This International Standard provides guidance on a phased approach to establish, implement, maintain and improve an environmental management system (EMS), that organizations, including small- and medium-sized enterprises (SMEs), can adopt to enhance their environmental performance.

The phased approach, described in this International Standard, provides flexibility that allows organizations to develop their EMS at their own pace, over a number of phases, according to their own circumstances. Each phase consists of six incremental stages. The outcome with respect to EMS maturity after completion of a phase can be characterized using the five-level maturity matrix provided in Annex A.

This International Standard is applicable to any organization, including small and medium-sized enterprises (SMEs), regardless of current environmental management performance, the nature of the activities undertaken or the location at which they occur.

By using this International Standard an organization will be able to develop a system that ultimately satisfies the requirements of ISO 14001.

The guidance does not cover those elements of specific systems that go beyond ISO 14001 and it is not intended to provide interpretations of the requirements of ISO 14001.

This part of ISO CD21302 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of polybutene‑1 (PB‑1) moulding and extrusion materials. For the sake of simplicity, the designation polybutene-1 and the abbreviation PB-1 are used in both parts of ISO CD21302. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are also specified.

Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PB moulding and extrusion materials are listed.

The properties have been selected from the general test methods in ISO 10350‑1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this part of ISO CD21302, as is the designatory property specified in Part 1.

In order to obtain reproducible and comparable test results, it is necessary to use the methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

1.1     This part of ISO CD21302 establishes a system of designation for polybutene‑1 (PB‑1) thermoplastic materials which may be used as the basis for specifications. For the sake of simplicity, the designation polybutene and the abbreviation PB are used in both parts of ISO CD21302-1.

1.2     The types of polybutene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory property melt volume-flow rate and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.

1.3     This part of ISO CD21302 is applicable to all butene homopolymers and to copolymers of butene with a maximum content of other 1‑olefinic monomers of less than 50 % [mass fraction] and with a content of non-olefinic monomers with functional groups up to a maximum of 3 % [mass fraction].

It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, additives, fillers, etc.

1.4     It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO CD21302 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing.

If such additional properties are required, they shall be determined in accordance with the test methods specified in ISO CD21302-2, if suitable.

1.5     In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).

This document specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened borosilicate safety glass for use in buildings.

This standard deals exclusively with thermally toughened borosilicate safety glass manufactured by the horizontal toughening process.

Other requirements, not specified in this document, can apply to thermally toughened borosilicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating glass units, or undergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard. Thermally toughened borosilicate safety glass, in this case, does not lose its mechanical or thermal characteristics and its resistance to temperature differentials.

Surface finished glasses (e.g. sandblasted, acid etched) after toughening are not covered by this document.

This document specifies laboratory methods for determination of the soil water-retention characteristic.

This International Standard applies only to measurements of the drying or desorption curve.

Four methods are described to cover the complete range of soil water pressures as follows:

a)     method using sand, kaolin or ceramic suction tables for determination of matric pressures from 0 kPa to −50 kPa;

b)    method using a porous plate and burette apparatus for determination of matric pressures from 0 kPa to −20 kPa;

c)     method using a pressurized gas and a pressure plate extractor for determination of matric pressures from −5 kPa to −1 500 kPa;

d)    method using a pressurized gas and pressure membrane cells for determination of matric pressures from −33 kPa to −1 500 kPa.

Guidelines are given to select the most suitable method in a particular case.

This document specifies a test method for determining the comparative compression shear strength of adhesive bonds and solid wood at both ambient temperature and elevated temperature. The maximum load of the test pieces at ambient temperature and after exposure to a defined elevated temperature for a specified duration of time is evaluated. It is applicable to adhesives used in load bearing timber structures and to other wood adhesives.

It is suitable for assessing the influence of elevated temperatures on the compression shear strength of the adhesive bond.

This method is intended primarily to obtain performance data for the influence of elevated temperatures on the behaviour of adhesive bonds. It can be used for the assessment of adhesives for load bearing timber structures and as well for the assessment of non load-bearing wood adhesives with respect to their suitability for forming bonds in defined climatic environments, at elevated temperatures.

This method is not intended to provide data for structural design, and does not necessarily represent the performance of the bonded member in service.
