 Elcometer 1720 Abrasion, Scrubbing & Washability Tester
|
|
|
This robust,
reliable and extremely flexible machine has been designed for
testing the washability, brushability and abrasion resistance
of a wide range of materials, including; paint, lacquers, inks,
coatings, leather, wood, plastics, printed material, fabrics,
etc.
The Elcometer
1720 is available in two versions:
-
2
working stations - undertakes two tests at the same time.
-
4
working stations (as shown in picture) - allows the operator
to test up to 4 samples, or 4 different tests at the same time,
dramatically increasing your productivity.
A kit is
also available - allowing you to upgrade your 2 working station
model to a 4 working station model
|
Simple
to use and adaptable, the Elcometer 1720 has a large amount of
functionality built in, including:
-
Double
Counter - Double function and independent displays make it easy
to repeat and follow test sequences:
-
pre-selection
count function - set the number of cycles desired per sequence
and leave the machine to automatically stop.
-
total count function - indicates the total number of cycles
after one or several sequences.
-
Variable
Speeds - with two interchangeable operating modes, the machine's
performance can be optimised according to the type of tests:
-
fixed
speed mode - 37 cycles per minute (ASTM, DIN, ISO and EN
test methods).
-
variable speed mode - the operator can select a speed from
15 to 65 cycles per minute. (1 cycle = 1 motion back and
forth of the carriage).
-
Carriage
- the carriage is designed with multiple functionality:
-
adjustable
stroke length - user defined stroke length from 30 to 290mm
(1.2 to 11.4").
-
test
tool locator - the brushes or abrasive pads are located
in the chambers and are guided without superfluous devices
or mechanisms, making it easy to install or remove alternative
test tools.
-
Individual
Dosers - using this device the flow of test liquids can be regulated
for each test location, independently.
-
Rapid
Specimen Fastening System - aluminium frames are held in place
by quick release clamps. Each frame is fitted with a gasket
which both enclose and divide the test specimen - allowing effective
and comparative tests to be carried out simultaneously.
-
Chassis
- made from thick anodised aluminium, the Elcometer 1720 is
both self supporting and robust, giving complete confidence
in the durability of the machine, no matter how long the test
period.
The Elcometer
1720 is equipped with either 2 or 4 working stations, each path
separated by a water-tight gasket frame. This design enables up
to 2 or 4 simultaneous comparative tests to be carried out. Dimensions
are adapted so that 2 strokes of different products can be positioned
onto a same specimen, e.g. PVC Leneta test panel. As a result
a substantial economy of consumables can be achieved. For this
purpose, the optional Elcometer 3508/1
2 Reservoir Film Applicator facilitates the sample preparation.

| The
Elcometer 1720 can undertake tests according to a wide range of
different standards or test methods, by simply changing the abrasive
tools. |
| |
| Tool
1: DIN 53778 (replaced by EN ISO DIN 11998 in Dec 2001)Wild
boar hair brush and stainless steel brush holder, standardised mass:
250g (8.8°z) |
Tool 6:
EN ISO DIN 11998 Aluminium holder, standardised mass: 135g (4.8°z),
and abrasive pad
|
| Tool
2: ASTM D2486Nylon bristle brush and stainless steel brush holder,
standardised mass: 454g (16°z) |
Tool 7:
Polyvalent Holder Stainless Steel holder, fitted with a fastening
screw to fix abrasive textile or paper, and other similar materials
as well. mass: 454g (16°z)
|
| Tool
3: ASTM D4213-92 / D4828Sponge and stainless steel brush holder,
standardised mass: 500g (17.6°z) |
Tool 8:
Renault D45 1010, ISO 105X12, ASTM F1319, EN 233Also known as
the "Crockmeter", specially designed for testing colour
fastness of fabrics. Assembly including adapter, removable stainless
steel cylindrical rod (200g / 7.0°z), test felt or textile fixing
ring and a set of additional weights: 2 x 100g (3.5°z); 1 x 100g
( ); 1 x 500g (16.6°z)
|
Tool
4: ASTM D3450Sponge and stainless steel brush holder, standardised
mass: 750g (26.5°z)
|
Tool 9:
GME 60269 Tool for testing the resistance to abrasion of automotive
components - similar to the "Crockmeter" but holding
a felt disc of 10mm (0.4") diameter and 10mm (0.4")
thick, working under a mass of 400g (14.1°z)
|
| Tool
5: ASTM 4213-96Sponge and stainless steel brush holder, adapted
mass: 232g (8.2°z) and sponge (with 2 integrated abrasive pads -
one on each side |
Tool
10: EN 60730 (resistance to markings)Assembly for testing the
quality of markings or similar coatings. A felt rubs the test surface
over a length of 30mm (1.2"), under standardised time, speed
and load conditions. The assembly is screwed into the carriage.
Comes complete with a height adjustable arm fastening the felt disc,
a rod for holding the weights, and thanks to the combination of
weights supplied, the test load can be varied between 150 - 1700g
(5.3 - 60°z) in 50g (1.8°z) steps. |
