盐酸氨气腐蚀试验箱

《家用和类似用途电器的安全 坐便器的特殊要求》(IEC 60335-2-84：2019第31.101条Toilet appliances shall have adequate resistance to cleaners and urine.);

GB/T 4706.53-20XX 31.101的试验要求：坐便器应对清洁剂和尿液有足够的防锈能力;

为通过《家用和类似用途电器的安全 坐便器的特殊要求》(IEC 60335-2-84: 2019)标准中的防锈测试，为确保实验的准确性和可靠性，我们需要在特定的环境条件下进行操作。首先，将盐酸的浓度设置为0.0005%，并确保环境温度维持在25℃。在这样的条件下，实验需持续运行96小时，随后排空盐酸并充入空气。接下来，将氨气的浓度设定为0.055%，同样保持环境温度为25℃，并继续实验96小时。这一严谨的操作流程旨在确保实验结果的稳定性和可靠性。
