ISO 6460-3:2007/Amd 2:2022

Overview

ISO 6460-3:2007/Amd 2:2022 is an important international standard published by the International Organization for Standardization (ISO) that focuses on motorcycles. Specifically, it provides an enhanced amendment to the measurement method for fuel consumption of motorcycles when operated at a constant speed. This part of the ISO 6460 series addresses the methodology used to measure fuel consumption accurately, aiming to support consistency and reliability in emissions and fuel efficiency assessments.

This amendment introduces updates to formulas and calculation procedures to refine how fuel consumption per 100 kilometers is quantified. These improvements help manufacturers, regulators, and researchers better assess environmental impacts and fuel efficiency in motorcycle testing.

Key Topics

• Measurement Methodology: Detailed procedures for measuring motorcycle fuel consumption at a steady, constant speed ensuring results are comparable and reproducible across different tests and environments.
• Updated Calculations and Formulas: Revised formulas included in Amendment 2 streamline calculations for fuel consumption denoted as F (L/100 km), improving standardization and accuracy.
• Mean Value Calculation: Incorporates a method for calculating the mean of average specific fuel consumption rounded to four significant digits, offering clarity in reporting and data presentation.
• Constant Speed Focus: Concentrates on fuel consumption measurement under constant speed conditions, which is critical for establishing baseline efficiency parameters for motorcycles.
• Technical Committee Oversight: Developed by ISO/TC 22/SC 38, this amendment benefits from expert input from motorcycle and moped specialists ensuring technical relevance and practical application.

Applications

• Regulatory Compliance: Enables manufacturers to certify motorcycles meet fuel efficiency regulations and environmental standards by using a recognized global measurement method.
• Product Development: Supports motorcycle designers and engineers during engine tuning and fuel system optimization by providing accurate fuel consumption data at fixed speeds.
• Environmental Impact Studies: Assists government agencies and environmental researchers in assessing fuel use impacts and emissions to inform policy-making and pollution control strategies.
• Standardization of Testing Protocols: Allows testing facilities and laboratories worldwide to harmonize procedures for consistent evaluation of motorcycle fuel consumption.
• Consumer Information: Helps provide reliable fuel economy data to consumers, fostering informed decision-making about motorcycle purchases with sustainability in mind.

Related Standards

• ISO 6460 Series: This amendment forms part 3 of the broader ISO 6460 standard, which covers various aspects of measuring gaseous exhaust emissions and fuel consumption in motorcycles.
• ISO/IEC Directives: The amendment follows the ISO/IEC guidelines for standard development, ensuring procedural consistency and quality of documentation.
• ISO 6460-1 & ISO 6460-2: Other parts of the series address different testing conditions and measurement methods for gaseous emissions, complementing Part 3's focus on fuel consumption.
• International Electrotechnical Commission (IEC) Collaboration: ISO closely coordinates with IEC to maintain alignment on overlapping technical issues related to vehicle standardization.
