🛠️ Apparatus and Materials Specification
ASTM D2377 requires a specific set of tooling to ensure a uniform specimen and repeatable results. The table below outlines the critical dimensions for the apparatus as specified in Section 4 of the standard.
| 🟦 Component | 📐 Description | ⚡ Inch-Pound | 📏 SI Equivalent |
|---|---|---|---|
| Brass Sheet | Contact weight | 3/4 × 1 1/2 in., ~1/4 in. thick | 19 × 38 mm, ~6.4 mm thick |
| Template | Steel or brass | Inside: 1 × 3 3/4 in. Outside: 2 × 4 3/4 in. Thickness: 1/8 in. |
Inside: 25.4 × 95.1 mm Outside: 51 × 121 mm Thickness: 3.2 mm |
| Steel Sheets | Tin-plated substrate | ~3 × 5 in. | ~76 × 127 mm |
| Plastic Strips | Clear LDPE film | 1 × 5 in. × 0.004 ± 0.001 in. | 25.4 × 127 mm × 0.1016 ± 0.0254 mm |
| Spatula | Narrow blade | 4 to 5 in. blade | 102 to 127 mm |
💡 Cleaning Requirement: Methyl Ethyl Ketone, Ethylene Dichloride, or a similar solvent must be used to thoroughly clean the template and steel sheets before specimen preparation to avoid contamination that could alter the tack-free time results.
🧪 Specimen Preparation and Standard Conditions
The sample must be conditioned in its original closed container for at least 5 hours at Standard Conditions as defined in Terminology C717. The sealant should be taken from a previously unopened container and thoroughly mixed prior to use.
