What do the details on a chemical protective glove actually mean? Anyone choosing gloves to EN ISO 374 will find standard numbers, letter codes and strings of digits on the packaging and data sheet. Using three models from our chemical protective gloves category, this guide shows where this information appears, how to read it and which questions to settle before you choose.
Where to find the marking
The marking appears in three places: in the product name, in the manufacturer's data sheet and on the product page in our shop. For the NITRAS SAFETY models shown here, the name already contains two standards, EN 388 and EN ISO 374. Only the data sheet gives the full details: part 1 of EN ISO 374 with a type and a letter code, on some models also part 5 with the addition VIRUS, and finally a code for EN 388.
The product name alone is therefore not enough to make a choice. Two gloves with almost identical names can differ in exactly these details. The comparison further down shows this clearly.
It is also important to remember that these details describe test results under defined conditions. Whether a glove suits your substance, your concentration and your wearing time only becomes clear when you compare it with your risk assessment and the manufacturer's information.
Reading the parts of the marking
- EN ISO 374-1 with type and letters: This is the core of the marking. The letter code differs from model to model. The meaning of each letter is defined by the standard. Ask the manufacturer to confirm the assignment before you use a glove for a specific substance.
- EN ISO 374-5 with VIRUS: This part is listed in the data sheets for GREEN BARRIER and GREEN BARRIER FLEX. According to the manufacturer's description, both protect against microorganisms, bacteria and viruses. For the GREEN BARRIER GRIP model, the data sheet does not list this part.
- EN 388 with a code: The digits and the letter after EN 388 form a separate test code. What each position means is set out in the standard. Only compare these codes between gloves whose data are given to the same standard.
- Material and length: These details also matter for your choice. The two GREEN BARRIER models are nitrile gloves with a length of 33 cm, while the GRIP model is made of cotton tricot with a double nitrile coating and is 32 cm long.
Three models and their details
The overview below puts the details from the product data side by side. At a glance you can see where the models differ despite their similar names.
| Detail | GREEN BARRIER | GREEN BARRIER FLEX | GREEN BARRIER GRIP |
|---|---|---|---|
| Material | nitrile, green, velourised | nitrile, green, velourised | cotton tricot with nitrile coating |
| Length | 33 cm | 33 cm | 32 cm |
| EN ISO 374-1 | Type A: AKLMNO | Type A: JKLMNO | Type A: AJKMNO |
| EN ISO 374-5 | VIRUS | VIRUS | not listed in the data sheet |
| EN 388 | 4101X | 2101X | 4121X |
| Size range | 07 to 11 | 07 to 11 | 08 to 11 |
| Packaging unit | 144 pairs | 144 pairs | 72 pairs |
The values come from the manufacturer's information for our products. The relevant product page and the current data sheet always take precedence.
Step by step to the right choice
- List the substances: Write down which substances and mixtures are handled. The safety data sheets for these substances contain guidance on hand protection.
- Match the marking: Check whether the glove's EN ISO 374 details fit your substances. If in doubt, ask the manufacturer.
- Look at the task: Fine work calls for sensitivity, while gripping wet or oily parts calls for grip. According to the manufacturer, the GRIP model has a sanded nitrile layer on the palm and fingertips for dry and oil grip.
- Choose the size: A glove that is too large slips, one that is too small feels tight. The models are available in the size ranges shown above.
- Define the wearing time: Decide when gloves are changed, guided by the manufacturer's information.
Examples from everyday use
Laboratory and filling
When decanting and measuring, sensitivity and the right marking are what count. According to the manufacturer, the two nitrile GREEN BARRIER models are intended for chemical and laboratory work, among other uses, and at 33 cm they are slightly longer. Compare the EN ISO 374-1 letter code with the substances that are actually used.
Workshop and vehicle construction
Oily parts are often handled in the workshop, so a glove with a grippy surface can make sense. The GRIP model combines cotton tricot with a petrol-coloured full coating and a black, sanded nitrile layer. Here too, check whether the marking suits the fluids and lubricants in use.
Frequently asked questions
Is the reference to EN ISO 374 in the product name enough?
No. The name only shows that the glove is marked to this standard. To make a choice, you need the full details from the data sheet, including the type and letter code.
Why do similar models have different letters?
Each model is tested on its own. Material, construction and coating affect the result. That is why GREEN BARRIER, GREEN BARRIER FLEX and GREEN BARRIER GRIP differ in their details.
Are the gloves suitable for food?
According to the manufacturer, all three models are suitable for food contact. For your specific application, the details in the data sheet apply.
