Occupations | Determines physical properties of greige and finished cloth, employing standardized tests, equipment, and procedure: Measures width of cloth with ruler. Guides electric knife along markings on cloth to cut fabric samples for testing. Weighs sample on grain scales and converts grain weight into desired units, using mathematical tables. Counts number of warp and filling per unit space, using pick counter. Positions cloth sample between jaws of testing machine and moves machine controls to apply force necessary to rupture sample and determine tensile strength of cloth. Sews across sample, using portable sewing machine, and examines stitching through magnifying lens to detect threads broken by sewing machine needle. Creases sample under controlled conditions and places sample in clamp on crease recovery tester to determine cloth resiliency to creasing. Records test results and reports variation from standards to MANAGER, QUALITY CONTROL (profess. & kin.). In addition, may perform other tests, such as tear test, crimp test, fabric bow test, abrasion test, bursting test, heat transmission test, permeability test, and water repellency test.

| Performs standardized laboratory tests to verify chemical characteristics or composition of textile fibers, yarns, and products, and materials used in processing textiles: Tests oil and soap products to determine fitness for use in cloth and yarn finishing processes. Tests dyed goods for stripping (removing dye). Tests greige goods to determine if goods are of specified quality for dyeing, printing, and finishing. Verifies dye formulas used to develop or match colors by dyeing samples of cloth, yarn or textile fibers, and determines fastness of dyes, using laboratory equipment. Tests raw stock for moisture content with meter-equipped probe. Verifies efficiency of scouring process by testing wool samples to determine percentage of natural greases removed, using scales, solvents, and ovens. Measures tear strength and wet and dry tensile strength, using tensile-testing equipment. Determines color value by subjecting material to lights. Visually inspects yarns and finished material. May classify finished product according to quality and estimate amount of mending required. (references) | |
| Performs standardized physical and chemical tests on materials and supplies used throughout power system to ensure compliance with specifications: Tests water used in boilers of steam generating plant for alkalinity and silica and phosphate content, using colorimeter and spectrophotometer. Notifies POWER-PLANT OPERATOR (utilities) or AUXILIARY-EQUIPMENT OPERATOR (utilities) of amount of chemical additives required to bring water to prescribed level of purity. Tests coal to determine Btu content by burning coal samples in colorimeter. Tests oil used in circuit breakers for dielectric strength by placing sample of oil in ceramic cup positioned between two electrodes, and measuring current conducted by oil, using ohmmeter. Ascertains heat resisting qualities of insulating paints and varnishes by coating pieces of sheet metal with paint and varnish and subjecting them to high temperatures. May determine viscosity index of lubricating oils, using viscosimeter. May inspect rubber protective equipment, such as aprons, gloves, and blankets for flaws. (references) | |
| Cleans laboratory equipment, such as glassware, metal instruments, sinks, tables, and test panels, using solvents, brushes, and rags: Mixes water and detergents or acids in container to prepare cleaning solution according to specifications. Washes, rinses, and dries glassware and instruments, using water, acetone bath, and cloth or hot-air drier. Scrubs walls, floors, shelves, tables, and sinks, using cleaning solution and brush. May sterilize glassware and instruments, using autoclave. May fill tubes and bottles with specified solutions and apply identification labels. May label and file microscope slides. May arrange specimens and samples on trays to be placed in incubators and refrigerators. May deliver supplies and laboratory specimens to designated work areas, using handtruck. May tend still that supplies laboratory with distilled water. May be designated Glass Washer, Laboratory (any industry) when cleaning glassware. May maintain inventory reports and logs.

| Prepares samples of paper and paper products for filing and mailing, performing any combination of following tasks: Collects samples of paper from paper machines, coating machines, supercalenders and cutting machines. Cuts samples to specified dimensions, using paper cutter. Marks samples with identifying information, such as customer order number, batch number, and grade and color of paper, or pastes labels on samples. Files samples for use in tracing technical defects or to facilitate processing of repeat orders, mails samples to customers, or distributes them to plant officials for examination. May compare samples with standard or customer's sample to ascertain that paper meets specifications of grade and color. May send samples to laboratory for testing and compare test reports with specifications. May address packages of samples to be mailed to customers, by hand or using typewriter. (references) | |
| Performs routine tests in medical laboratory to provide data for use in diagnosis and treatment of disease: Conducts quantitative and qualitative chemical analyses of body fluids, such as blood, urine, and spinal fluid, under supervision of MEDICAL TECHNOLOGIST (medical ser.) 078.261-038. Performs blood counts, using microscope. Conducts blood tests for transfusion purposes. May draw blood from patient's finger, ear lobe, or vein, observing principles of asepsis to obtain blood samples. May specialize in hematology, blood bank, cytology, histology, or chemistry. (references) | |
| Tests sand, shale, and other earth materials to determine petroleum and mineral content and physical characteristics: Performs routine chemical or physical tests of earth samples in field or laboratory to determine content of hydrocarbon or other minerals indicating presence of petroleum and mineral deposits. Tests core samples brought up during well drilling to determine permeability and porosity of sample, fluid content of sand and shale, salinity of drilling mud, and other conditions affecting oil well drilling operations. (references) | |
| Performs duties according to type of research in which supervising scientist is engaged, such as collecting rock samples for study by GEOLOGIST (profess. & kin.) or plant specimens for study by BOTANIST (profess. & kin.). Prepares samples for analysis or examination and performs routine laboratory tests. May participate in field explorations, such as mineralogical or geophysical expeditions. May be designated according to field of scientific research. (references) | |
| Siphons human blood plasma into pooling bottles for processing or storage: Removes cap from donor bottle and punctures stopper with needle. Connects vacuum pump to donor and pool bottles, using sterile glass and rubber tubing. Opens vacuum valve to siphon plasma into pooling bottle. Draws off and labels sample from each pool bottle. May introduce sterile, compressed air into pool bottles to transfer plasma to individual containers. (references) | |
