ANSI/KCMA A161.1 Standard
In accordance with the procedures set by ANSI for the revision of standards, KCMA has initiated the canvass balloting process for the KCMA A161.1 standard. KCMA has also sent a request to ANSI to publish a notice in Standards Action that the KCMA A161.1 standard is under review and KCMA is soliciting public comment on the draft standard. This public comment period will be open for 45 days from the notification date.
Any comments received either by the canvass participants or through public comment on the draft standard will be considered by the canvass participants and, if a change is made to the draft based on comment(s) submitted, the canvass participants will vote on the revised draft. KCMA anticipates publishing the latest copy of the KCMA A161.1 standard during the first quarter of 2022.

To begin the process for certification under the ANSI/KCMA A161.1 Standard, American cabinet manufacturers must make sure the cabinet line(s) they are looking to certify meets these 14 requirements. After these are met, 8 categories of tests are conducted. Companies do not have to be a member of KCMA to participate.
All cabinets must be fully enclosed with backs, bottoms, sides and tops on wall cabinets; and backs, bottoms and sides on base cabinets, with certain specified exceptions on kitchen sink fronts, sink bases, oven cabinets and refrigerator cabinets.
All cabinets designed to rest on the floor must be provided with a toe space at least two inches deep and three inches high.
All utility cabinets must meet the same construction requirements as base and wall cabinets.
Doors and drawers must be properly aligned, have means of closure and close without excessive binding or looseness.
All materials must ensure rigidity in compliance with performance standards.
Face frames, when used, must provide rigid construction.
For frameless cabinets, the ends, tops/bottoms and back shall be of thickness necessary to provide rigid construction.
Corner or lineal bracing must be provided at points where necessary to ensure rigidity and proper joining of various components.
All wood parts must be dried to a moisture content of 10 percent or less at time of fabrication.
All materials used in cabinets must be suitable for use in the kitchen and bath environment where they may be exposed to grease, solvents, water, detergent, steam and other substances usually found in these rooms.
All exterior exposed surfaces and edges except the edges of end panels and the edges of back panels, shall be free of saw marks and other imperfections and shall be filled and sanded, edge-banded or otherwise finished to ensure compliance with the performance standards.
All exterior exposed parts of cabinets must have nails and staples set and holes filled.
All exposed construction joints must be fitted in a workman-like manner consistent with specifications.
Exposed cabinet hardware must comply with Builders Hardware Manufacturing Association finishing standards.
CATEGORIES FOR TESTING
- Structural Tests
- Drawer Tests
- Door Operation Tests
- Finish Tests
5 Structural Tests
These tests are meant to verify the structural integrity and strength of cabinets
- All shelves and bottoms are loaded at 15 pounds per square foot, and loading is maintained for seven days to ensure that there is no excessive deflection and no visible sing of join separation or failure of any part of the cabinets or the mounting system.
- Mounted wall cabinets are gradually loaded to 600 pounds without any visible sign of failure in the cabinet or the mounting system.
- To test the strength of base-front joints, a load of 250 pounds is applied against the inside of cabinet-front stiles for cabinet with drawer rails, or 200 pounds is applied for cabinets without drawer rails, to ensure reliable front joints that will not open during stress in service or during installation.
- To test the ability of shelves, bottoms and drawer bottoms to withstand the dropping of cans and other items, a three-pound steel ball is dropped from six inches above the surface. After the test the drawer must not be damaged and must operate as before the test with no visible sign of joint separation or failure of any part of the cabinet or mounting system.
- To test the ability of cabinet doors and connections to withstand impacts such as children falling against a cabinet, a 10-pound sandbag is used to strike the center of a closed cabinet door and repeated with the door opened to a 45-degree angle. The door must operate as before the test and show no damage or sign of separation or failure in the system.
2 Drawer Tests
- To test the ability of drawers and drawer mechanisms to operate with loading during normal use, drawers are loaded at 15 pounds per square foot and operated through 25,000 cycles. The drawers must then remain operable with no failure in any part of the drawer assembly or operating system, and drawer bottoms must not be deflected to interfere with drawer operation.
- To test the ability of the drawer-front assembly to withstand the impact of closing the drawer under normal use, a three-pound weight is dropped 8 inches against the drawer assembly. After 10 drops, there must be no evidence of looseness or structural damage to the drawer-front assembly that impairs operation.
2 Door Operation Tests
- To test the ability of doors, hinges and means of attachment to withstand loading, 65 pounds of weight is applied on the door. The weighted door is slowly operated for 10 cycles from 90 degrees open to 20 degrees open and returned to the 90-degree position. The door must remain weighted for 10 minutes, after which the door and hinges must show no visible signs of damage, and connections between cabinet-and-hinge and door-and-hinge must show no sign of looseness.
- To test the ability of doors, door-holding devices, hinges and attachment devices to operate under the stress of normal use, doors are opened and closed through a full 90-degree swing for 25,000 cycles. At the test's conclusion, the door must be operable, the door-holding device must hold the door in the closed position, hinges must show no visible signs of damage, connections between cabinet-and-hinge and door-and-hinge must show no sign of looseness, and other specifications must be met.
4 Finish Tests
These tests create, in accelerated form, the cumulative effects of years of normal kitchen conditions of pre-finished cabinets. Cabinet finishes are inspected to ensure that stringent standards of appearance are also met.
- To test the ability of the finish to withstand high heat, a cabinet door is placed in a hotbox at 120 degrees Fahrenheit and 70 percent relative humidity for 24 hours. After this test the finish must show no appreciable discoloration and no evidence of blistering, checks or other film failures.
- To test the ability of the finish to withstand hot and cold cycles for prolonged periods, a cabinet door is placed in a hotbox at 120 degrees Fahrenheit and 70 percent relative humidity for one hour, removed and allowed to return to room temperature and humidity conditions, and then placed in a coldbox for one hour at -5 degrees Fahrenheit. The cycle is repeated five times. The finish must then show no appreciable discoloration and no evidence of blistering, cold checking or other film failure.
- To test the ability of the finish to withstand substances typically found in the kitchen and bath, exterior exposed surfaces of doors, front frames, drawer fronts and end panels are subjected to vinegar, lemon, orange and grape juices, tomato ketchup, coffee, olive oil and 100-proof alcohol for 24 hours and to mustard for one hour. After this test, the finish must show no appreciable discoloration, stain or whitening that will not disperse with ordinary polishing and no indication of blistering, checks or other film failure.
- To test the ability of the finish to withstand long periods of exposure to a detergent and water solution, a cabinet door edge is subjected to exposure to a standardized detergent formula for 24 hours. The door edge must then show no delamination or swelling and no appreciable discoloration or evidence of blistering, checking, whitening, or other film failure.
