D6253-24 – Standard Test Method Technical Guide
ASTM D6253 – 24, Standard Practice for Treatment and/or Marking of Wood Packaging Materials, serves as a comprehensive framework for the phytosanitary treatment, marking, and identification of wood packaging materials (WPM). This practice ensures compliance with industry, government, and international recognized standards, facilitating global trade and asset tracking.
🧱 Scope and Application of D6253–24
This practice covers the development of recommended treatment, or marking practices, or both, for WPM. It aids in identifying WPM as to phytosanitary treatment, intended service cycles, repair, the specific specification used to manufacture or recycle, and other user designated characteristics. The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This international standard was developed in accordance with internationally recognized principles on standardization established by the WTO TBT Committee.
🔥 Treatment Parameters and Key Terminology
A core technical requirement of this standard is the definition of heat treatment parameters. The standard defines Dielectric Heat Treatment (DH) as the heating of WPM using dielectric heating in accordance with a specific time-temperature schedule. The mandatory requirement is achieving a minimum wood core temperature of 60 °C for a minimum of 1 continuous minute. Verification of compliance is performed by a qualified independent certifying or inspection agency. General definitions for the packaging and distribution environments are found in Terminology D996.
| 🟦 Parameter | 📐 Requirement / Specification |
|---|---|
| Treatment Type | Dielectric Heat Treatment (DH) |
| Critical Temperature Threshold | Minimum 60 °C (140 °F) at the wood core |
| Minimum Duration at Temperature | 1 continuous minute |
| Compliance Verification | Qualified independent certifying or inspection agency |
💡 Technical Note: Achieving and verifying the 60 °C core temperature for 1 minute is critical for meeting phytosanitary regulations such as ISPM 15. Calibration of temperature probes is essential for audit compliance.
✍️ Marking Practices and Referenced Specifications
Marking according to D6253–24 identifies the WPM’s phytosanitary treatment, intended service cycles, and the specific specification governing its manufacture or recycling. The standard references key specifications for various WPM types, allowing users to clearly identify the requirements for construction and performance. Proper marking supports international shipping compliance and promotes the recycling and repair of wood packaging.

❓ Frequently Asked Questions
🔍 What is the primary scope of D6253–24?
This practice covers the development of recommended treatment, marking practices, or both, for wood packaging materials. It specifically aids in identifying WPM as to phytosanitary treatment, intended service cycles, repair, and the specific specification used to manufacture or recycle.
💡 What are the exact parameters for Dielectric Heat Treatment (DH)?
The standard mandates that the wood core must reach a minimum temperature of 60 °C and maintain this temperature for a minimum of 1 continuous minute. This is the critical threshold for phytosanitary efficacy.
⚡ How does this standard interact with international regulations like ISPM 15?
D6253–24 is designed to align with international frameworks. It identifies WPM treated or marked in accordance with industry, government, or international recognized standards, including the International Standards for Phytosanitary Measures (ISPM) Publication No. 15.
📌 Which units are considered standard under this practice?
The values stated in inch-pound units are to be regarded as the standard. The SI unit values provided in parentheses are mathematical conversions for informational purposes only and are not considered standard.
