Raw material testing refers to the process of analyzing the physical, chemical, mechanical, thermal, and other properties of unprocessed or minimally processed materials that go into manufacturing end products. The goal is to ensure that what you’re sourcing meets required standards of safety, performance, and regulatory compliance.

Identity & purity: Making sure the material is what the supplier claims, with no adulterants.
Physical properties: Such as tensile strength, hardness, density, moisture, etc.
Chemical composition & contaminants: Detection of harmful substances, heavy metals, impurities.
Thermal behavior: Melting point, thermal stability, heat deflection, etc.
Electrical properties (if relevant): Conductivity, dielectric strength, etc.
Durability / degradation: How the material responds over time, exposure to environment, UV, weather.
Testing raw materials helps preempt problems during processing and product usage.

Many industries (automotive, medical device, aerospace, food packaging, etc.) are tightly regulated. Using noncompliant raw material can lead to warnings, recalls, or lost market access. Tests from accredited labs, such as those with NABL accreditation, are often required. Kiyo R&D Lab holds NABL certification, which assures competence and traceability.

Finding defects early (raw materials) saves money versus discovering them after fabrication or in finished products. There’s less waste, fewer production delays, and less rework.
Customers expect that products perform safely under intended use. Raw materials that fail prematurely can lead to accidents, malfunction, or harmful exposure. Rigorous testing ensures that materials will perform as promised.
Brands that emphasize quality often gain trust among end users. Meeting international standards, having third-party lab certifications, and being transparent about quality can be a differentiator.
Depending on the material and its intended use, different tests are required. Here are some of the commonly done:
While there are many laboratories in India, choosing the right one requires care. Some of the challenges include:
Quality variability among labs: Not all labs maintain the same standards of precision, traceability, or accreditation.
Turnaround time: Delays in getting results can stall production.
Cost vs Value: Low-cost labs might cut corners; what you save short term might cost more in rejects or failures.
Standard compliance: Different industries require different national/international standards (ISO, ASTM, BIS, etc.); ensuring the lab can test to the proper standards is essential.
Data reliability and reporting: Precise measurement, clean reports, verifiable data, sometimes with photographic or instrument traceability.
Kiyo R&D Lab stands out in several ways:
NABL Accreditation: Ensures that test methods, equipment calibration, staff competency, and reports are recognized and trusted.

Be clear about which properties must be tested. Provide specifications, standards, tolerances.
And check whether their scope covers the required tests. NABL accreditation is a strong indicator. Kiyo R&D Lab’s accreditation helps ensure this.

Proper collection, labeling, handling, and storage of raw material samples are vital to avoid misleading results.
More than one batch, or random checks, to monitor consistency over time.
ASTM, ISO, BIS or internal standard methods — lab should follow accepted, validated procedures.
Seek clarity if results are borderline. Understand implications for processing or product performance.
If testing reveals non-conformance, plan corrective steps — either change raw material source, adjust processing, or refine specifications.
