This specification covers hollow and solid (see 5.3 and 5.4) concrete masonry units made from hydraulic cement, water, and mineral aggregates with or without the inclusion of other materials. There are three classes of concrete masonry units: Normal Weight, Medium Weight, and Lightweight. These units are suitable for both load bearing and non-load bearing applications. This standard covers hollow blocks from sizes of 3in. (76.2mm) to 8 in. (203.2mm).

Concrete masonry units covered by this specification are made from lightweight or normal weight aggregates, or both.

This standard specifies performance requirements for hollow load-bearing concrete masonry units made from Portland cement, water and mineral aggregates with or without the inclusion of other materials. It covers three weight classifications of the concrete masonry units: (a) normal weight; (b) medium weight; and (c) lightweight.

This standard specifies requirements for hollow non-load-bearing concrete masonry units made from portland cement, water and mineral aggregates with or without the inclusion of other materials. It covers three weight classifications of the concrete masonry units: (a) Normal weight; (b) Medium weight; and (c) Light weight. It also covers the sampling and testing of hollow non-load-bearing concrete masonry units for compressive strength, absorption, weight, moisture content and dimensions. It does not cover blocks intended solely for decorative purposes.

This document specifies the general requirements for the competence, impartiality and consistent operation of laboratories. It is applicable to all organizations performing laboratory activities, regardless of the number of personnel.

Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use this document in confirming or recognizing the competence of laboratories.

This standard specifies the conditions under which ready-mixed concrete shall be made and delivered, and the methods by which the purchaser can specify with his enquiry or order, the properties of the concrete required.  It provides a specification for the production and supply of ready-mixed concrete. Methods of specifying ready-mixed concrete for nominal mixes, specified strength mixes and mixes for special purposes, to meet the requirements of standard codes of practice, are covered.  It also gives guidance on the data to be provided by the purchaser when ordering ready-mixed concrete, the inspection facilities to be provided by the supplier and the appropriate tests.  Routine tests which must be carried out by the supplier and those which are the responsibilities of the purchaser are also included.  This standard does not cover the placing, compaction, curing or protection of the concrete after delivery, nor does it apply to materials for lean concrete or similar road care materials.

This standard specifies the general requirements for a laboratory safety management system, which will enable a laboratory to formulate a policy and objectives, taking into account legislative requirements and information about significant risks, which the laboratory can control and over which it can be expected to have an influence, to protect its employees and others, whose health and safety may be affected by the activities of the laboratory. In addition this standard specifies specific requirements for medical laboratories. This standard is applicable to any laboratory that wishes to: (a) implement, maintain and improve an Occupational Safety and Health Management System; (b) assure itself of its conformance with its stated safety policy; and (c) make s self-determination and self –declaration of conformance with this standard.

 This standard specifies the general requirements for a laboratory safety management system, which will enable a laboratory to formulate a policy and objectives. It takes into account legislative requirements and information about significant risks, that the laboratory can control and over which  it can be expected to have an influence, to protect its employees and others, whose health and safety may be affected by the activities of the laboratory. 

This standard specifies requirements for brewery products including beer, stout, shandy and malta; to be sold or traded in the CARICOM region.

 It is not applicable to beverages that are not derived from cereals, sold under common names including the words "beer" and "ale".

EXAMPLE Ginger beer, ginger ale, root beer are not covered by this standard.

This international standard specifies requirements for quality and competence in medical laboratories. It can be used by medical laboratories in developing their quality management systems and assessing their own competence. It can also be used for confirming or recognizing the competence of medical laboratories by laboratory customers, regulating authorities and accreditation bodies.
