3、NSING GUN FOR DUAL-BARREL PAINT CARTRIDGES The General Services Administration has authorized the use of this commercial item description, for all federal agencies. 1. SCOPE. This Commercial Item Description (CID) covers manual dispensing guns for dual-barrel paint cartridges conforming to A-A-59815
4、. It does not define spray equipment and pneumatic wall dispensers. 2. CLASSIFICATION. Manual dispensing guns shall conform to the following types and sizes: 2.1 Type. Type A Fixed single-ratio applicator (either 1:1, 2:1 or 4:1) Type B Multi-ratio applicator (accommodates more than one mix ratio vi
5、a a single piece of equipment) 2.2 Size. The manual dispensing gun shall accommodate one or more of the dual-barrel cartridge sizes below, having a total system capacity of: Size 1 300-milliliter (mL) total capacity (150 mL by 150 mL) Size 2 375-mL total capacity (300 mL by 75 mL) Size 3 450-mL tota
6、l capacity (300 mL by 150 mL) Size 4 600-mL total capacity (300 mL by 300 mL) Size 5 750-mL total capacity (600 mL by 150 mL) Size 6 900-mL total capacity (600 mL by 300 mL) Size 7 1200-mL total capacity (600 mL by 600 mL) 3. SALIENT CHARACTERISTICS. 3.1 General design of manual dispensing gun. Manu
7、al dispensing guns shall eject paint from single- or multi-component dual-barrel paint cartridges fitted with static mixing tubes. Manual dispensing guns shall consist of a housing (or frame), triggered handle grip, plunger shafts and disks, retractable drive rod, drive rod release, and a cartridge
8、alignment device. The plunger and other moving parts shall be designed to prevent entrapment of the operators hands. Units shall be designed to incorporate ergonomic factors and to minimize the number of parts. The system shall accommodate both right-handed and left-handed users. Materials of constr
9、uction shall be selected to minimize the potential for reactivity with system components and paint products. 3.2 Housing. The housing shall be constructed of a steel, aluminum, or other rigid framework; be free of sharp burrs; and be sized to accommodate and permit easy insertion of dual-barrel cart
10、ridges. The housing shall be lightweight (not to exceed 5 pounds) for ease of handling. It shall assist in maintaining alignment of the dual-barrel cartridge with the plunger shaft. It shall secure the cartridge in operating position and prevent the cartridge from shifting during dispensing. As a mi
11、nimum, the housing shall have two openings through the back (handle grip end) to allow for passage of the plunger shafts. One additional opening shall be centrally located for transit of the retractable drive rod (see 3.5). It shall have an opening in the front to accommodate the cartridge nozzle an
12、d connection of the static mixer to the cartridge. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59838 2 3.3 Triggered handle grip. The triggered grip shall consist of two handles arranged as levers and provide a forward incremental movement al
13、ong the length of the drive rod when the trigger is squeezed. This, in turn, shall advance the plunger shafts and disks (see 3.4) to compress the piston end cap seals, thereby initiating release of paint components from the dual-barrel cartridge dispensing system. The handle grip shall have sufficie
14、nt strength to support the loaded gun assembly. All surfaces of the grip that come in contact with the operators hand shall be smooth or smoothly textured and free of sharp projections. The handle grip shall permit finger contact with the largest feasible area and be sized to accommodate 95 percent
15、of the anticipated user population when wearing light (solvent-resistant) gloves. Anthropometric (sizing) guidelines may be found in MIL-STD-1472. Integral handle stop points shall cradle the top side of the operators thumb and index finger, preventing hand slippage upward into the proximity of the
16、plunger shafts, drive rod or drive rod release mechanism. In the static open position, the handle grip diameter immediately below the upper stop points shall not exceed 76 mm (3 inches). The force required to activate the trigger shall be minimized and shall be less than strength criteria described
17、in MIL-STD-1472. 3.4 Plunger shafts and disks. The manual dispensing gun shall have a plunger shaft associated with each of two plunger disks. Plunger disks (sometimes called push disks) shall cover a minimum of 95 percent of the associated cartridge end cap seal surface that is perpendicular to the
18、 long axis of the cartridge. During dispensing, each plunger disk shall remain parallel to its respective cartridge end cap seal throughout the full stroke of the plunger shaft. 3.5 Retractable drive rod. The drive rod, a mechanism (e.g., a friction rod or ratchet rod) to advance and retract the plu
19、nger shafts, shall be centrally located between the said shafts. The action along the length of the drive rod that results from squeezing the triggered handle grip, shall advance the plunger shafts with their corresponding plunger disks in unison (i.e., with less than 1 percent mix ratio error) to p
20、rovide a mechanical advantage with a minimum thrust ratio of 18:1. The drive rod shall withstand the forces required to dispense a paint or coating with a viscosity of 155 Krebs Units (KU). The rearmost tips of the drive rod and plunger shafts shall be shielded by a plate, knob, or handle that facil
21、itates grasping. 3.6 Drive rod release. A release mechanism (e.g., a plate or lever) shall be present to disengage the compression that results from squeezing the triggered handle grip. The release shall be integral to the manual dispensing gun and easily accessible. The drive rod release shall allo
22、w for resetting of the plunger shafts to the starting uncompressed position when inserting new cartridges or to a partially extended position when inserting used cartridges. 3.7 Cartridge alignment device. Multi-ratio dispensing guns shall provide a means to accurately position and stabilize cartrid
23、ges in each of their respective mixing-ratio configurations during dispensing. To accomplish this, an alignment plate shall be located behind the plunger disks. The plate shall possess guide holes to align cartridges in the proper mixing ratio position for the given paint. 4. REGULATORY REQUIREMENTS
