ASTM E2014-17 Standard Guide on Metallographic Laboratory Safety Active 发布日期 :  1970-01-01 实施日期 : 

4.1 This guide is intended as a summary of safety practices in the metallography laboratory. It can be used as a training reference for those new to the field of metallography and as a refresher to those who are experienced.4.2 This guide is not intended to be inclusive of all safety concerns encountered in a metallographic laboratory. Several books that provide safety information are available (1-15).54.3 Before operating any equipment, it is advisable to read and understand the accompanying manuals and to follow any specified safety guidelines.4.4 Safety data sheets (SDS) for chemicals being used in a laboratory should be on file and readily accessible. When working with any chemicals, especially for the first time, one should review the SDS supplied by the manufacturer and follow any safety guidelines suggested. The most current and applicable SDS should be on file for a given product or chemical.1.1 This guide outlines the basic safety guidelines to be used in a metallographic laboratory. Safe working habits are discussed for various tasks performed in a metallographic laboratory.1.2 The sections appear in the following order:  Section 1Referenced Documents 2Terminology 3 4General 5Heat Treating 6Specimen Preparation/Sectioning 7Specimen Mounting 8Mechanical Grinding/Polishing 9Chemical Safety 10Electrolytic Polishing/Etching 11Sulfur Printing 12Laboratory Ventilation/Fume Hoods 13Chemical Spills 14Photography 15X ray/Electron Microscopy 16Laboratory Ergonomics 17Disposal of Residues 18Keywords 191.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Differential scanning calorimetry provides a rapid method for determining the transformation temperature(s) of nickel-titanium shape memory alloys.5.2 This test method uses small, stress-free, annealed samples to determine whether a sample of nickel-titanium alloy containing nominally 54.5 to 57.0 % nickel by weight is austenitic or martensitic at a particular temperature. Since chemical analysis of these alloys does not have sufficient precision to determine the transformation temperature by measuring the nickel-to-titanium ratio of the alloy, direct measurement of the transformation temperature of an annealed sample of known thermal history is recommended.5.3 This test method is useful for quality control, specification acceptance, and research.5.4 Transformation temperatures derived from differential scanning calorimetry (DSC) may not agree with those obtained by other test methods due to the effects of strain and load on the transformation. For example, transformation temperatures measured in accordance with Test Method F2082 will differ from those measured by the current standard.5.5 The use of this test method for finished or semi-finished components without annealing (as in 8.2) shall be agreed upon between the purchaser and the supplier.1.1 This test method defines procedures for determining the transformation temperatures of nickel-titanium shape memory alloys, produced in accordance with Specification F2063, by differential scanning calorimetry.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and to determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Volatility of a material is not an equilibrium thermodynamic property but is a characteristic of a material related to a thermodynamic property that is vapor pressure. It is influenced by such factors as surface area, temperature, particle size, and purge gas flow rate; that is, it is diffusion controlled.5.2 The extent of containment achieved for specimens in these test methods by means of a pinhole opening between 0.33 mm to 0.38 mm allows for measurement circumstances that are relatively insensitive to experimental variables other than temperature. Decreasing the extent of containment by use of pinholes larger than 0.38 mm will increase the magnitude of the observed rate of mass loss but will also reduce the measurement precision by increasing the sensitivity to variations in other experimental variables.5.3 Results obtained by these test methods are not strictly equivalent to those experienced in processing or handling conditions but may be used to rank materials for their volatility in such circumstances. Therefore, the volatility rates determined by these test methods should be considered as index values only.5.4 The volatility rate may be used to estimate such quantifiable values as drying interval or the extent of volatile release from a process.1.1 These test methods cover procedures for assessing the volatility of solids and liquids at given temperatures using thermogravimetry under prescribed experimental conditions. Results of these test methods are obtained as volatility rates expressed as mass per unit time. Rates ≥5 μg/min are achievable with these test methods.1.2 Temperatures typical for these test methods are within the range from 25 °C to 500 °C. This temperature range may differ depending upon the instrumentation used.1.3 These test methods are intended to provide a value for the volatility rate of a sample using a thermogravimetric analysis measurement on a single representative specimen. It is the responsibility of the user of these test methods to determine the need for and the number of repetitive measurements on fresh specimens necessary to satisfy end use requirements.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 The information provided in this standard guide is intended for use by designers and specifiers of siphonic roof drainage systems and their related components. Specifically, this guide addresses the use and limitations of plastic pipe and fittings in siphonic roof drainage systems where internal operating pressures are typically sub-atmospheric.1.1 This guide covers design and installation considerations for plastic siphonic roof drain systems for industrial, commercial, public, and residential buildings. Requirements for materials, pipe, and fittings are included.1.2 The interchangeability of pipe and fittings made by different manufacturers is not addressed in this guide. Transition fittings for joining pipe and fittings of different manufacturers is provided for in the referenced pipe and fitting specification.1.3 In referee decisions, the SI units shall be used for metric-sized pipe and inch-pound units for pipe sized in the IPS system (ANSI B36.10). In all cases, the values given in parentheses are for information only.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
