All sticks for scaling wood shall conform to the following requirements: (a) The zero end of each stick shall have metal securely attached to it.(b) Markings indicating graduations and numbers shall be permanent and easily read.(c) The finish shall be smooth and painted with a durable clear coating.(d) The allowable error in graduations shall be determined according to the following table: | Nominal Interval from Zero (Feet) | Tolerance in Excess or Deficiency No Greater than (Inches) |
| 3 or less | 0.1 |
| 4 | 0.13 |
| 5 | 0.16 |
| 6 | 0.19 |
| 7 | 0.21 |

2. Flexible measuring tape Flexible measuring tapes shall conform to the following requirements: (a) Tapes shall be made of steel, fiberglass, or other material equal in durability to steel or fiberglass.(b) Markings indicating graduations and numbers shall be permanent and easily read.(c) The tolerance in excess and deficiency for graduations on flexible measuring tapes shall be for 5 feet or less, 0.1 inches, and for each additional 5 feet, 0.1 inches. NOTE: Construction and accuracy specifications. Construction and accuracy specifications for all measuring instruments are available upon written request to the State Sealer.
B.Length measurements. Linear, lineal or length measurements consist of determining the length of a line from one point to another. Linear refers to the length of the piece of wood along the vertical growing axis of the tree. Lineal refers to the measurement of the diameter of a cross section of the tree which is assumed to be circular in shape.C.General rule for rounding off. Where not otherwise provided in these rules, decimals may De rounded off to the nearest whole interval. When the measurement is on the midpoint between two intervals, round down.01-001 C.M.R. ch. 382, § 1
