XRF技术进行RoHS筛选分析的判定标准

运用XRF技术进行筛选分析应遵循的判断标准可参考IEC62321提供的如下图1

Element Polymers Metals Composite Material
Cd BL ≤ (70-3σ) < X < (130+3σ) ≤ OL BL ≤ (70-3σ) < X < (130+3σ) ≤ OL LOD < X < (150+3σ) ≤ OL
Pb BL ≤ (700-3σ) < X < (1 300+3σ) ≤ OL BL ≤ (700-3σ) < X < (1 300+3σ) ≤ OL BL ≤ (500-3σ) < X < (1 500+3σ) ≤ OL
Hg BL ≤ (700-3σ) < X < (1 300+3σ) ≤ OL BL ≤ (700-3σ) < X < (1 300+3σ) ≤ OL BL ≤ (500-3σ) < X < (1 500+3σ) ≤ OL
Br BL ≤ (300-3σ) < X BL ≤ (250-3σ) < X
Cr BL ≤ (700-3σ) < X BL ≤ (700-3σ) < X BL ≤ (500-3σ) < X
