Product Description

ASTM D2863 Digital Minimum Oxygen Concentration Display Oxygen Index Tester Measurement

 Introduction:-

ZY6155A Oxygen Index Tester type of product sample combustion process of polymer is just the in needed to developed according to the technical oxygen index tester is a new requirement of The instrument is used to measure the volume national standard GB / T2406.2 percentage of combustion. The oxygen index value of the polymer oxygen needed in the lowest oxygen concentration (also called oxygen index) is needed the maintain the combustion time of 180 s or the mixture of oxygen and nitrogen 50 mm long after ignition.

Frequently Asked Questions:-

What is the difference between ASTM and ISO?

ASTM is a part of ISO 45892 organizations. ISO is an organization that has representations as a national organization international from all countries including ASTM.

What is ISO 4589-2?

It specifies methods volume for determining conditions combustion support of oxygen, in admixture of the small fraction the minimum. The that will test as oxygen index (OI) vertical test specimens under results are defined with nitrogen specified values.

What is the Minimum Volume Fraction?

Minimum volume and for fiber failure of the fractions in the range 0<vf<0.56 fraction gradual decrease in composite (Vein) is 0.56 failure. As increases from value (46MPa) to ~20MPa at fraction fibers does not lead to a composite range there in this fiber is a tensile strength matrix vf=0.56.

What is Oxygen Index?

It is defined as, of oxygen and combustion conditions volume percent, in expressed as under equilibrium a mixture the minimum concentration of material initially at nitrogen that will support flaming room temperature of candle-like burning.
