COLLECTION OF SAMPLES FROM CONVEYOR BELT/ROPEWAYS. PIPELINES
a) Samples will be taken lot-wise as per Clause 5.
b) The sample shall be collected in increments of full cross section and thickness of the stream in one operation in a regular interval of time as mutually decided by both Seller and Purchaser and lot shall consist of samples so collected during a day i.e. 0:00 Hrs to 24:00 Hrs of the day.
c) Before collecting the increments, the speed of the conveyer belt/ropeways/pipelines and quantum of material passing a certain point in a given time shall be ascertained so that an appropriate spacing of time between increments may be arranged over the whole of the lot.
d) In case of supply through conveyor belt, if it is practicable to stop the belt periodically, increment may be collected from the whole cross section of the stream by sweeping the whole of the Coal lying between the sides of a suitable frame placed across the belt. The frame should be inserted in the Coal until it is in contact with the belt across its full width. If it is not possible, then sample is to be collected from falling stream of the belt at a suitable transfer point where coal is being released from one point to other.
