(5) For a person to use a false or incorrect weighmaster's certificate or a weighmaster's certificate not bearing the signature and license number of a licensed weighmaster and the license number of the vehicle and trailer or other means of permanent identification.

(6) For a weighmaster knowingly to permit a weighmaster's certificate to be issued or used which purports to bear the weighmaster's signature and which was not in fact signed by the weighmaster at a time of weighing or which expresses a gross, tare or net weight not ascertained by the weighmaster.

(7) For a person to deliver solid fuel without an official weighmaster's certificate.

(b) Prima facie evidence of short weight.--Whenever any commodity is sold and delivered to the purchaser named in the approved weighmaster's certificate and the seller or the seller's representative neglects, fails or refuses to deliver an approved weighmaster's certificate at the time of delivery or the net weight of the commodity is determined to be less than the net amount stated on the approved weighmaster's certificate or as otherwise represented to the purchaser, prima facie evidence of short weight shall exist, and the seller may be prosecuted under this section for short weight.
