Aky je rozdiel medzi necertifikovanym LM a certifikovanym VST? Okrem ceny.
Este doplnim, VST misky su len certifikovane, LM Strada (certifikovane) su rovnake, ako VST. Na miskach je QR kod a sucastou balenia je aj protokol o merani. Necertifikovane by mali byt oznacene len LM (?) a bez QR kodu a protokolu.
Zo stranky VST o kontrolnom procese (certifikacii):
- 100% of holes are measured on every filter for min/max range limits on area and diameter to a precision of +/- 20 µm (individual QC report provided with every filter)
- All holes are measured for circularity, placement, square area and blocked holes
- Hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck.
