Discover everything about automotive quality control, aftermarket auto product inspections, and QC standards:


The multi-billion automotive aftermarket industry, with an estimated annual value of $257B in the US alone, is responsible for keeping motor vehicles safe, environment-friendly, and reliable after they are purchased from car dealers with automotive quality control being an essential part of the process. The increasing demand for parts used in the customization, restoration, and improvement of performance of vehicles has provided the industry with new avenues for growth. In China, manufacturers are experiencing unprecedented growth because of these new trends. Countless customized rims, tires, and other aftermarket auto products are outsourced in the country annually.

ASTM C1674-11

The requirements for using catalytic converters in automotives vary for each jurisdiction, but the trend is moving towards policies promoting its use. Emission test requirements are becoming more rigorous that cars without catalytic converters would generally fail these days. Many people are also voluntarily using these environment-saving car accessories as they become more concerned with the dangers brought about by unclean air. ASTM C1674-11 specifies the test procedure for determining the flexural strength of honeycomb ceramics, the main component of modern catalytic converters. This ASTM standard is used to ensure that honeycomb ceramics in catalytic converters will remain effective and in good form after heavy and extended use.
