🔬 Scope and Significance of D6159-23 ASTM D6159-23 specifies a test method for identifying and measuring hydrocarbon impurities in high-purity ethylene using gas chromatography. It targets critical impurities such as methane, ethane, propane, propene, acetylene, iso-butane, propadiene, butane, trans-2-butene, butene-1,…
ASTM D6157 – 97 (Reapproved 2024) establishes a standardized testing practice for determining the performance of oil/water separators when challenged by a sudden, large-volume release of hydrocarbons. This protocol provides a repeatable methodology for evaluating separator efficiency under shock loading…
ASTM D6158-23 defines the requirements for mineral and synthetic hydraulic oils corresponding to API Groups I through IV. This specification establishes a classification system that ensures reliable performance in hydraulic systems by categorizing fluids based on their additive chemistry and…
📐 Scope and Application This practice specifies the requirements for defining, testing, and verifying the performance of reversed-phase high performance liquid chromatographic (HPLC) systems for trace analysis of pesticides and toxic substances. It is applicable to pollution control programs and…
ASTM D6155-19 specifies the requirements for coarse aggregates that are not traditionally used in asphalt paving mixtures. These nontraditional aggregates are defined as any aggregate other than those covered by specifications D692/D692M, D693, D1139/D1139M, and D5106, which include crushed stone,…
🛠️ Materials and Manufacture According to Section 3 of D6154-15, the base asphalt cement used for chemical modification must be produced by refining crude petroleum through suitable methods. The chemical modification typically involves adding a chemical gellant or stabilizer, though…
ASTM D6152/D6152M – 12 (Reapproved 2024) defines the material specification for SEBS (styrene-ethylene-butylene-styrene) modified asphalt used primarily as a mopping grade material in built-up roof (BUR) construction, modified bitumen systems, vapor retarder systems, and for adhering insulation boards. This standard…
📐 Classification and Types of Membrane Systems ASTM D6153-23 specifies bridge deck waterproofing membrane systems for use with asphaltic concrete overlays. The standard covers three types of systems, each designed to prevent water passage from the asphalt surface course to…
Designation: D6151/D6151M −15 — Standard Practice for Using Hollow-Stem Augers for Geotechnical Exploration and Soil Sampling. This standard provides the authoritative framework for obtaining soil samples using Hollow-Stem Auger (HSA) systems, specifically focusing on geotechnical exploration and the retrieval of…
The ASTM D6150-24 standard, officially titled Standard Test Method for Estimating Processing Losses of Plastisols and Organosols Due to Volatility, provides a definitive laboratory procedure for measuring the relative volatility of PVC plastisols and organosols under controlled elevated temperature conditions.…
