1. (1) Scope. 202 CMR 2.11 covers grades of heating oil intended for use in various types of fuel-burning equipment under various operating conditions.

2. (2) General Requirements.

   1. (a) The grades of heating oil specified in 202 CMR 2.11 shall be homogeneous hydrocarbon oils, free from inorganic acid, and free from excessive amounts of solid or fibrous foreign matter likely to make frequent cleaning of strainers necessary.
   2. (b) Grades containing residual oil shall remain homogeneous in normal storage and not separate into light and heavy components.

3. (3) Detailed Requirements.

   1. (a) The various grades of heating oil shall conform to the requirements shown in 202 CMR 2.11: Table 1.
   2. (b) The statutory regulations of health or environmental agencies willsupersede those outlined in 202 CMR 2.11: Table 1 when they are more stringent than as outlined. Higher sulfur may be permitted in accordance with Massachusetts Department of Environmental Protection regulations at 310 CMR 7.21 and 7.22 which provide for exceptions where approved equipment results in lowering the air polluting effect.

4. (4) Methods of Test.

   1. (a) The detailed requirements enumerated in the minimum standards shall be determined in accordance with the following American Society for Testing and Materials Methods:

      1. 1. Flash Point: Pensky-Martens Closed Tester (ASTM D-93)
      2. 2. Pour Point: ASTM D-97

      3. 3. Water and Sediment:

         Grades 1, 2, 4 and 5: ASTM D-1796 Grade 6: ASTM D-95 and ASTM D-473

      4. 4. Ash: ASTM D-482
      5. 5. Distillation: ASTM D-86

      6. 6. Viscosity:

         Grades 1 and 2 (Kinematic): ASTM D-445 Grades 4, 5 and 6 (Saybolt): ASTM D-88

      7. 7. Gravity: Hydrometer Method - ASTM D-287
      8. 8. Corrosion: Copper Strip, ASTM D-l30, 3 hours @ l22F.

      9. 9. Sulfur: Any grade may be determined by the following:

         Bomb Method - ASTM D-129 Quartz-Tube Method - ASTM D-1551 High Temperature Method - ASTM D-1552 X-Ray Spectrograph Method - ASTM D-2622

         In addition, sulfur in Grade 1 may be determined by the Lamp Method - ASTM D-1266

   2. (b) Every manufacturer or distributor of heating oils shall submit samples of said products when requested by the Director of Standards.

   3. (c) The Director of Standards, or his authorized agent, may enter each place where heating oils are stored or kept for sale and any vehicle used for its conveyance and may inspect said oil or take therefrom samples for analysis. The Director shall cause each sample taken to be analyzed or otherwise satisfactorily tested and shall record and preserve as evidence the results thereof.
