ASTM D4226
ASTM D4226 – Standard Test Methods for Impact Resistance of Rigid Poly(Vinyl Chloride) (PVC) Building Products Description: Significance and Use 5.1 The impact strength values obtained on the flat sections of a building product profile are relevant only to the flat section that has been tested and these values do not necessarily indicate the impact resistance …
ASTM D4222
ASTM D4222 – Standard Test Method for Determination of Nitrogen Adsorption and Desorption Isotherms of Catalysts and Catalyst Carriers by Static Volumetric Measurements Description: Significance and Use 5.1 The test method has two main functions: first, it provides data useful for establishing the pore size distribution of catalyst materials, which in turn may influence their performance; …
ASTM D4221
ASTM D4221 – Standard Test Method for Dispersive Characteristics of Clay Soil by Double Hydrometer Description: Significance and Use 5.1 Dispersive clays are those which normally deflocculate when exposed to water of low-salt concentration, the opposite of aggregated clays that would remain flocculated in the same soil-water system (3, 4, 7). Generally, dispersive clays are highly erosive, possibly subject …
ASTM D422
ASTM D422 – Standard Test Method for Particle-Size Analysis of Soils (Withdrawn 2016) Description: Abstract This test method covers the quantitative determination of the distribution of particle sizes in soils. The distribution of particle sizes larger than 75 micrometers (retained on the No. 200 sieve) is determined by sieving, while the distribution of particle sizes …
ASTM D4218
ASTM D4218 – Standard Test Method for Determination of Carbon Black Content in Polyethylene Compounds by the Muffle-Furnace Technique Description: Significance and Use 5.1 This test method is capable of yielding duplicate test data, in 20 min or less, for a simple carbon black content determination. 5.2 This test method is suitable for manufacturing quality control, technical …
ASTM D4214
ASTM D4214 – Standard Test Methods for Evaluating the Degree of Chalking of Exterior Paint Films Description: Significance and Use 4.1 The procedures provide a broad range of techniques and photographic references to evaluate chalking of exterior paints. Scope 1.1 These test methods cover the evaluation of the degree of chalking on white or tinted exterior paint …
ASTM D4213
ASTM D4213 – Standard Test Method for Scrub Resistance of Paints by Abrasion Weight Loss Description: Significance and Use 4.1 Interior paint films often become soiled, especially near doorways, windows, and play areas, and frequently need to be cleaned by scrubbing. This test method covers the determination of the relative resistance of paints to erosion when …
ASTM D4212
ASTM D4212 – Standard Test Method for Viscosity by Dip-Type Viscosity Cups Description: Significance and Use 5.1 Viscosity is a measure of the fluidity of a material. Viscosity data are useful in the determination of the ease of stirring, pumping, dip coating, or other flow-related properties of paints and related fluids. 5.2 This type of cup is …
ASTM D421
ASTM D421 – Standard Practice for Dry Preparation of Soil Samples for Particle-Size Analysis and Determination of Soil Constants (Withdrawn 2016) Description: Significance and Use This practice can be used to prepare samples for particle-size and plasticity tests where it is desired to determine test values on air-dried samples, or where it is known that …
