ASTM D1455-17(2023) PDF

Overview

ASTM D1455-17(2023), titled Standard Test Method for 60° Specular Gloss of Emulsion Floor Polish, is an internationally recognized standard developed by ASTM International. This standard specifies the method for determining the 60° specular gloss of dried films of emulsion floor polishes after application to a substrate. By measuring the light reflected at a 60° angle from the surface, it evaluates the glossiness of emulsion floor polishes. Specular gloss is a critical appearance attribute, influencing perceptions of cleanliness and maintenance in commercial and residential flooring.

This standard is particularly useful for manufacturers, quality control laboratories, and end-users who need to compare gloss differences between floor polish products. Compliance with ASTM D1455-17(2023) helps ensure consistent, reliable results across the industry.

Key Topics

• Specular Gloss Measurement The standard describes how to measure the specular gloss of floor polish films using a glossmeter at a 60° incident angle. It helps identify differences in gloss between products.

• Applicability and Limitations While effective for most emulsion floor polishes, this method may not clearly differentiate between extremely high or low gloss finishes. In such cases, an alternative 20° angle measurement (following ASTM D523) can provide better detail.

• Test Apparatus and Substrates

  • Glossmeter: Must comply with ASTM D523 requirements, set for 60° reflection.
  • Floor Polish Applicator: As prescribed by ASTM D1436.
  • Substrates: Black glass (for most applications except hazy films) or official vinyl composition tiles (OVCT).

• Reporting Requirements Detailed reporting is mandated, including:

  • Average gloss readings at 60° (and 20°, if used)
  • Substrate types
  • Application method and number of coats
  • Instrument make/model and reference standards

• Precision, Bias, and Safety

  • Results should be repeatable within 2.5% on the same instrument (with black glass substrates).
  • Users must establish their own appropriate safety, health, and environmental practices before conducting tests.

Applications

ASTM D1455-17(2023) is essential in various practical scenarios:

• Floor Polish Manufacturing Manufacturers use this standard in R&D and quality control to ensure consistent gloss levels across batches and to benchmark new formulations.

• Comparative Product Testing Distributors and commercial procurement teams apply the method to compare different products for selection and specification purposes.

• Facility Maintenance Evaluation Building managers and cleaning service providers use gloss measurements to assess floor maintenance regimes and verify polish performance after application.

• Compliance and Certification Ensures alignment with industry best practices, contributing to acceptance in regulatory or contractually mandated testing protocols.

Related Standards
