3 Terms and definitions
The following terms and definitions are applicable to this document.
3.1 Nominal capacity
The capacity of dispenser indicated by the manufacturer.
Note: such as 20 mL, 30 mL, 50 mL.
3.2 Graduated capacity
The volume of water ?€? at a temperature of 18 ??C ~ 28 ??C ?€? discharged from the body, when the fiducial line of the piston moves axially for a given scale interval. 3.3 Total graduated capacity
The capacity of the body from the zero mark to the furthest mark.
Note: The total graduated capacity can be greater than or equal to the nominal capacity. 3.4 Maximum usable capacity
The capacity of the body when the plunger stopper is drawn to its farthest functional position.
3.5 Fiducial line
The ring line at the end of the plunger stopper, which is in contact with and vertical to the barrel of the body, and is aligned with the zero-graduation line on the barrel of the body when the piston is fully pushed to the bottom of the casing.
3.6 Dispensing needle
The combination of needle tube, needle file and sheath, which can be divided into two types ?€? side-hole and bevel ?€? according to the needle tip type.
3.7 Side-hole needle
A needle tube with a closed tip and an opening on one or both sides adjacent to the tip. 3.8 Bevel needle
A needle tube with a bevel opening on one end and an included angle with its axis. 3.9 Plunger stopper
Sealing assembly between the barrel and the plunger (3.10).
c) Express the division capacity line of the additional scale by a shorter scale line; d) Express vertical lines of the additional scale lengths by dotted lines. 6.3.1.3 The graduated capacity line shall be uniform in thickness and shall be located on a plane at right angles to the axis of the barrel.
6.3.1.4 The graduated capacity lines shall be evenly spaced along the longitudinal axis of the barrel between the zero line and the total graduated capacity line. 6.3.1.5 When the dispenser is maintained in a vertical position, the ends of all graduated capacity lines of equal length shall be vertically aligned with each other. 6.3.1.6 The length of the secondary graduated capacity line is about 1/2 of the length of the main graduated capacity line.
6.3.2 Numbers on the scale
The graduated line shall be marked according to the maximum incremental value specified in Table 1. If the nominal capacity line is inconsistent with the total graduated capacity line, it shall be marked with numbers. Hold the dispenser vertically, with the cone pointing up; the number shall be vertically located on the ruler, and shall be in the center half of the extension line of the corresponding capacity scale. The numbers shall be close to, but not touching the ends of the corresponding graduated line. 6.3.3 Total length of the scale of the nominal capacity line
The total length of the scale shall meet the requirements in Table 1.
6.3.4 Scale position
When the plunger stopper is fully pushed to the bottom of the barrel, the zero- graduation line of the scale shall be aligned with the fiducial line on the plunger stopper, and the error shall meet the capacity tolerance requirements in Table 1. 6.3.5 Printing of scales
6.3.5.1 The scale of the partial-head dispenser shall be printed on the opposite side of the cone.
6.3.5.2 The scale of the center-head dispenser shall be printed on either side of the short axis of the barrel flanges.
6.3.5.3 The graduated capacity line and digital printing shall be complete, with clear handwriting, distinct lines and uniform thickness.
