Maharashtra Stale, India An Indian Company registered under the provisions of the Companies Act, 1956 The following specification particularly desires the natiuire of this invention and the manner in which it is to be performed:- ORIGINAL 941/MUM/2002 GRANTED 29-4-2004 The present invention relates to an apparatus for testing the decorative automotive components for their combined effects of chemicals and mechanical wiping and for the purpose of predicting the life of a decorative automotive component Following examples illustrate the deterioration of various decorative automotive component. 1. Automotiv vehicles are frequently washed with different solution such as detergents or soap and wiped with soft cloth. This action affects glazing of chrome plating on componentsp Such as name plates on door handles and logos. this is the combined effect of chemicals and mechanical wiping. 2: when automotive vehicles are brought into garages for maintainance and repairs; some of the decorative components such as swiwith screen- printed or etched labels are smeared with oils/grease /brake fluids /thinner/diesel/petrol. As a result appearance of these components gets affected. 3. Many times components (like knobs on combination switches, key heads and other switches to operate power windows, hazard indicators) are operated with hands smeared with oily eatables or soft drinks which are acidic or alkaline in nature This deteriorates the appearance of these components. In 'prior art, there exits no apparatus for such testing However testr processes in the form of standards are known for testing plastic material under the action of different chemicals. For examle the American standerd ASTM 543-87 describes changes in properties like weight and dimensions of polyproplylene or ABS plastic material strip when it is dipped in chemicals such Acetic acid, Ammonium Hydroxide, Aniline, Benzene, and Carbon Tetrachloride: However the available Standerd does not described the combined effect of chemicals and mechanical wiping that happens in real life..

The Apparatus: The apparatus is described with the help of the figure 1,which shows the front view of the apparatus. The apparatus for conducting the test consists of following main parts 1 Base frarne 2 Wiping rollers3 Containers 4 Specimeih mounting plate The base frame consist of a mild steel rectangular plate (A) to which two vertical plates (B) are welded . The base frame is mounting on level bolts (M) to maintain the: level of the apparatus Wiping Rollers: Four wooden wiping rollers (D) are mbuhted oh a drive Shaft (C) supported between the vertical plates (B). The wiping rollers (D) are spaced away from each other by bushes (H). The distance between two rollers can be changed by using shorter or longer bushes, as required. A soft cotton cloth is wrapped around the wooden rollers. Sheet metal discs are provided on either side of each roller to avoid slipping of the cloth during wiping A D.C motor ( E ) mounted on one of the vertical plate (B). This drives the drive shaft (C) for rotating the wiping rollers. It is to be noted that the size of the specimen to be tested cannot be more than the length of the wiping roller. These wiping rollers may be replaced by wiping duster for linear movement. Containers: Four plastic: removable containers ?(F)are mounted oh the base plate (A) using bottom brackets (J). Chemicals are stored in thesse removable containers. AD.C. motor driven pumpp is provided to each container for pumping chemical on each roller through plastic tubes (L ) Plastic tubes are held in position by passing through a fabricated sheet metal channel. A wiping cloth on each rollers is required to be kept tvet with the chemical. Flow of chemicals is controlled by changing the speed of the motor An electronic timer is provided to control the duration of chemical flow. The chemical falling down from' the roller during test is collected irf the contaner: The angle of the container is adjustable to facilitate collection of chemical falling down from roller. Mounting of the test specimen: Two mounting; plates (G) which are bolted to vertical plates (B) , are provided on either side of the wiping rolled (D). Provison is made so that test specimen (N) is bolted to the mounting plate. A Total Pf 8 specimens can be mounted on these two plates'. Chemicals The chemicals which normally come in contact with automotive decorative components are: • Detergent • Soap • Brake fluid • Diessel • Petrol • Thinner • Soft drink • Edible oil • Acetic acid • Aniline • Car1>otiTetfacMoMdie ■ Benzene This is not an exhaustive list of chemicals. It is not intented to preclude the use of any other chemical pertinent to a particular requirements. Descriptiion of the process: 1. Duration : of test process Duration of test for a particular specimen is to be worked out in the following manner A Logo on a bonnet of an automobile may be wiped for 10 times a day, with each wiping lasting for2 (two) second .sl Hence in one year, the duration of wiping would be 7,300 seconds or 21.02 hours. The expected life of Logo of service vehicles is 10 years Therefore the duration of combined action of chemical and mechanical wiping is 2.0210=20.2 hours . (say21 hrs) Thus the test duration of test for Logo is decuded as 21 hours for combined effect of chemicals and mechanical wiping This is the accelerated testing. Hence following stepsare necessary during the test prbeess:; a) Mount the specmien sucn that it comes in contact t with the wiping roller. b) Inspect the specimen during test after every l-hrs for its deterioration. 2. The face of the component is decided for combined effect of chemicalss and mechanical wiping. 3. The size of the cbmponent is decided oil the basis of the mounting arrangement on test rig The size has to be suitable for the wiping action on the rig Since the component is to be tested for various chemicals, there would be a number of samples pf such component depending uponi the number of chemicals. 4. The test is carried out for the pre calculated life; 5. The test is repeated for different types of chemicals. 6.
