1 Scope

1.1

This Standard covers mechanical couplings that are used to axially join pipes and fittings in non-pressure drain, waste, and vent (DWV) piping systems and sewer piping systems located inside or outside buildings and above ground or underground.

Notes:

1) Caution should be exercised when installing mechanical couplings at low temperatures. The coupling manufacturer should be consulted.

2) Caution should also be exercised when installing mechanical couplings at the base of stacks, at cleanouts, or at offsets in a piping system (see Annex A).

1.2

This Standard specifies requirements for the following types of mechanical couplings:

a) Type 1: couplings that are used to join pipes of the same or different materials or sizes and that incorporate a centre stop and an external shield.

b) Type 2: couplings that are used to join pipes of the same or different materials or sizes, but for which a centre stop and/or shear ring are allowed but not required.

c) Type 3: couplings used to join hubless cast iron pipe and fittings. Such couplings are composed of a stainless steel shield, a clamp assembly, and an elastomeric sealing component that complies with ASTM C564.

d) Type 4: elastomeric bellows expansion joint couplings used to join pipe of the same or different materials or sizes incorporating pipe stops.

       e) Type 5: couplings that have an integral restraint feature which enables the couplings to be used as an alternative to external joint restraint at changes of direction and locations subject to extended periods of maximum flow.

Notes:

1) Pipe and pipe-fitting materials that may be joined include

a) fibrocement (CSA B127.3);

b) cast iron (CSA B70);

c) concrete (CSA A257 Series and ASTM C14);

d) copper (ASTM B306);

e) acrylonitrile-butadiene-styrene (ABS) (CSA B181.1, CSA B182.1, ASTM D2661, and ASTM F628);

f) polyvinylchloride (PVC) (CSA B181.2, CSA B182.1, CSA B182.2, ASTM D2665, and ASTM F891);

g) galvanized steel (ASTM A53/A53M); and

h) vitrified clay (ASTM C700).

2) Type 5 couplings are an alternative to bracing as indicated in Annex A.

1.3

This Standard does not cover the joining of pipes and fittings with bell and spigot ends that use an elastomeric gasket seal.

1.4

Users should note the existence of other standards developed for different types of couplings or coupling materials, e.g., ASTM C1173, ASTM C1277, ASTM C1440, ASTM C1460, ASTM C1461, ASTM C1540, ASTM D5926, and ASTM A1128.

1.5

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.6

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

This Standard applies to new or unused wheeled or tyred, self-propelled, non-rail-bound, mobile machines for use in underground mines.

This Standard describes the technical aspects and procedures necessary for the design, performance, and testing of core design and safety requirements.

This Standard covers general requirements only. Requirements common to a variety of underground mining mobile equipment are grouped in this Standard. The remaining Standards in the series state requirements for braking and specific types of power trains. See Annex DA for additional information on how to apply the CSA M424 series of Standards.

For utility / service / support machines, this Standard only includes provisions to address the risks associated with the mobility (movement of the whole machine from one location to another). Risks for the additional functions (e.g., scaling, concrete spraying, bolting, charging drilling attachment) are not covered in this Standard.

1.1 General

This Standard describes minimum performance criteria for the service braking system, secondary braking system, and parking system for rubber-tired, self-propelled underground mining machines.

This Standard provides minimum braking system performance for rubber-tired, self-propelled underground machines, and test criteria by which machine braking system performance may be verified.

These requirements are in addition to the requirements for braking systems and performance testing specified in CSA M424.0.

Notes:

1)     Additional requirements for brake systems on machines used in coal and gassy underground mines are found in CSA M424.1.

2)     Additional requirements for dynamic and continuous retarding systems for electrically driven mobile machines are found in CSA M424.4.

1.2 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

This clause of Part 1 is replaced by the following.

This part of IEC 60335 specifies safety requirements for electrically operated commercial refrigerating appliances and ice-makers that have an incorporated motor-compressor or that are supplied in two units for assembly as a single appliance in accordance with the instructions (split system).

NOTE 101 Examples of appliances that are within the scope of this standard are:

refrigerated display and storage cabinets;
refrigerated trolley cabinets;
service counters and self-service counters;
blast chillers and blast freezers;

As far as is practicable, this standard deals with the common hazards presented by these types of appliances including those that use flammable refrigerants and appliances employing R-744 refrigerant.
This International Standard is not applicable to appliances with a mass of flammable refrigerant exceeding the limits specified in 22.110 or to appliances with that use refrigerants with a toxicity classification of B according to ISO 817.
It does not cover those features of construction and operation of refrigerating appliances that are dealt with in ISO standards.

NOTE 102 Attention is drawn to the fact that

for appliances intended to be used in vehicles or aboard ships or aircraft, additional requirements can be necessary;
in many countries, additional requirements are specified by national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.

NOTE 103 This standard does not apply to

appliances using flammable refrigerant in transcritical refrigeration systems;
domestic refrigerating appliances (IEC 60335-2-24);
split systems having a refrigerant charge of flammable refrigerant exceeding 150 g in any refrigerating circuit;

commercial ice-cream appliances;
cold temperature rooms;
multiple refrigerated chambers with a remote motor-compressor.

1DV.1.3 This standard deals with the common hazards presented by these types of appliances including those that use FLAMMABLE REFRIGERANTS and appliances employing R-744 refrigerant. However, in general, it does not take into account children playing with the appliance or persons (including children) whose capabilities (including physical, sensory or mental), or lack of experience and knowledge prevent them from using the appliance safely without supervision or instruction.

1DV.1.4 This standard is not applicable to appliances that use refrigerants other than refrigerant safety groups as defined by ISO 817 or ANSI/ASHRAE 34 as follows:
a) A1;
b) B1 only if used in appliances installed for use within machinery rooms as defined in accordance with ANSI/ASHRAE 15 (USA) or CSA B52 (Canada), or outdoors only; and
c) A2L, A2, and A3, refrigerants.
1DV.1.5 All references to ISO 817 in this Part 2 also apply to ANSI/ASHRAE 34. ANSI/ASHRAE 34 shall take precedence over ISO 817, unless the refrigerant list in ISO 817 is more up-to-date than the similar refrigerant list
in ANSI/ASHRAE 34 in which case the refrigerant list in ISO 817 can be referenced.
NOTE 101 Attention is drawn to the fact that
a. for appliances intended to be used in vehicles or aboard ships or aircraft, additional requirements can be necessary;
