6 5.2.3 Type II Test (Test for carbo mooxide ad Hydrocarbos emissios at idlig speed) This is applicable oly for spark igitio egied vehicles The carbo mooxide ad Hydrocarbos cotet by volume of the exhaust gases emitted with the egie idlig must ot exceed as per the limits metioed i 4. of Part I of this documet Type III test (durability of ati-pollutio devices) The requiremet of durability must be compiled o all vehicles referred to i para. of this Chapter. This may be established by usig the deterioratio factor otified i CMVR or by carryig out the durability test. The test represets a ageig test of km for 2& 3 wheelers, drive i accordace with the program described i chapter 0, o a test track, o the road or o a chassis dyamometer For all type of 2/3 Wheeler a deterioratio factor as otified i otificatio is applicable. OR The vehicle maufacturer may opt for a ageig test of km for 2/3 wheelers for evaluatio deterioratio factor as described i chapter At the request of the maufacturer, the testig agecy may carry out the Type I test before Type III test has bee completed usig the deterioratio factors give i otificatio. O completio of Type III test, the testig agecy may the amed the type-approval results recorded i the otificatio with those measured i type III test Deterioratio factor are determied usig either procedure i chapter 0 or usig the values i the otificatios at the optio of maufacturer. The factors are used to establish compliace with the requiremets of ad Modificatios of the vehicle Model : 6. Every modificatio i the essetial characteristics of the vehicle model shall be itimated by the vehicle maufacturer to the test agecy which type approved the vehicle model. The test agecy may either 6.. Cosider that the vehicle with the modificatios made may still comply with the requiremet, or Require a further test to esure further compliace. 6.2 I case of 6.. above, the testig agecy shall exted the type approval coverig the modified specificatio or the vehicle model shall be subjected to ecessary tests. I case, the vehicle complies with the requiremets, the test agecy shall exted the type approval. 6.3 Ay chages to the procedure of PDI ad ruig i cocerig emissio shall also be itimated to the test agecy by the vehicle maufacturer, wheever such chages are carried out.
