National Standard "Determination Of Peculiar Smell Of Wadding Fiber Products" Fills In Blank For Garment Inspection

It is understood that our country's mandatory national standard "national textile products basic safety technical specification", "

What is the flavor of standard mildew and fishy smell? The standard sample of fiber and fiber products odors released in February 2009 is the national standard of standard "odor" samples.

The inspector sniffed the standard samples, and then checked the samples tested according to the relevant requirements.

Of course, it is not necessary to smell the standard samples for each test, but it is necessary to calibrate the olfaction using standard samples as required.

according to

According to the briefing, the standard is jointly completed by the national fiber quality supervision and inspection center, Guangzhou fiber products testing institute and Chongqing fiber textile inspection institute.

The survey showed that the problem of odor detection was mainly detected in the same laboratory in the same sample, and the results of different personnel were different.

The first reason is that some of the inspectors do not know deeply about the smell, and do not know clearly. Two, the sensitivity of different personnel to odor is different, and the intensity of odor is different. Three, there is no detailed description of the odor detection method, and there are no strict restrictions on the environmental conditions of the detection. The peculiar smell is caused by volatilization of some substances in the fiber and its products into the air, and the degree of volatilization is different at different temperatures, and the severity of odor is different.

According to Zhou Shuo, the standard draftsman and the state fiber quality supervision and inspection center, requirements for laboratory equipment and materials, testing environment, sample preparation and inspection procedures are important prerequisites for sensory inspection accuracy.

In particular, the testing personnel made detailed requests, including physical health, normal smell, no smoking, no alcohol consumption, no cosmetic or skin care products were used on the test day, wash hands before testing and remove mouth odor by rinsing mouth with water.

It also stipulates that 2~3 deep breaths need to be taken into the detection environment, and then wait for 10 seconds to suit the testing environment.

In addition, the requirements for the olfactory calibration of the test personnel were put forward. The test personnel who had been engaged in the project for a long time were required to perform a olfactory calibration once a month. The test personnel should be shortened when the test time was changed or the disease was not detected for a long time.

This standard can be combined with "standard samples of fiber and fiber products odor", which can improve the inspectors' discrimination on the types of odor peculiar to the fiber products, including the textiles, and unify the strength of odor and improve the accuracy of odor detection.
