MATERIALS AND PROCESSES TEST REPORT w TO: AM Stone AP1-234A DATE: March 4, 1982 LAB REPORT NO. CA-2-060 SUBJECT: Friction Materials from Competitive Washers BACKGROUND: t'l CPSC Is getting ready to resume examination of some consumer products containing asbestos. Nine samples of friction materials from four competitors washing machines are to be examined for asbestos content. REQUEST: 1. Determine if asbestos is present. 2. If asbestos is present, determine resin/asbestos/other filler concentrations. IDENTIFICATION: Friction materials submitted for asbestos analysis are as follows: Sample # - Whirlpool LA58Q0XK - Received 10/81 1. Shifter button 2. Clutch lining 3. Brake lining - Wards 6431 - Received 1/17/82 4. Node dumping material 5. Basket brake {coarse woven material , - Kenmore 11611 Received 1/17/82 6. Tub damper material (pad, base 62602) 7. Clutch lining 8. Brake lining - Speed Queen HA70G1 - Received 10/12/81 9. Brake CEPTEST RMl',JAW M.
