Test parameters for the reviewed method

Values belong to the stated source edition. Test recipe, fixture and delivered instrument configuration are selected together.

ISO 105-C06 (earlier edition) · 4.1-4.2

• ISO vessel arrangement: 550 ± 50 ml; diameter 75 ± 5 mm and height 125 ± 10 mm; rotation 40 ± 2 r/min; solution temperature within ±2 °C of the selected value.

ISO 105-C08:2010 · 5.1-5.2

• Wash vessel 550 ± 50 mL; diameter 75 ± 5 mm, height 125 ± 10 mm; rotation 40 ± 2 r/min. Solution within ±2 °C of the selected test temperature; weighing accuracy 0.01 g.

TS EN ISO 105-C09:2003 · 5.1-5.3

• Recipe: vessel rotation 40 ± 2 r/min and solution-temperature deviation no greater than ±2 °C. Preparation mixer at least 1000 r/min and balance precision ±0.01 g; auxiliary preparation equipment is selected separately.

TS EN ISO 105-D01:2011 · 6.1, 8

• Dry-cleaning recipe: 550 ± 50 mL vessel with solvent-resistant seals, 40 ± 2 r/min and 30 ± 2 °C. Solvent and required fume hood are assessed separately from the aqueous-washing configuration.

AATCC 61-2009 · 5.1.1-5.1.5

• Rotation 40 ± 2 r/min; vessels differ: 500 mL (75 × 125 mm) for 1A and 1200 mL (90 × 200 mm) for 1B/2A/3A/4A/5A. Steel-ball diameter 6 mm; vessel and abrasive set are recorded for the selected test number.

TS EN ISO 105-C10:2011 · 4.1-4.4

• Vessel 550 ± 50 mL, diameter 75 ± 5 mm, height 125 ± 10 mm; rotation 40 ± 2 r/min and solution within ±2 °C of the selected temperature. Approximately 6 mm steel balls and soap/alkali recipe recorded for the selected test condition.

TS EN ISO 105-E03:2010 · 4.1

• Chlorinated-water fastness arrangement: glass or stainless 550 ± 50 mL vessel, 40 ± 2 r/min and ±2 °C solution-temperature control. Active-chlorine level and solution pH are tracked in separate recipe fields.

M&S C37:2006-02 · Apparatus

• Chlorinated-water fastness: 500 ± 50 mL vessel, chlorine-resistant seal, 27 ± 2 °C and 40 ± 2 r/min. This edition excludes infrared-heated wash wheels.

M&S C10A — June 2007 · Apparatus 1–3; Specimen; Wash liquor; Method 1–8; Note5; pp.1–4

• M&S C10A June 2007: vessel capacity 550 ± 50 mL, rotation 40 ± 2 rpm; infrared-heated wash wheels are not accepted in this edition. These historical method requirements do not automatically apply to sample-dyeing machines. The auxiliary stirrer must sustain about 1000 rpm for at least 10 min; balance accuracy at least ±0.01 g.
• Fabric specimen 100 × 40 mm; liquor ratio 100:1 (100 mL solution per 1 g fabric). Start at 27 ± 2 °C and ramp at 1.5 ± 0.5 °C/min. A 40 °C care label uses a 50 °C test; a 50 °C label uses 60 °C. Start the 30 min hold on reaching the target. These method volumes/specimen masses are not machine capacity or net weight.
• The method assesses oxidative-bleach colour change; no multifibre adjacent fabric or staining assessment. Prepare fresh solution for immediate use and adjust TAED mass to documented activity. Drying limit 60 °C. Current M&S approval and delivered ramp accuracy require separate verification.

Control and recording specification

The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.

• Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
• The calculation and endpoint are defined by the selected method edition; instrument signals and operator assessments are kept distinct.
• Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
• Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
• The C10A record links care-label/test temperatures, measured ramp and a 30 min hold starting at target temperature. Trace specimen mass/liquor volume and reagent activity; do not add optical-brightener effects or multifibre staining scores to this result. These are method requirements; delivered modules are specified separately.
