Applicant's summary and conclusion

Conclusions:
The particle size distribution (granulometry) of 3-amino-2hydroxy-5-nitrobenzene sulphonic acid by the sieve analysis method was found to be in the range of 53 micrometer to 500 micrometer. Majority of the particles were found to be in the size more than 150 (35.65%) - 75 (28.58%) micrometer in size.
