A23.2-19C

Slump flow of concrete

1 Scope

This Test Method describes the procedures to be used in the laboratory and in the field for determining slump flow of self-consolidating hydraulic cement concrete (SCC). In the method for determining the T50 cm time, an indication of flowability of SCC is also provided for use in conjunction with the slump flow test.

Specifications and Guidelines for Self-Compacting Concrete, 2002, Annex D, Test Methods

3 Definitions

The following definitions apply to this Test Method:

Halo — an observed cement paste or mortar ring that has clearly separated from the coarse aggregate, around the outside circumference of concrete after flowing from the slump cone.

Self-consolidating concrete (SCC) — non-segregating, stable concrete mixtures proportioned to consolidate during the placement process without the use of any consolidation efforts.

Slump flow — the horizontal spread of concrete immediately upon removal of the slump cone as a measure of the unconfined fluidity of concrete giving a relative indication of the degree to which concrete can travel.

Spread — the distance of lateral flow that concrete travels using the slump flow test method.

Stability — the ability of a concrete mixture to resist segregation of the paste from the aggregates.

ELECTRONICALLY PROTECTED MOTORS – UL 1004-7

JULY 13, 2012

INTRODUCTION
1 Scope

1.1 This Standard is intended to be read together with the Standard for Rotating Electrical Machines –

General Requirements, UL 1004-1. The requirements in this Standard supplement or amend the requirements in UL 1004-1. The requirements of UL 1004-1 apply unless modified by this Standard.

1.2 Motors covered by this Standard, whose overheating protection is provided by an electronic circuit, shall additionally comply with the requirements contained in the Standard for Thermally Protected Motors, UL 1004-3, with regard to Construction, Performance, Manufacturing and Production Tests, Markings, and Instructions unless modified by this Standard.

1.3 This Standard applies to motors that rely upon an electronic circuit to prevent overheating of the motor.

1.4 The requirements in this Standard are intended to evaluate a specific motor/electronic protector combination. When the motor, the electronic protector, or the motor/electronic protector combination is changed, the combination shall be reevaluated.

1.5 The requirements in this Standard do not cover sealed (hermetic) type compressor motors.

1.6 This Standard does not apply to motors that comply with the Standard for Impedance Protected Motors, UL 1004-2, or the Standard for Thermally Protected Motors, UL 1004-3, independent of the electronic circuit.

2 Components 2.1 Controls used to provide overheating protection for motors covered by this Standard shall comply with the requirements for protective controls contained in the Standard for Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1.

3 Glossary 3.1 For the purpose of this Standard, the following definitions apply.

3.2 ABNORMAL SWITCHING – Any aberration from the normal, intended signal being fed to the motor coils. This includes, but is not limited to, a change in pulse frequency, duty cycle, and timing (i.e., overlap, amplitude, and the like).

3.3 PROTECTION SCHEME – A combination of sensing and control circuits. Examples include the following:

a) A combination of rotation sensing (i.e., Hall effect sensor) and a control circuit designed to take corrective action (i.e., deenergize the motor in the event that the Hall effect sensor senses a lack of intended motor speed);

b) A combination of current sensing and a control circuit designed to take corrective action in the event that excessive motor current is detected.

Electronic protection circuits may incorporate one or many protection schemes to provide primary or redundant overheating protection for a motor.
