Plastic Pipe Hydrostatic and Burst Testing Machine

PIPE HYDROSTATIC TESTING MACHINE MAINTENANCE METHODS & PRECAUTIONS ISO1167

When using a pipe hydrostatic testing machine, in addition to paying attention to certain precautions, it’s also crucial to understand the machine’s maintenance methods. Below, we’ll guide you through them.   The pipe burst test involves rapidly and continuously applying liquid pressure to a given section of plastic pipe sample, causing it to rupture within a short time. The pressure value at the time of rupture is recorded, and the circumferential stress is calculated. The pressure control system of the hydrostatic [...]

Vicat Softening Point & Heat Deflection Temperature – Common Plastic Test Methods

Vicat Softening Temperature Applicable standards: ASTM D 1525, ISO 306, DIN 53460 The test for Vicat softening temperature mainly determines the temperature at which a material softens rapidly. A plastic specimen is immersed in a liquid heat-transfer medium. Under a specified load and constant linear heating rate, the temperature at which a 1 mm² flat-tipped indenter penetrates 1 mm into the specimen is defined as the Vicat softening temperature (VST). ISO 306 specifies two load grades:Grade A: 10 N load Grade B: 50 [...]

Digital Fabric Elmendorf Tearing Strength Tester

FACTORS AFFECT THE TEAR STRENGTH OF FABRICS

Tearing refers to the phenomenon where a fabric tears due to concentrated load on a localized area of ​​yarn. Examples include: the fabric getting caught on an object, causing localized stress on the yarns and creating a tear; or a section of the fabric being gripped and torn in two.   The main factors affecting fabric tear strength are: ASTM D 1424 ISO 13937 Fabric Textile Elmendorf Tearing Strength Tester 1) Yarn properties:   ① Yarn linear density: This is easy to understand; coarser yarns [...]

WHAT IS THE PRINCIPLE BEHIND THE FABRIC PILLING TEST?

The principle of the fabric pilling test is to simulate the friction experienced by a fabric in actual use, causing the surface fibers to break, fuzz, and further entangle into balls, thereby evaluating its anti-pilling performance. The specific analysis is as follows:   Testing Process   Friction: Under the action of friction, the surface fibers of the fabric are affected by mechanical force, causing them to break or loosen.   Fuzzing Stage: After the fibers break or loosen, fuzz is formed, protruding from the fabric surface.   Pilling [...]

Fabric Air Permeability Tester

FACTORS AFFECTING FABRIC AIR PERMEABILITY

The ability of air to pass through a fabric is known as its air permeability. It directly impacts its wearability. For example, summer fabrics require good air permeability, while winter outerwear should have lower air permeability to ensure windproofness and prevent heat loss. air permeability is crucial for certain fabric applications in defense and industry. For example, parachutes require high air permeability, and tarpaulins must be durable and breathable. Fabric air permeability is determined by the number and size of spaces between [...]
