In the production, R&D, and quality inspection of enamel products, impact resistance serves as a core indicator of product durability and reliability, directly influencing end-user experience and enterprise market competitiveness. ISO 4532:1991 (international standard) and DIN EN ISO 4532:2022 (the latest EU-adapted version) stand as authoritative specifications for enamel impact resistance testing. They clearly define the test method using a pistol-type impact tester, establishing a unified quality evaluation system for the global enamel industry.
We have developed and manufactured our enamel impact test apparatus in full compliance with ISO 4532 standard. From test principles to equipment structure, every detail precisely meets standard requirements: It adopts a spring-driven 5mm steel ball impact mechanism (spring constant 20N/cm±0.5N/cm), to simulate dynamic impact loads that enamelled articles may encounter during transportation, installation, and use. By quantifying the critical force value of the first visible damage, the pistol scientifically assesses the impact toughness of the enamel layer. Whether for kitchenware, industrial enamel reactors, or architectural enamel panels, this equipment delivers internationally standardized test data, helping enterprises meet domestic and foreign market access requirements and resolve export compliance challenges.
Technological Empowerment: Precision and Efficiency Reshape Enamel Quality Control Processes
1. Core Technical Parameters of Impact Pistol: Balancing Precision and Flexibility
- Precision Force Control: Continuously adjustable from 0 to 90N/cm, with a minimum scale increment of 2N/cm and a force accuracy error ≤±3%. It accurately captures the critical state of the enamel layer from intact to damaged, avoiding quality misjudgments caused by test errors.
- Diversified Scene Adaptability: Equipped with a dedicated triangular bracket and cross-slot structure, it ensures stable testing on uneven sample surfaces, and adapts to small-radius workpieces and edge detection—overcoming the limitations of traditional equipment in test scenarios.
- User-Friendly Portable Design: Features a mechanical structure that requires no external power supply. Lightweight and compact, it fits directly into a carrying case for mobile testing across laboratories, workshops, and factories, perfectly meeting the needs of in-process production control.
2. Standardized Test Procedures: Ensuring Data Comparability
The impact pistol strictly follows the test procedures specified in ISO 4532. In the pre-test phase, it explores the force range in 10N increments; in the precision test phase, it narrows down to the critical value in 2N steps. The distance between impact points is ≥20mm, and each sample undergoes at least 5 valid tests to ensure data repeatability and comparability. Combined with the alcohol staining method for damage identification, it clearly identifies failure modes such as crack networks, enamel fragmentation, and local peeling—providing precise data support for product formula optimization and process improvement.
