Introduction
The bottle testing is necessary for various industries. Since it assists in analyzing the production
provide, assist in third-party verification and provide qualification data. The water bottle was chosen by
this group so that to conduct the test on it. The test was carried so that to assist in identifying the
material composition used in making that particular product chosen. There were some methods that
were used in testing for the water bottle like melt flow testing, rheology, mechanical testing and thermal
testing.
Melt Flow Testing
A melt flow test is used in measuring the melt flow rate and melt volume rate of a molten polymer.
The values are taken at a certain temperature and with a certain mass applied, dependent on the
material. The test system consists of (Berger, 2012, p. 213);
 A heated barrel with a die which can be removed.
 A piston fitting in the barrel.
 Temperature control of the barrel.
 Masses applying various weights.
 An encoder for measuring piston deflection.
 A die plug for keeping the thinner material in the barrel waiting for the test to begin.
 Hastelloy barrel for chemically aggressive materials.
 Control data and analysis software package for machine control, analyzing data and inputting
test parameters.
Rheology
A rheometer is used in measuring the rheological properties of molten polymers when carrying
shear rates and temperatures. In order to determine the features of polymer, a wide number of
accessories are used (Duncan, 2018, p. 124). The test system consists of;
 A rigid test frame with motor driven crosshead.
 Interchangeable capillary dies varying test types
 A heated oven with pressure transducers
 Control and data analysis software package to input test parameters for a test method, perform
calculations, analyze data and control the machine.
 Laser detectors are also needed for die swell measurements
 Motor and pulley for measuring the melt strength.
Thermal Testing
Thermal testing entails measuring the Heat Deflection Temperature (HDT). Heat Deflection
Temperature Deflection Temperature is a 3-point bend test measuring the temperature at which the
sample either penetrates or deflects (Frantta, 2009, p. 321). This type of test system consists of
 A bath containing the heating medium and this can be AL oxide powder or silicone oil
 LVDT for measuring deflection on the test stations.

 Control and data analysis software package to analyze data, performing in calculations and input
test parameters for a test method
Impact testing – Drop Tower
A drop tower can be used in measuring the energy absorbed by a sample or applying a set amount of
damages to a specimen at impact velocities (Frantta, 2009, p. 89). This test consists of;
 A test fixture for holding the specimen
 A load sensor with an insert shaped for the application.
 A falling mass guided by columns
 Data acquisition system with the high acquisition rate
 Control and data analysis software to input test parameters for a test method, collect data for
the DAS, controlling the machine, performing calculations and analyze data.
 An environmental chamber.
 Automation system to test batches of samples.
 Anti-rebound device for catching the mass after a rebound.
Mechanical Testing
This type of testing is done for accurate measuring of physical strengths of solid materials (parah,
2011, p. 122). The test system mainly consists of text featuring to help in supporting the specimen,
measuring transducers for covering the range of applied loads and strain measurements, reaction test
load frame of a suitable capacity to meet with the application and control analysis for controlling
reaction of frame, measuring the calculations for Breakpoint and Peak loads, export test data to network
database and performing statistical analysis of a sample batch tested (Struthers, 2012, p. 56). Types of
test include;
 Coefficient of friction
 Compression
 Peel, friction, and friction
 Shear
 Tension.
Importance of water bottle testing
The testing of water bottles is important for the following reasons;
 Testing of water bottles assists in knowing its efficiency to withstand different environmental
conditions and its resistance against rough handling.
 To determine the shelf life and quality standards as per the application
Conclusion
It is important to carry out testing in bottles since it assists is in knowing the composition of materials
used in the item
