• ASTM Standards: The American Society for Testing and Materials (ASTM) provides specifications that can be critical for construction-related products.

Quality Control Checkpoints

Quality control (QC) is typically structured around three main checkpoints:

1. Incoming Quality Control (IQC): This initial phase involves inspecting raw materials upon arrival at the manufacturing facility. Suppliers should have stringent IQC protocols to reject substandard materials before production begins.

2. In-Process Quality Control (IPQC): During manufacturing, regular checks are performed to monitor process parameters and product quality. This includes testing for viscosity, curing time, and adhesion properties.

3. Final Quality Control (FQC): Once production is complete, FQC ensures that the final products meet all specifications before they are packaged and shipped. This may involve functional testing and performance evaluations.

Common Testing Methods

B2B buyers should be aware of common testing methods that manufacturers may employ to ensure product quality:

• Tensile Strength Testing: Measures the force required to break a sealant, indicating its durability.
• Elongation Testing: Assesses how much a sealant can stretch before breaking, which is vital for applications requiring flexibility.
• Adhesion Testing: Evaluates how well the sealant adheres to various substrates, an important factor in its effectiveness.

Verifying Supplier Quality Control

For international B2B buyers, particularly those from Africa, South America, the Middle East, and Europe, verifying a supplier’s quality control processes is essential. Here are actionable steps:
