1. Medical Laboratory Testing Equipment

Laboratory equipment standards, developed by ASTM, specify general laboratory apparatus such as lab ware and weighing devices. Products and Services / Standards & Publications / Standards Products ASTM's laboratory testing standards are instrumental in specifying the standard dimensions, design, and make of the various equipments. Concerned with electrical safety testing meth-ods. It focuses only on the tests and equipment needed to minimize electrical shock and does not discuss mechanical/physical injury and fire hazards. Electrical Shock Electrical shock and its effects can be caused and influenced by several factors. The primary effect is the result of electrical. 173 Material Safety Data Sheets for Chemicals..... 187 Page - 1 List of Possible Hazards in M.T.O.

Medical Laboratory Testing Equipment

Description APPLICATIONS For use in those applications where process materials can be heated by inserting heater into a 2' or larger pipe. A pipe union will facilitate installation and eliminate the need for twisting the elements inside the pipe. Clearance room should be considered.

FEATURES Choice of materials and surface loadings (W/in2) permit operating in the dead air space of pipes, tubes, or channels. CAUTION AND WARNING! Fire and electrical shock may result if products are used improperly or installed or used by non-qualified personnel. See inside back cover for additional warning.

0.If equipment for test # LS 619 is not available, the magnesium sulphate soundness test is acceptable, as detailed in LS 606, providing the weighted average loss is a maximum of: HL 1 and 3.16% HL 2, 4 and 8. 20% Material Passing the 75 µm Sieve: In any fine aggregate, not more than 20 percent of the material passing the 75 µm sieve shall be finer than 2 µm in size. 1003.05.03Coarse Aggregate 1003.05.03.01Gradation Requirements Coarse aggregate shall be consistently graded and shall meet the gradation requirements shown in Table 3. The gradation envelope represents the extreme limits.

The gradation shall be reasonably consistent and not subject to the extreme percentages of gradation specified in Table 3. 0 - 10.MTO Lab Test No. 1003.05.03.02Physical Requirements Coarse aggregate for HL 1 shall conform to Table 4. Coarse aggregate for HL 3, 4 and 8 shall conform to Table 5.

1003.05.04Filler Filler shall consist of mineral filler, hydrated lime, Portland cement, or other material as designated and currently approved by the Owner for use in asphaltic concrete. Mineral filler shall consist of thoroughly dry dust produced from rock sources acceptable for coarse aggregates approved under physical requirements listed in Table 4, and shall meet the following gradation requirements: Passing 600 µm Sieve.100% Passing 75 µm Sieve - not less than.80%. 60.When quarried rock is used as a source of coarse aggregate, a maximum of 2 percent passing the 75 µm sieve shall be permitted. 1003.07PRODUCTION 1003.07.01Aggregate Processing, Handling and Stockpiling A minimum of three days notice shall be given by the Contractor to the Contract Administrator prior to stockpiling aggregate at the asphalt plant site.

The processed aggregates shall be separated into fine aggregate and coarse aggregate which shall be stockpiled separately. Aggregates separated during processing, aggregates secured from different sources, and aggregates from the same source but of different gradations shall be placed in individual stockpiles. Where screenings from primary and secondary crushers are produced separately, they shall be stockpiled separately.

Aggregates which have become mixed with foreign matter of any description or aggregates which have become mixed with each other shall not be used and shall be removed from the stockpile immediately. When a change in the character of the materials occurs or when the performance of the materials is found to be unsatisfactory, use of the materials shall be discontinued until a reappraisal by the Owner proves the source to be satisfactory. 1003.08QUALITY ASSURANCE 1003.08.01Sampling and Testing of Aggregate Sources The Contract Administrator may sample and test the aggregates from the proposed sources.
