D3440-13 – Standard Test Method Technical Guide
📜 Scope and Classification
The ASTM D3440-13 (Reapproved 2019) guide provides essential guidance for preparing specifications for water-emulsion floor polishes applicable to all nonwood floors and sealed wood floors. The standard specifies that inch-pound units are the standard, with SI conversions provided for context. It also underscores the responsibility of the user to address safety and regulatory considerations.
The classification section identifies two distinct types of floor polishes:
- Buffing-Type Floor Polish: A polish that necessitates buffing to achieve or enhance its appearance.
- Self-Polishing-Type Floor Polish: A polish that dries to a shine without any buffing requirement.
🔬 Referenced Standards and Terminology
This guide references a suite of ASTM standards crucial for evaluating water-emulsion floor polishes. Terminology is standardized per ASTM D2825, where a specification is defined as a set of precise requirements with numerical limits for conformance. The referenced documents cover various test methods for properties such as gloss, friction, removability, and water spotting, providing a comprehensive toolkit for specification development.
| 🟦 Standard | 📏 Description | 📐 Purpose |
|---|---|---|
| D1455 | Test Method for 60° Specular Gloss | Measure gloss of floor polish films |
| D2047 | Test Method for Static Coefficient of Friction | Assess slip resistance using James Machine |
| D1792 | Test Method for Long-Term Removability Properties | Evaluate removability of polish films |
| D1793 | Test Method for Water Spotting | Determine resistance to water damage |
| D2048 | Test Method for Powdering of Floor Polish Films | Check for powdering or flaking |
💡 Tip: Always ensure that the reference material used for comparison is stable and representative of desired performance characteristics. It should be mutually agreed upon by the purchaser and seller to maintain consistency in evaluations.
📊 Specification Criteria and Performance Tests
The basis of purchase relies on a reference material, which is a floor polish with known characteristics. Specifications must include thresholds for various performance attributes tested per the referenced methods. Key properties include gloss (D1455), friction (D2047), removability (D1792), water residue (D1793), and soil resistance (D3206). The specification should state numeric requirements with limits to ensure conformance.
The guide also emphasizes that specifications should be documented clearly, with reference to specific test conditions. For example, the 60° gloss measurement is a common standard for evaluating polish appearance. The selection of tests depends on the intended use and classification of the polish.
⚠️ Attention: The standard advises users to determine the applicability of regulatory limitations before use. Safety, health, and environmental practices must be established as per Section 1.3.
❓ Frequently Asked Questions
🔍 What is the scope of ASTM D3440-13?
The guide covers preparing specifications for water-emulsion floor polishes used on nonwood floors and sealed wood floors, with inch-pound units as standard.
💡 How is reference material utilized in specifications?
A reference material, agreed between purchaser and seller, serves as a benchmark for comparing performance characteristics of other floor polishes.
⚡ What are the main classification types of floor polishes?
The two types are buffing-type, which requires buffing for appearance, and self-polishing-type, which dries to a shine without buffing.
📌 Which test method addresses slip resistance in floor polishes?
ASTM D2047 specifies the test method for measuring the static coefficient of friction of polish-coated flooring surfaces using the James Machine.
