Horizontal and Vertical Burning TesterCleaning and Maintenance Specifications for Horizontal and Vertical Burning Tester, compiled based on standard operating guidelines and manufacturer recommendations:

I. Daily Cleaning Process

Combustion Chamber Cleaning

Immediately remove carbonized residues from the chamber after each test to avoid clogging the exhaust ducts.

Use a soft brush to clean the metal mesh and fixtures; avoid using sharp tools to scrape the stainless steel inner walls.

Gas System Maintenance

Weekly, use a needle to clear the Bunsen burner nozzle to prevent carbon buildup from affecting flame stability.

Check the gas pipeline seal (soap water test) and replace filters regularly (recommended every 3 months).

II. Periodic Maintenance

Key Component Calibration

Monthly calibration of flame height gauge (error ≤1mm) and timer accuracy (±0.1 seconds).

Quarterly inspection of thermocouple temperature sensors to ensure the heating time from 100℃ to 700℃ is 54±2 seconds.

Lubrication and Rust Prevention

Apply high-temperature grease to rails and electric sliders every six months; spray anti-rust oil on exposed metal parts.

III. Long-Term Storage Maintenance

Drain residual gas from the gas pipelines, cover with a dust cover after power-off.

Place desiccant inside the chamber to control humidity below 20%.

IV. Safety Precautions

Turn off power and gas valves during cleaning; wear safety goggles and dust masks.

Regularly inspect the exhaust system (recommended every six months) to ensure an air exchange rate of ≥20 times/hour.

Standardized maintenance can extend equipment life and ensure test data accuracy.

If possible, the test sample should be a complete product. The selection of test samples should ensure that the test conditions do not significantly differ from those in normal use, such as shape, ventilation, thermal stress effects, and the impact of flames or burning particles or hot particles from the test sample falling near the test sample.

If testing cannot be performed on a complete product, or unless otherwise specified by relevant standards, one of the following methods may be used: a) Cut a piece from the component to be tested;

b) Make a small hole in the complete product to allow contact with the glow wire; c) Remove the component to be tested from the complete product for separate testing.

The relevant standards should specify which parts can be removed to allow access to the glow wire. A hole that is too small may affect test results due to the curling of surrounding objects, a decrease in glow wire temperature, or reduced oxygen utilization. A hole that is too large may provide more oxygen than the steady state, also affecting test results Horizontal and Vertical Burning TesterCZF-C

Main Purpose: The Horizontal and Vertical Burning Tester complies with

GB/T2408-2008, UL94 V0, V1, V2; ASTM D635, IEC60695-11-3 (5VA, 5VB grade materials, flame power: 500W); IEC60695-11-4 (V-0, V-1, V-2 grade materials, HB grade); GB/T5169-16 (IEC60695-11-10) "50W Flame Test Method"; GB/T5169-17 (IEC60695-11-20) "500W Flame Test Method"; GB5169.15 and other standard requirements.

Operating and Maintenance Guide for Horizontal and Vertical Burning Tester, compiled based on standard specifications and manufacturer recommendations:

I. Standard Operating Process

Device Installation and Debugging

Connect gas (methane/propane) pipelines and check for leaks, adjust pressure reducing valve to 0.1-0.2MPa.

Install exhaust pipe (diameter 100mm) to the outdoors to ensure smooth exhaust emission.

Sample Preparation

Size is typically 125mm×13mm×3mm, requiring preconditioning at 23℃±2℃, 50% humidity for 48 hours.

For horizontal testing, clamp the sample horizontally; for vertical testing, adjust the fixture to 90° or 45° (if dripping occurs).

Flame Calibration

Use a 20mm flame scale to calibrate the Bunsen burner; flame height error must be ≤1mm (horizontal test) or 125mm (vertical test).

Test Execution

Select mode (horizontal/vertical), set flame application time (e.g., 10 seconds), start and automatically record after-flame/after-glow time.

Vertical testing requires two repeated burns; the instrument automatically completes cooling and secondary ignition.

II. Key Maintenance Measures

Daily Maintenance

Cleaning: Clean carbonized residues from the combustion chamber after testing to avoid airflow blockage.

Gas check: Daily soap water test for pipeline sealing; replace filters regularly.

Periodic Maintenance

Nozzle cleaning: Weekly use of a needle to clear the burner to prevent carbon buildup affecting flame stability.

Sensor calibration: Monthly calibration of thermocouple temperature and timer accuracy (error ±1%).

Long-Term Storage Maintenance

Drain gas pipelines, cover with dust cover after power-off, apply anti-rust oil to metal parts.

III. Safety Precautions

Do not open the chamber door during testing; must be equipped with emergency stop button and leakage protection device.

Gas purity ≥98%; impurities may cause abnormal flames or equipment damage.

Standardized operation and regular maintenance ensure test data accuracy and extend equipment life.

A hole that is too small may affect test results due to the curling of surrounding objects, a decrease in glow wire temperature, or reduced oxygen utilization. A hole that is too large may provide more oxygen than the steady state, also affecting test results.

During the test, if any part of the equipment protecting the sample ignites due to excessive heat and affects the heating conditions of the test sample, such a test should be considered invalid.

It should be ensured that during the specified test, the glow wire does not cause the component to ignite. If the component ignites, the duration of its burning is limited and will not cause the test to produce or spread flames or hot particles to the surroundings.

If ignition occurs during the application of the glow wire test, further testing may be required, such as applying a needle flame to the ignition source or repeating the glow wire test.

For small components that may cause flame spread (as in the test described in clause 5-19o).

The test device's internal network sA?f2oe xpor血aAn evaluates the possibility of flame spread from hot particles falling from the test sample. According to GB/T 5-200, place materials or components representing the surroundings below the test sample. The distance between the test sample and the representative material should equal the actual distance when the sample is installed in electrical equipment.

If testing a complete industrial device, follow the steps and use its effective code B/s160.10-200s.

The specified underlying layer should match the device's internal network fki structure. If the test sample is a complete industrial device, fix it in its normal use position according to cT su规定的铺底层Rmm-器品m处.
