OTHER FOODGRAINS:
Any food grains other than the grain concerned.

VARIETAL ADMIXTURE:
The presence of variety of the same grain other than the variety under consideration shall constitute the varietal admixture.

IMMATURE:
Kernals or pieces of grain kernals that are not fully devoloped.

BROKENS:
Pieces of kernals that are less than three-fourths of the size of the full kernals.In  case of dals,pieces that are less than the size of three-fourths of the split pulse shall be considered as brokens.
  A) BIG BROKENS:
      Those pieces of rice kernals hich are equal to or smaller than three-fourths but bigger than one half of the average length of the unbroken kernal.
  B) MEDIUM BROKENS:
       Those pieces of rice kernals  which are equal to or smaller than one-half but bigger than one-quarter the average length of the unbroken kernal.
  C) SMALL BROKENS:
       Those pieces of rice kernals which donot exceed one-fourth of the average length of unbroken kernal,retained on 1.10mm IS sieve.

DAMAGED:
Kernals or pieces of kernals that are sprouted or internally damaged as a result of heat,microbes,moisture or weather.

SLIGHTLY DAMAGED OR TOUCHED:
Kernals or pieces of kernals that are damaged or discolored superficially so as not to affect the quality of the material.

INSECT DAMAGED:

FRAGMENTS:
Pieces of kernals that are one-eighth of the size of the full kernals.

DE HUSKED GRAINS:
Kernals,whole or broken which have more than one-fourth of the surface area of the kernal covered ith bran.

FRAGMENTS IN SPLIT PULSES:
Pieces of kernals taht are one-fourth or less than the full size of the split pulse.

MOISTURE:
The loss in mass caused as a result of heating for to hours at 130 degree centigrade to 133 degree centigrade under specified conditions and expressed as percentage.

  1. I would suggest a correction in the definition of FRAGMENTS:
    "pieces of kernels that are less than one-eighth of the size of the full kernels"
