D5396-04 – Standard Test Method Technical Guide
📐 Classification of Reclaimed Perchloroethylene
ASTM D5396-04 specifies reclaimed perchloroethylene for noncritical industrial applications such as metal cleaning. It is not recommended for dry cleaning, which is covered by Specification D4081. The standard defines three types based on precision requirements:
- Type I – For precision applications.
- Type II – For less demanding precision applications.
- Type III – General-purpose technical grade.
All types must meet the identical property requirements outlined in Table 1.
⚙️ Required Properties and Testing Methods
Reclaimed perchloroethylene must comply with the properties in Table 1, determined via ASTM test methods:
- Color per Test Method D2108 (Platinum-Cobalt Scale).
- Specific Gravity per Test Methods D2111.
- Nonvolatile Matter per Test Methods D2109.
- Water Content per Test Methods D3401 or Test Method E1064.
- Acidity-Alkalinity per Test Method D2989.
- Total Acid Acceptance per Test Method D2942.
- Water-Soluble Halide Ion per Test Methods D2988.
- Appearance per Test Methods D3741.
Purity analysis can be conducted using Gas Chromatography per Practice D6806.
📊 Specification Requirements
Table 1 summarizes the mandatory specification limits for reclaimed perchloroethylene Types I, II, and III.
| 🟦 Property | 📏 Units | 📐 Requirement |
|---|---|---|
| Color | Pt-Co | ≤ 10 |
| Specific Gravity at 25/25°C | – | 1.620 – 1.625 |
| Nonvolatile Matter | ppm by mass | ≤ 10 |
| Water Content | ppm by mass | ≤ 100 |
| Acidity as HCl | ppm by mass | ≤ 5 |
| Total Acid Acceptance | mg KOH/g | ≤ 0.02 |
| Water-Soluble Halide Ion | – | Pass D2988 Test |
| Appearance | – | Clear, Free of Suspended Matter |
💡 Note: This standard is for reclaimed solvent only. For virgin perchloroethylene in dry cleaning, refer to ASTM D4081.
⚠️ Regulatory Compliance: Industrial packaging must adhere to DOT (49 CFR 100-199) and OSHA (29 CFR 1910.1200) regulations. Always check local requirements.
