3 Terms and Definitions
The following terms and definitions apply to this document.
3.1 Wet wipes for kitchen
They refer to the wet wipes used to clean kitchen objects (e.g. gas stove, range hood, etc.).
5.4 Wipes shall not have hair loss, crumbs phenomenon.
5.5 Toxic and harmful raw materials shall not be used in wet wipes. For wet wipes for human body, only natural fiber shall be used as raw materials. Using any recycled fibrous substance as the raw material is not allowed.
6 Test Method
6.1 Treatment of sample
It shall carry out the treatment of sample according to GB/T 10739.
6.2 Length and width deviations
6.2.1 Length deviation
Cut off the outer packing of wet wipes from one end and wipe off the outer packing. Take out the wet wipes in the condition that they are not out of shape. Place them naturally and flatwise on the glass pane. Measure the length of samples with a ruler. There shall be 6 pieces for each same-specification sample. And the accuracy shall reach 1mm. Calculate the percentage of the difference of mean value and nominal value of the 6 samples with the nominal value. That is the determined result of length deviation of the samples, with accuracy to be 1%.
6.2.2 Width deviation
Cut off the outer packing of wet wipes from one end and wipe off the outer packing. Take out the wet wipes in the condition that they are not out of shape. Place them naturally and flatwise on the glass pane. Measure the width of samples with a ruler. There shall be 6 pieces for each same-specification sample. And the accuracy shall reach 1mm. Calculate the percentage of the difference of mean value and nominal value of the 6 samples with the nominal value. That is the determined result of width deviation of the samples, with accuracy to be 1%.
6.2.3 Calculation of length and width deviations
Calculate the length and width deviations according to Formula (1).
Deviation = (mean value - nominal value) / nominal value x 100% ... (1) 6.3 Containing-fluid-volume
Separately and respectively take 1 piece of wet wipe from upper, middle and lower 3 positions of a complete package of wet wipes to constitute a sample (If the single packaged quantity is less than 3 pieces, take the actual pieces of the single package as the sample). After sampling, weigh the sample immediately with a balance with sensitivity of 0.01g. Rinse the sample with distilled water or deionized water till there is no foam. Put it into a drying oven of (85 ?? 2)??C (when drying the sample, it shall not contact with four 8(16) 1 2 -- --

7.4 Determination of acceptability. The sample quantity for the first test shall be equal to the first sample quantity provided in the plan. If the number of unqualified products discovered in the first sample is less than or equal to the first acceptable quantity, then this batch shall be regarded as acceptable. If the number of unqualified products discovered in the first sample is between the first acceptable quantity and the first unacceptable quantity, then the second sample with the quantity provided in the plan shall be inspected; and it is accumulated in the number of unqualified products discovered in the first and second sample. If the accumulative number of unqualified products is less than or equal to the second acceptable quantity, then this batch shall be determined as acceptable. If the accumulative number of unqualified products is more than or equal to the second acceptable quantity, then this batch shall be determined as unacceptable. 7.5 If the purchaser has dispute to the product quality, it shall inform the supplier for joint re-inspection, within 3 months upon receiving the goods; or it entrusts an jointly-agreed inspection body to carry out the re-inspection.
