BS EN ISO 3613:2021 pdf free.Metallic and other inorganic coatings一Chromate conversion coatings on zinc, cadmium, aluminium-zinc alloys and zinc- aluminium alloys一Test methods. In the case of a cadmium substrate, observe the appearance of the spot for 1 mm. The formation of a dark or black stain at least 5 s after the application of the test solution shall be deemed to indicate the presence of a colourless chromate conversion coating. Black stain formation after more than I mm can be indicative of the presence of supplementary coatings, such as wax or oil. For comparison purposes, test an untreated surface similarly. Untreated zinc and cadmium surfaces, or the surfaces that have been treated for the chromate conversion coating but do not have a continuous coating, will react with the lead acetate solution to form a black stain on the untreated or bare zinc and cadmium surfaces almost immediately, within 2 s to 5 Sb after the application of the test solution. No significance is to be placed upon any differences in the reaction time to black-spot formation between 1 mm and 3 mm on a zinc substrate, or between 5 s and 60 s on a cadmium substrate, with a colourless…

BS ISO 7870-8:2017 pdf free.Control charts Part 8: Charting techniques for short runs and small mixed batches. The business aim of statistical process control (SPC) is to control and improve quality, increase productivity and reduce cost. The principal graphical tool of SPC is the control chart. There arc three main classes of control charts: Shewhart, cumulative sum cusum) and exponentially weighted moving average (F.WMA). NOTE Cusum control charts are dealt with in ISO 7870.4 and EWMA in ISO 7870.6. The Shewhart control chart provides a graphical representation of a process showing plotted values of a representative statistic of a selected characteristic (for instance, the individual value, mean, range or standard deviation), a centre line, and one or more control lines. The control line(s) and centre line are used as a basis for judging the stability ol the process, namely, whether or not the process is in a state of statistical control. Control lines are derived from the actual performance of the process and are not to be confused with specified limits or specified tolerances. Shewhart control charts provide a common language for communicating technical information on the performance of a process. Control charts are effective tools in understanding process behaviour….

BS ISO 91:2017 pdf free.Petroleum and related products  – Temperature and pressure volume correction factors (petroleum measurement tables) and standard reference conditions. API MPMS Chapter 11.1-2004/Adjunct to ASTM D1250-04 and IP 200/04 provides general procedures for the conversion of input data to generate the corrected values at the user specified base temperature and pressure using the effect of temperature on the liquid (CTL), the compressibility coefficient (Fr), the correction for the effect of pressure on the liquid (CPL), or the correction for temperature and pressure of a liquid (CTPL), in a form that is consistent with the computation procedures used to generate VCF values. Two sets of procedures are given for computing the volume correction factor: one set for data expressed in U.S. customary units (temperature in degrees Fahrenheit, pressure in pounds per square inch gauge). the other for the metric system of units (temperature in degrees Celsius. pressure in kilopascals). In contrast to API MPMS Chapter 11.1-1980/ASTM D1250-80/IP 200/80, the metric procedures require the procedure for U.S. customary units be used first to compute density at 60 °F. This value is then further corrected to give the metric output. For density/weight/volume intraconversion, reference shall be made to API MPMS…

BS ISO 20759:2017 pdf free.Traditional Chinese medicine一Artemisia argyi leaf. The following requirements should be met before separating the bulk sample into test samples. a) Artermisia argyl leaf shall be clean and free from foreign matter. b) The presence of moldy leaves, external contaminants and living insects which are visible to the naked eye shall not be permitted. 5.2 Macroscopic characteristics The leaves are mostly crumpled or broken, with short petioles and usually without pseudostipule at the base. The leaf blade is broad ovate, rhombic-ovate, or ovate-elliptical, 5 cm to 9(16) cm long, 4 cm to 8(16) cm wide, and pinnatipartite to pinnatifId; segments in two or three pairs, elliptical-lanceolate, or elliptical-oblanceolate, frequently 1 cm to 1,5(3) cm wide, with margin irregularly dentate or lobed or wide serrate, dentate piece or wide sawtooth, mostly asymmetrically ovate-lanceolate, ovate-triangular, or entire. Smaller leaves are fewer, pinnatipartite, tn-cleft, and sometimes entire and elliptical to lanceolate. The upper surface is greyish-green or dark yellowish-green, possessing somewhat sparse pubescences, denser glandular dots and small pits; lower surface is covered densely with greyish-white tomenta. The petiole is usually 2 mm to 8 mm long, and up to 1,3 cm in the cultivated plants. It has a specific,…

BS EN ISO 5754:2017 pdf free.Sintered metal materials, excluding hardmetals一Unnotched impact test piece. This document specifies the dimensions of an unnotched impact test piece of sintered metal materials. The test piece may be obtained directly by pressing and sintering or by machining a sintered part. This document applies to all sintered metals and alloys, with the exception of hardmetals. However, for certain materials (for example, materials with low porosity or materials with high ductility), it may be more appropriate to use a notched test piece which, in this case, will give results with less scatter. (In this case, refer to ISO 148-1.) NOTE For porous sintered materials, the results obtained from impact tests are not necessarily very accurate compared with results obtained from tests on solid metals. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
