【中英对照】国际实验室:羽绒羽毛测试误差规定
实验室里羽绒羽毛测试误差规定详情如下:
测试误差
Content Analysis
含量分析
The International Down & Feather Bureau (IDFB) allows a ± 2-3% testing tolerance when certifying laboratories around the world. This means that if a sample is actually 80% down laboratories that test 78% down or 82% down would be in this acceptable testing range.
国际羽绒羽毛局(IDFB)对全球范围内认证过的实验室允许有正负2-3%测试误差。这意味着如果样品实际含绒量为80%,而实验室测试结果含量为78%或82%,这个测试范围内结果都是可接受的。
Specie ID
绒毛种类
IDFL has proposed a ±5% testing tolerance for Specie tests. In some of the cases of mixed specie the differences have been higher.
IDFL建议在测试绒毛种类时,有±5%误差。在一些混合绒毛产品的案例,差异会更高些。
Oxygen Number
耗氧值
This test gives pretty consistent results. A difference of 1 point might occur.
测试要求完美一致的结果。可能会有1点的差异出现。
Turbidity
浊度(清洁度)
This is a qualitative test. Tolerance might be ± 2-3%.
这是一个定性的测试。允许误差在±2-3%之间。
Fill Power
填充物蓬松度
A 5% testing tolerance is reasonable. For finished products a longer "conditioning" time is necessary to have a proper reading. Therefore final results are not possible for 5 days.
测试误差在5%是合理的。
Net Fill
填充物净重
The process of filling a pillow, comforter or jacket is prone to differences in net filling material. A 5% variance is possible.
在加工填充一件夹克、床垫或枕头过程中填充原料的净重会有不同。5%差异可能存在。
Net fill testing tolerances are affected by humidity. If a piece if filling in a humid climate and tested in a dry climate, the weight of the filling material can be lower.
填充物净重测试会因潮气影响有差异。如果一件单品在潮湿的气候下填充而在干燥的气候中测试,填充物原料的重量会下降。
For example, if a comforter is filled with 1000 grams of material at a plant with 90% humidity the moisture content of the fill material might be 18%. (This means that 180 grams of the 1000 grams is moisture) Then the comforter is tested in a 50% humidity lab. The moisture content of the down drops to 10%. 80 grams of moisture evaporate and the down weighs approximately 920 grams.
举例:如果一件物品在湿度为90%车间里填充了1000克原料,那么填充物湿气含量可能为18%。(这意味着1000克中的180克为湿气)。然后物品在湿气为50%的实验室中测试。湿气含量下降至10%。80克湿气蒸发了,羽绒重量大约为920克。
Thread count
纤维密度
The testing tolerance is ± 5%.
测试误差为± 5%。
Fabric/Textile Tests
织物/纺织品测试
The FTC has set a ±3% tolerance for fiber content, etc of various claims on fabrics.
FTC规定纤维含量±3%误差,对面料还有其他要求。
