##
**Assay Calculation**

While doing any assay calculation the result of assay
is expressed upto one decimal place more than the significant figures stated
and then the results are rounded up or down as follows.

If the last figure calculated is 5 to 9, the preceding
figure is increased by 1 & if it is 4 or less, the preceding figure is left
unchanged.

To find out significant figures for particular value
refer its specification limit, e.g. if limit is 99.00 to 102.00 then two
decimals from decimal point are significant. If limit is 98 to 101 then
significant figures are without decimal point.

Microbial Limit Test Report : The reading of count
expressed as a whole number. Pathogens reading is reported as Present / Absent
/ Positive / Negative.

Water analysis / Slit Air Sampling / Bacterial Count /
fungal Count / Settle Plate / Swab : Is expressed as a whole number.

Microbial Assay : Any microbial assay is expressed
either in terms of percentage / microgram / milligram.
