At present, there are many types of cut-resistant gloves on the market. Is the quality of cut-resistant gloves good? Which one is not easy to wear out? How to choose to avoid wrong selection?
Some cut-resistant gloves on the market have the word “CE” printed on the reverse side. Does “CE” mean a certain type of certificate?
The “CE” mark is a safety certification, which is regarded as a passport visa for manufacturers to open and enter the European sales market. CE means European unity (CONFORMITE EUROPEENNE). Originally CE was the meaning of the European standard, so in addition to the en standard for cut-resistant gloves, what other specifications must be followed?
The safety protection gloves for preventing mechanical equipment injury must comply with EN 388, the latest version is the 2016 version number, and the American standard ANSI/ISEA 105, the latest version is also 2016.
In these two specifications, the expression of the level of cut resistance is different.
The cut-resistant gloves verified by en standard will have a large shield pattern with the words “EN 388″ on the top. The 4 or 6 digits of data and English letters at the bottom of the giant shield pattern. If it is 6-digit data and English letters, it indicates that the new EN 388:2016 specification is used, and if it is 4-digit, it indicates that the old 2003 specification is used.
The first 4 digits have the same meaning, which are “wear resistance”, “cut resistance”, “resilience”, and “puncture resistance”. The larger the data, the better the characteristics.
The fifth English letter also indicates “cut resistance”, but the test standard is different from the test standard of the second data, and the method of indicating the cut resistance level is also different, which will be described in detail later.
The sixth English letter indicates “impact resistance”, which is also indicated by English letters. However, the sixth digit will only appear when the impact resistance test is carried out. If it is not carried out, there will always be 5 digits.
Although the 2016 version of the en standard has been applied for more than four years, there are still many older versions of gloves on the market. The cut-resistant gloves verified by new and old users are all qualified gloves, but it is strongly recommended to choose cut-resistant gloves with 6-digit data and English letters to indicate the characteristics of the gloves.
With the advent of a large number of new materials, it is necessary to be able to classify them delicately to show the cut resistance of gloves. In the new classification method, there is no difference between A1-A3 and the original 1-3 basis, but A4-A9 is compared with the original 4-5, and 6 levels are used to divide the original two levels. Cut resistance carries out a more detailed classification and expression.
In the ANSI specification, not only the level of expression, but also test standards are upgraded. Originally, the ASTM F1790-05 standard was used for testing, which allowed testing on TDM-100 equipment (test standard called TDM TEST) or CPPT equipment (test standard called COUP TEST). Now ASTM F2992-15 is applied, and only TDM is allowed. TEST carries out testing.
What is the difference between TDM TEST and COUP TEST?
COUP TEST uses a circular blade with a working pressure of 5 Copernicus to flip the laser cutting on the glove material, while TDM TEST uses a cutter head to press on the glove material at a different working pressure, back and forth at a rate of 2.5 mm/s. laser cutting
Although the new EN 388 standard requires the use of COUP TEST and TDM TEST two test standards, but under COUP TEST, if it is a high-performance anti-laser cutting raw material, the circular blade is likely to become blunt, if laser cutting After 60 laps, the tool tip becomes blunt after calculation, and TDM TEST is mandatory.
It must be noted that if TDM TEST is carried out for this excellent laser cutting resistant glove, then the second place of the verification pattern can be written with “X”. At this time, the cut resistance is only indicated by the English letter in the fifth place. .
If it is not for the excellent cut-resistant gloves, it is unlikely that the raw materials of the gloves will blunt the cutter head of the COUP TEST. At this time, the TDM TEST can be omitted, and an “X” is placed on the fifth position of the verification pattern.
For non-cutting gloves with excellent performance, neither TDM TEST nor impact resistance testing has been carried out. ↑ The raw material of cut-resistant gloves with excellent performance. TDM TEST was carried out, but COUP TEST and impact resistance tests were not carried out.
