prEN ISO 18889 is a CEN draft standard for protective gloves for pesticide operators and re-entry workers. It sets minimum performance, classification, and labelling requirements for gloves used to protect hands, or hands and forearms, against contact with pesticide products, and it is meant for glove makers and for people choosing PPE for pesticide work.

What does prEN ISO 18889 specify?

prEN ISO 18889 specifies how protective gloves for pesticide operators and re-entry workers are classified, tested, marked, and described to the user. It covers gloves made with elastomeric and polymeric materials in the areas that provide protection, and it is intended to be used with ISO 21420.

The document does not cover protection against fumigants. Its structure is straightforward: scope, normative references, terms and definitions, classification and testing requirements, sampling, marking, and information supplied by the manufacturer.

Annex	What it covers
Annex A	Surrogate test chemical EC-DY used for permeation testing
Annex B	Risk assessment and the role of PPE in reducing pesticide risk
Annex C	Rationale and feedback for the GR glove category
Annex D	Basis for the changes to permeation requirements in clause 4.2.2.2
Annex E	Fingertip coating requirements for GR gloves
Annex ZA	Relationship with Regulation 2016/425

What are the key requirements of prEN ISO 18889?

prEN ISO 18889 defines three glove categories - G1, G2 and GR - and ties each one to a different use case. In practice, this helps a buyer or safety officer match the glove to the task instead of treating all pesticide gloves as interchangeable.

1) The glove category must match the exposure situation

prEN ISO 18889 distinguishes between whole-hand chemical protection and partial protection for re-entry work. G1 gloves are for lower-risk situations, G2 gloves are for higher-risk work and concentrated or diluted pesticide use, and GR gloves are for certain re-entry tasks where protection is needed mainly on the palm side and fingertips.

That matters because the document does not treat a glove with good chemical resistance as automatically suitable for every pesticide task. The category determines whether the glove is acceptable for mixing, loading, application, or re-entry work.

2) Gloves must meet ISO 21420 and the clause 4 test package

prEN ISO 18889 requires all compliant gloves to meet ISO 21420, Clauses 4, 5 and 7, and then to pass the tests that apply to their category. If cleaning is claimed, the relevant performance tests are done before and after the maximum recommended cleaning cycles, and the lower result governs the rating.

That means the declaration on the glove has to reflect real use and maintenance, not only a fresh glove straight out of the package.

3) Penetration and permeation are both controlled

prEN ISO 18889 uses penetration testing for G1 and G2 gloves and permeation testing for G1, G2 and GR gloves. Penetration checks whether liquid can pass through seams, pinholes, or other imperfections, while permeation checks molecular transfer through the material itself.

For chemical resistance, the standard uses both ISO 374-1 and ISO 19918. It also uses a pesticide surrogate, EC-DY, for the cumulative permeation test, and allows additional workplace pesticides to be tested when requested. In practice, this means the glove material has to resist both physical leakage and chemical transfer.

4) G2 gloves carry the highest overall performance burden

prEN ISO 18889 sets stricter expectations for G2 gloves than for G1 gloves. G2 gloves must pass penetration testing, meet the stronger chemical resistance class, and also satisfy the minimum mechanical requirements in ISO 23388.

For users, that means G2 is the category to look for when the task involves concentrated pesticide formulations, higher exposure, or added mechanical stress during work.

5) GR gloves are partial-protection gloves for specific re-entry tasks

prEN ISO 18889 requires GR gloves to be permeation-resistant in the palm area and mechanically suitable for re-entry tasks, while keeping the back of the hand breathable. The coated area must cover the palm side and at least 30 mm of the fingertips on the back of the hand, with the same polymeric material on the palm and finger tips.

This matters because GR gloves are not a replacement for whole-hand chemical gloves. They are meant for situations where workers contact dry pesticide residues during re-entry and need a balance of protection, comfort, and dexterity.

6) Mechanical resistance is part of the glove definition

prEN ISO 18889 requires G2 and GR gloves to meet minimum mechanical performance under ISO 23388, including abrasion resistance, cut resistance, and puncture resistance, and tear resistance for GR gloves. In practical terms, this helps the glove survive tasks such as handling branches, wires, or other rough surfaces during work.

7) Marking and user information are part of compliance

prEN ISO 18889 requires the standard ISO 21420 marking plus a specific pictogram based on ISO 7000-3126, with ISO 18889 and the level - G1, G2 or GR - shown on the glove marking. The user information must also include warnings about test data not representing workplace duration, checking suitability for the task, inspecting for defects, and removing the glove after a concentrate spill.

For buyers and users, the label and instructions are not just paperwork - they are how the glove’s intended use, limitations, and cleaning or single-use status are communicated.

What terms does prEN ISO 18889 define?

prEN ISO 18889 defines the vocabulary used to classify glove performance and pesticide exposure situations.

• Active ingredient - the component of a pesticide formulation that provides the intended phytosanitarian effect.
• Decontamination - removing contaminants from a protective material so it can be used again as intended.
• Degradation - a harmful change in a material’s mechanical properties after contact with a chemical or heat.
• Penetration - chemical movement through flaws such as seams, pinholes, or porous areas on a non-molecular level.
• Permeation - chemical movement through a material on a molecular level by sorption, diffusion, and desorption.
• Pesticide operator - a person who handles pesticides, including mixing, loading, transferring, applying, cleaning, adjusting, repairing, or disposing of them.
• Re-entry worker - a person who may contact pesticides in an area that has already been treated.
• Test liquid - the liquid form of the test chemical or challenge chemical.

Who uses prEN ISO 18889?

prEN ISO 18889 is used by glove manufacturers, pesticide product manufacturers, trainers, competent authorities, and other people or organizations that decide which PPE should be used against pesticide products. It is also relevant to risk assessors who decide whether a task needs G1, G2, or GR gloves.

In practice, the standard supports product design, laboratory testing, labelling, registration dossiers, and PPE selection for agricultural and non-agricultural settings. It is especially relevant where worker exposure has to be controlled during mixing, loading, spraying, or re-entry work.

What changed in prEN ISO 18889 from the previous edition?

prEN ISO 18889 cancels and replaces ISO 18889:2019 and has been technically revised. The changes listed in the foreword are:

• normative references have been updated
• terms and definitions have been updated
• Table 1 has been revised
• subclause 4.2.2.2 has been revised
• subclause 4.2.3.2 has been revised
• subclause 5.1 has been revised
• clause 5.3 has been added
• subclauses 6.3 and 6.5 have been revised
• the annex order has been changed and additional informative annexes have been added

Which standards are used with prEN ISO 18889?

prEN ISO 18889 relies on several other standards for general glove requirements, test methods, and labelling.

Standard	What it contributes
ISO 21420	General glove requirements and test methods; it is required in conjunction with this document
ISO 374-1	Chemical risk terminology and performance requirements used for permeation classification
ISO 374-2	Penetration resistance test method
ISO 3696	Water quality for preparing test solutions
ISO 3758	Care labelling symbols when cleaning is claimed
ISO 19918	Measurement of cumulative permeation for low-vapour-pressure chemicals
ISO 23388	Mechanical risk test methods for abrasion, cut, tear, and puncture

What does the prEN ISO 18889 document contain?

prEN ISO 18889 contains the classification system, the test methods, the sampling rules, the marking format, and the manufacturer information that go with pesticide gloves. It also includes a table that compares G1, G2 and GR requirements, plus figures that show the GR coated area and the glove sampling positions.

The annexes add the technical background that supports the requirements. Annex A gives the surrogate test chemical EC-DY, Annex D explains why the permeation requirement was changed, and Annex E illustrates what counts as acceptable fingertip coating for GR gloves.

For labs and certifiers, the document is a test-and-declaration standard. For users and buyers, it is a selection and labelling standard that helps identify whether a glove is meant for whole-hand chemical protection, higher-risk pesticide work, or limited re-entry tasks.

Introduction
This document addresses the performance requirements for gloves worn by operators handling liquid
pesticide products as well as gloves worn by re-entry workers. It includes requirements for chemical
resistant gloves that provide protection to the whole hand as well as gloves used for certain re-entry
activities for which partial protection in the palm-side of the hand is sufficient.
This document classifies gloves into two categories: gloves that provide chemical protection to the whole
hand and gloves that provide protection only to the fingertips and palm-side of the hand (suitable for certain
re-entry tasks). Gloves that provide protection to the whole hand include two performance levels (G1 and
G2) and a single performance level (GR) for gloves suitable for certain re-entry tasks. A brief description of
the two categories is given below:
— Chemical resistant gloves:
Material as well as whole glove testing is required for gloves classified as G1 and G2. In addition to tests
conducted for chemical resistant gloves, these gloves are also tested with a pesticide surrogate. Since
the active ingredient of pesticides is typically a chemical with low vapour pressure and/or low solubility
in collection media, EN 16523-1:2015 cannot be used to measure permeation of active ingredient in most
pesticide products. Therefore, ISO 19918 is used to measure cumulative permeation with the pesticide
surrogate. G1 gloves provide lower level of protection than G2 gloves.
— G1 gloves are suitable when the potential risk is relatively low. These gloves are not suitable for
use with concentrated pesticide formulations and/or for scenarios where mechanical risks exist. G1
gloves are typically single use gloves.
— G2 gloves are suitable when the potential risk is higher. These gloves are suitable for use with
diluted as well as concentrated pesticides. G2 gloves also meet the minimum mechanical resistance
requirements and are therefore suitable for activities that require gloves with minimum mechanical
strength.
— Gloves with partial chemical protection:
GR gloves provide protection only to the palm-side of the hand for a re-entry worker who is in contact
with dry pesticide residues that remain on the plant surface after pesticide application. This glove
category is suitable only for re-entry activities where it has been determined that protection provided
to the fingertips and palm-side of the hand is sufficient. They cannot be used in place of G1 and G2 gloves
that protect the whole hand. GR gloves also have mechanical properties that are required for several re-
entry tasks. Breathable material in the back of the hand provides comfort. To get more information on
why GR gloves are proposed, see Annex C.
Registration of pesticide products, such as insecticides, herbicides, and fungicides, involves the assessment
of operator and re-entry worker exposures and risks, which determines the need for PPE (including gloves)
required for risk mitigation. See Annex B for information on risk assessment and use of PPE (including
gloves) for risk mitigation. Protection should correspond to the identified risks in order to avoid a loss of
comfort due to overprotection. Actual field trials are used to determine the operator risk while handling
concentrates during mixing/loading, and applying diluted pesticides under different scenarios, as well as
risks to re-entry workers exposed to dry, partially dry and wet residues. Since protective clothing can be
contaminated in various ways, laboratory test methods used in the document rate materials and gloves
rather than simulate the various field conditions. Laboratory tests are often accelerated tests and therefore
laboratory data cannot be used for direct comparison with field data.
This document is intended for glove manufacturers, pesticide product manufacturers as well as trainers,
competent authorities, and other individuals or organizations that make decisions regarding PPE for
protection against pesticide products.

4 Classification and testing requirements
4.1 General
All gloves complying with this document shall fulfil the requirements of ISO 21420, Clauses 4, 5 and 7. In
addition, each type of glove shall be tested and classified by level of performance in accordance with the
requirements as stated in Clause 4.
If not otherwise specified, all tests shall be performed on unused gloves. If cleaning instructions are provided
(see 7.e), the relevant performance-related tests shall be performed on the gloves, before and after they
have been subjected to the maximum recommended number of cleaning cycles using the claimed cleaning
instructions. The level of performance is given by the lowest results obtained before and after cleaning.
G1 gloves shall pass the penetration test and demonstrate a minimum level of liquid permeation resistance.
G1 gloves are not suitable for use with concentrated pesticide formulations and/or for scenarios where
mechanical risks exist.
G2 gloves shall pass the penetration test, and the glove material shall meet the liquid permeation
requirements. G2 glove is suitable for use with concentrated as well as diluted pesticide formulations and
for activities where mechanical risk exists.
GR gloves shall meet the permeation requirements in the palm area as well as mechanical requirements. GR
gloves are not suitable for use by pesticide operators or for re-entry tasks where the pesticide may touch the
uncoated back of the glove.
Table 1 provides a summary of the tests to be conducted for gloves for pesticide operators and re-entry
workers. The stringency in the testing requirements to determine protection is higher for G2 gloves.
Therefore, any G2 glove necessarily meets G1 requirements.
To be classified in either G1 or G2 or GR, all the applicable requirements shall be satisfied.

4.2 Performance requirements
4.2.1 Penetration
For gloves G1 and G2, tests shall be performed on three gloves to measure glove integrity in accordance with
ISO 374-2.
All three gloves shall pass both tests. Gloves tested with air can then be used to conduct tests with water.
4.2.2 Permeation
4.2.2.1 Glove materials for G1, G2, and GR shall be conditioned and breakthrough time measured in
accordance with ISO 374-1.
Glove materials for G1 shall comply with at least the requirement for Type C.
Glove materials for G2 shall comply with at least the requirement for Type B.
NOTE 1 The test is needed to ensure that G1 and G2 gloves have a minimum resistance to chemicals before assessing
it for protection against pesticides.
GR glove materials shall be tested with test chemical K. GR gloves shall comply with at least the minimum
requirement of Performance Level 2 (breakthrough time of 30 min) when tested with chemical K.
NOTE 2 Test chemical K (40 % sodium hydroxide) was selected for testing as it is a commonly used water-based
test chemical that can differentiate between the different types of glove coating. Test to be done before assessing the
material for protection against pesticides.
4.2.2.2 Glove materials for G1, G2 and GR shall be conditioned and cumulative permeation measured in
accordance with ISO 19918. Pesticide surrogate EC-DY (concentrate with 10 % disperse yellow dye) shall be
used as the test chemical. Composition and other information for the test chemical is included in Annex A.
When requested, other pesticides representing the workplace can be added. For additional testing the
procedure, test methods, and pass criteria shall be the same as that for pesticide surrogate EC-DY. The test
chemical shall be the specific pesticide formulation, either concentrated or diluted with water in accordance
with the manufacturer's instructions.
NOTE 1 Pesticide formulations are mixtures that, when diluted in water, are often emulsions or suspensions.
During the test, agitation in the challenge test cell can be necessary. Selective detection systems can be required to
detect the active ingredient.
For G1, G2 and GR glove materials, tests shall be conducted with a diluted formulation for one hour. Water
grade 3 (according to ISO 3696) or deionized water shall be used to prepare the diluted solution with 2,5 %
EC-DY.
NOTE 2 To prepare 100 ml of diluted test chemical, 2,5 ml of EC-DY is made up to 100 ml (0,25 % disperse yellow 26
dye).
NOTE 3 The duration of the test is not based on actual use time since the permeation test is an accelerated test in
which the surface of the specimen is in constant contact with the test chemical. Although the duration of the exposure
can be for a longer period during field application with the dilute formulation, the entire surface is not in constant
contact with the test chemical. In case of accidental spills, the operator needs to remove the glove immediately, and
therefore the contact time with the concentrate is much shorter.
For G1, G2 and GR, specimens for testing shall be taken in accordance with clause 5.1. For all gloves, the
maximum cumulative permeation shall be 10,0 µg/cm2 disperse yellow 26 dye for all specimens when
tested against the diluted surrogate EC-DY.
NOTE 4 An accelerated laboratory test is used to classify materials. The maximum limits are not appropriate for
use in calculating default protection factors used for exposure mitigation in operator exposure and risk assessment.

4.2.3 Glove design requirement
For safety reasons, the gloves shall have minimum design requirements.
4.2.3.1 Minimum length shall be 240 mm for G1 and 290 mm for G2 gloves. For G1 gloves with length
between 240 mm and 290 mm, a statement in accordance with Clause 7 k) shall be required.
NOTE An overlap of approximately 50 mm between the glove and the garment is included to prevent the possibility
of pesticides penetrating between the garment sleeve and the glove [see Clause 7 k)]
4.2.3.2 GR gloves shall have at least the palm-side of the hand and ≥30 mm of the fingertips on the back of
the hand coated (see Figure 1). The polymeric coating must be made of the same material on the palm and
on the tips of all fingers. This coating must completely cover the fingertips, without any gaps, and extend
towards the inner side of the fingers by at least 30 mm, measured in a straight line from the distal end of
each finger. Annex E shows examples of GR gloves that represent different fingertip coating.

5 Sampling
5.1 Sampling for permeation
Three test specimens shall be taken from the palm area of three gloves. For G1 and G2, if the back composition
is different from the palm composition, three additional specimens shall be taken from the back of three
gloves.
For G1 and G2, If the glove is longer or equal to 400 mm, three additional test specimens from three gloves
shall be taken with the center being at 80 mm from the end of the cuff (see Figure 2).
