This standard is applicable to the evaluation of the results after the weathering test of passenger cars. The evaluation of weather resistance of other types of vehicles can refer to the application.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only the dated version applies to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. QC/T 728-2005 Test method for atmospheric exposure of automobile3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Automotive weatherability The ability of a vehicle to withstand the damaging effects of the climatic environment is generally tested and evaluated by the typical atmospheric exposure test of the vehicle. 3.2 Organoleptic quality The quality of the driver's occupants such as visual, olfactory, tactile, and auditory, such as the appearance and smell of the vehicle. The Class quality can cause users to complain, but does not affect normal use, and less maintenance costs (except severe odor). 3.3 Functional quality The ability of an automobile machinery or electrical appliance to function properly. This type of quality problem will have a certain impact on consumer use, attenuation A lighter degree will cause users to complain, and a heavier one will result in maintenance costs, but it will have no significant impact on vehicle safety and reliability. 3.4 Safety quality Quality associated with normal contact with the vehicle or the safety or physical and mental health of the person using it. This kind of quality problem will cause users to complain or even Initiate a recall.4 vehicle air exposure test requirementsT/CSAEXX-2019 Refer to the relevant requirements of QC/T 728 to place the whole vehicle statically in China's typical damp heat (such as Hainan Qionghai) and/or dry heat (such as Xinjiang). Turpan) The climate test is carried out in the climate zone. It is recommended to conduct a vehicle weathering inspection every 2 months or 3 months.5 Vehicle performance test for individual exposure test5.1 Component and material grade single performance rating 5.1.1 Sensory quality rating Sensory ratings for parts and materials include the following. a) Refer to Appendix A for specific expressions of sensory quality changes in parts or materials. b) Uniform changes visible on the surface of the vehicle body, such as loss of light, discoloration, chalking, etc., are rated by the degree of change, see Table 1. c) Non-continuous or local irregular changes in the surface of the vehicle body, such as blistering, cracking, rusting points, etc., are rated by the number of changes, see Table 2. d) If the type of change has a quantitative significance of magnitude, plus the assessment of the magnitude of the change, see Table 3. e) The representation of changes in weatherability should include the following. type of damage, degree of damage, or level of change. To indicate change Size grades are indicated in parentheses. Example. "Gloss. 2" in uniform change means loss of light 2; blistering level in scatter (quantity, size) change "bubble. 2 (S3)" The number of bubbles is 2, and the foaming size is 3 levels. Table 1 Level of uniform change Degree of change 0 no change, no noticeable change 1 very slight, that is, just noticeable changes 2 slight, that is, sensible aging 3 medium, that is, there is a noticeable aging 4 is larger, that is, there is a big change 5 serious, that is, there is a strong change Table 2 Quantity change level Number of levels change 0 no, ie no visible change 1 less, that is, just some notable changes 2 less, that is, there are a few notable changes 3 medium, that is, there is a moderate amount of change 4 more, that is, there are more changes 5 dense, that is, intensive changes Table 3 Size change level Level change size No visible change under S0 10 times magnifying glass S1 10 times magnifying glass visible changes S2 just visible changes under normal vision S3 Significantly visible changes under normal vision (< 0.5mm) T/CSAE XX-2019 S4 variation from 0.5mm to 5mm S5 > 5mm change 5.1.2 Functional Quality Rating For the evaluation of the functional attenuation level of components, see Table 4. Table 4 Component function attenuation level Degree of attenuation 0 no, that is, there is no obvious functional attenuation 3 Obviously, the function attenuation can be clearly felt, but it can still be used. 5 serious, the function can not be played properly, consumers can not use 5.1.3 Safety Quality Rating For the safety quality rating of parts, see Table 5. Table 5 Parts safety quality level Degree of attenuation 0 None, safe and reliable performance related to vehicle safety Serious, there are potential safety hazards, for normal contact with the vehicle or for the safety of the person or for physical and mental health There is a security risk. 5.2 Vehicle-level single performance rating The vehicle-level single-item performance mainly refers to the smell inside the car, which belongs to the sensory quality of the car. The evaluation of the odor level in the car is shown in Table 6. The evaluator is allowed. The staff gives a value of 0.5. See Appendix B for the relevant requirements for odor evaluation. Table 6 Odour level Grade odour level 0 odorless 1 has a slight odor (almost unrecognizable smell) 2 has an easy to recognize smell, but no discomfort 3 has a distinct smell, which makes people feel uncomfortable 4 has a strong smell, it is offensive5 have an unbearable smell6 Vehicle weatherability score calculation6.1 The weatherability score of the whole vehicle is calculated from the three evaluation dimensions of sensory quality, functional quality and safety quality. 6.2 Sensory quality, functional quality and safety quality The three-point scores of the three dimensions are all 100 points, and the right in the vehicle weatherability score The weights are 30%, 30% and 40%. 6.3 Sensory quality The weight of the high visible or high contact area, the visible or medium contact area and the low visible or low contact area is 70%, 20% and 10%. See Appendix C for definitions of each region. T/CSAEXX-2019 6.4 The scores of the single-item performance 0 to 5 are shown in Table 7.
