The weather is cold, and it is the season when the down jacket goes on sale.

Taiwan economic and Trade Bureau said that 15 kinds of CNS13982-1 have been announced.

The Taiwan Standard Inspection Bureau said that the higher the percentage of feather down is, the better the degree of warmth is. Because feather down is a natural product and more as an internal filler, it is more necessary to check the consistency between the contents and the product label.

The Taiwan inspection bureau pointed out that due to the different countries in the region, there were differences in the specifications and inspection methods of feather and down products in various countries. The Taiwan inspection and Quarantine Bureau, in accordance with the inspection rules set down by International Down & Feather Bureau (IDFB), formulated 15 national standards such as CNS 13982-1 "feather and down test method - first parts: adjustment" for inspection units, and helped to ensure the protection and rights and interests of buyers and sellers.

Taiwan Standard Inspection Bureau said that the national standards of 15 feather and feather test methods, such as CNS 13982-1, are the determination of fillings such as feather and down products, such as feather down, feather and feather stuffing sleeping bags, down garments (jackets and vests). From the sample's adjustment, sampling, composition, oil content, water content, pH value, oxygen consumption index, fluffiness, suspended turbidity, feather type, feather classification, feather average length, the composition of mixed materials, the color of feather and feather, and the determination of loading net weight, it is clearly judged and quantified, and no fuzzy area will be detected.

For example, according to CNS 2119, the specification of 90/10 waterfowl eiderdown, that is, the down feather of 90% of the products, can be withdrawn from this kind of down clothing. If the fabric of the down jacket has the function of preventing water diversion, it is not necessary to be afraid of sudden rain or snow in the winter and keep warm.
