No. of Sampling Point= 27 [ Area of Room]
/1000
there will be 27 in place of 257 and this formula is applicable for only room area greater than1000.
pls refer updated ISO guideline 2015 for more detail.
Mean we have to folow chart there is no equation for area less than 1000?
Yes you should follow this.
