In the salt spray test, the test specimens are exposed to a salted atmosphere at an elevated temperature, thus simulating exposure to oxidizing corrosive substances with a time-lapse effect. In addition, acetic acid (AASS) or copper chloride (CASS) can be used as further spray additives. Salt spray tests are also often combined with other corrosion test methods to perform so-called corrosion cycling tests. Among the features of the RSI corrosion test chests are – Structure in accordance with DIN EN ISO 9227, DIN EN 60068-2-11, ASTM B117. – Test chamber material: Polypropylene or special stainless steel materials – Ergonomic touch panel control – Integrated measurement data acquisition – Dosing of the salt spray solution via regulated diaphragm pump – Brine storage tank with free access for the operating personnel – Wide range of options and customer-specific requirements – Suitable for Corrosion tests according to ISO 6270-2, ISO 9227, ASTM B 177, VDA 621-415, PV 1208, PV 1209, PV 1210, ISO 11997, LV 124, Volvo 423-0014, Volvo STD 1027, SAE J 2334, DIN 55635, VDA 233-102, PPV 4017, Renault ECC 1, GMW 14872, GMW 3172 und more
1 适用范围PV1210交变盐雾气候冷凝试验箱 本检验规范用于具有不同防腐涂层的油漆的车身、车身薄板、结构组件和结构件的样品检验及批量检验中的腐蚀检测。 它用来检验和评价静态载荷下的防腐特性和防腐方法。 2 名称PV1210交变盐雾气候冷凝试验箱 根据PV 1210确定的耐腐蚀性 3 检验方法 3.1 原理 该检验是不同气候和/或腐蚀负荷的循环变化的组合。 一个检验循环包括 — 4 小时的盐雾检验,按 DIN 50 021-SS, — 4 小时标准气候 DIN 50 014-23/50-2(包括冷却阶段)下的存放, — 16 小时的湿热存放,气候按 DIN 50 017-KK(40 ± 3)℃; )100%空气湿度。 5个循环后是 2 天在标准气候 DIN 50 014-23/50-2 下的静止状态。 用这种试验方法通过盐、湿度和温度来评价静态负荷下的腐蚀特性。 在这种特定的腐蚀条件下,可以对不同的防腐涂层进行对比评价。 腐蚀机理的关联作用在行驶过程中不是必然能出现的,因为在汽车上出现的损害形成及腐蚀过程是更为复杂的形式,并不能通过变化的腐蚀载荷来地把握和表现出来。 短时间地中断检验以检验和/或取出试样是允许的。更改检验程序来中断检验是不允许的。
