Material testing is important for all industries as it ensures the quality and safety of the end product.  Usually it is done at the end of the manufacturing process.  It is better to test individual parts of a product rather than the whole product at  one time.  Here are a few ways by which you can determine the quality of a  material  

There are many types of material testing that can be done on products.  If your company doesn’t have the facilities for testing, you can outsource it to material testing laboratories.  Here are a few types of material testing 

• TENSILE TESTING: Tensile testing is done to check how a material behaves when axial loads are applied to it.  This type of testing is mostly done on plastic, metal, rubber and fabric materials.  For checking the tensile strength, the material is exposed to both high and low temperatures. 

• STRESS TESTING: Stress testing is done to determine a material’s ability to resist compressive  force applied to break it.  The time period force which the force is resisted is also  recorded.   

• BEND TESTING: For testing the flexibility of a product, a bend test is done.  There are two  types of bend testing that can be done in a material testing lab  namely 3 point and 4 point.  In this type of testing, either the load measurement or the breaking point of a material is determined.   

• BOND STRENGTH TESTING: Bond strength testing involves determining the amount of stress require to break the adhesive bond between two materials.  This type of test is mostly done on orthodontics and medical adhesives.   

Here are some other useful tips that you can take to determine the quality of a material.   

PRE-INSPECTION  

Material testing is also known as inbound or receiving  inspect here are some steps that can be followed before the actual inspection.   

The receiving department in your organization will already have its own processes in place  which might include verifying and recording the quantity of material received, checking the order purchase number and verifying whether the order is complete 

• PHYSICAL INSPECTION  

It is always a good idea to take photos and videos of the material after you receive it.  There are many workflow management tools  that enable you to tag the photos you take for easy storage in inspection forms.   

• CHECK  PROJECT SPECIFICATIONS  

This is a critical step that needs to be taken.  Check the specifications of the project to confirm whether the material you received from material testing labs in India meets the required specifications.  Any part or component whether liquid or metal that does not meet the standards should never pass inspection 

Once you know the specifications of the project, you can confirm whether the materials meet the contract requirements and purchase order 

There are other different types of testing that can be done in a material testing lab   like shear test, peel test, tear strength testing, creep resistance and elastic limit testing.   

SMSLA Global is an accredited material testing laboratory.  Our material testing services include food packaging material testing for seafood and other sectors.  We have our laboratories are in Ahmedabad, Coimbatore, Cochin, Mumbai, Hyderabad,  Chennai, Coimbatore, and  Visakhapatnam.   

Materials testing is a technique used to check the physical and mechanical properties of raw materials and various components. It is done for many reasons and provides vital information about tested materials, prototypes, and product samples. The data gathered from testing can be useful for engineers, product designers, and product managers. Material testing is usually done in a material testing lab. 

Testing is done for meeting regulatory requirements, selecting the right materials for an application, assessing product design, and confirming product specifications. 

DIFFERENT TYPES OF MATERIALS TESTING  

There are many types of testing that can be done in material testing laboratories. It can help to understand what material would best suit a certain purpose. Testing methods can include: 

WE CONDUCT DIFFERENT TYPES OF MATERIALS TESTING  WHICH ARE AS FOLLOWS  

1.PLASTIC INDUSTRY: As Per IS 9845 Laboratory to assure the quality of plastic product By Overall Migration & Color Migration Test, For Specific Migration ICPMS can be used to identify Trace Metals  and GC/MS can be used to identify harmful chemicals and toxins Test as to be done by Bis(2-ethylhexyl) phthalate. 

2. FOOD PROCESSING INDUSTRY: Food manufacturers use plastics for packaging purposes. Overall Migration & Color Migration Test can be done for 10 days in Oven (40°C) to  Identify the taste and Odor in Plastics, So we can find solvent residue in plastics. GC/MS headspace analysis can help identify contaminants in the food. Other than migration test can we check bursting strength. 

Other regular tests being done for these industry are  

• ANALYTICAL CHEMISTRY TRAINING: This type of testing is mostly done on food products. The different components of a food product are chemically separated and tested for PH, additives, preservatives, contaminants, and color. 

• MICROBIOLOGY TESTING: Microbiology testing is done to identify harmful microorganisms and bacteria in food products that are harmful to health. 

• CONTAMINANT ANALYSIS: Contaminant analysis is done to determine the level of pesticides and heavy metals in food.   

WHICH INDUSTRIES CAN BENEFIT FROM USING MATERIAL TESTING IN QUALITY CONTROL PROCESSES?  

Material testing can be used in a number of industries to improve quality control processes: 

1. PLASTIC INDUSTRY: Many manufacturers use plastics during the product design and packaging stage. During the last few years, many companies and consumers have grown apprehensive about the significant amount of toxins in manufactured plastic products. Material testing processes like FTIR and GC/MS can be used to identify harmful chemicals and toxins. 

2. PHARMACEUTICAL INDUSTRY: Many pharmaceutical labs use solvents like ethanol while producing their products but if these solvents are not properly eliminated, they can affect the quality of the end product. Medicines are ingested by people so these solvents have to be removed so that they don’t pose any significant health hazards.   

3. FOOD PROCESSING INDUSTRY: Food manufacturers use plastics for packaging purposes. Harmful toxins and solvent residue in plastics can completely alter the taste or odor of the food. GC/MS headspace analysis can help identify contaminants in the food.   

SMSLA is one of the top material testing labs in India offering services like product testing, environment testing, and inspection services.
