Who Should I Consult For Glove Testing?
Recently, some foreign suppliers often ask me, “Does your company do Glove testing consultation?” The answer is of course there is! Considering that everyone has a lot of doubts about the glove product, so write an article to share some knowledge about Glove testing consultation. For details, you can contact us directly.
Due to COVID-19, protective products such as gloves and masks have become hot products during this period. People buy in large quantities or even hoard goods, resulting in a shortage of goods. Chinese mask manufacturers made a lot of money. As the class gradually solidifies and it becomes more and more difficult to become rich overnight, accurately predicting market hotspots and seizing business opportunities are important ways to accumulate wealth. There is an old Chinese saying that “seeking wealth and danger” means this.
For consumers, the most important thing is the product quality, but for importers, the product quality is the most uncontrollable factor. The third-party inspection company, with its professional team and sufficient quality control experience, can solve this problem for importers. The inspection contents of the third-party inspection company are divided into laboratory tests and ordinary appearance function tests. laboratory tests consider the internal quality of products, with high price and small number of tests. while ordinary appearance function tests consider batch problems, with relatively low price. some third-party inspection companies without laboratories can also provide them laboratory consulting services. Taking gloves as an example, this article briefly describes the relevant contents of glove laboratory tests. If you are preparing to import gloves from China or want to know about Glove testing consultation service, this article is very suitable for you to read.
Glove testing consultation mainly includes testing price and testing items. And the test price depends on the quotation of the laboratory. Third-party inspection companies with close relations with laboratories can get better discounts and provide better consulting services to importers. The test items will vary according to the imported national standards. It should be noted that the following glove standards are from the International Organization for Standardization and can be consulted.
1.Technical Requirements-Glove Testing Consulting
First, the standard clearly requires that the design and manufacture of gloves should fully consider the use requirements, so that users can be protected to the maximum extent and have operational flexibility in carrying out related operations. If necessary, gloves should be worn and removed at least in time.
Second, when the structure of the glove adopts seam, the strength of the seam should not significantly reduce the overall performance of the glove. Moreover, it is required that the parts of the glove that are in close contact with the user, such as the inner lining, thread and welt of the glove, should not harm the safety and health of the user. If the manufacturer knows that the glove contains allergic substances, it should be indicated in the glove instructions.
Third, it is stipulated that the pH value of all gloves should be as close to neutral as possible. For example, the pH value of leather gloves should be 3.5 ~ 9.5.
Fourth, the determination of hexavalent chromium and protein content is stipulated for gloves with different compositions.
Fifth, if there are cleaning and electrical performance requirements, there are also corresponding testing methods and requirements.
Sixth, glove sizes of 6 specifications are specified according to different sizes of hands.
Seventh, the requirements of water vapor permeability and water vapor absorption. The water vapor permeability value of leather gloves shall be above 5 mg/(cm2/h), and the water vapor absorption value within 8 h shall be not less than 8 mg/cm2.
2.Test Methods-Glove Testing Consulting
Unless there are special requirements, all tests shall be carried out on unused gloves. If there are relevant provisions in the product description, the test shall be carried out according to relevant standards before cleaning and after cleaning the specified number of times respectively. The corresponding criteria for determining performance levels remain unchanged.
First, the pH value of leather gloves is determined according to the method specified in ISO 4045:1977.
Second, hand and glove size measurement. The glove length is measured from the top of the middle finger on the back of the glove to the bottom of the glove. If the glove is made of elastic material, or if the glove has an elastic wrist guard, measuring the length of the glove should be performed on a sample without elongation.
Third, flexibility measurement. Measured by 5 polished stainless steel test rods.
Fourth, the principle of water vapor permeability test is that under certain temperature and humidity conditions, the leather test piece is fixed at the moving test bottle mouth, and the test bottle is filled with solid desiccant. When the test bottle moves, water vapor is absorbed by the solid desiccant through the leather test piece, and the quality of water vapor absorbed by the desiccant during this period can be determined by weighing the test bottle within a specified time. The numerical unit is expressed in mg/(cm2/h).
Fifth, the water vapor absorption test method. Water vapor absorption is calculated by the ratio of the added mass of the sample to the test surface area, and the numerical unit is expressed in mg/cm2.
The above content is just a simple popularization of Glove testing consultation and general test items. Glove types are various and can be classified according to different indexes such as material, raw materials, functions, etc. Different types of glove tests are also different. For example, heat radiation resistance and heat penetration resistance are required for heat insulation glove tests. If you want to know more, please contact us.
