BS ISO 19162:2015 pdf free.Geographic information — Well-known text representation of coordinate reference systems. BS ISO 19162 defines the structure and content of a text string implementation of the abstract model for coordinate reference systems described in ISO 19111:2007 and ISO 19111-2:2009. The string defines frequently needed types of coordinate reference systems and coordinate operations in a self- contained form that is easily readable by machines and by humans. The essence is its simplicity; as a consequence there are some constraints upon the more open content allowed in ISO 19111:2007. To retain simplicity in the well-known text (WKT) description of coordinate reference systems and coordinate operations, the scope of this International Standard excludes parameter grouping and pass-through coordinate operations. The text string provides a means for humans and machines to correctly and unambiguously interpret and utilise a coordinate reference system definition with look-ups or cross references only to define coordinate operation mathematics. Because it omits metadata about the source of the data and may omit metadata about the applicability of the information, the WKT string is not suitable for the storage of definitions of coordinate reference systems or coordinate operations. 2 Conformance requirements This International Standard defines eleven classes of…

BS ISO 18197:2015 pdf free.Space systems一Space based services requirements for centimetre class positioning. BS ISO 18197 defines the requirements for the wide area centimetre class positioning system by broadcasting augmentation data through satellites as follows. — Centimetre class positioning According to the progress of requirements for positioning services such as automatic farming, mapping and others, centimetre class positioning is very useful. — Wide area positioning It is quite effective to broadcast augmentation data through satellites for users over wide area such as a square, more than 1,000 km each side, anytime and anywhere. Even if this area is short of data network, additional ground network facilities are not needed. In addition, as ranging signal and augmentation data can be received from satellite broadcasting at the same time, it is unnecessary for user terminals to receive the signal such as transmitted by ground network. — Real-time property The user terminals need to resolve the ambiguity in real-time, using augmentation data broadcast from satellites or other means, for the realization of centimetre class positioning. On the other hand, the provider sides have to broadcast augmentation data such that the terminal sides are able to resolve the ambiguity in real-time. 2 Normative references…

BS ISO 18074:2015 pdf free.Textiles – ldentification of some animal fibres by DNA analysis method一Cashmere, wool, yak and their blends. BS ISO 18074 specifies a testing method for DNA analysis of some animal fibres to identify cashmere, wool, yak, and their blends by using extraction, amplification by the polymerase chain reaction (PCR) method and DNA detection processes. This International Standard is applicable to cashmere, yak, and wool and their blends as a qualitative method. 2 Caution Test results for fibre identification by the DNA analysis method can be obtained with a high accuracy for the above-mentioned textile products which were processed at lower dye concentration levels or dyed in light colours. However, when such textile products were processed under severe conditions or high temperatures, the mitochondrial DNA could have been damaged. In such cases, identification can be difficult because amplification of DNA by PCR cannot take place. If textile products were contaminated by using products from another species, such as cashmere grease on wool fibres, this situation may be solved by checking using microscopy techniques. 3 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

ISO/DIS 14704-2015 pdf free.Fine ceramics [advanced ceramics, advanced technical ceramics)一Test method for flexural strength of monolithic ceramics at room temperature. ISO/DIS 14704 specifies a test method for determining the flexural strength of monolithic fine ceramics, and whisker- or particulate-reinforced ceramic composites, at room temperature and applies to materials with grain size less than 200 pm. This test method may be used for materials development, quality control, characterization and design data-generation purposes. NOTE Since fracture is due to tense stress, flexural strength data can be used to calculate a uniaxial tensile strength considering the effect of the tested volume and Weibull-statistics. So, flexural strength is often used in substitute for uniaxial tensile strength. 2 Normative references The following referenced documents are indispensable for the application of this document.
