3 Code definition
3.1 General
The purpose of this code is to simplify the reporting of particle count data by converting the numbers of particles into broad classes or codes, where an increase in one code is generally a doubling of the contamination level.
The original code, in accordance with the first edition of this document, stated the reporting at two sizes 5 pm and 15 pm. The sizes in this document account for the use of a different calibration standard for optical automatic l)articlc counters (APCs). The reported sizes are 4 pni(c), 6 pm(c) and 14 iim(c), the last two of these being equivalent to the 5 pm and 15 pm particle sizes obtained using the ISO 4402:199111 met hod of calibrating APCs. Throughout this document the use of pm(c) meaiis that particle size measurements are carried out using an automatic particle counter that has been calibrated In accordance with ISO 11171.
Measurement of particles using an optical microscope as specified in ISO 4407 establishes the size of a particle as being equal to its longest dimension, whereas an automatic particle counter derives the size of an equivalent particle from its cross—sectional area, a value different in most cases from that determined using a microscope. •rhe particle sizes to be reported for measurement by microscope 5 pm and 15 pm are unchanged from those specified in the first edition of this document.ISO 4406 pdf download.
