ISO 75-1-2020 pdf free.Plastics – Determination of temperature of deflection under load -Part 1:General test method. A standard test specimen is subjected to three-point bending under a constant load in the flatwise position to produce one of the flexural stresses given in the relevant part of ISO 75. The temperature is raised at a uniform rate, and the temperature at which the standard deflection, corresponding to the specified increase in flexural strain, occurs is measured. 5 Apparatus 5.1 Means of producing a flexural stress The apparatus shall be constructed essentially as shown in Figure 1. It consists of a rigid metal frame in which a rod shall move freely in the vertical direction. One end of the rod is fitted with a weight- carrying plate and the other end is equipped with a loading edge. The base of the frame is fitted with test-specimen supports. These supports and the vertical members of the frame are made of a material having the same coefficient of linear expansion as the rod. The test-specimen supports consist of metal pieces that are cylindrical in the contact area and with their lines of contact with the specimen in a horizontal plane. The size of the…

ISO 36-2020 pdf free.Rubber, vulcanized or thermoplastic—Determination of adhesion to textile fabrics. This document specifies a method of test for measuring the force required to separate, by stripping, two plies of fabric bonded with rubber, or a rubber layer and a fabric ply bonded together. The method is applicable when the ply surfaces are approximately plane or when they are in the form of a cylinder having an internal diameter greater than approximately 50 mm. The method is not applicable when the ply surfaces contain sharp bends, angles or other gross irregularities which cannot be excluded when cutting out test pieces. This document does not apply to coated fabrics, which are tested in accordance with ISO 2411, or textile conveyor belts, which are tested in accordance with ISO 252. 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.

BS ISO 20205:2015 pdf free.Space data and information transfer systems – Spacecraft Onboard Interface Systems Low Data-Rate Wireless Communications for Spacecraft Monitoring and Control. 2.1 RATIONALE ANI BENEFITS Monitoring and controlling the behavior of a spacecraft and launch systems. during testing phases on ground or during nominal operations in orbit, is the key to ensuring the correct functioning of various onboard systems and structures, the responses of these systems in their operational working environments, and the long-term reliability of the spacecraft. These data are also highly significant when compiling lessons learned that will be applied to building better space systems and increasing the reliability of future space components. (Refer to reference [3] for a comprehensive overview of application domains and for a detailed summary of RF communications and restrictions in differing operational environments.) The quantity of acquired spacecraft functional data depends on the ability to monitor required parameters at precise locations within a given project time and cost envelope. Hundreds and often thousands of data measurement locations are required. steadily increasing the mass (acquisition systems. cables, and harnesses) and the project costs and time (installation and verification of each new sensor). The use of wireless technologies is foreseen to reduce…

BS ISO 6621-5:2020 pdf free.Internal combustion engines一Piston rings Part 5: Quality requirements. This document specifies quality aspects that can be defined but that are not normally found on a drawing specification. It covers the following: — single-piece piston rings of grey cast iron or steel; — multi-piece piston rings (oil control rings) consisting of cast iron parts and spring components; and — single-piece and multi-piece oil control rings of steel, i.e. oil control rings in the form of strip steel components or steel segments (rails) with spring expander components. In addition to specifying some of the limits of acceptance relating to inspection measuring principles (covered by ISO 6621-2), this document also covers those features for which no recognized quantitative measurement procedures exist and which are only checked visually with normal eyesight (glasses if worn normally) and without magnification. Such features (superficial defects) are additional to the standard tolerances of ring width, radial wall thickness and closed gap. This document does not establish acceptable quality levels (AQL), it being left to manufacturer and customer to decide the appropriate levels jointly. In this case, the recommendations of ISO 2859-1 are followed. This document specifies the quality requirements of piston rings for reciprocating…

BS ISO 15727:2020 pdf free.UV-C devices一Measurement of the output of a UV-C lamp. This document specifies the measurement of the output of a UV-C lamp, types of UV-C lamp, lamp ballast, and safety issues. It is applicable to the output measurement of linear UV-C disinfection lamps. This document specifies a measurement method for evaluating output power of UV-C lamps installed in heating, ventilation and air conditioning (HVAC) systems. The method includes the simulation measurement of UV-C output power of UV-C lamps under various temperatures and various air velocities, and under conditions that the axial direction of the lamp is parallel or perpendicular to the air flow direction. It can reliably evaluate and compare the UV-C output power of UV-C lamps in the ultraviolet germicidal irradiation (UVGI) device based on the testing results. If the microbial inactivation rate of a particular UVGI device equipped with the same type of UV-C lamp is known, the microbial inactivation rate of the UVGI device at various temperatures and at various air velocities can be evaluated. 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.

If working with a water bath (see A) rather than a temperature-controlled chamber, put the pycnometer and the test sample in the water bath, maintained at the specified or agreed temperature. Allow approximately 30 mm for temperature equilibrium to be reached. Using the thermometer (), measure the temperature, tT, of the test sample. Check throughout the determination that the temperature of the chamber or water bath remains within the specified limits. Weigh the pycnometer and record the mass, ml, to the nearest 10 mg for 50 cm3 to 100 cm3 pycnometers and to the nearest 1 mg for pycnometers less than 50 cm3 in volume.
