D5658-20 – Standard Test Method Technical Guide
The ASTM D5658-20 standard provides methodological guidance for collecting waste samples from trucks. It focuses on unconsolidated solid wastes in bulk loads, utilizing various sampling equipment such as scoops, triers, and augers. This practice is integral to waste management industries for verifying waste profiles and ensuring safe handling.
🚚 Overview and Scope
This practice covers several methods for collecting waste samples from trucks, adapted specifically for unconsolidated solid wastes in bulk loads using several types of sampling equipment. It is intended for use in the waste management industries to collect samples of unconsolidated waste from trucks. The purpose often is to verify with screening analyses that the waste contained in the truck is the same or similar material from a waste source that has been previously characterized and approved for treatment or disposal.
🛠️ Sampling Equipment and Procedures
The sampling procedure begins with inspecting the truck and its contents. After selecting appropriate sampling equipment, a clean device is used to scoop, core, or auger into the waste material. The sample or samples are collected and transferred to a sample container. The sampling device is then cleaned and decontaminated or disposed of, as per standard practices.
| 🟦 Method | 📏 Equipment | 📐 Description |
|---|---|---|
| Scooping | Scoop | Manual collection from accessible waste surfaces |
| Coring | Trier Sampler | Penetration to obtain vertical waste profile from depth |
| Augering | Auger | Drilling into compacted waste for deeper sampling |
⚠️ Safety and Quality Assurance
Safety precautions are paramount. The work plan must include a Worker Health and Safety section, addressing hazards associated with trucks and their potentially hazardous contents. Quality assurance and quality control planning, as per D5283, ensure data reliability. Decontamination of field equipment is guided by D5088.
Always use clean, decontaminated equipment for each sample to avoid cross-contamination as outlined in D5088.
Users must determine applicability of regulatory limitations prior to use, as per Section 1.2 of the standard.
❓ Frequently Asked Questions
🔍 What is the primary purpose of sampling waste from trucks? The purpose is to verify that the waste is the same or similar material from a waste source that has been previously characterized and approved for treatment or disposal.
💡 How is sampling equipment selected? Equipment selection depends on waste consistency, accessibility, and safety considerations, such as using a trier for coring or an auger for compacted waste.
⚡ What safety precautions are specified? The work plan must include a Worker Health and Safety section due to potential hazards from trucks and their hazardous contents.
📌 How should samples be handled after collection? Samples should be transferred to appropriate containers, labeled, and transported for analysis while maintaining chain of custody.
