Occupations | Performs laboratory tests according to prescribed standards to determine chemical and physical characteristics or composition of solid, liquid, or gaseous materials for such purposes as quality control, process control, or product development: Sets up, adjusts and operates laboratory equipment and instruments, such as microscopes, centrifuge, agitators, viscosimeter, chemical balance scales, spectrophotometer, gas chromatograph, colorimeter, and other equipment. Tests materials used as ingredients in adhesives, cement, propellants, lubricants, refractories, synthetic rubber, plastics, paint, paper, cloth, and other products for such qualities as purity, stability, viscosity, density, absorption, burning rate, and melting or flash point. Tests solutions used in processes, such as anodizing, waterproofing, cleaning, bleaching, and pickling for chemical concentration, specific gravity, or other characteristics. Tests materials for presence and content of elements or substances, such as hydrocarbons, manganese, natural grease, tungsten, sulfur, cyanide, ash, dust, or impurities. Tests samples of manufactured products to verify conformity to specifications. Records test results on standardized forms and writes test reports describing procedures used. Cleans and sterilizes laboratory equipment. May prepare graphs and charts. May prepare chemical solutions according to standard formulas. May add chemicals or raw materials to process solutions or product batches to correct or establish formulation required to meet specifications. May calibrate laboratory instruments. May be designated according to product or material tested. For testing of food products see FOOD TESTER (any industry) 029.361-014. (references) |
| Tests textile fibers and yarn at any stage in yarn-manufacturing process to determine conformance to standards: Collects samples from machines, gathers samples from carts, or receives samples at work station. Records information regarding samples on company forms, and identifies samples with tags prior to testing. Computes twists per inch in yarn samples, using formula and readings from twist counter. Feeds yarn, roving, or sliver into evenness tester that detects and records variations in weight on printout sheet. Winds specified length of yarn onto skein winder and removes skeins from winder. Weighs skeins of yarn on balance scale and obtains yarn number (measure of fineness) from dial or chart. Breaks individual strands or skeins of yarn with break tester to determine strength of yarn. Winds yarn on black panel for inspection, compares evenness and number of slubs and neps in yarn with standard photographs, and assigns grade. Weighs fiber sample on balance scale before and after drying and determines percentage of water content (moisture regain) by computation or by consulting chart. Records results of tests, compares results with company standards, and reports variations from standards to lab supervisor or MANAGER, QUALITY CONTROL (profess. & kin.) 012.167-014. Records waste produced by departments. May receive defective yarn returned by customer and test yarn to determine whether company purchased defective materials, defects occurred during company processing, or customer caused defects to occur. May perform standardized chemical tests to determine amount of oil or size in yarn. May be designated according to specialty as Yarn-Weight-And-Strength Tester (textile). (references) | |
| Tests and analyzes samples of crude oil and petroleum products during processing stages, using laboratory apparatus, testing equipment, and following standard test procedures to determine physical and chemical properties and ensure products meet quality control standards: Tests samples of crude and blended oils, gases, asphalts, and pressure distillates to determine characteristics, such as boiling, vapor, freeze, condensation, flash and aniline points, viscosity, specific gravity, penetration, doctor solution, distillation, and corrosion, using test and laboratory equipment, such as hydrometers, fractionators, distillation apparatus, and analytical scales. Analyzes content of products to determine presence of gases, such as propane, iso-butane, butane, iso-pentane, and ethene. Determines hydrocarbon composition of gasolines, blending stocks and gases, using fractional distillation equipment, gas chromatography, and mass spectrometer. Operates fractionation column to separate crude oil into oils with different boiling points to determine their properties. Analyzes composition of products to determine quantitative presence of gum, sulfur, aromatics, olefins, water, and sediment. Compares color of liquid product with charts to determine processing factors measurable by color. May test air and water samples to detect industrial pollutants. (references) | |
| Examines, measures, photographs, and tests synthetic fiber samples to facilitate quality control of forming, treating, and texturing processes, performing any combination of following tasks: Dips several twisted threads in melted wax and directs stream of cold water over threads to congeal wax. Slices threads crosswise, using microtome. Dissolves wax, using solvent, and positions thread sample on microscope slide. Inserts slide in microscope and photographs sample, using standard microphotographic equipment and techniques. Develops, prints, and labels photographs. Analyzes photographs to determine whether structure and other characteristics of thread meet plant standards. Determines tensile strength of thread samples, using device that draws material between two jaws until breakage occurs. Measures cross-sectional area of thread samples, using planimeter. Immerses samples in water, corrosives, or cleaning agents to detect shrinkage or damage. Places thread samples in dye bath to evaluate permeability of dye and exposes samples to controlled light source to ascertain fade resistance. Prepares and submits reports of findings to production personnel to facilitate quality control of product. (references) | |
