Standard explainer · EN ISO 27065
Most farm spraying happens in clothing chosen by habit, yet there's a dedicated standard for exactly this job: EN ISO 27065 grades operator clothing C1 to C3 against pesticide handling's real exposures. It's the missing link between 'old waterproofs' and full chemical suits — and the product label is what invokes it.
The system
EN ISO 27065 certifies clothing specifically against liquid pesticide exposure — penetration and repellency of spray formulations rather than the industrial-chemical batteries of the EN 13034 world. C1 covers lower-exposure operation (cab work, incidental drift), C2 the standard operator level for mixing, loading and application, and C3 the highest exposures — handling concentrates, drenched conditions, knapsack work in crops. The garments are washable and re-certifiable through their stated care cycle, which is the standard's quiet advantage: purpose-made spray clothing that returns to service, versus the disposable-coverall habit that works but generates a bin-bag per tank mix.
What invokes it is the product label and safety data sheet — UK authorisation increasingly references 27065 levels for operator clothing, alongside the gauntlets, face protection and boots the label lists. The buying rule stays the one from our farm-worker guide: read the label of the product you're actually spraying; it names the level.
The levels
| Level | Exposure | Typical work |
|---|---|---|
| C1 | Low — drift and incidental contact | Cab-based application, re-entry tasks |
| C2 | Standard operator exposure | Mixing, loading, boom spraying — the working default |
| C3 | High — concentrates and wet contact | Knapsack in crop, drenching, handling neat product |
| + Gloves & face | Per product label | Nitrile gauntlets and visors ride alongside every level |
| Alternative | Type 4/6 disposables | Legitimate where the label allows — cost per season decides |
The realities
Questions
Clothing certified specifically for pesticide operators — tested against spray-formulation penetration at three levels: C1 (low exposure), C2 (standard mixing and application) and C3 (high exposure like concentrates and knapsack work). It's washable, re-usable spray kit; the pesticide product's label indicates the level required.
Often yes — Type 4/6 disposables with the right chemical performance are a legitimate alternative where the product label allows, and they suit occasional spraying. Regular operators usually land on certified 27065 garments for comfort and cost-per-season, with disposables kept for the filthiest tasks.
The label and safety data sheet specify it per product — typically protective clothing (increasingly by 27065 level), nitrile gauntlets, face or eye protection and suitable boots, with extra RPE for some formulations. The label is a legal instruction, not a suggestion; certification for the operator comes via the spray-qualification system.
