A stable and reliable pressure circuit is essential for accurate long-term hydrostatic pressure testing of plastic pipes and fittings. AHP PLASTIK MAKINA has developed a new 4-liter diaphragm accumulator specifically for use in hydrostatic pressure testing systems. The accumulator is designed to help stabilize system pressure, absorb pressure fluctuations, reduce hydraulic pulsations, and protect pressure…
SAFETY INSTRUCTIONS Due to the potential hazards associated with any electrical instrument, it is important that the user is familiar with the instructions covering the capabilities and the operation of the instrument. The user should ensure that all reasonable safety precautions are followed and if any doubt, should seek professional advice before proceeding. The instrument…
1. Purpose and Scope BS 5852:1990 describes laboratory methods for assessing the ignitability of upholstered seating material combinations and complete items of seating when exposed to smouldering and flaming ignition sources. The test programme is intended to represent a stepped range of accidental ignition severities rather than a continuous fire-performance scale. The standard distinguishes between…

10 Method E6: Repeated bending10.1 ObjectThe purpose of this test is to determine the ability of an optical fibre cable to withstand repeated bending.Repeated bending of connectorized optical fibre cable involves testing as a unit, testing both the capabilities of the cable and the connector. This testing is defined by IEC 61300-2-44. Refer to that…
5 Apparatus 5.1 Impact surface, which should be either: a) a plane inclined to the vertical at 10° ± 1° (for the inclined plane test), or b) a plane vertical to within 1° (for the horizontal or pendulum test). The dimensions of the impact surface shall be greater than those of the impacting face, or…
