Free phenol by gas chromatography

ISO 8974 Standard: Method for determining the residual phenol content of phenolic resins by gas chromatography. The resin is dissolved in a suitable solvent and the percentage of free phenol is determined using phenol-free m-cresol as an internal standard. The gas chromatograph is fitted with a capillary column and a flame ionization detector (FID).

Drop point for stearates and waxes

ASTM D 3954 Standard: Method for determining the temperature at which wax suspended in a cylindrical cone with a 2.8 mm diameter hole in the bottom flows a distance of 19 mm and breaks a light beam. The wax is heated at a constant temperature gradient.

 
 

Martens degree of deformation

UNE 53026 Standard: Method for measuring, under specified conditions, the temperature at which a test specimen under a determined flexion force is displaced a pre-established distance.

Water absorption

ISO 62 Standard: Method for determining the water absorbed when a moulded test sample of a moulding compound is submerged in water at room temperature and at 100°C.

Transfer flow of a moulding compound

ISO 7808 Standard: Method for determining the fluidity of a moulding compound by pressing it in a standard mould under controlled conditions of pressure and temperature.

Granulometric analysis of powdered additives and loads

Method for determining the percentage of material retained in a sieve. The test material is placed on a sieve and subjected to a vacuum of 2.5 kPa.

Softening point of resins

ASTM D 3461 Standard: Method for determining the softening point of resins at a range of 50 to 180 °C. The resin is placed in a cylindrical cone with a 7.77 mm diameter hole in the bottom. A measurement is taken of the temperature at which the resin flows a distance of 19 mm and breaks a light beam. The resin is heated at a constant gradient of 2°C / min.

Percentage water content using Karl-Fisher methods

ISO 760 Standard: The method is based on the reaction of the water present in moulding compounds placed in a methanol solution of iodine and sulphur dioxide.

Apparent density of moulding compounds

UNE-EN-ISO 60 and UNE 53015 (II) Standards: Method for determining the weight of the moulding compound that fills a 100 ml capacity cylinder.

Charpy impact properties

UNE-EN-ISO 179 Standard: Method for determining the impact strength of a test specimen moulded from a moulding compound using a pendulum with a specific weight and period.

Post-moulding shrinkage of a moulding compound

ISO 2577 Standard: Method for determining the shrinkage of a standard test specimen after moulding under controlled pressure and temperature conditions. The determination is made using a micrometre after allowing the moulded test sample to stand for 16 hours at 23 ± 2°C and 45-55% relative humidity.

Density of a moulded product

ASTM D 792 Standard: Method for determining the density of a test specimen by calculating its mass in air and when immersed in water.
