Scope
QC/T 1008-2015 is the English-translated version of 油箱通风用过滤器技术条件.
QC/T 1008-2015 covers the ventilation filters fitted to automotive hydraulic oil tanks, setting their technical requirements, test methods, inspection rules and the rules for marking, packaging, transportation and storage.
Clause 1 applies it to filters whose volume flow rate is not greater than 6 000 L/min, and lets other tank ventilation filters be checked against it too.
Clause 4 fixes the internal cleanliness and the dust holding capacity, read with ISO 12103-A4 test dust once the filter reaches a final blocking resistance of 3.5 kPa or its filtration efficiency falls to the stated value.
It also asks that 24 h at (80 °C ± 3 °C) and 24 h at (-40 °C ± 3 °C) leave the coating of the enclosure unbroken and the paper element free of fracture or scattering, with burning and scorching also excluded after the high temperature test, while the vibration test uses the parameters of clause 10 of QC/T 32-2006.
Clause 6 splits exit-factory inspection, sampled to GB/T 2828.1, from type inspection. Issued on 14 July 2015, it has applied since 1 January 2016.

4 Technical requirements
4.2.3 Dust holding capacity
Under the rated air flow, the dust holding capacity of filters shall be as specified in Table 2 when the resistance of filters achieves the final resistance of blocking 3.5 kPa or the filtration efficiency of filters drops to the specified value.
4.2.4 Thermal resistance
4.2.4.1 High temperature resistance test
After high temperature resistance test at (80°C ± 3°C)/24 h, the coating of enclosure shall not crack, bubble or fall off; the paper filter element shall be free from burning, scorching, fracturing, scattering, etc.; filter material and adhesive, end cap and adhesive shall not break apart and fractures, cracks, breakages, etc. are not allowed.
4.2.4.2 Low temperature resistance test
After low temperature resistance test at (- 40°C ± 3°C)/24 h, the coating of enclosure shall not crack, bubble or fall off; the paper filter element shall be free from fracturing, scattering, etc.; filter material and adhesive, end cap and adhesive shall not break apart and fractures, cracks, breakages, etc. are not allowed. […]
Mount filters according to the formal installation method; no defects are allowed after vibration test based on the parameters of Clause 10 of QC/T 32-2006, such as fractures and deformations.
5 Test methods
5.2.2 Low temperature resistance
Place a new filter into a low temperature test chamber for test at (- 40°C ± 3°C)/24 h; observe the changes of appearance after test.
6 Inspection rules
6.1 Exit-factory inspection
6.1.1 Each filter shall pass the inspection of the quality inspection department according to 4.1 and be accompanied by a certificate of compliance before delivery.
6.1.2 Sampling scheme shall be as specified in GB/T 2828.1.
6.2 Type inspection
6.2.1 In one of the following cases, carry out type inspection.
a) during the trial-production pattern evaluation of a new product;
b) when there is any significant change in structure, material and process during normal production, which may influence the performance;
d) when there is any significant difference between the results of exit-factory inspection and those of last type inspection;
e) when a national quality supervision body asks for type inspection.
6.2.2 Items of type inspection
The items are as specified in Clause 4.
7 Marking, packaging, transportation and storage
7.1 Each filter shall be marked with.
a) emblem mark or trademark;
b) product type;
c) permanent mark;
d) instructions for use. […]
