The STEP Test is a simple method that can be used to quickly evaluate processing speed of automatic processors. It allows the identification of large deviations (>20%) in the processor-chemicals-film system. STEP means Sensitometric Test for the Evaluation of Processing. The performance of the processors taking part in the survey are calculated and compared to a standard processor where the film is processed under ideal conditions, according to manufacturer's recommendations. For each processor, in the dark room, a film is exposed to a sensitometer light, processed and the sensitometric curve is obtained. This survey was performed in 8 Moroccan hospitals in the cities of Casablanca and Rabat and included 11 processors. It was concluded that 50% of the processors present processing problems and are functioning under inadequate conditions since they present deviations larger than 20%.
STEP 测试是一种简单的方法，可用于快速评估自动处理器的处理速度。它可以识别处理器-化学物质-薄膜系统中的大偏差（>20%）。STEP 是用于评估处理的感光测试的缩写。根据制造商的建议，根据标准处理器对参与调查的处理器的性能进行计算和比较，在标准处理器下，薄膜在理想条件下进行处理。对于每个处理器，在暗室中，将胶片暴露于感光计光线下，进行处理并获得感光曲线。这项调查在摩洛哥的卡萨布兰卡和拉巴特这两个城市的 8 家医院进行，共涉及 11 个处理器。结果表明，有 50%的处理器存在处理问题，并且运行条件不足，因为它们的偏差大于 20%。
