Product Overview
The structural sealant compatibility test chamber is used to evaluate the compatibility of structural assembly system components—such as weatherstripping, spacers, gaskets, and fixing blocks—with sealants, as well as to determine the test methods and criteria for assessing such compatibility. It is suitable for material selection in architectural curtain wall systems. Changes in adhesion and color after testing are critical indicators for evaluating material compatibility; experience has shown that components that lose adhesion or discolor during testing will exhibit similar behavior in actual service.
This test chamber complies with the requirements specified in GB 16776-2005, “Silicone Structural Sealant for Building Applications.”

Frequently Asked Questions
Is the universal materials testing machine experiencing loading stalling or abnormal zeroing of load data?
1. Loading lag: Clean the lead screw and guide rails, apply lubricant, and remove debris from the transmission components. 2. Zeroing anomaly: Restart the equipment system, calibrate the load and displacement zero points, and check for poor electrical contact in the sensor wiring. 3. Overloading is strictly prohibited; before testing, verify that the grips are securely tightened to prevent eccentric loading of the specimen.
How often should in‑instrument verification be performed? Which instruments are required to undergo it?
High‑precision, high‑frequency‑use, and drift‑prone equipment (such as balances, penetration testers, water permeability testers, and sensor‑type devices) shall undergo intermediate verification every three months; routine equipment shall be verified every six months. Equipment that is within the verification/calibration interval, has been repaired following a malfunction, or has been relocated must undergo additional intermediate verification, with complete verification records maintained.
Is the repeatability of pendulum-type pavement friction coefficient measurements poor?
Key points for resolution: Prior to testing, thoroughly clean the pavement at each measurement point, ensuring there is no standing water, dust, or debris; calibrate the instrument’s level and zero point to ensure a standardized pendulum‑drop trajectory; strictly control the pendulum’s sliding distance; avoid conditions such as strong winds, wet pavement, or abrupt temperature changes; and calculate the average of multiple measurements taken at the same point.
How should one handle cases where the pavement infiltration meter data exceeds allowable error limits, exhibits leakage, or shows abnormal readings?
1. Sealing leaks: Inspect the base seal for aging or damage and replace it promptly; before testing, firmly press down on the base to expel any residual air inside. 2. Data deviation > ±2%: Calibrate the level sensor, clean any fouling from the graduated cylinder, and check for damage to the scale markings. 3. Compliance with new regulations: For seepage rates ≤ 300 mL/min, existing equipment may continue to be used; for rates > 300 mL/min, the accuracy of older equipment fails to meet standards, and such equipment must not be used.
Can the old Marshall compaction apparatus and stability tester still be used?
According to the 2025 revised asphalt testing procedures, after adjusting the indenter configuration on the Marshall stability test apparatus, existing instruments currently in use may continue to be operated normally without mandatory replacement; only periodic calibration to maintain accuracy and ensure equipment integrity is required.
What are the causes of uneven compaction and layered cracking in molded specimens during compaction testing?
Main causes: non‑vertical drop of the compaction hammer, rail jamming, excessive deviation in hammer weight, uneven layer thickness during loading, insufficient number of blows, or overload. Solutions: regularly lubricate the guide rails; verify and correct the vertical alignment of the hammer; strictly follow the procedure for layered material placement and step‑by‑step compaction; ensure that hammer weight and drop height comply with standards; and prevent over‑thick layers.
