What reference material is used to check measurement repeatability?
The company publishes no reference material and no repeatability check.
The polarity is a positive electric charge at rest, and it is measured as surface charge density, in nanocoulombs per square centimetre. The company publishes no measurement procedure, no instrument record and no uncertainty budget. A reference material and a repeatability check are part of a procedure, and the company publishes none. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
