JIS A 1450:2021

JIS A 1450, issued by the Japanese Standards Association (JSA), is the Test Methods for Free Access Floor and serves as the core reference for product performance evaluation by the Japan Access Floor Association (JAFA). The standard specifies test methods and evaluation criteria across eight major categories – dimensional measurement, static load, impact, rolling load, combustion, electrostatic propensity, leakage resistance, and seismic vibration – and represents an essential technical entry threshold for OA floor products in the Japanese market.

Prescribed accelerations:

  • 600 cm/s² (low-rise buildings, floors 1–4)
  • 1000 cm/s² (mid-rise buildings, floors 5–10)

The key evaluation focus is whether panels detach after the earthquake, plus damage, gaps, and horizontal displacement as evacuation safety indicators.

Criteria:

ItemCriterion
Amplitude amplification<2×, no obvious resonance
Resonant frequency>20 Hz (avoiding human-sensitive range)
Structural statusNo looseness, no abnormal noise, no shaking
PanelsNo detachment, no horizontal shift, no lifting

Huiya Equipment:
