Impa ct Directio n:

Ideal Leeb Hardness Testing is a downward straight testing
method. As a result of gravity, the test should be amended when
measuring other directions in order to measuring correct
hardness value of material. As long as you correctly choose the
impact direction, ISH-PHA Hardness Tester can automatically be
amended.
On measurement mode, press “Imp. ”button to select the impact
direction.

Convert scale:

ISH-PHA Hardness Tester can automatically convert HLD values
to other hardness scales HRC, HRB, HB, HV, HSD or tensile
strength (MPa) according to a particular material group (e.g.
steel, aluminum etc.)
In measurement mode, press “Convert” button to convert to all
common hardness scales or tensile strength: Press the button

continuously, the scale according to following sequence: HRC→
HRB→HB→HV→HSD→MPa→ HRC…

Note

:

1. The conversion value is “---” indicated the conversion is out of
range.

2. When you set the conversion from hardness scale to tensile
strength or from tensile strength to hardness scale, you must be
reset the material group.

3. Conversion value only supplies the general reference, which
may result in some offset. Precisely conversion generally needs
related comparative tests.

4. When you change the hardness scales, the current impact
time's counter of measuring interface will be clear to “0”.

5. Default setting for the conversion is “HRC”.

Samp le Prepar ation:

Inap propria te sample will cau se a grea t m easuremen t erro r.
Ther efore, users should make the necessar y hand ling and
prep aration u nder the orig inal cond itions of sam ple.
Prep aration of the sa mple and th e s urface of tes t s hould be
coin cident wi th the follow ing basic r equiremen ts:

1) Dur ing the pro cess of sam ple surfa ce pre paratio n, u sers
shou ld avo id the imp acts of cold p ro cessing and the rmal
proc essing.

2) The sample surface is plane for bett er, the test sur face
shou ld be with a m etallic sh een, and not invol ve oxide laye r
orot her stains.

3) Rou ghness of the t est surfa ce Ra ≤ 1.6

4) Sample must be of su ffic ient quality and rigidi ty. If i t's la ck
of q uality an d rigidit y, it may caus e displac ement or shaking i n
the pr ocess of test ing impac t, which can le ad to large e rrors.
Gene rally spe aking, if the s ample qua lity is more th an 5kg can
be di rectly tes ted; if the sample qua lity is 2~5 kgs, the sample
shou ld b e taken in fixa tion test b y means of appr opriate
clam ping; if t he s ample quality i s 0. 1~2kgs, the sam ple
shou ld be c onducted coup ling bef ore th e te st; if the sampl e
qu a l i t y i s l e s s t h an 0. 1 k g , t h i s h a r dn e s s t e s t e r is
inap propria te to use.
Coup ling meth od: Testing sam ple's back should be p repared
to make a pl ane as a sup porting surf ace wit h a s mooth
form ation. Fi lling with a li ttle coup ling substa nce (Indu stry
Vaselin e can b e used), users can no w pres s to th e surf ace of
the sup porting obje ct (The weigh t of sup porting ob ject should
be mor e th an 5 kg, and it ca n be rep laced by test block) to
stic k into integr ation.

5) S amples sh ould be t hick enou gh and wi th sufficie nt surfac e
abso rption layered. If users use D-t ype im pact device, the
thic kness of sa mple should n ot be less th an 5mm, and sur face
abso rption layer (or surfac e-hardeni ng laye r) s hould not b e
less t han 0.8mm. To accurat ely measure t he h ardness o f th e
mate rial, the bes t way is to rem ove the surfa ce-hard ening

mater ial, the be st way is to remo ve the surfac e-hardeni ng
laye r by proces si ng.

6) Wh en testi ng sample s urf ace is not hor izontal, th e
curv ature rad ius of t esting an d nearby surf ace shoul d be
larg er t han 30mm. And approp riate suppo rting ring shou ld b e
elec ted and ins talled.

7) A s ample should not be with magnet ic. The signal of the
impa ct device wou ld be serio usly inter fered in the w or k by the
magn etic, whi ch m ay cause in accurate te st result s.

Meas uring Ste ps:

Load ing: S imply load the impact devic e by sliding the loadi ng
tube f orward.

Plac e: Then pla ce and hold the impact device on th e surface
of the test piece at the desir ed test p oint. Impact ind irectio n

shou ld be verti ca l with the te st of surface .

Burs t imp act (Measure ): Trigger the impact by pres sing the
rele ase butt on. The har dness va lue will be insta ntaneousl y
disp layed.

Read o ff t he test resul t from LCD. For e xample:

The cu rrent mean va lue: 785H LD
Conv ersions t o HRC: 58.6HR C
The me an value of H RC: 58.5HRC
Repe ating the above steps, users can carry out tests in more

Note : Gene rally, ea ch measu rement l ocation of sam ple is
cond ucted f or th e five tests . The “ S” (diffe rence o f maxim um
valu e and minimum va lue) value s must be less than 15 HL.
The d istance between any two impa ct posit ion shou ld be ≥3

surf ace Ra≤ 1.6.

2) The sha pe of sample su rface
Leeb testi ng princ iple deman ds the velocit y of rebound and impac t
are on t he same lin e, because th e impact bo dy is moving in a metal
tube . Even if the ve locity o f rebound and imp act are n ot on the same
line , it also can s how h ardness fo r sur e, but the impa ct bo dy wo uld
coll ide wi th t ube wa ll w hen it rebou nds, which will affect t he v elocity
of rebou nd. Ther efore, a g reater error is on t est ac curacy. W hen the
radi us of curvatu re of the t esting sampl e sur face is smaller, th e
solu tion is the use of suitable var iant suppo rting ci rcle. If users
requ ire special sup porting circ le, we can contribut e to design and
proc ess.

3) The wei ght of the samp le
If the sa mple weight must be larg er than or equal to 5kg, and not

prop er tr eatment (I t is neces sary to in crease the supp orting or
moun ting th rough coupling comp ress on larger weig ht test ing sta nd),
and the test ing result s can be ac hieved in accur acy. There shou ld be
a certain area at the testi ng po ints (the area require d to meet a set of
test ing points) and no vi bration or shak ing. I f th e we ight i s not

4) The sam ple stabili ty
Any effective test s need to mi nimize possibl e inter ference from

fact ors effect the ac curacy of tes ting for th e use of refere nce:
