Standard intervals: 5–10 working days for a single LVD or EMC item; 7–12 working days for the combined LVD+EMC; 3–7 working days for RoHS; 10–20 working days for the full wireless RED package; 10–25 working days for machinery MD; 15–40 working days for pressure equipment PED; 20–60 working days for construction products CPR. Projects requiring NB involvement also require an additional 2–4 weeks for review scheduling.
The above does not include product rectification time. If the first round of testing fails, rectification + retesting usually adds another 1–3 weeks. During peak seasons (March–May and September–November each year), laboratory scheduling is tight, and the lead time may increase by 30%.
