Link to relevant study record(s)

Reference

Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

GLP compliance:

yes (incl. QA statement)

Remarks:

Ministry of Labor, Health and Social Affairs of North Rhine-Westphalia, Düsseldorf, Germany

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The test substance melted when approached by the ignition flame. The substance didn't burn down or burn up. No further testing was required.

The test substance is classified as not highly flammable when tested according EU Test A.10.

Interpretation of results:

not classified based on GHS criteria

Executive summary:

In a burning rate test according EU Method A.10 the test substance melted and did not burn down or burn up in the preliminary test. No further testing was required. Sodium p-chloro-m-cresolate (hydrated form) is not a flammable solid according to Regulation (EC) 1272/2008 (CLP).

Reference 2

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

Interpretation of results:

GHS criteria not met

Executive summary:

Based on experience in handling and use and the chemical structure flammability on contact with water is not to be expected. sodium p-chloro-m-cresolate (hydrated form) is not flammable on contact with water.

Reference 3

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Interpretation of results:

GHS criteria not met

Executive summary:

Based on experience in handling and use and the chemical structure pyrophoricity is not to be expected. Sodium p-chloro-m-cresolate (hydrated form) has no pyrophoric properties.

Reference 4

Endpoint:

self-heating substances / mixtures

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)

GLP compliance:

not specified

Test procedure:

25 mm sample cube at 140°C

Max. temp. reached:

559

Result:

positive outcome (effect observed)

Remarks:

Max. temp. reached after 9.8 h

The test item has to be classified as self-heating substance of division 4.2, packing group II.

Interpretation of results:

Category 1 (self-heating substances and mixtures) based on GHS criteria

Conclusions:

In the Bowes Caeron Cage Test according to UN-MTC N.4 a positive results was obtained using a 25 mm cube sample at 140 °C. The test item has to be classified as self-heating substance Cat. I according to Regulation (EC) 1272/2008 (CLP).

Description of key information

self-heating substance Cat. 1

not flammable on ignition

not a pyrophoric solid

not flammable in contact with water

Additional information

In the Bowes Cameron Cage Test according to UN-MTC N.4 a positive result was obtained using a 25 mm cube sample at 140 °C. The test item has to be classified as self-heating substance Cat. I according to Regulation (EC) 1272/2008 (CLP).

The substance melted in the preliminary screening test according to EU Method A.10 and did not propagate combustion.

Based on experience in handling and use and the chemical structure pyrophoricity and flammability on contact with water are not to be expected.

Justification for classification or non-classification

The available data on self-heating properties meet the criteria for classification as a self-heating substance Category 1 according to Regulation (EC) 1272/2008: A positive result was obtained using a 25 mm cube sample at 140 °C in a UN Test N.4.

The available data on flammability on iginition, pyrophoricity and flammability on contact with water do not meet the criteria for classification according to Regulation (EC) 1272/2008, and therefore are conclusive but not sufficient for classification: The substance melted and did not propagate combustion in a preliminary screening test according EU Method A.10. Based on chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
