Abstract
Description
・ 熱電対試験(人がシートに10分間着席(コンディショニング/ウォームアップ)し、熱電対がシートの特定の場所に取り付けられ、温度上昇を記録する。次に、通気システムが10分間起動され、その間、人は着席しており、クールダウン温度が記録される。)
・ 空気流量試験(通気システムをオンにして、空気流量装置をシートの挿入エリアにしっかり押圧し、30秒後に読取りを行い、結果が平均化されてCFMに記録される。)
・ サーマルイメージング試験(この試験において、ヒートランプがシート挿入エリアに整列されて、華氏90度まで加熱することが可能にされ、画像がキャプチャされ、通気システムが5分間オンにされ、画像がキャプチャされる。)
・ 耐久性試験(80,000着席サイクル)
