(4) The person using the liquid fuel shall be entitled to witness the taking of a sample under paragraph (1)(b) and the determination of the temperature of such sample. (L.N. 262 of 1987) Cap 311B reg 7 Weighing of a sample Where the Authority or an authorized officer takes a sample under regulation 6(1)(a)(ii), he shall weigh the sample as soon as is reasonably practicable and the occupier of the premises upon which the sample is taken shall be entitled, upon request made to the Authority or authorized officer and at such place and time as the Authority may determine, to witness the weighing of the sample and be informed of the weight. (L.N. 262 of 1987) Cap 311B reg 8 Division of sample (1) The Authority or an authorized officer who takes a sample under regulation 6(1)(a)(ii) or (b) shall divide the sample into three equal parts, each part to be marked and sealed or fastened up in such manner as its nature will permit and if the sample taken is dust or grit or both, it shall not be divided until it has been weighed in accordance with regulation 7. (17 of 1983 s. 50; L.N. 262 of 1987) (2) When a sample is being divided under paragraph (1)- (a) the occupier of the premises upon which the sample is taken, if it is dust or grit or both; or (b) the person using the liquid fuel, if the sample is liquid fuel,shall be entitled to witness the division and thereafter, shall be permitted to select and retain one of the three parts of the sample. (3) Of the remaining two parts of the sample, the Authority or officer shall submit one to the Government Chemist for- (17 of 1983 s. 50) (a) size analysis, if it is a sample of dust or grit or both; or (b) determination of viscosity, if it is a sample of liquid fuel,and shall retain the other. Cap 311B reg 9 Size analysis and viscosity determination of sample When a sample is submitted to the Government Chemist under regulation 8(3), the Government Chemist shall- (a) if the sample is dust or grit or both- (i) analyse it for size by such method as he thinks fit; (ii) issue to the Authority or authorized officer who has submitted the sample, a certificate specifying the results of the size analysis of the sample, which certificate shall be in Form 1 in the Schedule to the Evidence Ordinance (Cap 8); and (iii) send, free of charge, to the occupier of the premises upon which the sample was taken, a copy of the certificate issued under sub-paragraph (ii); and(b) if the sample is liquid fuel- (i) determine its viscosity in accordance with any of the test procedures set out in the First Schedule; (ii) issue to the Authority or authorized officer who has submitted the sample, a certificate specifying the result of the viscosity determination, which certificate shall be in Form 1 in the Schedule to the Evidence Ordinance (Cap 8); and (iii) send, free of charge, to the person using the liquid fuel a copy of the certificate issued under sub-paragraph (ii). (17 of 1983 s. 50) Cap 311B reg 10 Emission of dust or grit If dust or grit is emitted from any furnace, oven, chimney, flue or industrial plant in excess of the limits set out in the Sixth Schedule, the occupier of the premises upon which the furnace, oven, chimney, flue or industrial plant is situated shall be guilty of an offence and shall be liable on conviction to a fine of $5000 and, in addition, to a fine of $50 for each day during which it is proved that the offence has continued. (L.N. 262 of 1987) Cap 311B Sched 1 TEST PROCEDURES FOR THE DETERMINATION OF VISCOSITY [regulations 2 & 9(b)] The viscosity of any liquid fuel shall be determined in accordance with- (a) in the case where it is to be expressed in centistokes, the test procedure laid down under IP 71/84 of the Institute of Petroleum; or (b) in the case where it is to be expressed in Saybolt Universal seconds, the test procedure laid down under ASTM D88-81 of the American Society for Testing and Materials; or (80 of 1997 s. 102) |
