DIN EN ISO 15912-2016牙科. 耐高溫包埋材料和模鑄材料 (ISO 15912-2016); 德文版本EN ISO 15912-2016

This International gives requirements and test methods for determining the compliance of dental casting investment, dental brazing investment, dental pressable-ceramic investment and dental refractory die materials used in the dental laboratory, regardless of the composition of the refractory powder, the composition of the binder, or the particar application. This International classifies such products into types and classes, according to their intended use and the burn-out procedure recommended by the manufacturer. It also gives requirements for marking, labelling and manufacturer's instruons. It specifies requirements for the essential physical and mechanical properties of the products and the test methods to be used for determining them.

DIN EN ISO 17402-2011土壤質(zhì)量.土壤和土壤物質(zhì)中污染物生物利用度測定方法的選擇和應(yīng)用的要求和指南(ISO 17402-2008);德文版本EN ISO 17402-2011

This International provides guidance for the selion and application of methods to assess bioavailability for the characterisation of contaminated soil and soil materials. This International does not give a selion of the best applicable methods, but specifies boundary conditions and principles of methods to be used and gives the mial requirements for the development of methods. The rests obtained from such methods can be used as an estimate of bioavailability in a risk-assessment approach.In this International , when the term \"soil\" is only quoted for simplification, the broader term \"soil and soil material\" shall be considered. The contaminants considered in this International are metals, including metalloids, and organiccontaminants, including organometal compounds. This International is also applicable to metals originating from natural geological and pedological processes (natural pedo-geochemical content). This International can also be applied to sediments.According to the protion goals envisaged, applications of existing methods are recommended and their limitations discussed, with the intention of promoting the development and introduon of workable methods to be used in soil and site assessment. These methods are required to allow for the quantification of factors influencing bioavailability.
