How To Interpret The Results Of India Fiber Inspection

The world is full of regionalism. fibre Products, and detection and design methods are also odd. In many non developed countries, especially in countries like India, large and small fiber producers mostly adopt self determination tests. standard 。 Generally speaking, they use the average of the test as the approved result and use it as a basis for reporting to the customer. The average value is determined by the comparison of the test data according to the requirements. Therefore, the production of fiber products often with a strong regional characteristics, the local standards and testing methods play an important role in quality. Therefore, how to correctly interpret the test results of these regional products is very important.

　　 Uncertainty

In India, the uncertainty of fiber quality is regarded as an important parameter. The result of detection depends entirely on the standard of self determination. In other words, the detection of fiber in India depends to a great extent on the trust of the boss to the laboratory, rather than the objective data. Most of the time, uncertainty is considered as a quantitative result detected in a single laboratory using a single test method. The most important phenomenon of the test results is that many manufacturers compare their laboratories with the laboratories of many competitors, and then give specifications and reference values.

In interpreting the uncertainty of the test results, the India textile fiber laboratory also takes customer perceptions and perspectives as data. For example, if accidental differences are found and there is uncertainty in their results, they are often unable to distinguish the real difference between their real characteristics and their performance from the comparison results of different batches of fiber materials. Uncertainty also lies in other parameters that affect the outcome. In order to calculate the uncertainty factors, of course, we must first identify the parameters that affect the test results. These uncertainties come from the following aspects: the accuracy of the operator, the equipment, the calibration of the instrument, the environmental conditions, and the accuracy of the rating. The uncertainty of fiber detection in India is also reflected in the equipment used. Generally speaking, uncertainty is the result of a trusted laboratory being incorporated into other non detection factors. In India, simple charts for uncertainty are often mixed with other unexpected factors.

　 Influence of international standards

India has a large number of regional fiber products enterprises. These companies do not really strictly comply with international standards, but are tailored to the local conditions for textile enterprises. For example, ASTM E 2554-07 belongs to the laboratory standard standard. It sets out the requirements of the control sample for estimating and monitoring single laboratory tests. As a result of the uncertainty factors calculated by each single method, there are different test dates and different data collected by different inspectors in India. This makes the uncertainty of India fiber detection more complicated. Human subjective factors take part in it. This is also one of the main reasons for the obvious regional characteristics of India's fiber products. Therefore, India's fiber inspection is often different from international standards. The test reports in India not only attach importance to the average value, but also use customer impression as one of the reference data to confirm the market interpretation of the product. Therefore, international standards such as ASTM have little impact on India's regional products.

　　 How to interpret test results

Indians often use individual examples to describe common phenomena. Under normal circumstances, the average local accreditation often takes the place of international standards. Once they meet their requirements, they will think it has become an international standard product.

Most of the time, the uncertainty of products has been regarded as the decisive factor of fiber quality. If UCL and LCL are regarded as limited values, the strong regional character of fiber production in India is even more obvious. The LCL test in India also shows that sometimes the test results may exceed the defined requirements, which are still attributable to uncertainties. This is why the same sample can be measured in the laboratory, and the same time does not meet the requirements in the same laboratory at the same time, and does not include laboratory errors.

Therefore, interpreting the results of India fiber test should not only use the average value, but also consider other uncertain factors.

The India national textile and textile department has made it clear that it should do its best to reduce the uncertainties of fiber, and it must also accurately locate the cause of uncertainty, that is, the variability of products. In the field of India nonwoven fiber materials, the uncertainty of quality is particularly obvious. They believe that if product variability becomes the main factor of uncertainty, the only way to reduce uncertainty is to increase the number of test samples.

When a product fails to meet the specifications, it is hard for Indians to attribute it to the laboratory. And in interpretation test When considering the associated specifications, they consider other factors more than the accuracy of the test parameters. Therefore, they think it is necessary to increase the quantity of test samples when considering the variability of products. Only a large quantity of product testing can make the test data more accurate under the same variability condition, so as to meet the standard.
