Product Details
Brand Name: | Zotai | Place of Origin: | China | Model Number: | ZT-1011C |
Product Description
Introduction :
Sponge Shore C Hardness Gauge Foam Hardness Tester is applied to low-hardness testing for foam, sponge and microporous material of shoes. This product meets the standards of HG/T2489 and other related standards.
Specification & parameter:
Dial value | 0~100HW |
Recommended test range | 10~90HW |
Dimention | 115×60×25 mm |
Pressure needle stroke | 2.5mm |
Pressure needle head size | SR2.5 mm |
Net weight | 0.5 kg |
Usage:
The specimen placed in a hard, flat surface, hold the hardness, the pressure foot pressure needle in the hole from the specimen edge at least 12mm, smooth enough to put pressure on the pressure in the sample, can not have any vibration, and pressure sufficient to maintain the parallel On the sample surface, so pressure needle vertically onto the sample, the force imposed pressure to be just enough to make full and complete access to the sample, unless otherwise specified, pressure foot and the specimen must be exactly 1 second after touch In reading, if reading the other must be that time interval, the sample distance of at least 6mm in different locations measured hardness value of 5 times the mean value.
Terms of Use:
1, Determination of hardness should be checked before the pointer in the free state should point zero. If the amount of deviation from the zero pointer, you can compress the upper right corner loose screws, rotating the surface, pointing to zero.And then the hardness of pressure on the glass face and the pressure foot pressure needle in close contact on the glass surface, the pointer should point to 100 + /-1HA, if not point to 100 + /-1HA, you can press the pressure needle slightly Several times, such as still means 100 + /-1HA, then the hardness can not be used.Shore hardness test if the use of the rack, you can toggle the handle, so that load weight be the bench rose to lift the pressure foot needle flat face in close contact with the pressure on the glass table, the pointer should point to 100 + /-1HA. If we do not mean 100 + /-1HA, the adjustable flat bench adjusting screw, if the adjusted pointer still refers to the 100 + /-1HA, it is best to send appropriate adjustment of production units.
2, Rubber sample and test temperature requirements;
a,Rubber specimen thickness of not less than 6mm, the width of not less than 15mm, length not less than 35mm, less than 6mm thick sample, the overlap can be measured the same film, but not more than 3 layers. And require up and down parallel to the film.
b,Test when the temperature is 23 ℃ ± 5 ℃, the former test hardness kept at this temperature for at least 1 hour.
c,Plastic sample and test temperature requirements;
d, plastic sample square with a side length of 50mm, thickness 6mm. Also allow the use of 50 × 15mm samples.
e,Where possible, the specimen before the test in the laboratory in accordance with the provisions of the standard GB/T2941-1991 temperature adjustment. Comparison test or series of tests must be carried out at the same temperature.
f,Rubber and plastic sample surface should be smooth, flat, should not have mechanical damage and impurities and other defects.
g,Hardness using 35,000 times, suggested that each use about 10,000 check spring pressure provided by GB531 and needle gauges and pressure between the end of the shape and size.
h,Hardness after use, into the apparatus or equipment inside the box, place a dry place to prevent damp.
i,Determination of fixed charge down the shelves at the bottom of a small shaft and table, please note that often wipe clean, coated with a small amount of anti-rust oil to prevent rust.
j,Shore hardness with time, when the A-type hardness of less than 10HA indication is not accurate when the measurement results can not be used. A type of hardness measurement is recommended for outside 90HA-D hardness.
