E-TEST DUST (for the electrotechnical products)

Summary

E-Test Dusts are the test dusts for the environmental tests of the electrotechnical products.
APPIE is preparing and distributing E-Test Dusts which are prepared in accordance with the manufacture standard of APPIE based on IEC 60068-2-68.

Size distribution

APPIE and IEC measure the particle size by using of other method mutually.
Therefore,the particle size distribution provided by APPIE and IEC are similar,but not same.

Regarding order restrictions for glass beads GBM and GBL
Dear Customers

Due to the difficulty of securing inventory of the following JIS test powder glass beads GBM and GBL, shipments are currently restricted.

GBM-20 GBM-30 GBM-40
GBL-30 GBL-40 GBL-60 GBL-100

Currently, we limit the shipment of glass beads to 100g x 1 piece per one item per order.
(GBM-20 is 50g x 1 piece)

However,It is possible to order multiple different varieties with one order.
(For example, order 50g x 1 piece of GBM-20, 100g x 1 piece of GBM-30, 100g x 1 piece of GBL-60 at one time)

We apologize for the inconvenience, and thank you for your understanding.
