1 Scope
1.1 General
This Standard describes a method for the quantification of the aliphatic (R–OH), carboxylic acid (R–COOH), and phenolic (Ph–OH) hydroxyl groups present in lignin. Phenolic hydroxyl groups include
a)
syringyl (S), guaiacyl (G), and p-hydroxyphenyl (H) units; and
b)
condensed phenolics incorporating ß-5, 4-O-5’, and 5-5’ inter-unit linkages.

Methods of testing petroleum and associated products Standard test method for the identification of ...
This test method is a standard procedure for the determination of paraffins, olefins, naphthenes, aromatics
and unknowns (P.O.N.A.U.) in automotive gasolines using gas chromatography and flame ionization detection
(GC/FID). Individual hydrocarbon components greater than or equal to 0.01 % by mass are determined. Group types
greater than or equal to 0.01 % by mass are determined by summing…
Jewellery and precious metals — Sampling of precious metals and precious metal alloys
This document specifies a method of sampling precious metals and precious metal alloys for the determination of their precious metal content and for the assessment of their homogeneity. The document is applicable to raw materials, semi-finished products and finished products and is intended to be used only for the sampling of entirely metallic materials.
