P. 5/11 8. 耐候性能 Environmental Characteristics 試験項目 Item 試 験 条 件 Test Condition 試験後の規格 Specification 8-1 高温放置 Dry Heat Test (Storage) 温度+85±2℃に 240 時間保持し、常温に取 出し 4 時間放置後測定します。 Components shall be left in a chamber (Temperature: +85 2C) for 240 hours, then measured after leaving in natural condition for 4 hours. 第 1 表を満足しま す。 The measured value shall meet Table 1. 8-2 低温放置 Cold Test (Storage) 温度-40±2℃に 240 時間保持し、常温に取出 し 4 時間放置後測定します。 Components shall be left in a chamber (Temperature: -40 2C) for 240 hours, then measured after leaving in natural condition for 4 hours. 8-3 耐湿性 Humidity 温度+40±2℃,湿度 90~95%R.H.の恒温恒 湿槽中に 240 時間保持し、常温に取り出し 4 時間放置後測定します。 Components shall be left in a chamber (90 to 95% R.H. at +40 2C) for 240 hours, then measured after leaving in natural condition for 4 hours. 8-4 温度サイクル Temperature Cycle 温度-40±2℃の恒温槽中に 30 分間保持後室 温(+20℃)に 15 分間保持し、更に温度+85±2℃ の恒温槽中に 30 分保持後、室温(+20℃)に 15 分間保持します。これを 1 サイクルとして 5 サ イクル行い、常温に 4 時間放置後測定します。 After being placed in a chamber at -40±2C for 30 minutes, components shall be placed at room temperature (+20C). After 15 minutes at this temperature, components shall be placed in a chamber at +85±2C. After 30 minutes at this temperature, components shall be returned to room temperature (+20C) for 15 minutes. After 5 above cycles, components shall be measured after being placed in natural condition for 4 hours. 表 1 Table 1. 項 目 Item 試験後の変化量 Specification after test 音圧レベル Sound Pressure Level 初期値±10dB Initial Value±10dB |
