D5022-07 – Standard Test Method Technical Guide
ASTM D5022-07 provides specifications for the identification of small-volume containers of drugs intended to be diluted before parenteral administration. The standard addresses container shape, labeling, vial closures, and ampoule markings to ensure safe handling and prevent accidental misuse.
📦 Container Design and Labeling Requirements
Per the standard, containers for concentrated drugs must not resemble normal syringes to preclude direct intravenous line injection. Labels on vials and ampoules must include the warning “Dilute Before Use” or similar, with initial capitals at least 2.5 mm in vertical height (10 point or larger) in bold font in contrasting ink. When space permits, a red box (Pantone 805 or Warm Red) should be used. If label space is insufficient, the warning size must be at least equal to the drug name and strength designation.
| 📋 Requirement | 🔧 Specification |
|---|---|
| Warning Text | “Dilute Before Use” or similar |
| Font Size | ≥ 2.5 mm vertical height (10 point or larger) |
| Font Style | Bold with initial capitals |
| Ink Color | Contrasting, preferably red box (Pantone 805 or Warm Red) |
| Space Exception | If limited, warning size must match drug name size |
⚠️ Important: The container design must prevent direct IV injection of concentrated solutions to avoid severe patient harm. Always verify the warning label before administration.
🔒 Specific Requirements for Potassium Chloride
For Potassium Chloride for Injection Concentrate, additional USP-mandated requirements apply. The label must immediately follow the drug name with a boxed warning. Vials require a black metal closure with a black cap, both marked with “Must be diluted” in legible, contrasting type. Ampoules must feature a black band or series of black bands above the constriction. These black closures and bands are exclusive to Potassium Chloride for Injection Concentrate to ensure immediate identification.
| 🟦 Component | 📐 Specification |
|---|---|
| Vial Closure | Black metal closure with black cap |
| Vial Cap Text | “Must be diluted” in legible, contrasting type |
| Ampoule Marking | Black band or series above constriction |
| Exclusivity | Only for Potassium Chloride for Injection Concentrate |
🔑 Key Tip: The black closures and bands serve as a visual cue for high-risk concentrated electrolytes, helping to prevent administration errors in clinical settings.
❓ Frequently Asked Questions
🔍 What is the minimum font size for the “Dilute Before Use” warning?
The warning must be at least 2.5 mm in vertical height, which is equivalent to 10 point or larger, in bold font with initial capitals.
💡 Why must containers not resemble syringes?
To prevent accidental direct intravenous injection of the concentrated solution, which could be harmful. The design must preclude direct IV line injection.
⚡ What distinguishes Potassium Chloride containers?
Vials must have black metal closures with black caps labeled “Must be diluted”, and ampoules must have black bands above the constriction. These features are exclusive to Potassium Chloride for Injection Concentrate.
📌 Are there exceptions for small containers with limited label space?
Yes, if space is insufficient for 10 point type, the warning must be at least equal in size to the drug name and strength designation.
