Standard Test Method for Determining the Stability of Compost by Measuring Oxygen Consumption
5.1x00a0;This test method is used to evaluate oxidation stability of lubricating base oils with additives in the presence of chemistries similar to those found in gasoline engine service. Test results on some ASTM reference oils have been found to correlate with sequence IIID engine test results in hours for a 3758201;% viscosity increase.5 The test does not constitute a substitute for engine testing, which measures wear, oxidation stability, volatility, and deposit control characteristics of lubricants. Properly interpreted, the test may provide input on the oxidation stability of lubricants under simulated engine chemistry. 5.2x00a0;This test method is intended to be used as a bench screening test and quality control tool for lubricating base oil manufacturing, especially for re-refined lubricating base oils. This test method is useful for quality control of oxidation stability of re-refined oils from batch to batch. 5.3x00a0;This test method is useful for screening formulated oils prior to engine tests. Within similar additive chemistry and base oil types, the ranking of oils in this test appears to be predictive of ranking in engine tests. When oils having completely different additive chemistry or base oil type are compared, oxidation stability results may not reflect the actual engine test result. 5.4x00a0;Other oxidation stability test methods have demonstrated that soluble metal catalyst supplies are very inconsistent and they have significant effects on the test results. Thus, for test comparisons, the same source and same batch of metal naphthenates shall be used. Note 2:x00a0;It is also recommended as a good research practice not to use different batches of the fuel component in test comparisons. 1.1x00a0;This test method evaluates the oxidation stability of engine oils for gasoline automotive engines. This test, run at 1608201;x00b0;C, utilizes a high pressure reactor pressurized with oxygen along with a metal catalyst package, a fuel catalyst, and water in a partial simulation of the conditions to which an oil may be subjected in a gasoline combustion engine. This test method can be used for engine oils with viscosity in the range from 48201;mm2/s (cSt) to 218201;mm2/s (cSt) at 1008201;x00b0;C, including re-refined oils. 1.2x00a0;This test method is not a substitute for the engine testing of an engine oil in established engine tests, such as Sequence IIID. 1.3x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1x00a0;Exceptionx2014;Pressure units are provided in psig, and dimensions are provided in inches in Annex A1, because these are the industry accepted standard and the apparatus is built according to the figures shown. 1.4x00a0;This standard d......

Standard Test Method for Determining the Stability of Compost by Measuring Oxygen Consumption
This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus. Quantitative heat release measurements provide information that can be used for upholstery and mattress product designs and product development. Heat release measurements provide useful information for product development by yielding a quantitative measure of specific changes in fire performance caused by component and composite modifications. Heat release data from this test method will not be predictive of product behavior if the product does not spread flame over its surface under the fire exposure conditions of interest. Test Limitations8212;The test data are invalid if either of the following conditions occur: (1) explosive spalling; or (2) the specimen swells sufficiently prior to ignition to touch the spark plug, or the specimen swells up to the plane of the heater base during combustion.1.1 This fire-test-response test method can be used to determine the ignitability and heat release from the composites of contract, institutional, or high-risk occupancy upholstered furniture or mattresses using a bench scale oxygen consumption calorimeter. 1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant initial test heat flux of 35 kW/m2. This test method is also suitable to obtain heat release data at different heating fluxes. The specimen is oriented horizontally, and a spark ignition source is used. 1.3 The times to sustained flaming, heat release, and effective heat of combustion are determined using the apparatus and procedures described in Test Method E1354. 1.4 The tests are performed on bench-scale specimens combining the furniture or mattress outer layer components. Frame elements are not included. 1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 1.7 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. For specific precautionary statements, see Section 6.

This test method is not applicable to end-use products that do not have planar, or nearly planar, external surfaces.1.1 This fire-test-response standard provides for measuring the response of materials exposed to controlled levels of radiant heating with or without an external ignitor. 1.2 This test method is used to determine the ignitability, heat release rates, mass loss rates, effective heat of combustion, and visible smoke development of materials and products. 1.3 The rate of heat release is determined by measurement of the oxygen consumption as determined by the oxygen concentration and the flow rate in the exhaust product stream. The effective heat of combustion is determined from a concomitant measurement of specimen mass loss rate, in combination with the heat release rate. Smoke development is measured by obscuration of light by the combustion product stream. 1.4 Specimens shall be exposed to initial test heat fluxes in the range of 0 to 100 kW/m2. External ignition, when used, shall be by electric spark. The value of the initial test heat flux and the use of external ignition are to be as specified in the relevant material or performance standard (see X1.2). The normal specimen testing orientation is horizontal, independent of whether the end-use application involves a horizontal or a vertical orientation. The apparatus also contains provisions for vertical orientation testing; this is used for exploratory or diagnostic studies only. 1.5 Ignitability is determined as a measurement of time from initial exposure to time of sustained flaming. 1.6 This test method has been developed for use for material and product evaluations, mathematical modeling, design purposes, or development and research. Examples of material specimens include portions of an end-use product or the various components used in the end-use product. 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use.

本标准规定了用高锰酸钾氧化法测定水中的化学耗氧量。 本标准适用于煤矿工业用水、生活用水、地表水和地下水中化学耗氧量的测定，其测定范围为0.5~4.0 mg/L。
Diese ?NORM beschreibt eine Methode für das Absch?tzen der Hemmwirkung eines Untersuchungsmaterials auf den Sauerstoffverbrauch der Mikroorganismen im Belebtschlamm. Die Hemmwirkung kann die Wirkung sowohl auf die Atmung als auch auf die Nitrifikation einschlie?en. Mit der Methode werden Informationen über hemmende oder stimulierende Wirkung des Untersuchungsmaterials auf die Mikroorganismen des Belebtschlammes nach kurzer Einwirkungszeit (bis zu 180 min) erhalten. Die Methode ist auf Stoffe, die unter den Untersuchungsbedingungen l?slich sind, anwendbar. Besondere Aufmerksamkeit ist bei jenen Stoffen notwendig, die in Wasser schlecht l?slich sind und die auf physikalisch-chemischem Weg Sauerstoff verbrauchen oder erzeugen. Im Anhang werden zwei Beispiele für die Anwendung angeführt. Methode A soll die Bedingungen in Oberfl?chenwasser wiederspiegeln, Methode B jene in biologischen Abwasser-Reinigungsanlagen. Die mit den beiden Verfahren erhaltenen Ergebnisse k?nnen sich voneinander unterscheiden. Es ist daher besonders wichtig, im Untersuchungsbericht die ausgew?hlte Methode zu beschreiben. Bei flüchtigen Stoffen ist m?glicherweise nur Methode A anwendbar. Diese Methode ist auch für die Untersuchung von Abwasser geeignet.

Determination De La Proprete Des Plumes Par L'Indice D'Oxygene
This standard is applicable to the determination of biochemical oxygen demand, BOD, of all types of water and dilutions thereof containing no substances interfering with the degradation of organic matter. The method covers a wide range of concentrations of oxygen consuming material. The lower determination limit is a BOD value of 2 mg/1 for an undiluted sample. Special tests are required to check the presence of interfering substances, see 10.2. Interferences from chlorine, sulphur dioxide, hydrogen sulphide and other volatile sulphides can be eliminated as instructed in 10.3 — 10.5. The interference from immediate oxygen demand (IDOD)? is diminished by waiting 15 min between the dilution and the oxygen determination. This standard is in principle based on the methods and reports given under References.
