Executive Summary: Over the past decade, the use of consultants by state transportation agencies has increased significantly. In recognition, AASHTO has seen a need to conduct a study, to develop this guide that discusses findings and presents methods, procedures, and suggested recommendations for...
Includes: CAG19 instantaneous overcurrent and earth fault relays
1.1 This practice covers the sampling of air for a variety of common pesticides and polychlorinated biphenyls (PCBs) and provides guidance on the selection of appropriate analytical measurement methods. Other compounds such as polychlorinated dibenzodioxins/furan
1.1 This test method is used to identify and to measure the emissions of volatile organic compounds (VOCs) emitted from samples of cured spray polyurethane foam (SPF) insulation using micro-scale environmental test chambers combined with specific air sampling and analytical methods for VOCs. 1.2...
1.1 This test method covers a standard procedure for the determination of hydrocarbon types (saturates, olefins, styrenes, aromatics and polyaromatics) of waste plastic process oil (WPPO) from chemical or thermal processes using gas chromatography and vacuum ultraviolet absorption spectroscopy...
5.1 Identification and Quantification of Phthalates-DBP, BBP, DEHP, DNOP, DINP and DIDP are representative of the phthalates either banned or being monitored by a variety of regulations. Regulations include: EU-Directive 2005/84/EC, US-Consumer Product Safety Improvement Act of 2008 - section 108,...
This specification covers cumene (isopropylbenzene) manufactured via a zeolite catalyst process. Cumene shall conform to the following requirements: purity weight percent, alpha-methylstrene, benzene, cumene hydroperoxide, diisopropylbenzenes,
1.1 This test method covers the determination of the boiling point distribution and cut point intervals of crude oils and residues by using high temperature gas chromatography. The amount of residue (or sample recovery) is determined using an external standard. 1.2 This test method extends the...
5.1 This test method is intended to measure volatile extractables that may be emitted from a microwave susceptor material during use. It may be a useful procedure to assist in minimizing the amount of volatile extractables either through susceptor design or manufacturing processes. 5.2 Modification...
1.1 This test method covers determination of the amount of residual solvents released from within a packaging material contained in a sealed vial under a given set of time and temperature conditions and is a recommended alternative for Test Method F151. 1.2 This test method covers a procedure for...
1.1 This test method covers a gas chromatographic procedure for the determination of the ppm residual acetaldehyde (AA) present in poly(ethylene terephthalate) (PET) homo-polymers and co-polymers which are used in the manufacture of beverage bottles. This includes sample types of both amorphous and...
