General Information
Frequently Asked Questions
ICS 67.140 is a classification code in the International Classification for Standards (ICS) system. It covers "Tea. Coffee. Cocoa". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 186 standards classified under ICS 67.140 (Tea. Coffee. Cocoa). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

1.1 This document specifies a sampling method for a consignment of instant coffee, shipped in 10 package units or more. This document is applicable to cases which have inner linings of moisture-resistant material hermetically sealed because of the hygroscopic nature of instant coffee and which are in package units greater than 10 kg net mass, typically up to 50 kg. This document is also applicable to units of more than 50 kg, usually called “big bags” or “supersacks”. The cases are generally made of cardboard of appropriate strength and the big bags are made of suitable plastic material. 1.2 This document is also applicable to the selection and preparation of a sufficiently representative sample of the consignment, which is intended: a) to serve as a basis for an offer for sale; b) for examination to verify that the instant coffee to be offered for sale satisfies the producer’s sales specification; c) for examination to determine one or more of the characteristics of the instant coffee for technical, commercial, administrative and arbitration purposes; d) for retention as a reference sample for use, if required, in litigation. 1.3 This document is applicable to all types of instant coffee, as defined in ISO 3509, contained in all types of units with liners, with the exception stated in 1.4. 1.4 For bulk density and particle size, this document is applicable to spray-dried powder and freeze-dried instant coffees only, as defined in ISO 3509, due to the intrinsic fragility of particles of agglomerated instant coffee, which leads to greater breakdown and headspace in the final packed units for the consumer.

This document specifies a method to classify six tea types (black tea, green tea, white tea, oolong (blue) tea, dark tea and yellow tea) based on statistical analysis of chemical compositions. The key X1 to X6 determinants (total catechins, caffeine, theanine, epigallocatechin gallate (EGCG)/total catechins, theanine × theanine, theanine × caffeine) for tea chemical classification were extracted from these critical compositions by statistical methods, from a large-scale chemical analysis of samples of six tea types, which can be used as principal components to classify the particular tea by Fisher’s step-by-step discrimination formulae.[6][7] This document is applicable to the classification of both primary and refined teas, and is particularly suitable for teas produced in China.

SIGNIFICANCE AND USE
5.1 The measured maximum energy input rate is used to confirm that the coffee brewer is operating in accordance with its nameplate rating.
5.2 If applicable and accessible, the boiler or internal tank temperature is measured to ensure that the water is maintained at a ready-to-brew temperature. This can also be used later to normalize coffee brewer energy consumption to a standard temperature.
5.3 The Preheat Test can be used to gauge the amount of time and energy required for the coffee brewer to reach a ready-to-brew state from the ambient room and incoming water temperatures.
5.4 Ready-to-Brew and Energy Save Mode energy can be used by end users to estimate the amount of energy consumed while coffee is not being brewed.
5.5 Heavy-use energy consumption can be used to estimate how much energy is consumed by the coffee brewer when brewing coffee. Along with preheat and ready-to-brew (standby) energy, this value can be used by end users to model their machine energy use.
5.6 Production capacity is a calculated measure, determined through testing, to define the performance of the coffee brewer. End users can use this value to specify a brewer that matches their production needs.
SCOPE
1.1 This test method covers the evaluation of the energy consumption, brewing, and holding performance of commercial coffee brewing machines (here after referred to as coffee brewers) used in commercial and institutional facilities. The operator can use this evaluation to select a coffee brewer and characterize its energy use and performance. This test method does not cover residential coffee brewers, “urn” coffee brewers (Type III), or espresso machines.
1.2 This test method applies to single cup (Type I) and batch (Type II) coffee brewers. The coffee brewer will be tested for the following (where applicable):
1.2.1 Maximum energy input rate,
1.2.2 Heavy use brewing energy consumption,
1.2.3 Production capacity,
1.2.4 “Ready-to-Brew” (Standby/Idle) energy rate, and
1.2.5 “Energy Save Mode” (Low power) energy rate.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This Technical Specification specifies a method for the determination of acrylamide in cereal-based products, potato-based products and coffee by gas-chromatography mass spectrometry (GC-MS).
The method has been single-laboratory validated via the analysis of spiked samples (French fries (uncooked), bread, water biscuit, infant cereal, biscuit, green coffee, roast coffee and instant coffee), ranging from 30 μg/kg to 1 500 μg/kg acrylamide.
The results from the single laboratory validation were obtained by a laboratory with significant experience in acrylamide analysis. In addition, this method has also been studied by inter laboratory trial via the analysis of samples containing incurred acrylamide, ranging from approximately 200 μg/kg to 2 000 μg/kg. Critical points of the method are identified in 7.5 and Clause 8.

This European Standard specifies a method for the determination of acrylamide in bakery ware such as bread, toasted bread, crisp bread, butter cookies, and biscuits, as well as potato products such as potato chips, potato crisps, and potato pan cake and roasted coffee, by liquid chromatography in combination with electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS). This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spiked samples, ranging from 14,3 µg/kg to 9 083 µg/kg. It was developed at the Swedish National Food Administration and validated in a study organized by the Directorate General Joint Research Centre (DG JRC), Swedish National Food Administration and the Nordic Committee on Food Analysis (NMKL), see [1] and [2].
The limit of quantification (LOQ) depends on the type of instrument used and on the actual performance of the instrument. The majority of the laboratories participating in the validation study were able to determine acrylamide in a butter cookie sample at a level of 14,3 µg/kg. Thus, the validation by interlaboratory study showed that LOQ can be expected to be in the range between below 15 µg/kg and 30 µg/kg.
