ASTM Standards Interpretation
🧪 Scope and Summary of the Practice ASTM D5198-17 (Reapproved 2024) defines a standard practice for the partial digestion of solid waste using nitric acid. This method is designed specifically for the subsequent determination of total recoverable inorganic constituents. It…
ASTM D5197-21 establishes a standardized procedure for the determination of formaldehyde and other carbonyl compounds in air using active sampler methodology. This method is widely applied in indoor air quality investigations, industrial hygiene assessments, and environmental monitoring, functioning as a…
ASTM D5195−21 specifies a nuclear method for determining the in-place wet density of soil and rock at depths below the surface. This standard, under the jurisdiction of ASTM Committee D18, calculates the wet density by comparing the detected rate of…
🧪 Introduction and Scope of D5196-06 ASTM D5196-06 (Reapproved 2018) provides a comprehensive guide for the chemical, physical, and biological characteristics of water intended for critical laboratory bio-applications. This includes sensitive fields such as clinical analysis, pharmaceutical research, molecular biology,…
🧪 Scope and Principle of the Method Chloride contamination, even at trace levels, acts as a potent catalyst poison and can cause severe pitting corrosion in stainless steel equipment used for aromatic hydrocarbon processing. ASTM D5194‑24a provides the definitive wet…
📐 Specimen Requirements and Geometry According to ASTM D5193, three circular test specimens must be accurately cut from the coated fabric. Each specimen shall have a diameter of 330 ± 3 mm [13 ± 0.1 in.] and a thickness of…
⚗️ Scope and Applicability ASTM D5191-22 specifies the procedure for determining the total vapor pressure of volatile petroleum products and liquid fuels using automated instruments. It covers spark-ignition fuels with oxygenates and ethanol blends up to 85% (volume fraction). The…
The ASTM D5192/D5192M standard establishes the definitive practice for the collection and handling of coal samples derived from borehole cores. Following this procedure is critical for maintaining the in-situ integrity of the sample, ensuring that subsequent geological evaluation and laboratory…
📐 Scope and Definitions This test method covers the determination of the total vapor pressure of air-containing, volatile petroleum products with boiling points above 0°C (32°F). It is specified for samples exerting a vapor pressure between 7 and 172 kPa…
📐 Scope and Technical Requirements ASTM D519-04 (Reapproved 2013) defines the standard test method for measuring the average length and length distribution of fibers in wool top on a mass-biased basis. The method is applicable to all types of fibers…
📐 Scope and Significance This standard, designated ASTM D5187-21, establishes the procedure for determining the mean crystallite thickness (Lc) of calcined petroleum coke using X-ray diffraction. The crystallite size parameter Lc is a critical indicator of the coke’s heat treatment…
📐 Test Scope and Applicability ASTM D5188 −23 defines a standardized procedure for determining the temperature at which the vapor formed from an air-saturated, chilled sample produces a pressure of exactly 101.3 kPa (one atmosphere) against a vacuum. The method…
