Which standard corresponds to the differentiation and integration in the oil particle counter detection report

The differentiation and integration in the oil particle counter detection report correspond to different standards. Specifically, as follows:

1. Differential standard: Differential standard refers to the classification of particle pollution levels based on the NAS1638 standard. The NAS1638 standard divides the maximum allowable particle count in oil within the size range of 5-15, 15-25, 25-50, 50-100, and>100um into 14 pollution levels. The measured particles in each size range often have different levels, and generally one level is taken as the oil pollution level.

2. Integral standard: The integral standard refers to the classification of particle concentration levels according to the ISO4406 standard. The ISO4406 standard is divided into 26 levels based on the size of particle concentration. The country has made modifications and improvements to the ISO4406 standard. The revised ISO4406:1999 stipulates that for pollution levels counted using automatic particle counters, three particle concentration levels of>4um,>6um, and>14um are used to represent.

In summary, the differentiation and integration in the oil particle counter detection report correspond to different aspects of the NAS1638 and ISO4406 standards, respectively. The differentiation corresponds to the pollution level, while the integration corresponds to the particle concentration level.

The detection results of PLD-0201, PMT-2, and PLD-0203 oil particle counters can be output according to standards such as NAS 1638, ISO 4406, SAE 4059E, SAE 4059F, GJB 420A, and GJB 420B.

The puluody oil particle counter adopts puluody technology - "light resistance measurement of particles", and adopts the classic methods of NAS1638 and ISO4406 in the oil industry. It can also be equipped with multiple standards according to user requirements.
