Frequently Asked Questions (FAQ): Salt Spray Chambers​

---

Q1: What industries rely on salt spray testing?
A: Salt spray chambers are essential for industries requiring corrosion resistance validation, including:

• ​Automotive: Testing coatings on brake components, fasteners, and chassis parts.
• ​Aerospace: Evaluating protective layers on aluminum alloys and turbine components.
• ​Electronics: Assessing connectors, PCBs, and enclosures for marine or coastal environments.
• ​Construction: Validating galvanized steel, paints, and coatings for bridges or offshore structures.

---

Q2: Which testing standards do your chambers comply with?​
A: Our chambers meet ​ASTM B117, ​ISO 9227, ​JIS Z 2371, and ​MIL-STD-810G​ standards. Customizable settings are available for specialized protocols like CCT (Cyclic Corrosion Testing) or ASTM G85.

---

Q3: How long does a typical salt spray test take?​
A: Test duration varies by material and standard:

• ​Basic neutral salt spray (NSS): 24–1,000+ hours.
• ​Acetic acid salt spray (AASS): 96–500 hours.
• ​Cyclic tests: Multi-phase cycles (spray, humidity, drying) spanning weeks.

---

Q4: What salt concentration and pH levels are maintained?​
A: Our systems use a ​5% NaCl solution​ (pH 6.5–7.2) for NSS tests. For AASS or CASS (copper-accelerated tests), pH is adjusted to 3.1–3.3 with acetic acid. Real-time sensors ensure ±0.1 pH stability.

---

Q5: How is fog settlement uniformity ensured?
A: Chambers feature:

• ​Dual-nozzle atomizers​ for consistent fog distribution.
• ​V-shaped chamber ceilings​ to prevent droplet condensation on samples.
• ​Automatic solution replenishment​ to maintain concentration accuracy.

---

Q6: What materials are compatible with salt spray testing?​
A: The chamber’s interior is built with ​316L stainless steel​ and ​PP/PTFE liners​ to resist acidic/corrosive environments. Avoid testing highly reactive materials like magnesium alloys without consulting our team.

---

Q7: How often should the chamber be cleaned and calibrated?
A:

• ​Daily: Drain residual solution and clean nozzles.
• ​Monthly: Inspect seals and replace air filters.
• ​Annually: Full calibration (temperature, spray rate, pH sensors) per ISO/IEC 17025 guidelines.

---

Q8: What safety features are included?
A:

• ​Leak detection: Alerts for solution overflow or air pressure drops.
• ​Corrosion-resistant electricals: Sealed components to prevent short circuits.
• ​Emergency stop: Instantly halts testing in case of malfunctions.

---

Q9: How do I interpret salt spray test results?
A: Post-test analysis includes:

• ​Visual inspection: Rust grading per ASTM D610.
• ​Weight loss measurement: Calculates corrosion rate (g/m²/hour).
• ​Cross-cut adhesion tests: Assess coating integrity per ISO 2409.
