Temper Test: Washers after being compressed to a height equal to the actual material thickness plus 0.005 inch (0.13 mm), then released, shall have a free height greater than the compressed height. Compression shall b
20、e acomplished between parallel flat surfaces for flat varieties of tooth washers and between mating countersunk holes and cones for countersunk tooth washers. Clamping Test for Plated Washers: Washers shall be clamped to a height equal to the actual material thickness plus 0.005 inch (0.13 mm) for a
21、 period of 24 hours without breaking. The clamping shall be accomplished between parallel flat surfaces for flat varieties of tooth washers and between mating countersunk holes and cones for countersunk tooth washers. Twist Test: Requirements shall be as specified in ANSI B18.21.1 (illustrated below
22、). 6.0 Finish: Plated washers shall be baked four hours at 400F as soon as practicable after plating in order to relieve hydrogen or acid embrittlement. If washers so treated fail to meet the prescribed tests, the baking time and/or the temperature shall be increased. SEPT 1975 Product Engineerlng P

Outside Diameter: The tabulated outside diameter and nib dimensions and tolerances apply only to the largest periphery and not to the tapered breakout area. Runout: Runout between the inside and outside diameters defined above shall be held

Breakout, flatness, height of burr and edge radii, where not defined, must be adequately controlled such that serviceability of washer is unaffected as determined by Product Engineering. Flatness measurement: Difference of thickness measured by the separation of two parallel surfaces and thickness measured by a micrometer at midwall shall not exceed flatness tolerance.
