Aluminum Silicate Fiber Board Testing Items and Standards

Aluminum silicate fiber board is a high-temperature insulation material used in kilns, boilers and high-temperature pipes. The quality should be tested for density, thermal conductivity and heating shrinkage. The bulk density is measured by the weight and volume of the sample. It should be within the range specified in the product standard to ensure both strength and thermal insulation perform...

Insulation Nail Quality Inspection and Testing Items

Insulation nails are widely used to fix insulation boards on walls and roofs. To guarantee the fixing strength and service life, each batch should be tested according to standard procedures. The tensile pull-out force is the most important index. A sample of the nail is fixed into the insulation board, and a tensile testing machine pulls it vertically until it is detached. The pull-out force s...

Rubber Plastic Insulation Board Testing Items and Standards

Rubber plastic insulation products, including board and pipe types, are widely used for cold and hot pipe insulation. The quality should be checked by the apparent density, thermal conductivity and dimensional stability. Apparent density is measured according to the standard method. A sample of specified size is weighed and the density is calculated. The value should be within the range requir...

Non-Woven Geotextile Testing Items and Standards

Non-woven geotextile is an important geosynthetic material. To ensure its service performance, strict quality testing must be carried out before use. Main testing items include: unit area mass, thickness, tensile strength and elongation at break, tearing strength, puncture resistance, water permeability coefficient, effective pore size and anti-aging performance. Testing method: sample accordi...

Glass Wool Testing Items and Standards

Glass wool is a thermal insulation material with excellent performance. To ensure its quality, strict testing must be carried out before use. Main testing items include: density, thermal conductivity, thickness, tensile strength, moisture content, combustion performance and fiber diameter. Testing method: measure the density and thickness with a ruler and balance, test the thermal conductivity...

Grass Grid Quality Inspection and Testing Items

Grass grid (grass paver grid) is a geotechnical material used for slope protection, parking lot greening and lawn reinforcement. Its quality is directly related to the bearing capacity and greening effect, so strict inspection must be carried out before use. Main testing items include: raw material (HDPE/PP virgin or recycled material content), appearance quality, size and tolerance, unit weig...

HDPE Geomembrane Welding Rod Quality Inspection and Testing Items

The HDPE geomembrane welding rod (plastic welding rod) is a key consumable used to join HDPE geomembrane sheets by hot air or extrusion welding. Its quality directly determines the sealing reliability of the whole anti-seepage system, so strict inspection is required before use. Main testing items include: raw material grade (virgin HDPE resin content), diameter uniformity and ovality, tensile...
