Product Overview
The IEC60068-2-75 Test Ehc Vertical Hammer Impact Test Machine (Model: ZLT-SZ1) is a professional testing instrument developed by ZLTJC to evaluate the impact resistance of materials and components. It strictly follows the IEC 60068-2-75 Test Ehc standard, simulating vertical free-fall impacts by a striking element to assess how specimens withstand sudden mechanical stress. This device is critical for ensuring product safety and durability in industries where impact resistance is a key performance indicator, such as electronics, home appliances, and industrial equipment manufacturing.
With a minimum order quantity (MOQ) of 1 unit, the ZLT-SZ1 caters to both small-scale labs and large production facilities. It is manufactured in China and shipped from Guangzhou Port, with a lead time of 20 days to ensure quick integration into testing workflows. Payment is processed via T/T (Telegraphic Transfer), a secure and widely accepted method for international trade.

Product Features
Precision & Compliance
±1% Fall Height Accuracy: The fall height is calibrated to ±1% precision, ensuring each impact delivers the exact energy specified by the IEC 60068-2-75 standard. This eliminates deviations that could compromise test validity.
Non-Interfering Guideway: The tube-style guideway only guides the striking element during free fall and does not rest on the specimen. At the moment of impact, the striking element is fully detached from the guideway, guaranteeing pure gravitational force.
Standardized Striking Elements: The included striking element matches the equivalent mass required for each energy level (e.g., 0.25 kg for low-energy tests, 10 kg for 50 J high-energy tests), ensuring full compliance with the standard.
User-Friendly Operation
Intuitive Height Setup: The integrated fall height scale allows operators to quickly set the required height without additional tools, reducing test preparation time.
Simple Specimen Placement: Specimens are placed on a stable horizontal platform, and the striking element is released via a straightforward mechanism, minimizing operator training requirements.
Application
Target Industries & Scenarios
Electronics Manufacturing: Testing printed circuit boards (PCBs), semiconductor casings, and electronic component housings to ensure they withstand accidental drops during production or transportation.
Home Appliance Sector: Evaluating the durability of plastic or metal casings for refrigerators, washing machines, and small kitchen appliances (e.g., blenders), which may encounter minor impacts during handling.
Industrial Equipment: Assessing control panel doors, sensor housings, and mechanical parts used in factories, where impact resistance prevents operational downtime from component failure.
Quality Control Labs: Serving as a standard tool for third-party labs and certification bodies to verify product compliance with international IEC standards before market launch.
FAQ
What standards does the ZLT-SZ1 follow?
The ZLT-SZ1 is fully compliant with IEC 60068-2-75 Test Ehc, the global standard for vertical hammer impact testing. Its results are recognized by regulatory bodies and industry partners worldwide.
Can I test different energy levels with one machine?
Yes. The ZLT-SZ1 supports all energy levels from 0.2 J to 50 J (as listed in the technical parameters). Additional striking elements (for different equivalent masses) can be purchased separately to cover all energy ranges.
How long does it take to receive the ZLT-SZ1 after ordering?
The lead time for the ZLT-SZ1 is 20 days from order confirmation. This includes manufacturing, calibration, and pre-shipment inspection to ensure quality.
Is a specimen holder included?
The standard outfit does not include a specimen holder, but ZLTJC offers customizable holders (for small components, large casings, etc.) as optional accessories. Specify your specimen size when ordering for a tailored solution.
How often should the machine be calibrated?
We recommend annual recalibration to maintain ±1% fall height accuracy. ZLTJC provides a calibration certificate with each unit and offers professional recalibration services upon request.
