简介:This part of ISO 15927 specifies two procedures for providing an estimate of the quantity of water likely toimpact on a wall of any given orientation. It takes account of topography, local sheltering and the type ofbuilding and wall.The first method, given in Clause 3 and based on coincident hourly rainfall and wind data, defines a means ofcalculating-- the annual average index, which influences the moisture content of an absorbent surface, such as masonry, and-- the spell index, which influences the likelihood of rain penetration through masonry and joints in other walling systems.The second method, given in Clause 4 and based on average wind data and a qualitative recording of thepresence and intensity of rain (the present weather code for rain), defines a means of calculating the spelllength during which an absorbent material such as masonry is moistened, which has a 10 % probability ofbeing exceeded in any year (commonly referred to as having a mean return period of 10 years).A comparison between the two methods is given in informative Annex D.Procedures are given to correct the results of both methods for topography, local sheltering and the type ofbuilding and wall.The methods included in this part of ISO 15927 do not apply ina) mountainous areas with sheer cliffs or deep gorges,b) areas in which more than 25 % of the annual rainfall comes from severe convective storms,c) areas and periods when a significant proportion of precipitation is made up of snow or hail.

ASTM E1960-2007(2011) 计算铺筑表面的国际摩擦指数的标准操作规程
简介:This is the practice for calculating the IFI of the pavement. The IFI has proven useful for harmonization of the friction measuring equipment. F60 and Sp have proven to be able to predict the speed dependence of wet pavementx2013;related measurements of the various types of friction-measuring equipment. The two IFI parameters (F60 and Sp) have been found to be reliable predictors of the dependence of wet pavement friction on tire slip and vehicle speed. The IFI parameters, F60 and Sp, can be used to calculate the calibrated friction at anotherx2013;slip speed using a transformation equation. The IFI model given below describes the relationship between the values of wet pavement friction FRS measured at a slip speed of S and between the friction values measured by different types of equipment. A significance of the IFI Model is that the measurement of friction with a device does not have to be at one of the speeds run in the experiment. FRS can be measured at some S and is always adjusted to FR60. Thus, if a device can not maintain its normal operating speed and must run at some speed higher or lower because of traffic, the model still works well. In that case S is determined by the vehicle speed (V) which can be converted to S by multiplying V by the percent slip for fixed slip equipment or by multiplying V by the sine of the slip angle for side force equipment. This practice does not address the problems associated with obtaining a measured friction or measured macrotexture.1.1 This practice covers the calculation of the International Friction Index (IFI) from a measurement of pavement macrotexture and wet pavement friction. The IFI was developed in the PIARC International Experiment to Compare and Harmonize Texture and Skid Resistance Measurements. The index allows for the harmonizing of friction measurements with different equipment to a common calibrated index. This practice provides for harmonization of friction reporting for devices that use a smooth tread test tire. 1.2 The IFI consists of two parameters that report the calibrated wet friction at 60 km/h (F60) and the speed constant of wet pavement friction (Sp). 1.3 The mean profile depth (MPD) has been shown to be useful in predicting the speed constant (gradient) of wet pavement friction. 1.4 A linear transformation of the estimated friction at 60 km/h provides the calibrated F60 value. The estimated friction at 60 km/h is obtained by using the speed constant to calculate the estimated friction at 60 km/h from a measurement made at any speed. 1.5 The values stated in SI (metric) units are to be regarded as standard. The inchx2013;pound equivalents are rationalized, rather than exact mathematical conversions. 1.6 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.

BS ISO 6336-2-2006 正齿轮和斜齿轮承载能力的计算.表面耐久性的计算(针点)
简介:This part of ISO 6336 specifies the fundamental formulae for use in the determination of the surface load capacity of cylindrical gears with involute external or internal teeth. It includes formulae for all influences on surface durability for which quantitative assessments can be made. It applies primarily to oil-lubricated transmissions, but can also be used to obtain approximate values for (slow-running) grease-lubricated transmissions, as long as sufficient lubricant is present in the mesh at all times. The given formulae are valid for cylindrical gears with tooth profiles in accordance with the basic rack standardized in ISO 53. They may also be used for teeth conjugate to other basic racks where the actual transverse contact ratio is less than s^ = 2,5. The results are in good agreement with other methods for the range, as indicated in the scope of ISO 6336-1. These formulas cannot be directly applied for the assessment of types of gear tooth surface damage such as plastic yielding, scratching, scuffing or any other than that described in Clause 4. The load capacity determined by way of the permissible contact stress is called the "surface load capacity" or "surface durability".

简介:This European Standard specifies the boundary conditions and the prove methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature. This standard shall be applied to commercial trade and practical engineering if proved and certifiable values of the thermal output shall be used. This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This Part of this European Standard applies to hot water floor heating systems. Applying of Part 5 of this European Standard requires the prior use of this Part of this European Standard. Part 5 of this European Standard deals with the conversion of the thermal output of floor heating systems determined in Part 2 into the thermal output of heating surfaces embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings. The thermal output is proved by a calculation method (Clause 6) and by a test method (Clause 9). The calculation method is applicable to systems corresponding to the definitions in EN 1264-1 (type A, type B, type C, type D). For systems not corresponding to these definitions, the test method shall be used. The calculation method and the test method are consistent with each other and provide correlating and adequate prove results. The prove results, expressed depending on further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference between the heating medium and the room.

ASTM E1980-2011 计算水平和低斜度无光泽表面太阳反射光指数的标准操作规程
简介:Solar reflectance and thermal emittance are important factors affecting surface and near-surface ambient air temperature. Surfaces with low solar reflectance, absorb a high fraction of the incoming solar energy. A fraction of this absorbed energy is conducted into ground and buildings, a fraction is convected to air (leading to higher air temperatures), and a fraction is radiated to the sky. For equivalent conditions, the lower the emissivity of a surface the higher its steady-state temperature. Surfaces with low emissivity cannot effectively radiate to the sky and, therefore, get hot. Determination of solar reflectance and thermal emittance, and subsequent calculation of the relative temperature of the surfaces with respect to black and white reference temperature (defined as Solar Reflectance Index, SRI), may help designers and consumers to choose the proper materials to make their buildings and communities energy efficient. The method described here gives the SRI of surfaces based on measured solar reflectances and thermal emissivities of the surfaces.1.1 This practice covers the calculation of the Solar Reflectance Index (SRI) of horizontal and low-sloped opaque surfaces at standard conditions. The method is intended to calculate SRI for surfaces with emissivity greater than 0.1. 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 and health practices and determine the applicability of regulatory limitations prior to use.
