Class 9 Talc

Class 9 Talc About

JIS Z 8901 Class 9 Talc Dust is a standardized laboratory test dust used for evaluating air filter performance, sealing system integrity, dust ingress protection, and sensor enclosure durability. Produced in accordance with Japanese Industrial Standard (JIS) Z 8901, Class 9, this dust contains ultrafine talcum powder, mimicking real-world airborne mineral particulates.Due to its fine particle size, low abrasiveness, and natural mineral stability, it is ideal for testing sensitive electronic components and IP-rated enclosures, including smartphones, automotive sensors, and HVAC filters.Scope : This Japanese Industrial Standard specifies both: the test powders which can be used for the dust separatio n test of a dust separtation test of a dust separator or an air filter, for the function test of various testers, and for wear test; and the test particles, which can be used for the calibration of light-scattering automatic particle counter, the test of particle collecting rate for super high performance air filter, and the calibration of an automatic counter of particulate materials floating in air.Test Powder Class 4 and Class 9 The quality of test powders class 4 and class 9 (Talc) shall conform to the following items.Particle Density : Particle density shall be the value of 2.7 g/cm3 to 2.9 g/cm3 when measured according to the method in test. Applications Sensor and electronics enclosure IP testing HVAC and automotive air filter efficiency Durability testing of gaskets, seals, vents Cleanroom air purification assessments Testing under dust chamber simulation (JIS, IEC, ISO) FAQsQ: What are Japanese Industrial Standard test powders used for?A: They are used in dust separation tests, air filter function tests, wear tests, and other industrial evaluations.Q: What is the specified particle density for Class 4 and Class 9 test powders?A: The particle density must be within the range of 2.7 g/cm to 2.9 g/cm, measured according to the designated method.Q: Can these test powders be used for calibrating automatic particle counters?A: Yes, these test particles are suitable for calibrating light-scattering automatic particle counters and evaluating high-performance air filters.Q: What standards do Class 4 and Class 9 powders conform to?A: They conform to Japanese Industrial Standards, ensuring accuracy and reliability for various testing applications.Q: Are there specific industries where these powders are essential?A: Yes, they are widely used in industries such as air filtration, automotive testing, environmental monitoring, and laboratory research.


Safe Storage and Handling

Always handle Class 9 Talc with care. To maintain quality and ensure safety, avoid inhaling the powder and store it in a cool, dry place with the container tightly sealed. This minimizes the risk of contamination and respiratory irritation, upholding international safety norms.


Precision for Laboratory Testing

Class 9 Talc is specifically manufactured for use as a test dust in laboratories and industrial particle testing. Its consistent particle size, purity, and compliance with the JIS Z 8901 standard make it ideal for controlled testing environments requiring reliable contaminant simulation.


Packaging and Shelf Life

Supplied in sealed plastic containers ranging from 500 g to 1 kg, the product maintains its integrity throughout its shelf life of up to two years. Proper packaging ensures safety, prevents moisture ingress, and keeps the powder uncontaminated for accurate testing results.
