SPECIFICATIONS
・
Hardness test for rubber and plastic.
APPLICATIONS
This product is compliant with the following
standards with regards to Indenter shape, size,
dimensions, and spring force.
JIS K 6253
『
Rubber, vulcanized or thermoplastic - Determination
of hardness
』
ISO 7619(E)

STANDARDS
・
This product is to be used as Hardness Measuring Instrument for
plastic and rubber. Please use only as directed.
・
Only use within applicable measuring range for each model. Use
beyond specified range may cause errors or damage to instrument.
・
Never press indenter against hard surface, such as glass or metal,
with the exception of testing using the Wear Test Block.
・
Do not apply force greater than 2-3 times force specified by the
relevant standards (JIS, ASTM, ISO, DIN, etc.) Excessive force
may affect accuracy and cause damage to the instrument.
・
Do not apply lateral pressure or move the indenter when in contact
with test sample.
・
Instrument is designed for using in vertical orientation with
downward pressure. Use in horizontal or upward direction will result
in inaccurate measurements.
・
Please Note – Measurements taken by this instrument will vary
from those taken using a different measurement standard, such as
JIS K6301, etc.
・
This is a precision measurement instrument, Do not drop or apply
excessive force as it may result in inaccuracy.
・
Do not use in wet or oily locations.
・
Do not disassemble or modify.
・
Do not use organic solvents (thinner, benzine, etc.) to clean.
Please insure that Test Samples meet the following conditions.
・
