定义
EN 17846:2023 — Chemical disinfectants and antiseptics — Quantitative test method for the evaluation of sporicidal activity against Clostridioides difficile on non-porous surfaces with mechanical action employing wipes in the medical area (4-field test) — Test method and requirements (phase 2, step 2)
中文可译为：化学消毒剂和防腐剂——采用湿巾在机械作用条件下，对医疗领域非多孔表面上的艰难梭菌芽孢杀灭活性进行评价的定量试验方法（四区域试验）——试验方法和要求（第 2 阶段，第 2 步）。
EN 17846 是专门用于评价消毒产品在实际擦拭条件下对 Clostridioides difficile（艰难梭菌）芽孢杀灭能力的 Phase 2, Step 2 测试标准。[1]该标准采用 4-field test。首先在指定测试区域接种并干燥 C. difficile 芽孢，然后使用浸有待测消毒产品的湿巾按照规定轨迹擦拭四个区域，同时评价产品对芽孢的杀灭能力以及擦拭过程中是否发生微生物传播。[1]该标准特别适用于包括预浸湿即用型消毒湿巾（pre-impregnated ready-to-use wipes）在内的实际表面消毒应用。[2]
