Testing Capabilities
Mechanical Testing
1.Tear Strength (ASTM D624)
This test measures the maximum force required to cause
the conventional vulcanized rubber and thermoplastic
elastomers to grow by tearing the rubber.
2.Tensile stress-strain (ASTM D412)
This test measures the force required to break a vulcanized
thermoset rubbers and thermoplastic elastomers and
the extent to which it stretches or elongates to
that breaking point.
3.Hardness (ASTM D2240)
This test measures the hardness of the vulcanized thermoset
rubbers and elastomeric material based on either
initial indentation or indentation after a specified
period of time.
4.Heat Resistance (ASTM D573)
This test measures the physical properties of vulcanized
rubber subjected to elevated temperature.
5.Compression Set (ASTM D395)
This test measures the ability of rubber compounds
to retain elastic properties after prolonged action
of compressive stresses.
6.Low Temperature Retraction (ASTM D1329)
This test describes a temperature-retraction procedure
for rapid evaluation of crystallization effects and
for comparing viscoelastic properties of rubber and
rubber-like materials at low temperatures.
7.Low Temperature Brittleness (ASTM D2137)
This test determines the lowest temperature at which
rubber vulcanizates will not exhibit fractures when
subjected to specified impact condition.
8.Density (ASTM D297)
This test method is used for quality control in rubber
product manufacturing operations, for research and
development testing of elastomers.
Chemical Testing
1.Fourier Transform Infrared Spectroscopy (FTIR)
This test technique based on infrared examination of
pyrolysis product is used to identify different kind
of elastomeric material and for qualitative and quantitative
analysis of organic contaminatnts.
2.Gas Chromatography-Mass Spectroscopy (GCMS) - DHS
This test technique is used to identify and quantify
volatile and semi-volatile organic compounds in complex
mixtures.
3.Ion Chromatography (IC)
This test technique is used to identify and quantify
ionic impurities.
4.Thermogravimetric Analyser (TGA)
This test technique is used for composition analysis
and thermal stability of material.
Biological Testing
1.Physiochemical (USP 23 <381>)
This test method helps to determine the stability and
properties of a product in contact with the closures
for injection used in pharmaceutical. It includes the
following tests: turbidity, pH change, reducing agents,
heavy metals, and total extractables tests.
2.Biological Reactivity, in Vivo (USP Class VI)
This test determines the biological reaction of animals
to elastomers, plastics and other polymeric materials
with direct or indirect contact, or by the injection
of the extracts prepared from the material under
test. The classification is based on the responses
to a series of in vivo tests for which extracts and
materials are specified.
3.Rubber Closures for containers for aqueous parenteral
preparations, for powders and for freeze-dried powder
(EP329)
This test is for rubber closures for containers for
aqueous parenteral preparations, for powders and for
freeze-dried powders are made of materials obtained
by vulcanization of macromolecular organic substances,
with appropriate additives. Rubber closures may be
classified in 2 types: type I closures are those which
meet the strictest requirements and which are to be
preferred; type II closures are those which, having
mechanical properties suitable for special uses, cannot
meet requirements as severe as those for the first
category of their chemical composition. |
