4 Technical requirements

4.1 General requirements The technical requirements of the canister air filter shall comply with the provisions of this document. 4.2 Original resistance Under the rated air volume flow rate, the original resistance of the canister air filter shall not be greater than 150 Pa. 4.3 Filtration efficiency Under the rated air volume flow rate, when the intake resistance reaches 750 Pa, the filtration efficiency of the canister air filter shall not be less than 99%. 4.4 Ash capacity Under the rated air volume flow rate, when the air intake resistance reaches 750 Pa, the ash holding capacity of the canister air filter shall not be less than 21 g, OR as agreed upon by the supplier and the buyer. 4.5 Structural integrity of filter element The initial bubbling pressure of the carbon canister's air filter element shall be as 5.1.6.1.3 The original resistance is the static pressure value, which is measured at the pressure measuring point, downstream of the test piece. During the test, measure and record the static pressure value of the downstream pressure measuring point, under each air flow, based on 50%, 75%, 100%, 125%, 150% of the rated air flow (or as agreed between the supplier and the buyer). 5.1.6.1.4 Record the ambient temperature, relative humidity, atmospheric pressure during the test. 5.1.6.2 Filtration efficiency 5.1.6.2.1 Properly connect the test piece with the test bench, according to Figure 1. 5.1.6.2.2 Start the air extractor, to pump air at the rated air flow rate for at least 15 minutes, to stabilize the state of the test piece. 5.1.6.2.3 Weigh the test piece and the absolute filter. Record the initial mass of the test piece and the absolute filter. 5.1.6.2.4 Properly connect the ash adding tooling, test piece and test equipment. 5.1.6.2.5 Start the test bench. Adjust the flow rate to the test flow rate and make it stable. Record the resistance value. 5.1.6.2.6 Start to add ash to the air. The ash concentration is l g/m3, OR according to the ash concentration, which is agreed upon by the supplier and the buyer. 5.1.6.2.7 Continue the test, until it reaches the specified test termination resistance value of 750 Pa. 5.1.6.2.8 Weigh the test piece and the absolute filter. Record the mass of the test piece and the absolute filter, after the test. Calculate the mass increment of the test piece and the absolute filter. 5.1.6.2.9 Calculate the filtration efficiency, according to formula (1) Where: E - Filtration efficiency, in percentage (%); ΔmU - The mass increment of the test piece, in grams (g); ΔmF - The mass increment of the absolute filter, in grams (g). 5.1.6.2.10 Record the ambient temperature, relative humidity, atmospheric pressure during the test. 5.1.6.3 Ash capacity 5.1.6.3.1 The ash holding capacity test can be carried out, simultaneously with the filtration efficiency test. 5.1.6.3.2 Weigh the test piece and the absolute filter. Record the initial mass of the test piece and the absolute filter. 5.1.6.3.3 Properly connect the ash adding tooling, test piece, test equipment. 5.1.6.3.4 Start the test bench. Adjust the flow rate to the test flow rate and make it stable. Record the pressure difference. 5.1.6.3.5 Start to add ash to the air. The ash concentration is 1 g/m3, OR according to the ash concentration agreed upon by the supplier and the buyer. 5.1.6.3.6 Continue the test, until the specified test termination resistance value is reached. 5.1.6.3.7 Weigh the test piece and the absolute filter. Record the mass of the test piece and the absolute filter, after the test. 5.1.6.3.8 Calculate the ash capacity C, according to formula (2): Where: C - Ash capacity, in gram (g); B - The mass of the test piece after the test, in grams (g); D - The mass of the test piece before the test, in grams (g). 5.1.6.3.9 Record the ambient temperature, relative humidity, atmospheric pressure during the test. 5.2 Low temperature impact resistance Place the canister air filter in a low-temperature box at -30 °C ± 2 °C for 4 hours. Within 30 seconds after taking out, according to the requirements of the test Ehc: vertical drop weight in Chapter 6 of GB/T2423.55-2006, carry out the drop weight impact test on the visible surface of the canister air filter, at room temperature. The standard drop weight is a steel ball, which has a mass of 500 g and a free fall height of 0.4 m. The drop weight impact point is at a visible surface position of the canister air filter. After the test, check whether the canister air filter is cracked or deformed. 6.3 Exit-factory inspection The exit-factory inspection item is 4.10. 6.4 Type inspection The type inspection items are all items specified in Chapter 4. In case of any of the following situations, type inspection shall be carried out: a) Type identification of new products; b) After normal production, if the product structure, material, process have changed significantly, which may affect the product performance; c) According to the requirements of the product audit quality control plan, when the periodic performance inspection is required; d) When the national quality supervision agency requests type inspection; e) When requested by the user. 6.5 Spot check When the buyer conducts spot check on product quality, it shall conduct spot checks in accordance with the provisions of GB/T 2828.1-2012. The inspection items, group- batching principles, sampling plans, judgment and re-inspection rules shall be implemented, in accordance with the technical documents, which are agreed between the manufacturer and the customer.
