What are the three common test methods for edge pressure testing machines?

What are the three common test methods for edge pressure testing machines? The edge pressure tester can do strength tests such as edge pressure, ring pressure, vertical pressure, and flat pressure. Is there a difference in the calculation method between them? Here, Haida Xiaobian introduces the most common three test calculation methods for everyone's reference:

1 , the compressive strength of the vertical edge according to the calculation method, expressed in N / m

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â F Ã— 103

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â R= Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ........... Formula ( 1 )

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â L

Wherein: R â€” vertical edge compressive strength N/m ;

Â Â Â Â Â Â Â F - maximum force value , N ;

Â Â Â Â Â Â Â Â L - Size of the long edge of the pattern, mm .

2. Calculation method of ring pressure strength (average value of longitudinal force and longitudinal force respectively):

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â F

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â R= Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ............. ( 2 )

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 152

Among them: R â€” ring pressure strength, kN/m ;

Â Â Â Â Â Â Â Â F - the force reading when the sample is crushed, N;

Â Â Â Â Â 152 - specimen length, mm

Report average ring pressure R, accurate to 0.01kN/m

If necessary, calculate the ring pressure strength index according to ( 3 ) to the nearest 0.1N â€¢ m/g .

Â Â Â Â Â Â Â Â Â Â Â Â 1000R

Â Â Rd= Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ............. ( 3 )

Â Â Â Â Â Â Â Â Â Â Â Â Â Â W

In the formula, Rd â€”Cylindrical compressive strength index, N â€¢ m/g ;

Â Â Â Â Â Â R â€” Ring pressure strength: kN/m

Â Â Â Â Â W - quantitative, g/ m2 .

3 , the determination of vertical compression strength

Calculate the average value of the vertical pressure F ( N )

Â Â Â Â Â Â Â Â Â Â Â Â F

Â Â Â Â R= Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â .............. ( 4 )

Â Â Â Â Â Â Â Â Â Â Â Â 150

Press ( 1 ) Calculate Intensity

Or in Â Â R - compressive strength, kN/m ;

Â Â Â Â Â Â Â Â F - the force value read when the sample pressure, N ;

Â Â Â Â Â Â 150 - specimen length, mm

Reported average pressure intensity R , exact value 0.01kN/m
