GB/T 30126-2013Textiles—Testing and evaluation for anti-mosquitoes properties (English PDF)

3.1 Anti-mosquitoes properties

It refers to the product features of knocking down, killing, and repelling mosquitoes, etc.

3.2 Control fabric

It refers to the fabrics used to compare the anti-mosquitoes properties with the samples to be tested.

6.1 Constant temperature and humidity laboratory

It can maintain a certain test temperature and relative humidity; the temperature accuracy is ± 1 °C AND the relative humidity accuracy is ± 10%.

6.3 Repellent tester

6.3.1 The repellent tester is rectangular, 18 cm (length) x 5cm (width) x 4 cm (height); its top is fabricated by the gauze the mesh of which is 20 mesh ± 10 mesh; whilst its side surface, end plate, and bottom surface are fabricated by transparent materials; REFER to Figure 2.

6.5 Forced contactor

Forced contactor complying with GB/T 13917.1-2009.it is used to knock down AND kill test.

6.6 Other

6.6.1 Mosquito suction tube

6.6.2 Commonly used laboratory equipment such as measuring cylinder AND flask, etc.

6.6.3 Stopwatch, counter

6.6.4 Scissors

6.6.5 5% sucrose solution.

7.1 Mosquito species

Aedes albopictus, the female adult mosquito which is 4 d ~ 7 d after emergence AND does not suck blood;

7.2 Indicated information

The mosquitoes used for test purposes shall be indicated of the following information.

8.1 Sample size and quantity

8.1.1 Repellent tester method

SELECT representative samples from each sample; CUT a 4 cm x 4 cm square as a sample. Respectively TAKE 8 anti-mosquitoes fabric samples to be tested AND 8 control fabrics.

8.2 Sample pretreatment

After placing the sample at 26 °C ± 1 °C for 10 min, CONDUCT test.

8.3 Treatment of anti-mosquito effect washability sample

If evaluating the fabric's anti-mosquito washable performance, WASH the sample to be tested in accordance with the sample conditions A1M of GB/T 12490-2007;

10.1 Repellent method

10.1.1 Repellent tester method

10.1.2 Blood-sucking insect feeding device method

In the 2 blood feeding boxes of the blood-sucking insects feeding device (6.4), respectively ADD 10 mL of blood; USE artificial membrane to seal the blood; respectively COVER the sample to be tested AND the control fabric over the artificial membrane of the blood feeding box.

10.2 Forced contact method

USE the forced contactor to conduct test in accordance with the steps as specified in 4.3.3.1 of GB/T 13917.1-2009. The test mosquitoes are Culex pipiens pallens, and USE the sample to substitute the reagent contact surface.

11.1 Result calculation

Based on the selected test, USE the equation (1) to calculate the sample's repellent ratio against mosquitoes; USE the equation (2) and (3) to calculate the sample's knock-down ratio and kill ratio against mosquitoes; KEEP one decimal place. […]
