BS - Method for measurement of the equivalent pore size of fabrics (bubble pressure test). Method for measurement of the equivalent pore size of fabrics (bubble pressure test) (British Standard) Means of measuring equivalent pore radius, which provides an estimate of the size of interstices in all types of fabric permeable to air, particularly in water repellent and filter fabrics.

BS - Porosity and pore size distribution of materials. According to Table 1, in the measurement range of 1– μm, pore size smaller than 9 μm should be measured by a manometer with the range of 0–, Pa and accuracy grade of (±% of span).Cited by: 5. The standard pressure specified in the ASTM standard procedure is Pa ( mm water gauge) whereas that specified in the British Standard procedure is Pa for apparel fabrics and Pa.

This test method describes the measurement for bursting strength of woven and knitted textiles taken from rolls of fabric or fabric taken from garments.

The standards produced are titled British Standard XXXX [-P]:YYYY where XXXX is the number of the standard, P is the number of the part of the standard (where the standard is split into multiple parts) and YYYY is the year in which the standard came into effect.

BSI Group currently has o active standards. Products are commonly. Scatter range of measurement values of pore size is evaluated by Type A uncertainty. Experiments are conducted on several kinds of filter fabric.

The results show that the uncertainty values are all less thanwhich validates the stability and reproducibility of this method for the measurement of pore size. Standard Method of Measurement SMM7 - Designing Buildings Wiki - Share your construction industry knowledge.

The Standard Method of Measurement (SMM) is published by the Royal Institution of Chartered Surveyors (RICS). It was first published insuperseding a Scottish Standard Method of Measurement which was published in It is now in its seventh edition (SMM7), which was first.

The paper presents an experimental procedure developed for determination of the pore size, shape and distribution in a single layer woven fabric, for the construction of a virtual model to be incorporated in a future CFD software package.

The procedure is based on non-destructive observation and analysis of woven samples. 14 different samples of gray fabrics of % cotton in plain and twill Cited by: 5. This test was adapted from the British Standard Test No.

It prondes an estimate of the size of interstices in all types of fCbrics which are permeable to air. The pressure required to force air bubbles through a fabric wetted by and covered with a film of liquid is related to the size of the pore. The Civil Engineering Standard Method of Measurement – CESMM – has been well established for over 20 years as the standard for the preparation of bills of quantities in civil engineering work.

This much anticipated fourth edition, CESMM4, brings the method into line with changes in industry practices and extends its usages into all new areas. One of the methods used is the “dish method” described by the British Standard (BS ).

The purpose of this paper is to determine the influence of the test parameters on the WVP measurements. Those elements given a measurement unit of ITEM assume that a lump sum value will be allocated, thereby making it unnecessary to lay down measurement rules.

On the other hand all other measurement units, e.g. M3, M2, M etc., have been given measurement rules which reflect the complexity of the measurement item.

We used an optical method to measure porosity parameters of woven fabrics, since it is the most accurate technique for macro-pores with diameters of more than 10 m. For each fabric specimen, we observed between 50 and macro-pores using a Nikon SMZ-2T computer-aided stereomicroscope with special software.

Method 1 Scope This British Standard describes a method for the determina-tion of the resistance to pilling and change of appearance of apparel fabrics. NOTE.

Mesh size is the mesh number (a US measurement standard) and its relationship to the size of the openings in the mesh and thus the size of particles that can pass through these openings.

Figuring out the mesh number is simple. All you do is count the number of openings in one linear inch of Size: KB. Comparing methods of measurement: why plotting difference against standard method is misleading J Martin Bland, Douglas G Altman Summary When comparing a new method of measurement with a standard method, one of the things we want to know is whether the difference between the measurements by the two methods is related to the magnitude of the Cited by: Standard Method of Measurement of Building by RICS.

Fig 1. Test and standard measurements, with line of equality Fig 1 shows a typical data set, the measurement of systolic blood pressure by a test method, the finger pressure, and a standard method, the usual arm blood pressure. This is a random sub-sample of observations from a larger data set discussed elsewhere.

This test method covers the measurement of the air permeability of textile fabrics. This test method applies to most fabrics including woven fabrics, nonwoven fabrics, air bag fabrics, blankets, napped fabrics, knitted fabrics, layered fabrics, and pile fabrics.

In the British Standard test the airflow through a given area of fabric is measured at a constant pressure drop across the fabric of 10mm head of water. The specimen is clamped over the air inlet of the apparatus with the use of rubber gaskets and air is sucked through it.

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages 1 File Size: 1MB.
